Patient Access and Financial Clearance

Every claim is built on what the front desk captured. Patient access is the set of steps that happen before and at the point of care: scheduling the order, identifying the patient, recording the coverage, asking the Medicare questions, delivering the notices the law requires, estimating the bill, collecting what is due, and finding a payer for people who have none. This tutorial walks through each step, the 2026 rules that shape it, and the denials that start at registration.

BeforePre-service

Is this patient financially cleared?

Right person, active coverage, correct order of payers, authorization, estimate, notices.

Clearance happens days before the visit, not at the counter. Anything left to the day of service is a risk.

DuringArrival

Did we confirm, sign and collect?

Two identifiers, card and ID, MSP questions, consents, ABN where needed, point-of-service payment.

Thirty seconds of confirmation at check-in prevents weeks of rework after the claim.

AfterQuality

What did the denials tell us?

Registration accuracy audits, denial root causes, feedback to the people who keyed the data.

A registration error costs seconds to fix at the desk and weeks to fix as a denied claim.

Chapter 01

The big picture

Patient access is the front end of the revenue cycle: scheduling, pre-registration, registration, insurance verification, authorization, patient estimates, financial counseling and point-of-service collection. Financial clearance is the outcome those steps are meant to produce: before the service is delivered, the organization knows who the patient is, who will pay, in what order, how much the patient owes, and that every notice the rules require has been given.

The work looks clerical and it is anything but. A member ID with a transposed digit, a dependent registered under the wrong subscriber, a Medicare patient whose working spouse's plan was never recorded, an outpatient who never got the notice that would have let the hospital bill her: each becomes a denial, a write-off or a compliance finding downstream, and each was cheapest to catch at the desk. The 2026 rules add pressure from the other direction. Price transparency enforcement, good faith estimates, Medicare notice updates and Medicaid eligibility changes all land first on the patient access team.

Why it matters in numbers

Denials start here

50% and 32%

In Experian Health's 2025 State of Claims survey, half of providers named missing or inaccurate data as a top cause of denials, and 32% named flawed patient registration data. 41% said their denial rate is 10% or higher.

The patient is a payer

$1,886 deductible

Average single-coverage deductible for workers who have one in the KFF 2025 Employer Health Benefits Survey. 34% face a deductible of $2,000 or more, and 33% are in a high-deductible plan. Collecting that money starts at access.

Estimates are catching on

45% got an estimate

Share of patients who received a cost estimate before care in Experian's 2026 State of Patient Access survey, up from 41% a year earlier. Those whose final bill was "much more" than the estimate fell from 44% to 26%.

Who is involved

Scheduler
Takes the order or the request, finds the slot, and starts the record. The first chance to capture insurance and to flag that an authorization or an estimate will be needed.
Pre-registration and financial clearance
A central team that works scheduled encounters days ahead: verifies eligibility, obtains authorization, builds the estimate, screens for assistance, and calls the patient. Often called pre-services or pre-access.
Registrar / patient access representative
The person at the desk, in the emergency department, or on the admitting floor who confirms identity, scans the card and ID, collects signatures, asks the MSP questions and takes the payment.
Financial counselor
Screens uninsured and underinsured patients for Medicaid, marketplace coverage, disability, crime victim and other programs, and for the hospital's financial assistance policy. Sets up payment plans.
Health information management (HIM)
Owns the master patient index (MPI): merges duplicates, resolves overlays, and sets the identity rules registrars must follow.
Utilization review and case management
Decide inpatient versus observation status and trigger the Medicare notices (MOON, IM, HINN) that hang on that decision.
Billing and denial management
Live with the result. Their denial data is the feedback loop that tells access what to fix.
Patient
Has rights at every step: to a medical screening exam before any payment question in an emergency, to a good faith estimate if self-pay, to the Medicare notices, to financial assistance screening, and to be billed only what the plan says they owe.

What goes wrong when it is skipped

Eligibility and identity denials

CARC 31 (patient cannot be identified as our insured), 140 (ID and name do not match), 27 (coverage terminated), 22 (another payer is primary). Correctable, but each costs a resubmission and weeks of delay.

Unbillable balances

A Medicare service without a valid ABN is the provider's loss (modifier GZ). A QMB patient billed for cost sharing must be refunded. A self-pay patient who never got a good faith estimate can dispute a bill $400 or more above it.

Patient balances that never arrive

Roughly a quarter of patient payments are collected at the point of service, according to Kodiak Solutions' 2026 tracking. The rest goes to statements, where collection rates fall with every cycle.

Chapter 02

Scheduling and order management

Scheduling is where financial clearance gets its lead time. A visit scheduled ten days out can be verified, authorized, estimated and counseled before the patient arrives. A walk-in gets none of that. The scheduling conversation is therefore the first registration, and the order behind it is the first claim.

What a complete order contains

ElementWhy access needs itWhen it is missing
Ordering provider and NPIThe 837 carries the referring or ordering provider (loop 2310A). Payers deny when the orderer is not enrolled or not in network.Hold the order; a verbal order from "the clinic" is not an order.
Service, CPT/HCPCS and lateralityDrives the authorization lookup, the estimate, the ABN decision and the slot length.Schedulers guess; the auth is obtained for the wrong code.
Diagnosis (ICD-10-CM)Medical necessity edits (NCDs, LCDs, payer policies) compare diagnosis to service before and after the claim.The ABN cannot be evaluated; the auth request lacks the indication.
Priority and clinical urgencySets the clearance deadline and whether an expedited auth applies.Routine requests marked urgent and vice versa.
SettingOffice, hospital outpatient, ASC, inpatient. Changes the price, the auth and the notices.Site-of-care redirects and surprise facility fees.
Signature and dateMedicare requires a signed order (or an authenticated electronic order) for diagnostic tests and DME.Post-payment audit findings and recoupment.

Scheduling workflow with clearance built in

  1. 1

    Identify, then search Every call

    Name, date of birth and one more identifier (phone, address, last four of SSN, or MRN) before creating anything. Search the MPI with the name spelled several ways. Creating a record is the single easiest way to make a duplicate.

  2. 2

    Capture the coverage as stated Every call

    Payer, plan name, member ID, group, subscriber name and date of birth, and whether anything changed since the last visit. Ask about a second plan and, for Medicare patients, about current employment. Offer a secure photo upload of the card.

  3. 3

    Run eligibility in real time Scheduled visits

    A 270/271 while the patient is on the line resolves most "which plan" questions at once. An inactive response is a reason to ask more, not to hang up.

  4. 4

    Flag the clearance tasks At booking

    The scheduling system should set work-queue flags from the service and payer: authorization needed, estimate due, self-pay (good faith estimate clock starts), Medicare ABN review, prior balance to discuss, interpreter needed.

  5. 5

    Set expectations Before hanging up

    Tell the patient what to bring, what will be collected and how to reach financial counseling. A pre-service call that mentions the amount due is the strongest predictor of a payment at check-in.

  6. 6

    Pre-register and confirm 1–3 days before

    Digital pre-registration (demographics, insurance photos, consents, estimate acceptance, payment) turns check-in into a confirmation. Reminders with a cost estimate attached reduce no-shows and surprises.

Measure the lead time

HFMA's MAP Keys for patient access include the pre-registration rate (encounters pre-registered ÷ scheduled encounters) and the insurance verification rate (verified ÷ registered encounters). Track both daily by department. A low pre-registration rate is usually a scheduling-template problem, not a staffing problem.

Emergency departments are different

Under EMTALA (42 CFR 489.24(d)(4)) a hospital may not delay the medical screening examination or stabilizing treatment to ask about insurance or payment, and may not seek authorization until screening is complete and stabilization has begun. Reasonable registration that does not delay care is allowed. Train ED registrars on the order of operations and never let a "financial conversation" happen before triage.

Order management for referred services

Inbound referrals

Intake queue

Faxed and electronic referrals (CCD, Direct messages, FHIR ServiceRequest) land in a work queue. Each needs a valid order, insurance, and a decision within a service standard (often 1 to 2 business days) before the patient is called.

Standing and recurring orders

Expiration dates

Therapy plans of care, infusion series, dialysis and recurring labs run on orders with end dates and visit counts. Access should see the remaining visits and the plan-of-care recertification date, and the MSP questions must be refreshed every 90 days for recurring Medicare outpatients.

Order-to-schedule reconciliation

No orphan orders

Compare signed orders with scheduled appointments weekly. Orders never scheduled are lost care and lost revenue; appointments without an order are claims that will be audited.

Chapter 03

Registration and identity

Registration answers two questions: who is this person, and have we seen them before? Everything else in the record, clinical and financial, attaches to the answer. The enemies are the duplicate (one person, two records) and the overlay (two people, one record). The first splits a history and bills under the wrong insurance; the second is a patient-safety event.

The master patient index

MPI / EMPI
The master (or enterprise master) patient index: the table of every person the organization has registered, keyed by medical record number, with the demographic traits used to match them. The EMPI links MRNs across facilities and systems.
Matching algorithm
Deterministic rules (exact match on name, DOB, sex, SSN) or probabilistic scoring across many traits. Scores above a threshold auto-link; a middle band goes to HIM for review; below the band, a new record is allowed.
Duplicate
Two MRNs for one person, usually created when a search failed (nickname, maiden name, transposed DOB) and the registrar clicked "new patient." Merged by HIM after review.
Overlay
One MRN holding two people's data, usually from selecting the wrong search result (same name and DOB, or a parent and child). Harder to fix and far more dangerous: allergies, results and insurance are mixed.
Overlap
One person with different MRNs in different facilities of the same system, linked (or not) in the EMPI.
Naming conventions
House rules for hyphens, apostrophes, suffixes, two last names, legal versus preferred names, and newborns (Boy/Girl plus mother's last name, replaced after naming). Consistency is what makes matching work.

The registration conversation

  1. 1

    Ask open questions Identity

    "Please tell me your full name and date of birth," never "Are you Jordan Doe, born April 12, 1985?" Confirm with a photo ID when policy requires it and with two identifiers every time, matching Joint Commission's patient identification goal.

  2. 2

    Search before you create MPI

    Search by name and DOB, then by DOB alone, then by phone or SSN. Look at the candidates. A record with a maiden name and an old address is still the same person.

  3. 3

    Verify, don't retype Demographics

    For existing patients, read back address, phone, email, emergency contact and employer and change only what changed. Each re-keying is a chance to introduce a typo that breaks a statement address or a claim.

  4. 4

    Capture the legal and the preferred Demographics

    Legal name as the payer has it (claims match on it); preferred name and pronouns for care; sex as on the insurance record and gender identity as the patient states it, in the fields designed for each.

  5. 5

    Scan, then key Documents

    Scan the ID and both sides of every insurance card. OCR fills the fields; the registrar checks them against the image. The scan is the evidence when a payer says the ID was wrong.

  6. 6

    Guarantor and relationship Financial

    Who gets the bill (self, parent, spouse) and who holds the insurance (subscriber) are two different questions with two different fields. Relationship codes on the 837 (SBR02 and PAT01) come from here.

Fields that break claims

FieldRuleTypical errorResult on the claim
Patient nameExactly as on the insurance record; no nicknames; suffix in its own field"Bill" for William; hyphen dropped; suffix appended to last nameCARC 140 / RARC N382; eligibility 271 returns AAA 72 (invalid member)
Date of birthVerified against ID; month and day in the right orderTransposed digits; a parent's DOB on the childCARC 31 or 140; overlay risk
SexAs on the insurance record for the claim; gender identity captured separatelyDefaulted field never changedSex-specific procedure edits; eligibility mismatch
Address and phoneUSPS-standardized; verified each visitOld address; mobile number missingReturned statements; no digital outreach; address edits on the 837
Subscriber and relationshipSubscriber's name, DOB and ID when the patient is a dependentChild registered as self; spouse as subscriber when the patient isCARC 31; claim pays to the wrong accumulators
GuarantorAdult responsible for the bill; emancipated minors and adult children are their own guarantorParent left as guarantor of a 30-year-oldStatements to the wrong person; HIPAA complaint
Employer and employment statusNeeded for MSP and for workers' compensationBlank or "retired" for a working 70-year-oldMedicare billed primary when the employer plan was primary
Accident indicatorAuto, employment, other, with date and stateNot asked at allCARC 22 (COB) or MSP rejection; liability insurer never billed
Overlays are a safety event

Treat a suspected overlay like a medication error: stop, report to HIM, and do not use the record until it is split. The AHIMA survey of 815 HIM professionals found 73% work on duplicate mitigation at least weekly; overlays are rarer but every one is dangerous. Never "fix" an overlay by editing the demographics over the other person.

Medical identity theft

A patient using someone else's card creates an overlay and a false claim. Ask for photo ID, compare the photo, and compare the signature to prior consents. If the eligibility response shows a different DOB or sex than the person in front of you, escalate rather than override. Document the discrepancy; do not confront the patient about fraud at the desk.

Consents collected at registration

Consent to treat

General consent for examination and treatment. Distinct from informed consent for a procedure, which the clinician obtains. Renewed per visit or per policy period (often annually for outpatient series).

Financial agreement and assignment of benefits

The patient agrees to pay what the plan does not, and assigns insurance benefits to the provider so the payer pays the provider directly. This is what makes box 12 and 13 of the CMS-1500 ("signature on file") true.

Notice of privacy practices

HIPAA requires giving the notice at the first service and making a good-faith effort to get a written acknowledgment. The acknowledgment, or the documented refusal, is kept six years.

Release of information

Authorizes sending claim information to the payer (CLM09 on the 837) and, separately, any disclosure beyond treatment, payment and operations, such as to a family member or an employer.

Advance directive inquiry

Hospitals and other Medicare providers must ask whether the patient has an advance directive and document the answer (Patient Self-Determination Act, 42 CFR 489.102). Asking is required; having one is not.

Language and accessibility

Record the preferred language and the need for an interpreter or accommodation (Section 1557, ADA). Consents signed without a qualified interpreter are not informed consents.

Chapter 04

Insurance capture and verification

The insurance record has three parts that must agree: what the card says, what the patient says, and what the payer's eligibility system returns. Registration captures the first two; verification tests them against the third. The eligibility tutorial covers the 270/271 in depth; this chapter covers the capture workflow and what to do with the response.

Card scanning and what to key

Capture

Scan both sides, every visit

Card scanners and phone uploads with OCR read the member ID, group, plan name, payer ID and phone numbers. The registrar's job is to check the extracted fields against the image, not to type them. Date-stamp the scan; a card from 2024 is not proof of 2026 coverage.

Interpret

What the card does not say

Whether the plan is active, whether the patient is still a dependent, which network applies at your site, the deductible met to date, and whether another plan is primary. Only the 271 or a call answers those.

Payer selection

Pick the plan, not the logo

The registration system's payer list maps each plan to a payer ID, an address and a set of billing rules. Choosing "Northwind PPO" when the card says "Northwind Medicare Advantage" sends the claim to the wrong product with the wrong rules. Build the list with the plan name as printed and retire old entries.

Order of payers

Primary, secondary, tertiary

Record every plan with its COB order and the reason (MSP rule, birthday rule, court order, active versus COBRA). The 837 carries the order in SBR01 and the other payers in loop 2320. Wrong order is CARC 22 and a resubmission.

EB*1 Active coverage, with dates (DTP*346/347)Coverage is active for the plan on the date of serviceSave the response to the encounter as proof; schedule

Medicare HETS: EB*R with the MA plan's name and contract number, QMB indicator, MSP dataThe patient has a Medicare Advantage plan, a Medicaid dual status, or an MSP recordBill the MA plan, not Medicare; apply the QMB billing prohibition; reconcile MSP against the questionnaire

Coverage discovery and other-coverage search

Patients forget plans, do not know a spouse added them, or do not realize a Medicaid application was approved. Discovery tools query payers in batches with name, DOB and sometimes SSN to find coverage the patient did not report. Run them at registration for self-pay patients, before statements go out, and before an account is sent to bad debt or charity. The hit rate is highest for Medicaid (retroactive eligibility), Medicare Advantage, and commercial plans picked up after a job change.

Retroactive Medicaid

Medicaid eligibility can be backdated: 90 days before the application month in most states today, falling to one month for expansion adults and two months for others from January 1, 2027 under the 2025 reconciliation law. Discovery after discharge still pays, but the window is closing.

Medicare for the self-pay patient

Anyone 65 or older or on Social Security disability for 24 months is likely Medicare-eligible. HETS tells you whether they are enrolled and in which parts and plans. Many "self-pay" seniors turn out to have a Medicare Advantage plan.

The 2026 marketplace

With enhanced premium tax credits gone after 2025, effectuated marketplace enrollment fell to 19.2 million in February 2026 from 21.8 million a year earlier (KFF). Expect more patients whose "insurance" lapsed for non-payment; re-verify every visit.

The 2026 verification stack

Real-time 270/271
Required of every HIPAA payer; 96% of medical plan eligibility transactions were fully electronic in the 2024 CAQH Index. Provider cost: about $2.00 electronic versus $8.57 manual per inquiry, with a $11.7 billion annual savings opportunity still on the table.
Batch re-verification
Run the whole schedule 1 to 3 days ahead and again the morning of service. Catches terminations at month end and plan changes in January.
Payer portals
Needed for details the 271 omits (accumulators by family member, authorization lists, PCP). Save screenshots with dates; a portal view is evidence in a dispute.
FHIR Patient Access and Payer-to-Payer APIs
CMS-regulated payers must expose claims, encounter and coverage data through FHIR APIs, with Provider Access APIs due January 1, 2027 under CMS-0057-F. Expect eligibility and benefit detail to arrive inside the EHR rather than from a separate lookup.
Phone verification
The last resort, with the date, time, representative name and reference number recorded in the encounter. "Verification is not a guarantee of payment" is printed on every response; the record of the call is still your best evidence.
Verification checklist for a scheduled visit
  • Plan active on the date of service, under the product named on the card, with the patient (not just the subscriber) listed as covered.
  • Your site is in network for that product. A carrier's PPO network and its exchange network are not the same list.
  • Other coverage identified and ordered: MSP questions for Medicare patients, birthday rule for children, COBRA versus active, auto or workers' compensation for accidents.
  • Benefits captured for the service type: deductible remaining, coinsurance, copay, out-of-pocket remaining, visit limits.
  • Authorization or referral status known and the number on the encounter.
  • Flags noted: QMB or other Medicaid dual status, HMO PCP assignment, carve-out vendors, prior balance.
  • Evidence saved: 271 response or portal screenshot attached to the encounter with the date verified.
Chapter 05

Medicare Secondary Payer and other-coverage discovery

Medicare is the payer of last resort whenever another insurer is legally responsible. The Medicare Secondary Payer (MSP) rules say when that is true, and the MSP questionnaire is how providers find out. Billing Medicare as primary when it is secondary is an overpayment that must be returned; billing it secondary when it is primary delays payment for months. The questions take two minutes and they are required.

When Medicare is secondary

SituationMedicare is secondary when…Primary payerMSP type (SBR05 / value code)
Working agedThe patient is 65 or older and covered by a group health plan through their own or a spouse's current employment, and the employer has 20 or more employeesEmployer group health plan12
DisabilityThe patient is under 65, entitled by disability, and covered by a large group health plan through their own or a family member's current employment, and the employer has 100 or more employeesLarge group health plan43
End-stage renal diseaseThe patient has any group health plan coverage (including retiree or COBRA) and is within the 30-month coordination period that starts with ESRD-based Medicare eligibilityGroup health plan, for 30 months13
Workers' compensationThe service treats a work-related injury or illnessWC carrier (or the employer)15
No-faultThe service treats an injury from an auto or other accident covered by no-fault, medical payments or PIP coverage, regardless of faultNo-fault insurer14
LiabilityAnother party may be legally responsible for the injury (auto, premises, product, malpractice)Liability insurer or settlement47
Federal Black LungThe service treats a lung condition covered by the Black Lung programDepartment of Labor41
Veterans AffairsThe VA authorized the care; the veteran chooses one program per serviceVA42
Current employment

Active, not retired

Retiree coverage, COBRA (except in ESRD cases) and plans of employers under the size threshold leave Medicare primary. "Current employment status" includes some leaves of absence and disabled workers still carried as employees. The question is about the employer plan's basis, not whether the patient feels retired.

Employer size

20 and 100

Counted as employees on the payroll for 20 or more weeks in the current or preceding year. Two small employers in a multi-employer plan combine if any one of them meets the threshold. When in doubt, record the employer's name and let the benefits coordination contractor decide.

Conditional payment

120 days

For liability and no-fault, the provider bills the insurer first. If it has not paid within 120 days (the prompt-pay period), Medicare may be billed for a conditional payment, which Medicare recovers from the settlement. Workers' compensation claims that are contested can be billed to Medicare with a note that the claim is disputed.

The MSP questionnaire

CMS's model questionnaire (Medicare Secondary Payer Manual, chapter 3, section 20.2.1) has three parts: accidents and special programs (Black Lung, workers' compensation, no-fault, liability), entitlement and group health plan coverage (age, disability, employer size), and ESRD. Providers must ask the questions for every inpatient admission, outpatient encounter or start of care; for recurring outpatient services the answers must be re-verified every 90 days. Access to the Common Working File or a 271 does not remove the duty to ask, though a provider may ask whether anything changed if it has a complete questionnaire on file. Keep the answers for 10 years after the date of service. Medicare Advantage members are exempt; their plan coordinates benefits.

Basis of Medicare entitlement
Is today's service related to…
Group health plan coverage

Other-coverage rules that are not MSP

Birthday rule
For a child covered by both parents' plans, the plan of the parent whose birthday falls earlier in the calendar year is primary (NAIC model; most states and plans). Court orders and custody arrangements override it.
Active over COBRA, employee over dependent
A plan covering the patient as an active employee pays before one covering them as a dependent or COBRA continuant. Medicaid is always last; TRICARE is secondary to all except Medicaid and specific programs.
Medicare Advantage
The MA plan stands in Medicare's place and applies the same MSP rules itself. Bill the MA plan, never Traditional Medicare, for the months of enrollment.
Dual eligibles
Medicare primary, Medicaid secondary. QMB and other Medicare Savings Program enrollees cannot be billed for Medicare cost sharing at all (chapter 08).
Benefits Coordination & Recovery Center (BCRC)
CMS's contractor that holds the MSP record. When the Common Working File shows an MSP occurrence the patient says has ended, the patient or employer must call the BCRC to update it; the provider cannot override it on a claim.
Chapter 06

Consents and Medicare notices

Medicare beneficiaries have a statutory right to know, before they get care, when Medicare is not expected to pay and when a covered stay or service is ending. Each situation has its own notice, form number and clock. Deliver the right one on time and the patient can be billed; miss it and the cost is the provider's.

The ABN in practice

When it is required

Expected medical-necessity denial

Frequency limits exceeded (a screening earlier than the covered interval), a diagnosis the LCD does not list, experimental use, custodial care, a lab panel ordered without a supporting indication. The notifier must have a genuine reason to expect the denial; routine or blanket ABNs are not acceptable practice.

When it is voluntary

Statutorily excluded services

Cosmetic surgery, routine dental, hearing aids, most routine foot care, personal comfort items. Medicare never pays, the patient is liable with or without a notice, and an ABN given as a courtesy is reported with modifier GX. The patient need not sign.

Filling it out

Items, reason, estimate, options

Name the item or service in plain language, state why Medicare may not pay, and give a cost estimate; CMS expects it within $100 or 25% of the actual cost, whichever is greater. The patient chooses: Option 1 (bill Medicare, keep appeal rights), Option 2 (do not bill Medicare, pay now), or Option 3 (decline the service). Staff must not pre-select an option.

Keeping it

Five years, retrievable

The signed ABN stays on file for five years from discharge or completion of care (longer if state law says so) and must be produced on request. Scan it to the encounter; the modifier GA on the claim is a statement that it exists.

Coverage
Setting
Why coverage is in doubt
Notice status
Observation is an outpatient status

A patient in a hospital bed under observation is an outpatient. Part B cost sharing applies per service, self-administered drugs are generally not covered, and the days do not count toward the three-day inpatient stay that Medicare requires before covering a skilled nursing facility (a requirement MA plans may waive). The MOON exists so the patient hears this from the hospital, not from the bill.

Notices are not waivers for other payers

The ABN is a Medicare instrument. Commercial plans may allow a plan-specific waiver when the contract permits patient billing for non-covered services, and Medicaid generally prohibits billing enrollees for covered services at all. Medicare Advantage plans do not use the ABN; the route to patient liability is a pre-service organization determination and the plan's own denial notice.

Chapter 07

Price estimates and price transparency

Three separate rules push prices to the front of the encounter: the No Surprises Act's good faith estimate for uninsured and self-pay patients, the hospital price transparency rule that makes negotiated rates public, and the Transparency in Coverage rule that makes plans run cost estimators. A patient estimate combines all three with the one thing none of them has: this patient's accumulators from today's 271.

Good faith estimates (No Surprises Act)

Who and when

Uninsured and self-pay patients

Anyone without coverage, or who asks you not to bill their plan, must get a written good faith estimate (GFE) when they schedule or on request. Due within 1 business day if the service is scheduled at least 3 business days ahead, within 3 business days if scheduled at least 10 business days ahead or when a price is requested without scheduling. The convening provider or facility is responsible.

What it contains

Items, codes, expected charges

A list of the items and services the convening provider reasonably expects, with diagnosis and service codes and the expected charge for each, in plain language, plus disclaimers and dispute rights. Since 2023 it was meant to include co-providers and co-facilities (anesthesia, pathology); HHS continues to exercise enforcement discretion on that element until it issues rules.

The $400 rule

Patient-provider dispute resolution

If the final bill from a provider or facility is at least $400 more than that provider's GFE, the patient can start the PPDR process within 120 calendar days of the bill, for a $25 administrative fee. While it is pending the provider may not send the bill to collections or charge late fees. The reviewer can set the amount owed at the estimate.

Still coming

Insured patients and the AEOB

The statute also requires a GFE to the plan and an advanced explanation of benefits (AEOB) to insured patients. As of 2026 that part remains unimplemented pending rulemaking, so the insured-patient estimate is a service standard, a state requirement in some states, and a collections tool, not a federal duty.

Transparency in Coverage

The plan's estimator

Group and individual plans must post in-network rate and out-of-network allowed-amount files (since July 2022) and run an internet cost-comparison tool: 500 items from plan years starting 2023, all items from 2024. Patients arrive with the plan's number; your estimate should explain any difference (site, codes, accumulators).

Hospital price estimator tools

Self-service, with limits

Most hospitals meet the shoppable-services requirement with an online estimator. It is only as good as the chargemaster mapping behind it, and it cannot see the patient's deductible unless it runs a 271. Pair it with a staffed estimate line.

State laws

Stricter in places

Several states require estimates to insured patients on request, cap how far a bill may exceed an estimate, or tie collection rights to compliance with transparency rules. Check your state's hospital billing statute before relying on the federal floor.

Building the patient estimate

An estimate is arithmetic on four numbers: the allowed amount for the service under the patient's plan (from the contract or the transparency file), the deductible remaining, the cost sharing for that service type (copay, coinsurance), and the out-of-pocket maximum remaining. The 271 supplies the accumulators; the contract supplies the allowed amount; the order supplies the codes. Below is a fictional 271 excerpt for Jordan Doe's plan, followed by the calculator that turns it into a number.

EB*C*IND*30**23*2000***Y~ deductible, in network, calendar year: $2,000 EB*C*IND*30**29*1400***Y~ deductible remaining: $1,400 EB*G*IND*30**23*5000***Y~ out-of-pocket maximum: $5,000 EB*G*IND*30**29*4400***Y~ out-of-pocket remaining: $4,400 EB*A*IND*30*****.2**Y~ coinsurance 20% after deductible, in network EB*B*IND*98*****40**Y~ copay $40 for office visits (service type 98)
Patient estimate calculatorAllowed amount × accumulators from the 271. For self-pay, the good faith estimate and the $400 dispute threshold.
Patient type
Estimate hygiene
  • Date it and source it. Record the 271 date, the accumulators used and the fee source. An estimate is a snapshot; a surgery two weeks later may hit a different deductible.
  • Name the uncertainty. Add-on codes, implants, pathology and anesthesia are the usual reasons a bill differs from an estimate. Say so in writing.
  • Give it in the patient's channel. Experian's 2026 survey found 71% of patients who got an estimate found it easy to understand; estimates delivered to mobile devices rose sharply. Text and portal delivery with a pay link converts better than a mailed letter.
  • Keep the GFE for self-pay patients with the date sent; it is the document the dispute process will compare against.
Chapter 08

Point-of-service collections

The best time to collect a patient balance is before the patient leaves, and the second-best is before they arrive. Once a balance moves to statements, every cycle collects less. Point-of-service (POS) collection is not aggressive billing; it is telling the patient the amount early, offering ways to pay it, and asking.

What the numbers say

POS share

About a quarter

Kodiak Solutions' hospital data put the point-of-service collection rate at 24.8% in the first quarter of 2026, up from 22.7% a year earlier, with point-of-service cash about 30% of all patient payments. The share varies by payer type: highest for Medicaid fee-for-service and Medicare Advantage patients, lowest (about 15%) for Traditional Medicare, whose balances mostly flow to supplemental plans.

Pre-service is growing

16% to 21%

In HFMA's 2026 survey with PayZen, pre-service collections rose from 16% of self-pay collections in 2025 to 21% in 2026, and 91.5% of organizations now encourage, require or collect a payment before service.

Required, but flexible

17.1% require up-front payment

Of organizations that formally require payment before elective care, 68% proceed anyway when the patient cannot pay (up from 41.7% a year earlier). A "requirement" is a conversation starter; care is rarely withheld.

What can be collected at the point of service

CopayFixed amount on the card or the 271 for the service typeContractually required to be collected by most plans; waiving it routinely violates the contract and, for federal programs, the Anti-Kickback Statute and beneficiary inducement rules

The collection conversation

  1. 1

    Prepare the number Pre-service

    Registrars collect what they can see. The estimate, the copay and the prior balance must be on the check-in screen, with the 271 behind them. A registrar guessing at a copay collects nothing.

  2. 2

    State the amount as a fact Check-in

    "Your plan sets a $60 specialist copay, and based on your remaining deductible today's visit is estimated at $240. How would you like to take care of that?" Not "Would you like to pay anything today?"

  3. 3

    Offer the ways to pay Check-in

    Card, digital wallet, HSA card, text-to-pay link, payment plan, card on file with a capped auto-charge after adjudication. Every option has a script; the registrar picks, not the patient's silence.

  4. 4

    Pivot to help, not pressure When the answer is no

    "If the amount is a concern, we have a financial counselor who can check whether you qualify for assistance or set up a plan." The policy decides whether an elective service is rescheduled; the registrar never does it alone.

  5. 5

    Receipt, posting, reconciliation Same day

    Every payment gets a receipt with the account number and purpose (copay, deposit toward estimate), posts to the encounter, and balances to the cash drawer and the merchant report at close of day.

Card on file, done properly

Store card data only in the payment processor's vault (tokenization), with the patient's signed authorization that states the maximum amount, the trigger (after the plan adjudicates), and how to cancel. PCI DSS applies to any system that touches card numbers; registration screens should never hold them. Send the receipt and the explanation before charging.

Collections at the point of service are still collections

Nonprofit hospitals' financial assistance policies (501(r)) govern the whole encounter: the plain-language summary must be offered, and no extraordinary collection action may be taken before reasonable efforts to determine eligibility. Deferring or denying care because of a prior unpaid bill counts as an extraordinary collection action under the IRS rules unless the policy and notice requirements are met.

Measuring collections

POS cash collections (HFMA MAP Key PA-7)
Patient point-of-service payments ÷ total self-pay cash collected. The share collected before the patient leaves.
Pre-service collection rate
Dollars collected before the date of service ÷ dollars estimated for scheduled encounters. Tracks whether the pre-service call is turning estimates into payments.
Estimate accuracy
Adjudicated patient responsibility ÷ estimated patient responsibility, by service line. Within 10% is a common internal target; outliers point to bad fee mapping or stale accumulators.
Collection rate by registrar
Collected ÷ collectible for each registrar, used for coaching. Pair it with the ask rate (encounters where an amount was requested) so the measure rewards asking, not just lucky patient mixes.
Conversion rate of uninsured to a funding source (PA-6)
Uninsured patients converted to a third-party payer ÷ uninsured encounters. The financial counseling yield (chapter 09).
Chapter 09

Financial counseling, Medicaid screening and the clearance workflow

Financial clearance is a workflow, not a form. Scheduled encounters move through a queue of tasks that must finish before the patient arrives; uninsured and underinsured patients move through a second queue that looks for a payer or an assistance program. Both queues have owners, deadlines and a definition of "cleared."

The pre-service financial clearance workflow

  1. 1

    Encounter scheduled Day −10 or earlier

    The clearance record is created with the order, the service codes, the payer and the flags (auth, estimate, self-pay, Medicare notice review). Due date = date of service minus the clearance standard, commonly 2 to 3 business days.

  2. 2

    Eligibility and benefits verified Day −7 to −3

    271 run, other coverage searched, COB order set, accumulators captured, network status confirmed. Failed verification routes to a phone call to the patient the same day.

  3. 3

    Authorization and medical necessity Day −7 to −2

    Auth submitted and tracked (see the prior authorization tutorial); for Medicare, the diagnosis checked against the LCD and the ABN decision recorded.

  4. 4

    Estimate built and delivered Day −5 to −2

    Estimate from the calculator, GFE for self-pay patients within the statutory window, sent through the patient's preferred channel with a pay link.

  5. 5

    Financial counseling where needed Day −5 to −1

    Self-pay, high-balance, prior-balance and underinsured patients get a counselor call: assistance screening, Medicaid or marketplace application, payment plan, or a deposit agreement.

  6. 6

    Cleared, or escalated Day −2

    Status set to cleared when every task is done, or to "at risk" with a reason (no auth, no coverage, estimate unpaid) that the department and the scheduler can see. Elective services at risk are rescheduled under policy; emergencies and urgent care proceed regardless.

  7. 7

    Arrival Day 0

    Check-in becomes confirmation: identity, card, MSP, consents, ABN if flagged, payment. Walk-ins and ED patients run the same steps compressed, after screening.

Medicaid (expansion adults)Adults 19–64 with income up to 138% of the federal poverty level in expansion states: $22,025 for one person in 2026 (FPL $15,960 plus $5,680 per additional person)Screen every self-pay patient; file the application or refer to an enrollment vendor; request retroactive coverageFrom December 31, 2026 states must apply work or community engagement requirements (80 hours a month, with exemptions) and redetermine expansion adults every six months; retroactive coverage shrinks to one month from January 1, 2027
Medicaid (other groups) and CHIPChildren, pregnant women, parents, aged, blind and disabled, at state-specific income limitsSame screening; pregnancy and disability pathways often have higher limitsPresumptive eligibility lets qualified hospitals grant temporary Medicaid on the spot in many states

2026 Medicaid pressure

More churn, shorter lookback

The 2025 reconciliation law's Medicaid provisions mean more patients will lose coverage between visits and fewer months of retroactive coverage to recover. CBO projects about 10 million more uninsured people by 2034. Screening at every visit, not just at the first, becomes the norm.

Medicare Savings Programs

QMB, SLMB, QI

Low-income Medicare beneficiaries can have Medicaid pay their premiums and, for QMB, all cost sharing. Screening Medicare patients with large balances for MSP enrollment turns bad debt into crossover claims.

Payment plans

Interest-free, affordable, automatic

Offer a plan at the counter and on the statement: zero interest, a term tied to the balance, auto-pay, and a path to assistance if the patient cannot make the minimum. A plan that is set up is worth more than a deposit that is refused.

Counseling the underinsured

The patient with a $4,000 deductible in January is as much a counseling case as the uninsured patient. Experian's 2026 survey found fewer than two in five patients feel confident they can pay for care and 32% say paying got harder in the last year. The counselor's job is to show the number, explain where it comes from, check whether the hospital's assistance policy applies even to insured patients (many do, by income), and set up a plan the patient can keep. Document every conversation; the record is what proves "reasonable efforts" under 501(r) and what answers a complaint months later.

Clearance checklist

Chapter 10

Registration quality and the denials it causes

Registration quality is measured two ways: by auditing registrations against source documents before the claim, and by tracing denials back to the field that caused them after it. The first is cheaper. Together they tell you which registrars, which departments and which fields need attention.

Denials that start at registration

Auditing registrations

Sample

Daily, random, per registrar

Pull a random sample of yesterday's registrations per registrar (commonly 5 to 10) and compare each field to the scanned card, the ID, the 271 and the order. Score each field, not just the registration; a registration with one wrong digit in the member ID is 100% wrong for the claim but 95% right on the field count.

Weight

Not all fields are equal

Member ID, payer, subscriber, DOB and name break claims; email and emergency contact do not. Weight the scorecard so the accuracy rate reflects financial impact, and report the critical-field rate separately.

Target

98% or better on critical fields

A target of 98% accuracy on critical fields is common in access departments, with coaching below 95%. The number matters less than the trend by registrar and the specific fields that drive it.

Feedback

Same week, by name, with the fix

Errors fed back a month later as a percentage change nothing. The registrar needs the specific record, what was wrong, how to find it next time, and the denial it would have caused. Automated registration QA tools do this in real time at the desk.

Registration accuracy scorecardEnter an audit sample and the month's volume. The projections use your own assumptions for rework cost and claim value.

Fixing the process, not the registrar

Where most registration errors come from
  • Payer lists. Hundreds of plan entries with ambiguous names produce wrong-payer selections. Clean the list, name plans as the cards do, and map each to the right payer ID and billing rules.
  • Free-text fields. Member IDs keyed by hand instead of read from the scan. Require the scan and validate the ID format against the payer's pattern.
  • Search habits. "New patient" created without a proper search. Force a search with at least two traits before the button is enabled.
  • Interrupted check-in. Emergency department and bedside registrations done under time pressure. Finish them in a quality queue before the claim drops, not after.
  • No feedback loop. Billing works the denial and never tells access. Route every registration-caused denial back to the registrar with the record number.
  • Training. New registrars learn payers for months. Pair a 30-day audit of every registration with a mentor and a payer cheat-sheet; move to sampling only after the critical-field rate holds above target.

Rules and regulations

Patient access sits under more federal rules than any other part of the revenue cycle, because it is where the patient meets the provider. These are the ones that decide what a registrar may ask, must give, and may collect.

Federal · EMTALA

42 USC 1395dd; 42 CFR 489.24

Any patient who comes to a hospital emergency department must receive a medical screening examination and, if an emergency condition exists, stabilizing treatment or an appropriate transfer, regardless of ability to pay. Section 489.24(d)(4) forbids delaying the screening or treatment to inquire about insurance or payment, and forbids seeking prior authorization until screening is complete and stabilization has begun. Reasonable registration that does not delay care is permitted. Violations can end the hospital's Medicare agreement and bring civil monetary penalties.

Federal · No Surprises Act

Public Health Service Act 2799B-6 and 2799B-7; 45 CFR 149.610 and 149.620

Good faith estimates for uninsured and self-pay patients within 1 or 3 business days of scheduling (or on request), and the patient-provider dispute resolution process when a bill exceeds the estimate by $400 or more, started within 120 calendar days. Balance-billing protections for emergency services and for out-of-network care at in-network facilities limit what access may collect to the in-network cost sharing. The insured-patient GFE and advanced EOB await rulemaking; co-provider elements remain under enforcement discretion as of 2026.

Federal · Hospital price transparency

45 CFR Part 180; CY 2026 OPPS final rule (CMS-1834-FC)

Machine-readable standard charge files and a shoppable-services display or estimator. From January 1, 2026 (enforced from April 1, 2026): median, 10th and 90th percentile allowed amounts with counts, derived from remittance data; an accuracy and completeness attestation naming a senior official; Type 2 NPIs in the file. Penalties of $300 per day (30 or fewer beds) or $10 per bed per day up to $5,500 per day, with a 35% reduction for waiving the ALJ hearing. A February 2025 executive order directed stronger enforcement; 519 warning letters went out between April and early June 2026.

Federal · Transparency in Coverage

45 CFR 147.211; 26 CFR 54.9815-2715A; 29 CFR 2590.715-2715A

Non-grandfathered group and individual plans must post in-network negotiated rates and out-of-network allowed amounts (enforced since July 1, 2022) and provide a self-service cost estimator covering 500 items from plan years beginning in 2023 and all items from 2024. The prescription drug file remains under enforcement discretion. Access teams should expect patients to arrive with the plan's estimate and be able to reconcile it.

Federal · Medicare Secondary Payer

42 USC 1395y(b); 42 CFR Part 411; MSP Manual chapter 3

Medicare is secondary to group health plans of employers with 20 or more employees (working aged), large group health plans of 100 or more (disability), any group health plan during the 30-month ESRD coordination period, and to workers' compensation, no-fault, liability and Black Lung benefits. Providers must ask the MSP questions at every admission, encounter or start of care, re-verify every 90 days for recurring outpatients, and keep the answers 10 years. Billing Medicare primary when it is secondary is an overpayment subject to the 60-day return rule.

Federal · Medicare beneficiary notices

Social Security Act 1879 and 1866(a)(1)(Y); 42 CFR 405.1200–405.1206, 489.20(y); Claims Processing Manual chapter 30

Limitation on liability: a beneficiary is not liable for a service Medicare denies as not reasonable and necessary unless given a valid advance notice (ABN, CMS-R-131, revised 2026). The NOTICE Act requires the MOON within 36 hours of observation services for patients observed more than 24 hours. The IM is due within 2 days of admission and again within 2 days of discharge; the NOMNC at least 2 days before covered post-acute services end. Routine or blanket notices are not acceptable; notices are never required in emergencies.

Federal · QMB billing prohibition

Social Security Act 1902(n)(3)(B), 1905(p)(3), 1866(a)(1)(A)

Providers may not bill Qualified Medicare Beneficiaries for Medicare deductibles, coinsurance or copayments, must bill the state Medicaid program instead, and must refund any amounts collected and recall accounts sent to collections. QMB status appears in HETS eligibility responses and on the Medicare remittance. Violations breach the Medicare provider agreement and can bring sanctions.

Federal · HIPAA privacy and Patient Self-Determination Act

45 CFR 164.520, 164.530; 42 CFR 489.102

The notice of privacy practices must be given at the first service with a good-faith effort to obtain written acknowledgment, kept six years. Minimum-necessary rules apply to every eligibility inquiry and every conversation at the desk. Medicare providers must ask about advance directives and document the answer. Section 1557 of the ACA requires language assistance and accessible communication for patients with limited English proficiency or disabilities.

Federal · Section 501(r)

26 USC 501(r); 26 CFR 1.501(r)-1 to -7

Tax-exempt hospitals must maintain a written financial assistance policy and plain-language summary, limit charges to eligible patients to amounts generally billed, make reasonable efforts to determine eligibility before any extraordinary collection action, and wait at least 120 days after the first post-discharge statement. Deferring or denying care because of unpaid bills is an ECA. The policy applies at the point of service, not only in the business office.

Federal · Medicaid changes in the 2025 reconciliation law

Public Law 119-21, sections 71107, 71112, 71119, 71120

Expansion adults face work or community engagement requirements of 80 hours a month, effective no later than December 31, 2026 (states may be exempted until December 31, 2028), eligibility redeterminations every six months for renewals from December 31, 2026, retroactive coverage reduced to one month (two for other groups) from January 1, 2027, and cost sharing of up to $35 per service for incomes of 100 to 138% FPL from October 1, 2028. CBO projects about 10 million more uninsured people by 2034. Financial counseling volume will rise.

Federal · Interoperability (CMS-0057-F) and HIPAA transactions

45 CFR Part 162; CMS-0057-F

Payers must support the 270/271 eligibility and 278 authorization transactions and, from January 1, 2027, Patient Access, Provider Access, Payer-to-Payer and Prior Authorization FHIR APIs for Medicare Advantage, Medicaid, CHIP and federal-exchange plans. Coverage and claims data will increasingly be available inside the EHR at registration.

State law and accreditation

Hospital billing, estimate and collection statutes; Joint Commission NPSG.01.01.01

Many states add estimate rights for insured patients, interest and collection limits on medical debt, facility-fee disclosure, charity-care minimums and presumptive eligibility rules. Payment card handling is governed by the PCI Data Security Standard. Accreditation requires two patient identifiers before every service and documented processes for duplicate and overlay prevention.

What is changing

In effect 2026

New ABN and MOON forms, transparency enforcement

Revised CMS-R-131 mandatory from May 12, 2026 and the updated MOON from April 20, 2026. Hospital price files must carry allowed-amount percentiles and an executive attestation, and CMS is sending warning letters at scale.

Coming Dec 2026 – Jan 2027

Medicaid churn and FHIR APIs

Work requirements, six-month redeterminations and shorter retroactive coverage change financial counseling. CMS-0057-F Provider Access and Payer-to-Payer APIs go live January 1, 2027, bringing coverage data into the EHR.

Unresolved

Insured-patient estimates and the AEOB

The No Surprises Act's advanced EOB and the insured GFE still await rules, and the co-provider GFE element stays under enforcement discretion. Build the insured estimate anyway; patients and state laws expect it.
