By the VerifyDoc team
If you received care at a nonprofit hospital and can't afford the bill, federal law — specifically IRS Section 501(r) and its implementing regulations at 26 CFR §§ 1.501(r)-1 through 1.501(r)-7 — requires that hospital to offer you a financial assistance program, and bars it from aggressive collection tactics until it has genuinely tried to find out whether you qualify.
This post explains exactly what the 501(r) rules guarantee, how to find out if you're eligible, what "Amounts Generally Billed" means and why it caps how much a qualifying patient can ever owe, and what steps you can take if a nonprofit hospital ignores its own obligations. We also cover how state rules can go further than the federal floor, and the specific billing-error patterns to watch for on a bill you've already received.

The Affordable Care Act added Section 501(r) to the Internal Revenue Code, attaching specific community-benefit strings to the federal tax exemption that nonprofit hospitals receive. Hospital organizations must meet the requirements imposed by Section 501(r) on a facility-by-facility basis in order to be treated as an organization described in Section 501(c)(3). In plain terms: a hospital that ignores 501(r) risks losing its tax-exempt status entirely.
The four core requirements are: a Community Health Needs Assessment under Section 501(r)(3); a Financial Assistance Policy and Emergency Medical Care Policy under Section 501(r)(4); Limitation on Charges under Section 501(r)(5); and Billing and Collections rules under Section 501(r)(6). The two most important for patients reviewing a bill are 501(r)(4) — what the FAP must contain and how it must be publicized — and 501(r)(6), which governs what collectors can and cannot do before eligibility is determined.
Roughly 58% of U.S. community hospitals are nonprofit 501(c)(3) organizations, and in exchange for their federal tax exemption, the IRS requires them to publish and apply a Financial Assistance Policy (FAP) under 26 CFR § 1.501(r)-4. That means the majority of hospitals you're likely to visit are bound by these rules.
2. What the Financial Assistance Policy Must Contain
Section 501(r)(4) requires a hospital organization to establish a written FAP for each hospital facility it operates. The FAP must apply to all emergency and other medically necessary care provided by that facility, including care provided by a substantially-related entity within the hospital. That last clause matters: contracted physicians who treat you inside the hospital walls may be covered by the same policy.
Under 26 CFR § 1.501(r)-4(b), the FAP must spell out eligibility criteria, the basis for calculating amounts charged to patients, and the method for applying. Either the FAP or the FAP application form must describe the information and documentation the hospital may require as part of a patient's application, along with contact information for assistance. A hospital facility may not deny financial assistance based on an applicant's failure to provide information or documentation unless that information or documentation is specifically described in the FAP or application form.
The hospital must also provide a "plain language summary of the FAP" — a written statement that briefly describes eligibility requirements and assistance offered, summarizes how to apply, provides the direct website address and physical locations where patients can get the FAP, and gives instructions on how to receive a free copy by mail. If you've never seen this summary, the hospital may be violating 26 CFR § 1.501(r)-4(b)(5)'s wide-publicization requirement. You can request it directly from the billing department.
Hospitals must also accommodate all significant populations with limited English proficiency by translating FAP documents into the primary language spoken by these populations. That duty is threshold-bound: it applies to each language group that is the lesser of 1,000 individuals or 5% of the community the hospital serves, so a language below that threshold does not trigger it.
3. Income Limits and the AGB Cap: What You Can Actually Be Charged
One of the most common misconceptions is that financial assistance is only for people in poverty. Federal law does not set an income limit — each hospital picks its own. The IRS sets a floor on the process and the billing cap, not on who qualifies.
In practice, most nonprofit hospitals give fully free care at or below 200% of the Federal Poverty Level — which is $31,920 for one person and $66,000 for a family of four in 2026 — with sliding-scale discounts running up to 300% or 400% FPL. Some state laws push that even higher: Illinois runs to 600% FPL at non-rural hospitals, and California runs to 400%.
Even if you earn above a hospital's free-care threshold, Section 501(r)(5) caps what you can be charged. A hospital organization meets the requirements of Section 501(r)(5) only if it limits the amount charged for care to any FAP-eligible individual to, in the case of emergency or other medically necessary care, not more than the Amounts Generally Billed (AGB) to individuals who have insurance covering such care.
AGB is defined at 26 CFR § 1.501(r)-1(b)(1) and calculated under § 1.501(r)-5(b). AGB means the amounts generally billed for emergency or other medically necessary care to individuals who have insurance covering such care, determined in accordance with § 1.501(r)-5(b). Using the look-back method, a hospital facility calculates its AGB percentage as a fraction of gross charges — historically well below the chargemaster rates you see on a hospital bill. If you're FAP-eligible and were billed at full chargemaster rates, that's a billing error you can dispute.
4. Key 501(r) Terms: A Glossary for Bill Reviewers
Hospital bills are cluttered with terminology that obscures what you're actually owed. The table below defines the terms most relevant to patients reviewing a nonprofit hospital bill under 501(r).
| Term | What It Means in Plain English | Relevant CFR Section |
|---|---|---|
| FAP (Financial Assistance Policy) | The hospital's written policy on who qualifies for free or reduced-cost care and how to apply. Every nonprofit hospital must have one. | 26 CFR § 1.501(r)-4(b) |
| FAP-Eligible | You qualify for assistance under the FAP whether or not you've applied yet. Eligibility is separate from having submitted an application. | 26 CFR § 1.501(r)-1(b)(15) |
| AGB (Amounts Generally Billed) | The legal maximum a nonprofit hospital can charge a FAP-eligible patient — roughly what it accepts from insured patients, not the chargemaster rack rate. | 26 CFR § 1.501(r)-5(b) |
| Gross Charges | The hospital's full chargemaster price — what appears on your initial itemized bill before any adjustments. FAP-eligible patients legally cannot be charged this amount for emergency or medically necessary care. | 26 CFR § 1.501(r)-1(b)(16) |
| ECA (Extraordinary Collection Action) | Aggressive debt-collection steps — lawsuits, wage garnishment, liens, credit reporting — that are prohibited until the hospital makes reasonable efforts to determine FAP eligibility. | 26 CFR § 1.501(r)-6(b) |
| Application Period | The 240-day window from your first post-discharge billing statement during which you can submit a FAP application and the hospital must accept it. | 26 CFR § 1.501(r)-1(b)(3) |
| Plain Language Summary | A required, easy-to-read overview of the FAP that the hospital must offer you at intake or discharge and send with its written notice before any ECA. | 26 CFR § 1.501(r)-1(b)(24) |
If you've been reading your hospital bill and not recognizing these terms, that's a sign to ask for the FAP explicitly. The right phrase to use when calling is: "I'd like to request your Financial Assistance Policy application and plain language summary." The hospital is legally required to provide it.
5. The 240-Day Window and Collection Protections Under 501(r)(6)
Section 501(r)(6) requires a hospital organization to make reasonable efforts to determine whether an individual is eligible for assistance under its FAP before engaging in Extraordinary Collection Actions (ECAs) against that individual. This is one of the most consequential patient protections in the law — and one of the most commonly violated.
A hospital facility is held accountable for the ECAs of third parties collecting debt on its behalf or to which it sells debt. That means if the hospital sold your account to a collection agency and that agency sued you before your FAP eligibility was determined, the hospital may be in violation of 501(r)(6) — not just the collector.
The application window runs 240 days from the first post-discharge billing statement. Reasonable efforts include waiting at least 120 days after the first post-discharge bill before starting any ECA, plus a written notice at least 30 days before the first ECA. The hospital must also include the easy-to-understand FAP summary with that notice, and make a reasonable effort to orally notify the patient about the policy and how to get help applying.
If a hospital defers or denies medically necessary care, or requires payment before providing care, because of nonpayment of a previous bill, those actions also constitute extraordinary collection actions. Requiring deposits can be tantamount to denying care for medically indigent people. Requiring payment before providing medically necessary care because of nonpayment of past bills is therefore itself an ECA with respect to those past bills. If a hospital ever told you it wouldn't treat you until you paid an old balance, that may be a 501(r)(6) violation worth reporting to the IRS.

6. How to Identify 501(r) Billing Errors on a Bill You've Already Received
Getting a bill that looks wrong is exactly the situation 501(r) was designed to address. The following patterns on a nonprofit hospital bill are worth flagging and disputing.
Pattern 1 — Charged at gross (chargemaster) rates despite being FAP-eligible. If your income was at or below the hospital's FAP threshold and your bill reflects full chargemaster prices rather than AGB-based rates, the hospital may have charged you more than 26 CFR § 1.501(r)-5 permits. Request a copy of the hospital's AGB percentage and compare it to what you were actually charged. For a detailed walkthrough on reading every line, see our guide on how to read your itemized hospital bill in 2026.
Pattern 2 — No FAP notice on billing statements. Under 26 CFR § 1.501(r)-4(b)(5), the hospital must widely publicize its FAP, which includes including FAP information on billing statements. If you received a bill with no mention of financial assistance, the hospital may not be meeting its publicization obligation.
Pattern 3 — Collection action taken too early, or not suspended once you applied. Two different clocks run from your first post-discharge billing statement, and they are easy to confuse. Under § 1.501(r)-6(c) the hospital must refrain from Extraordinary Collection Actions for 120 days and give you at least 30 days' written notice first — so an ECA begun on, say, day 150 is generally lawful, not a violation. The 240-day figure is different: it is how long the hospital must accept and process a FAP application. If you apply within those 240 days, the hospital must suspend any ECA already under way and process your application. So the questions to ask are whether an ECA started inside the first 120 days, whether you got the 30-day notice, and whether anything you filed inside 240 days was refused or ignored.
Pattern 4 — Separate physician bills excluded from FAP. Emergency physicians, radiologists, anesthesiologists, and pathologists often bill separately and are not automatically covered by the hospital's FAP. This is a common gap. You may need to apply for financial assistance separately with each physician group. Ask each one whether they have their own FAP or participate in the hospital's policy. A related billing error to watch for is upcoding — read our post on how hospitals inflate bills through upcoding and how to spot it.
Pattern 5 — Already paid and then found eligible. If you apply within the 240-day application period and qualify, federal rules require a refund of anything you paid above your FAP-eligible amount; several states, including Oregon, also require refunds for patients later found eligible. If you already paid, apply anyway and ask for a refund. Outside that window a refund depends on state law or hospital policy, but it is worth pursuing everywhere.
7. State Laws That Go Further Than the Federal Floor
Section 501(r) is a federal minimum. Many states have layered additional requirements on top of it — and some states apply those requirements to for-profit hospitals as well.
A minority of states — California, Washington, Illinois and New Jersey among them — require all licensed hospitals to offer financial assistance regardless of tax status. That means even a for-profit hospital in those states must have a FAP, even though federal law would not otherwise require it.
Washington's attorney general has actively enforced its charity care law and recovered refunds for patients. State enforcement varies significantly, so knowing your state's rules can make a real difference in what leverage you have when disputing a bill.
If you're in a state with stronger rules, apply under state law as well as the federal 501(r) process. You're not limited to one or the other, and state law may give you a more generous income threshold or a longer application window. California, for example, prohibits application deadlines entirely.
The Tax Exempt Hospital Transparency Act (H.R. 9504), approved by the House Ways and Means Committee on 1 July 2026 by 25 votes to 15, would expand Form 990 reporting for nonprofit hospitals — including disclosure of the number of financial assistance applications received, granted, and denied under each hospital's FAP under IRS Code Section 501(r)(4) — signals growing federal interest in whether hospitals are actually delivering on their financial assistance obligations. If enacted, that data would become publicly available and useful for comparing hospitals in your area.

How do I find out if my hospital has a Financial Assistance Policy under 501(r)?
Every nonprofit 501(c)(3) hospital is required under 26 CFR § 1.501(r)-4(b)(5) to widely publicize its FAP — including posting it on its website and making it available in the billing office. Call the hospital's billing department and ask specifically for the "Financial Assistance Policy" and the "plain language summary of the FAP." If the hospital's website has a patient services or billing section, the FAP application is often available there as a downloadable PDF. If the hospital refuses to provide it or claims it doesn't exist, you can file a complaint with the IRS, since noncompliance with 501(r) threatens the hospital's tax-exempt status. You can also check the hospital's Form 990 (publicly available on ProPublica's Nonprofit Explorer) for a description of its FAP.
What documents does the hospital typically require when I apply for financial assistance?
Requirements vary by hospital, but the FAP or FAP application form is required under 26 CFR § 1.501(r)-4 to list every document the hospital may request — and the hospital cannot deny you based on a document that isn't listed there. Common requests include recent federal tax returns, pay stubs or employer letters, bank statements, and proof of household size. Critically, under 26 CFR § 1.501(r)-4(b), the hospital may grant assistance even if you can't provide every document — it can rely on other evidence or an attestation from you. If you're unhoused, unemployed, or lack documentation, tell the financial assistance office: many hospitals have presumptive FAP-eligibility procedures that allow approval based on third-party data or a signed statement.
A collection agency is calling me about a hospital bill. Is the hospital violating 501(r)?
It depends on timing. Under 26 CFR § 1.501(r)-6, a nonprofit hospital — and any collector acting on its behalf — must make "reasonable efforts" to determine FAP eligibility before taking Extraordinary Collection Actions (ECAs). Reasonable efforts include waiting at least 120 days after your first post-discharge bill before any ECA, giving you written notice at least 30 days before the first ECA, and giving you a full 240-day window from that bill to apply. If those steps weren't followed, the hospital may be in violation. Under IRS rules, the hospital is accountable for the ECAs of third parties to whom it sells the debt. Document every contact you've received, note the dates, and compare them to the date of your first billing statement. You can report potential violations to the IRS Tax Exempt and Government Entities Division.
I already paid my hospital bill in full. Can I still apply for financial assistance?
Yes — and you should, especially if your income would have qualified you. If you apply within the 240-day application period and are found eligible, federal rules require the hospital to refund anything you paid above your FAP-eligible amount (unless the excess is under $5). Some states also require refunds — Oregon, for example, requires hospitals to refund patients later found FAP-eligible. After that window, many hospitals will still apply a retroactive FAP discount as a goodwill measure if you apply promptly. There's no cost to applying, and the worst outcome is that the hospital declines. Also check whether any ECA, such as credit reporting, started within 120 days of your first post-discharge bill or without 30 days' written notice — if it did, you may have grounds to dispute both the underlying charge and any negative credit reporting resulting from it.
