IRS Section 501(r) is the federal tax law that forces every nonprofit hospital in the United States to run a financial assistance program. If you were treated at one, you have six specific rights: the hospital must have a written financial assistance policy and hand it to you for free, it cannot charge you more than insured patients pay once you qualify, it must give you at least 240 days from your first bill to apply, it cannot send you to collections or report you to credit bureaus during the first 120 days, it must refund anything you overpaid, and it cannot demand payment before treating an emergency. These rules apply whether or not the hospital tells you about them, and they apply retroactively to bills you already received.
Roughly 3 in 5 community hospitals in the country are nonprofit, which means 501(r) covers most hospital care in America. What it does not do is set a national income limit. Each hospital writes its own eligibility rules, and that is where most people get lost.
What Section 501(r) Actually Requires
Section 501(r) was added by the Affordable Care Act in 2010, with final IRS regulations taking effect in 2016. A nonprofit hospital that ignores it can lose its tax exemption. Four requirements sit at the core.
| Code Section | Requirement | What it means for you |
|---|
| 501(r)(3) | Community Health Needs Assessment | Hospital must study local health needs every 3 years. Failure triggers a $50,000 excise tax per facility. |
| 501(r)(4) | Written financial assistance policy (FAP) and emergency care policy | The hospital must have a published, publicized policy and cannot discourage you from seeking emergency care. |
| 501(r)(5) | Limitation on charges | Once you qualify, you cannot be billed more than "amounts generally billed" to insured patients. Gross chargemaster prices are banned. |
| 501(r)(6) | Billing and collections | The hospital must make "reasonable efforts" to determine if you qualify before taking aggressive collection action. |
The requirement most patients never hear about is 501(r)(6). It is the one that stops a hospital from suing you or wrecking your credit while you still had time to apply.
Right 1: The Policy Must Be Easy to Get, in Your Language
The hospital has to widely publicize its FAP. Specifically it must:
- Post the full FAP, the application form, and a plain language summary on its website, downloadable free and without special software
- Give you a free paper copy on request, including by mail, and offer copies in the emergency department and at admission
- Include a plain language summary with billing statements
- Tell you about the policy in phone conversations about your balance
- Translate the FAP, application, and summary into any language spoken by an LEP group making up the lesser of 1,000 people or 5% of the community it serves
The FAP itself must spell out eligibility criteria, whether the assistance is free or discounted, how charges get calculated, how to apply, what the hospital does about nonpayment, and which outside providers practicing at the hospital are covered by the policy.
That last item matters more than people expect. The anesthesiologist, radiologist, or ER physician group that billed you separately may or may not be on the hospital's provider list. If they are not, the hospital's financial assistance does not erase their bill and you need to ask that group about its own discount policy.
Right 2: A Hard Cap on What You Can Be Charged
Once a hospital determines you are FAP-eligible, Section 501(r)(5) caps your bill at "amounts generally billed," or AGB, for emergency and medically necessary care. AGB is roughly what an insurance company would have paid, not the sticker price.
Hospitals pick one of two methods to calculate it:
| Method | How it works | Typical effect |
|---|
| Look-back | Hospital divides what insurers actually allowed on claims over a prior 12-month period by the associated gross charges, producing an AGB percentage it applies to your bill | Often lands somewhere around 25% to 45% of gross charges, varying widely by hospital |
| Prospective Medicare or Medicaid | Hospital bills you what Medicare (or Medicaid) plus the beneficiary would have paid for that same care | Usually a steep reduction from chargemaster prices |
For all other care covered by the FAP, the hospital must charge less than gross charges. The chargemaster price, the inflated number on the itemized bill, is off the table for anyone who qualifies for assistance.
Ask the billing office two questions: which AGB method do you use, and what is your current AGB percentage. Both are supposed to be available free of charge, and the plain language summary must state that a FAP-eligible person cannot be charged more than AGB.
Right 3: You Get at Least 240 Days to Apply
This is the single most useful thing to know. The clock runs from the date of your first post-discharge billing statement, not from the date of service.
| Day | What happens |
|---|
| 0 | First billing statement after discharge. Both clocks start. |
| 0 to 120 | Notification period. No extraordinary collection actions allowed. Hospital must include a plain language FAP summary with statements and mention the policy in calls about your balance. |
| At least 30 days before day 120 | Hospital must send written notice naming the specific collection actions it may take and the deadline. |
| 0 to 240 | Application period. You can submit a financial assistance application at any point. |
| Day 240 | Last day the hospital is required to accept an application under federal rules. Many hospitals voluntarily accept them later. |
You can apply after the bill has gone to a collection agency. You can apply after you have already made payments. You can apply after a lawsuit is filed. Filing inside the 240-day window forces the hospital to stop collection activity, decide your application, and tell you the outcome in writing.
If your application is incomplete, the hospital cannot simply reject it. It must tell you what is missing and give you a reasonable chance to supply it.
Right 4: Protection From Extraordinary Collection Actions
Extraordinary collection actions, or ECAs, are the aggressive moves. Under the regulations, they include:
- Selling your debt to a third party
- Reporting you to consumer credit reporting agencies
- Deferring or denying medically necessary care, or requiring payment first, because of an unpaid bill from prior care
- Any legal or judicial process: liens on your home, foreclosure, bank account seizure, a civil lawsuit, wage garnishment, or a body attachment order
A hospital cannot start any of these until it makes "reasonable efforts" to determine whether you qualify for its FAP. That means the 120-day quiet period, the required notices, and the 30-day advance written warning. Two things are carved out and are not ECAs: filing a claim in your bankruptcy proceeding, and asserting a lien on proceeds from a personal injury settlement.
Right 5: Refunds and Reversal
If you are later found FAP-eligible, the hospital must refund any amount you paid above what you actually owed under the policy, unless the excess is under $5. That includes payments you made to a debt buyer.
It also has to take all reasonably available measures to unwind any ECA already taken against you. That means vacating a judgment, lifting a lien, releasing a garnishment, and asking the credit bureaus to delete the adverse reporting.
People routinely leave this money behind because they assume a paid bill is a closed bill. It is not, as long as you are inside the application window.
Right 6: Emergency Care Without a Payment Demand
Section 501(r)(4) also requires a written emergency medical care policy providing nondiscriminatory emergency treatment regardless of FAP eligibility. The policy must prohibit anything that discourages you from seeking emergency care, including demanding payment up front in the emergency department or running debt collection activity in the ED.
If a registration desk tells you to settle an old balance before you are seen for an emergency, that is a 501(r) problem on top of an EMTALA problem.
What 501(r) Does Not Give You
Being clear about the limits saves you time:
- No federal income limit. The hospital picks its own thresholds. 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 to 300% or 400% FPL. Some are far more generous, some far less. Around 19 states impose their own legal minimums that also reach for-profit hospitals. See our state-by-state charity care breakdown.
- No coverage of for-profit or government hospitals. 501(r) is a tax-exemption condition. A for-profit hospital has no federal obligation, though many run voluntary policies and some states mandate one.
- No private right to sue. You cannot take a hospital to federal court for a 501(r) violation. Enforcement runs through the IRS and, in many states, the attorney general.
- No automatic enrollment. Some hospitals use presumptive eligibility, screening you based on Medicaid denial letters, homelessness, or public assistance enrollment. Most still require an application.
How to Apply, Step by Step
- Find the FAP. Search "[hospital name] financial assistance policy" or look for "billing and financial assistance" on the hospital site. Download the FAP, the application, and the plain language summary. Call and request paper copies if the site is unhelpful.
- Check the income threshold and the measurement period. Some hospitals use the last 3 months of income annualized, some use last year's tax return. If your income dropped recently, use the method that reflects your current situation and say so in writing.
- Gather documentation. Typically a photo ID, recent pay stubs or a benefits award letter, last year's tax return, and recent bank statements. Some hospitals count assets, most do not count a primary home or one vehicle.
- Apply for Medicaid at the same time. Many hospitals require you to apply for Medicaid first, and a denial letter is often the fastest route to approval. If your state expanded Medicaid, coverage runs to 138% FPL, and Medicaid can pay retroactively for up to 3 months of past bills in many states. Our comparison of charity care versus Medicaid covers how they interact.
- Submit and get a receipt. Send by a trackable method. Email or fax with confirmation beats mail. Note the submission date.
- Tell the collection agency in writing. If the account is already with a collector, send a copy of the submitted application. A pending complete application obligates the hospital to suspend ECAs.
- Get the decision in writing. The hospital must notify you in writing of the eligibility determination and the basis for it.
What to Do When a Hospital Breaks the Rules
If a hospital refuses to give you the policy, charges a FAP-eligible patient full chargemaster rates, sues inside the 120-day notification period, or ignores an application filed inside 240 days:
- File IRS Form 13909, the Tax-Exempt Organization Complaint (Referral). Email it to eoclass@irs.gov or mail it to IRS TEGE Classification, Mail Code 4910DAL, 1100 Commerce Street, Dallas, TX 75242-1027. Include dates, dollar amounts, names, and copies of the notices you received. You can request anonymity.
- Contact your state attorney general. Several states, including Washington, New York, Maryland, and Illinois, have brought enforcement actions and recovered refunds for patients. State charity care laws often carry teeth that 501(r) does not.
- Read the hospital's Form 990 Schedule H. Nonprofit hospitals report charity care spending and their FAP income thresholds there. It is public on ProPublica's Nonprofit Explorer and it is useful leverage when a billing office claims you do not qualify.
2026 Policy Context
Two shifts changed the medical debt landscape going into 2026. The CFPB rule finalized in January 2025 that would have stripped medical debt from consumer credit reports was vacated by a federal court in July 2025, and in October 2025 the CFPB issued an interpretive rule stating that the Fair Credit Reporting Act preempts state laws restricting medical debt credit reporting. That litigation is ongoing and state-level protections remain contested.
What did not change: the three major credit bureaus' voluntary policy of excluding paid medical collections and medical collections under $500, and the 501(r) rule that a hospital must reverse adverse credit reporting once it finds you FAP-eligible. That reversal right is now more valuable than it was two years ago, because the federal backstop that would have removed the reporting automatically is gone.
At the state level, legislatures moved in both directions in 2026. Delaware lawmakers introduced a bill to broadly expand charity care eligibility after reporting on narrow hospital policies, while Oregon hospitals pushed to raise the bill threshold that triggers mandatory financial assistance screening from $500 to $1,500 per encounter. Check your state's current rules rather than assuming last year's applied.
Frequently Asked Questions
Does 501(r) apply if I have insurance?
Yes. Financial assistance policies cover insured patients too. Deductibles, coinsurance, and out-of-pocket maximums can leave an insured patient with a bill that qualifies. Nothing in 501(r) limits the FAP to the uninsured, though individual hospitals set their own income criteria.
Can I apply after my bill went to collections?
Yes. The 240-day application period runs from your first post-discharge billing statement regardless of where the account sits. A hospital that receives a complete application must suspend collection activity while it decides. Many hospitals accept applications well past 240 days as a matter of policy.
Will the hospital refund payments I already made?
If you are found FAP-eligible and you paid more than you owed under the policy, yes. The hospital must refund the excess unless it is under $5, including money you paid to a debt buyer.
What is the difference between charity care and a payment plan?
Charity care reduces or erases the amount owed. A payment plan just spreads the same balance over time. Hospitals often steer patients toward payment plans because it preserves revenue. Ask specifically for the financial assistance application, using that phrase.
Do doctor bills get covered by the hospital's policy?
Only if that provider appears on the hospital's FAP provider list, which the hospital is required to publish. Physician groups that bill separately and are not on the list have their own policies. Request each one individually.
Does applying hurt my credit or immigration status?
No. A financial assistance application is not a credit application and does not generate a hard inquiry. Hospital charity care is not a federal public benefit and is not counted in the public charge test. Hospitals may ask for income documentation but cannot condition emergency care on it.
What if the hospital is for-profit?
Section 501(r) does not apply. Check your state law, since several states mandate financial assistance from all licensed hospitals, and ask for the hospital's own financial assistance or "uncompensated care" policy, which most large systems maintain voluntarily.
