Charity care eligibility: every nonprofit hospital is required to have a financial-assistance policy.

If a nonprofit hospital sent you a bill you can't pay, there's a federal law that may wipe out most or all of it — and almost nobody mentions it at the registration desk. Under the Affordable Care Act, every tax-exempt 501(c)(3) hospital in the country must keep a written Financial Assistance Policy (FAP), publicize it, and offer free or discounted care to patients who qualify. Most policies give 100% free care to households near the poverty line and sliding-scale discounts well into middle-income territory. Here's exactly who qualifies in 2026, what the income thresholds look like, and how to apply before a deadline costs you the discount.

The law behind it: ACA §501(r)

When Congress passed the Affordable Care Act in 2010, it added a new section to the tax code — Internal Revenue Code §501(r) — that attached real conditions to a hospital's tax exemption. The Treasury Department and IRS finalized the regulations in December 2014 (T.D. 9708), and they've been fully in force since tax years beginning after December 29, 2015. A nonprofit hospital that ignores them risks losing its 501(c)(3) status, which is the whole reason hospitals comply.

Section 501(r) imposes four core obligations on every tax-exempt hospital facility:

1. Maintain a written Financial Assistance Policy. It has to spell out the eligibility criteria, whether the assistance is free or discounted care, how the hospital calculates what it charges eligible patients, how a patient applies, and how the hospital decides. A plain-language summary is required too.
2. Widely publicize the policy. The hospital must post it on its website, make paper copies available free on request, and notify patients about it — including a conspicuous notice on billing statements with a phone number and web address. It must also be offered in the primary languages of the community.
3. Limit what eligible patients are charged. A FAP-eligible patient can't be billed more than the amounts generally billed (AGB) to patients who have insurance. No more chargemaster (full sticker) pricing for people who qualify for assistance.
4. Follow the rules before collections. The hospital cannot start "extraordinary collection actions" — selling the debt, reporting it to a credit agency, suing, garnishing wages, placing a lien — until it has made reasonable efforts to determine whether you qualify for financial assistance. That clock generally runs at least 120 days from the first post-discharge bill.

The IRS even built the FAP requirement into the hospital's annual return: Form 990, Schedule H asks tax-exempt hospitals to report their financial-assistance activity. This isn't a suggestion. It's a condition of being a nonprofit hospital.

Who is covered — and who isn't

Section 501(r) only binds tax-exempt 501(c)(3) hospitals. That's a big slice of the country: roughly 58% of US community hospitals are nonprofit, according to American Hospital Association figures. If you were treated at a nonprofit system — think the big regional names, Catholic health systems, university and academic medical centers, and most community hospitals — the federal FAP rules apply to you.

Two categories fall outside §501(r):

• For-profit hospitals (investor-owned chains) have no federal charity-care obligation under this law.
• Government hospitals (public, county, and many federal facilities) generally aren't subject to §501(r) either, though many run their own assistance programs and public hospitals often have the most generous ones.

Here's the catch that helps a lot of people: state law often fills the gap. Several states impose their own hospital charity-care or fair-pricing requirements that reach for-profit and public hospitals too:

• California — the Hospital Fair Pricing Act requires charity care or discount payment plans for patients up to 400% of the Federal Poverty Level, applying to most hospitals regardless of tax status.
• Washington — one of the strongest charity-care laws, mandating free care for lower incomes and sliding-scale discounts at higher ones, applicable broadly across hospital types.
• Illinois — the Fair Patient Billing Act and Hospital Uninsured Patient Discount Act set discount and collection rules.
• New York — the Hospital Financial Assistance Law requires sliding-scale discounts for eligible patients.

So even if your hospital isn't a nonprofit, check your state's rules before you assume you're out of luck. The bottom line: ask every time, no matter where you were treated.

The income thresholds: where you stand against the poverty line

Most FAPs anchor eligibility to the Federal Poverty Level (FPL), the income figures the Department of Health and Human Services publishes each year. The common pattern is:

• 100% free care for households at or below about 200% of FPL (some generous hospitals go to 250% or even 300%).
• Sliding-scale discounts for households between roughly 200% and 400% of FPL, with the discount shrinking as income rises.

The exact percentages vary hospital by hospital — that's why you have to read the specific FAP — but those bands are typical. To put real numbers on it, the 2025 HHS poverty guidelines (the ones in use through most of 2026) are about $15,650 for a single person and $32,150 for a family of four in the 48 contiguous states (Alaska and Hawaii are higher).

Run those through a typical policy and you get:

• Single person: 200% FPL ≈ $31,300 (likely full free care); 400% FPL ≈ $62,600 (likely a partial discount).
• Family of four: 200% FPL ≈ $64,300 (likely full free care); 400% FPL ≈ $128,600 (likely a partial discount).

That 400% line is the part people underestimate. A family of four earning over $120,000 a year often assumes they make far too much for "charity care" — and they may still qualify for a meaningful discount at many hospitals. The word "charity" is misleading; think of it as legally required price relief tied to income.

The AGB limit: you can't be charged the sticker price

This is the quiet, powerful piece of §501(r). Once you're approved for financial assistance, the hospital cannot bill you more than the amounts generally billed (AGB) to patients who have insurance for the same care. The full chargemaster rate — the inflated number on the first bill — is off the table for FAP-eligible patients by law.

Hospitals calculate AGB one of two ways:

• Look-back method. The hospital takes a year of past claims paid by Medicare fee-for-service and/or private insurers, divides what was actually allowed by the gross charges, and gets an AGB percentage. It applies that percentage to your bill. In practice this often drops the charge to roughly 35–65% of the sticker price, depending on the hospital's payer mix.
• Prospective method. The hospital uses what Medicare (or Medicaid) would pay for that service, as if you were a Medicare patient.

A hospital has to disclose which method it uses and the resulting percentage if you ask. The practical lesson: a FAP-eligible patient who pays anything close to the chargemaster price is being overcharged in violation of the rules.

Presumptive eligibility: sometimes you qualify automatically

You don't always have to fill out a full application. Many hospitals use presumptive eligibility — rules that auto-qualify certain patients based on circumstances that already signal low income. Common triggers include:

• Active enrollment in Medicaid (especially for services Medicaid doesn't cover).
• Enrollment in means-tested programs like SNAP (food stamps), WIC, or free/reduced school lunch.
• Homelessness or residence in low-income or subsidized housing.
• Being deceased with no known estate, or having a recent bankruptcy.
• A prior FAP approval at the same hospital within a set window.

Hospitals often use third-party data screening to flag presumptive-eligible accounts. If you fit one of these buckets, say so when you call — it can short-circuit the paperwork entirely.

How to apply, step by step

1. Ask for the FAP and the application. Call the hospital's billing or financial-assistance office and request the Financial Assistance Policy, the plain-language summary, and the application form. By law they must give these to you free of charge. The number and web address are required to appear on your billing statement.
2. Gather your documentation. Most applications ask for proof of income and household size: recent pay stubs, last year's tax return, W-2s, bank statements, and sometimes proof of any government benefits. Self-employed applicants may need a profit-and-loss statement. Keep copies of everything you submit.
3. Submit within the application window. Under §501(r), hospitals must accept and process FAP applications for at least 240 days after the first post-discharge billing statement. That's roughly eight months — a generous window, but don't sit on it.
4. Follow up in writing. After you submit, request written confirmation that the application was received and ask for a decision timeline. If you call, note the date, the name of the rep, and what they told you. Paper trails win disputes.
5. Appeal a denial. If you're denied or get less help than you expected, ask for the decision in writing and the reason. Many hospitals have an internal appeal process, and you can submit additional documentation (a job loss, a change in household size, medical hardship). Income borderline cases are often reversed with better paperwork.

Timing tactics that actually move the needle

• Apply even after the bill goes to collections. The 240-day application window keeps running even if the account was already turned over. If you apply and qualify, the hospital has to recall the account from extraordinary collection actions and reprocess the bill at the FAP rate.
• Request a hold while your application is pending. Ask the billing office (and any collection agency) in writing to pause collection activity until a decision is made. A pending FAP application is grounds for that pause under the reasonable-efforts rules.
• Apply retroactively to bills you already paid. Some hospitals will review accounts you've already paid within the window and refund the difference between what you paid and the FAP-eligible amount. It's not guaranteed everywhere, but it costs nothing to ask — and a refund of an overpayment is real money back.
• Reapply if your income drops. Lost a job or had hours cut after you were denied? That's a material change. Submit a fresh application with current documentation.

Common mistakes that leave money on the table

• Assuming you earn too much. The 400% FPL discount band reaches solidly middle-class households. A family of four over $120,000 can still qualify for a discount at many hospitals. Don't self-disqualify — let the hospital run the numbers.
• Never asking. Hospitals are required to publicize the policy, but front-desk staff rarely volunteer it during registration. Silence is the default. You have to raise your hand.
• Missing the deadline. The 240-day clock is generous but real. Letting a bill drift for the better part of a year without applying can cost you the discount entirely.
• Paying the chargemaster price. The first bill is usually the inflated sticker number. Paying it in full — especially if you'd qualify for FAP relief and the AGB cap — means overpaying for care the law says should cost you far less.
• Not keeping records. No copies of your application, no notes from phone calls, no written confirmations. When something goes sideways, the paper trail is what protects you.

How charity care stacks with your other moves

Financial assistance isn't an island. It pairs naturally with the other ways to cut a hospital bill. Before you pay anything, get an itemized bill and check it for errors — duplicate charges and coding mistakes are common, and they inflate the number a FAP discount would otherwise reduce. Our guide on how to negotiate a medical bill walks through the itemized-bill request, the error audit, and the negotiation scripts step by step; run that in parallel with a FAP application.

If the bill came from out-of-network emergency care or a surprise out-of-network provider at an in-network facility, you may also be protected by federal law from balance billing — see your No Surprises Act protections before you assume the charge is even valid. And to figure out what you should actually owe under your plan in the first place, run the numbers through our out-of-pocket cost calculator so you know your real deductible-and-coinsurance exposure before any discount is applied.

The order that usually works: confirm the bill is correct and not a surprise-billing violation, apply for financial assistance, and negotiate whatever remains. Each step lowers the base the next step works on.

Bottom line

Every 501(c)(3) nonprofit hospital in the country — about 58% of community hospitals — is legally required to have a written Financial Assistance Policy, to publicize it, to cap what eligible patients are charged at the amounts generally billed to insured patients, and to hold off on aggressive collections until it has checked whether you qualify. Many policies offer 100% free care up to around 200% of the Federal Poverty Level and sliding-scale discounts up to 400%, which reaches well into middle-income households. The application window runs about 240 days from your first bill, you can apply even after collections start, and some hospitals will refund overpayments. The single biggest mistake is never asking. If a nonprofit hospital billed you, request the FAP and the application today — in writing — before the clock runs out.
