A large medical bill can look final, especially to an older patient on a fixed income. But at the nation’s tax-exempt nonprofit hospitals, that bill often is not final at all. Federal law requires those hospitals to run a financial assistance program, sometimes called charity care, that can slash or entirely erase a bill for a patient who qualifies. The catch is that the help is written into policy, not painted on the wall, and patients who never ask are the ones who pay in full.
The federal string attached to tax exemption
Nonprofit hospitals avoid a substantial tax bill in exchange for serving their communities, and the Affordable Care Act tied specific obligations to that status. Under Internal Revenue Code Section 501(r), a hospital that wants to keep its 501(c)(3) charitable exemption must meet a set of requirements aimed squarely at protecting patients from crushing bills. Financial assistance is not a courtesy at these institutions; it is a condition of the tax break they receive.
That distinction matters because it changes who holds the leverage. A patient asking a nonprofit hospital about charity care is not requesting a favor. They are invoking a program the hospital is legally obligated to maintain in order to stay tax-exempt.

What the written policy must contain
The rules are specific about the program itself. Section 501(r)(4) requires each hospital to adopt a written financial assistance policy that spells out who is eligible, whether the aid is free or discounted, how amounts charged are calculated, and exactly how a patient applies. The policy must cover all emergency and medically necessary care the hospital provides.
The same rule addresses the “rarely advertised” problem directly. Hospitals must make the policy, the application form, and a plain-language summary widely available: posted on a website, offered in paper form for free on request, and displayed in public areas including the emergency room and admissions. In practice, few patients notice those notices in the middle of a medical crisis, which is why the assistance so often goes unclaimed by people who would qualify.
Caps on charges and limits on collection
Two related provisions protect patients even further. Section 501(r)(5) limits what a hospital can charge a patient who is eligible for financial assistance for emergency or medically necessary care, generally holding it no higher than the amounts billed to insured patients rather than the inflated list price. That alone can turn an unaffordable bill into a manageable one for a qualifying patient.
Section 501(r)(6) governs what happens before a hospital can pursue payment. The IRS billing-and-collections rule bars a hospital from taking “extraordinary collection actions,” such as sending a bill to collections or reporting it to a credit bureau, until it has made reasonable efforts to determine whether the patient is eligible for assistance. A patient who applies for charity care generally cannot be handed to collections while that application is pending.
What “amounts generally billed” really means
The cap in Section 501(r)(5) hinges on a specific figure the hospital must calculate: amounts generally billed, or AGB. A patient found eligible for financial assistance cannot be charged more than AGB for emergency or medically necessary care, which ties the price to what insured patients effectively pay rather than the hospital’s full “chargemaster” list price. The gap between those two numbers is often large, and it is exactly the gap that swallows uninsured and self-pay patients who never apply.
Hospitals typically compute AGB with a “look-back” method, applying a percentage drawn from past Medicare and private-insurer claims to the gross charge, and the financial assistance policy must either state that percentage or explain how to obtain it for free. The rules also bar a hospital from rejecting an application over missing paperwork it never specifically required, so an applicant should not be deterred by an incomplete-looking form. Together these provisions mean a qualifying patient’s real exposure is a discounted, insurer-level rate, not the sticker number printed on the first statement.
How a patient actually claims it
The mechanics are straightforward once the program is on the table. A patient requests the hospital’s financial assistance policy and application, often from the billing or patient-financial-services office, and submits proof of income. Eligibility usually turns on household income measured against the federal poverty guidelines, with many hospitals offering free care below one threshold and sliding-scale discounts above it. Importantly, the IRS rules bar a hospital from denying assistance simply because a patient left out information the application did not specifically require.
Timing helps but is not always fatal to a claim. Hospitals must keep the application window open for a defined period after the first billing statement, and many will reconsider a bill already sent to collections if an application is filed within that window. A patient who has already paid part of a bill may still qualify for a refund of the overpayment under the hospital’s policy.
The practical lesson is that the burden is on the patient to ask. Nonprofit hospitals are required to build these programs, cap the charges, and pause collections, but they are not required to chase down every eligible patient and enroll them. For an older patient staring at a bill that seems impossible, the request for the financial assistance policy is the step that turns a legal protection into an actual reduction.
