There is no single fund that pays medical bills in the United States. What exists instead is a scattered set of programs, most of them narrow, several of them nearly extinct, and a few that genuinely erase five-figure balances. Knowing which is which saves you from spending three weeks on a route that was never going to work.
Start with the one that pays out most often: the hospital’s own financial assistance policy. Nonprofit hospitals must have one to keep their tax exemption, the income limits are far higher than most people assume, and you can usually apply for months after the bill arrives. That process is covered in full in our guide to hospital charity care, and you should exhaust it before anything below. Everything on this page is what to do after that, or alongside it.
Step 1: Re-Check Your Coverage for the Dates of Service
Before hunting for charity money, make sure the bill is even yours to pay.
Retroactive Medicaid. Federal rules at 42 CFR 435.915 require a state to make Medicaid eligibility effective no later than the third month before the month you apply, as long as you got covered services during that window and would have qualified at the time. In plain terms, a bill from 90 days ago can still be paid by Medicaid if you apply now and qualify. This is the single most overlooked route for someone who lost a job or aged out of a parent’s plan mid-year. State variation matters: Florida ended the three-month retroactive period for adults 21 and older who are not pregnant, effective February 2019, and other states have sought similar waivers. Ask your state Medicaid office specifically about “retroactive eligibility” and name the dates of service.
Surprise billing protections. If the bill came from an out-of-network provider at an in-network facility, or from an emergency, federal law may cap what you owe. See the No Surprises Act before you negotiate a number you may not owe at all.
The itemized bill. Duplicate charges and coding errors are common enough that you should always request the itemized bill before applying for assistance based on the total.
Step 2: Check the Hill-Burton List
From 1946 onward, hospitals took federal construction money in exchange for an obligation to provide a set amount of free or below-cost care. Most obligations have expired, but HRSA still maintains a list of obligated facilities, and it runs to roughly 130 hospitals, clinics, nursing homes, and health centers nationwide as of September 2026.
If your facility is on that list, the terms are unusually good:
- Free care if your income is at or below the current HHS poverty guidelines.
- Reduced-cost care if your income is up to twice the guidelines, or three times for nursing home care.
- You can apply before or after you receive care, and HRSA states explicitly that you may apply even after a bill has been sent to a collection agency.
The odds that your specific hospital is on the list are low, which is why this step takes five minutes and not five hours. Search the HRSA obligated facilities list by state. If it is there, apply, because the eligibility floor is generous and the deadline is effectively open.
Step 3: Look for Sliding-Fee Care Going Forward
A federally funded health center charges on a sliding scale tied to household income, and many will also work with you on balances for care already delivered at that center. This does nothing for a hospital bill, but it stops the next bill from happening. If your problem is ongoing care rather than one event, moving your care to a health center is usually worth more over a year than any grant. Our guide to free clinics and sliding-scale care covers how to find one and what to bring.
Step 4: Apply to Disease-Specific Foundations
These are the funds with real money in them, and the crucial thing to understand is that most of them are designed for people who have insurance. They pay copays, coinsurance, deductibles, and premiums. They generally do not pay a self-pay hospital balance.
| Fund | What it covers | Key eligibility | Award |
|---|---|---|---|
| HealthWell Foundation | Copays, premiums, deductibles, out-of-pocket costs for supplies, supplements, and surgeries | Must have insurance that pays part of the cost, diagnosis must match an open disease fund, income within 300-500% of poverty depending on the fund | Varies by fund, 12-month grant cycle |
| Blood Cancer United (formerly the Leukemia & Lymphoma Society) | Copay assistance, plus non-medical costs: rent, mortgage, utilities, childcare, transportation, food | Blood cancer diagnosis, household income at or below 600% of poverty, in active treatment or surveillance | $500 Urgent Need and Local Financial Assistance grants, $100 Patient Aid stipend, $2,500 pre-CAR T travel grant, copay awards vary by fund |
| American Kidney Fund | Health insurance premiums through HIPP, plus Safety Net grants for transportation to dialysis, over-the-counter medicines, and copays | Kidney failure, receiving dialysis in the US or its territories, income-qualified | Grant amounts vary; AKF says it assists more than 70,000 people a year |
Two structural points. First, funds open and close as their money runs out, so check availability the day you apply rather than assuming last year’s fund still exists. Second, the PAN Foundation merged into Patient Advocate Foundation in March 2026 and its grants now run through the combined TotalAssist program, so old bookmarks will send you in circles. For drug-specific help, including manufacturer programs that give brand-name medicines away free, see prescription assistance programs.
Step 5: Call 211 and Work the Local Layer
Dial 211 from anywhere in the US and you reach a local information-and-referral line run by United Way affiliates and community agencies. They maintain the only reasonably current directory of what exists in your specific county: emergency utility and rent funds, township trustee assistance, county indigent care funds, hospital district programs, and church-based benevolence funds.
This layer is genuinely underrated because it is invisible from a search engine. A county indigent care fund does not have a marketing budget. Ask the 211 specialist directly about “medical bill assistance,” “township trustee,” and “county indigent care,” and ask whether your state has a catastrophic illness or hospital assessment fund. Some states do. Most do not, and they vary too much to summarize honestly.
Religious and fraternal organizations are the other real local source. Congregations, Knights of Columbus councils, Elks lodges, and similar groups often have small discretionary funds. They typically pay in the hundreds, not thousands, and they usually want to pay the provider directly rather than pay you.
Step 6: Understand What Crowdfunding Actually Returns
Medical crowdfunding is the most visible option and the weakest one. The numbers are not close.
The largest US study, published in the American Journal of Public Health, analyzed 437,596 American medical crowdfunding campaigns from 2016 to 2020. The median campaign raised $1,970 toward an $8,000 goal, from 24 donors. A 2025 American Cancer Society study of more than 78,000 cancer fundraisers from 2021 to early 2023 found a median $4,000 raised against a $10,000 goal, with only 11.5% of campaigns reaching their goal within 90 days. Take the two together and the realistic range for a median campaign is roughly $2,000 to $4,000, well under half of what people ask for.
The AJPH authors’ conclusion is worth quoting in spirit: crowdfunding is best positioned to help the populations that need it least, because returns track your existing social and economic network rather than your medical need.
Fees are the smaller problem. GoFundMe charges no platform fee to create a personal fundraiser in the US, and takes 2.9% plus $0.30 per donation for payment processing. On a $2,000 campaign that is roughly $70. Run one if you have a large, generous network and a story people can act on. Do not build a payment plan around it.
Step 7: Take the Tax Angle Seriously (Sometimes)
Two tax moves can return real cash on a bill you already paid.
The medical expense deduction. Per IRS Publication 502, you can deduct medical and dental expenses only if you itemize on Schedule A, and only the portion above 7.5% of your adjusted gross income. You can generally only count expenses you actually paid during the year. For most households the standard deduction wins and this is worth zero, but after a catastrophic year with a big out-of-pocket total it can matter.
HSA and FSA reimbursement. If you have a health savings account and paid a qualified expense out of pocket, you can take a tax-free distribution to reimburse yourself. Publication 502 is explicit that you cannot double dip: expenses paid with a tax-free HSA distribution cannot also be deducted, and neither can amounts fully reimbursed by an FSA. Note that the “paid this year” rule for the deduction is not the rule for FSA reimbursement, so check your plan’s own timing rules rather than assuming.
Step 8: Whatever Is Left, Negotiate
Assistance rarely covers the whole balance. What remains is a negotiation, and the leverage is real because a self-pay balance is worth a fraction of face value to a hospital. Work through how to negotiate medical bills, then set up a zero-interest payment plan rather than moving the balance to a credit card. If the debt is already old or in collections, check the statute of limitations and what medical debt can do to your credit report before you make a payment that restarts the clock. Some balances are also eligible for outright medical debt forgiveness.
The Bottom Line
In order of expected payoff: hospital charity care, then retroactive Medicaid for the dates of service, then Hill-Burton if your facility is on the list, then disease foundations if you have insurance and a matching diagnosis, then 211 and local funds, then negotiation on whatever is left. Crowdfunding and the tax deduction sit at the bottom because the median outcome for both is small. Use the fair price checker to confirm the bill is even in a defensible range before you go looking for money to pay it.
