Uninsured? How to Access Hospital Charity Care and Appeal Medical Bills

Being uninsured when you need medical care can feel catastrophic — but it doesn't have to be. The US healthcare system has a little-known safety net specifically for uninsured and underinsured patients: charity care and financial assistance programs. These programs can reduce or entirely eliminate your medical bills, and in some cases, they're legally required.

This guide explains how charity care works, who qualifies, how to apply, and how to appeal if your request is denied.

What Is Charity Care?

Charity care is free or discounted medical care provided by hospitals to patients who cannot afford to pay. Most nonprofit hospitals in the US are required to provide charity care as a condition of their tax-exempt status under Section 501(c)(3) of the tax code.

In 2010, the ACA formalized this requirement: nonprofit hospitals must have a written Financial Assistance Policy (FAP) that:

• Describes eligibility criteria for free or discounted care
• States the basis for calculating amounts charged to eligible patients
• Describes how to apply for assistance
• Is widely publicized to patients and the community

Charity care programs vary significantly by hospital. Some hospitals provide free care to patients at up to 300–400% of the federal poverty level (FPL); others set the threshold lower. Many use a sliding scale for patients between income thresholds.

Who Qualifies for Charity Care?

Eligibility is primarily income-based. Common eligibility criteria:

• 100% free care: Income below 200% of the federal poverty level (approximately $30,000 for a single adult in 2025)
• Discounted care: Income between 200–400% FPL, with discount percentages sliding based on income
• Catastrophic bills: Some hospitals extend assistance to patients with higher incomes when medical bills represent a significant share of income (often >10–20% of annual income)

Some hospitals also consider:

• Total household income and assets
• Whether you qualify for public insurance but haven't enrolled
• Medical circumstances (emergency care, cancer treatment, etc.)

There is typically no citizenship or immigration status requirement for hospital charity care — nonprofit hospitals must serve all patients regardless of status.

How to Apply for Charity Care

Step 1 — Ask immediately. The best time to apply is before you receive care (if non-emergency) or as soon as possible after receiving emergency care. Tell the hospital financial counselor that you are uninsured and want to apply for financial assistance.

Step 2 — Get the Financial Assistance Application. Every nonprofit hospital must have one. You can typically download it from the hospital's website or request it from Patient Financial Services.

Step 3 — Gather income documentation. You'll typically need:

• Proof of income (pay stubs, tax returns, Social Security letters)
• Bank statements (some hospitals require these)
• Proof of household size
• Proof of any existing insurance (or a statement that you are uninsured)

Step 4 — Submit the application with documentation. Submit promptly — some hospitals have application windows (such as 240 days from the initial billing date, per ACA requirements).

Step 5 — Follow up. Processing takes 2–6 weeks typically. Follow up if you don't hear back.

If Your Charity Care Application Is Denied

Charity care denials are appealable. Common reasons for denial:

• Income documentation was incomplete
• Your income exceeded the hospital's threshold
• You were eligible for Medicaid but didn't enroll

How to appeal:

1. Request a written denial with the specific reason
2. If documentation was incomplete, gather and resubmit
3. If income just exceeds the threshold, explain any unusual expenses (other medical bills, housing instability, dependents)
4. Ask to speak with a patient financial advocate or social worker

Many hospitals have patient advocates on staff whose entire job is to help patients access financial assistance. Ask to be connected with them.

Medicaid Enrollment as an Alternative

If you're denied charity care because the hospital believes you qualify for Medicaid, the hospital may be right — and Medicaid is actually better for you than charity care, because it covers future care too. Contact your state Medicaid office or use healthcare.gov to check eligibility.

In some states, Medicaid can be applied retroactively to cover bills incurred up to 3 months before your application date (in states with retroactive coverage).

Negotiating with Hospitals Directly

Even if you don't qualify for formal charity care:

• Prompt-pay discounts: Many hospitals offer discounts of 10–40% for patients who pay a lump sum promptly
• Payment plans: Nonprofit hospitals cannot charge medical debt interest under IRS rules and must offer affordable payment plans
• Medical billing advocates: Third-party advocates review your bill for errors (studies show 80% of medical bills contain errors) and negotiate on your behalf, often for a percentage of savings

Stopping Collections

If your account goes to collections while a charity care application or appeal is pending:

• Federal law under the ACA requires nonprofit hospitals to suspend collection activities while a financial assistance application is pending
• Under the No Surprises Act, certain billing protections apply for emergency care
• Under state laws, additional protections may apply

If a hospital sends your bill to collections before your application is processed, file a complaint with the state Attorney General's office and the IRS (which oversees nonprofit hospital compliance).

State-Specific Programs

Many states have supplemental programs:

• Maryland: Maryland's Health Services Cost Review Commission regulates hospital charity care statewide
• New York: CDPHP and state programs supplement hospital charity care
• California: Various county health programs
