Nonprofit hospitals receive $28 billion in annual tax exemptions — yet BillKarma’s analysis of 6,000+ hospital price transparency files finds that more than 1 in 3 hospitals with an F billing grade (charging over 8 times the Medicare rate) are nonprofits operating with federal tax-exempt status. The nonprofit label is a tax classification, not a promise of fair billing. Here’s what ownership type actually means for your bill — and what the law requires each type to give you.

1. The three hospital ownership types

Every hospital in the U.S. falls into one of three ownership categories. CMS tracks this for all ~6,000 registered hospitals, and it’s visible on every hospital’s profile in the BillKarma directory.

Type Also called Who owns it Pays taxes? Charity care required?
For-profit Proprietary Private investors, shareholders, or corporations Yes No federal requirement
Nonprofit Voluntary non-profit (private or church) Community boards, religious organizations, or nonprofit corporations No (tax-exempt) Yes, under IRS 501(r) & ACA
Government Public Federal, state, county, or local government No Yes, generally broader eligibility

Large for-profit chains include HCA Healthcare (the largest U.S. hospital operator), Tenet Health, and Community Health Systems. Major nonprofit systems include CommonSpirit Health, Ascension, Providence, and most academic medical centers. Government hospitals include VA hospitals, county safety-net hospitals, and university hospital systems.

Ownership type is a starting point, not a conclusion. Check our hospital directory to see the billing grade and average markup for any specific hospital — it’s the only way to know how that facility actually prices its care, regardless of who owns it.

2. Billing patterns by ownership type

Research consistently shows that for-profit hospitals carry higher average markups than nonprofits, and nonprofits carry higher markups than government hospitals. But the ranges within each category overlap heavily — a poorly run nonprofit can out-charge a well-run for-profit on specific procedures.

Ownership type Typical billing grade range Typical markup vs. Medicare Key pricing driver
For-profit C to F (most common) 4x–10x Medicare Shareholder return targets; aggressive chargemaster strategy
Nonprofit B to F (wide range) 2.5x–9x Medicare Varies widely by system size and market dominance
Government / public A to C (most common) 1.8x–4x Medicare Public funding supplements revenue; less reliance on chargemaster

According to Health Affairs research on hospital charge-to-cost ratios, for-profit hospitals have historically maintained higher ratios than nonprofits — but the gap has narrowed as large nonprofit systems have grown more dominant in regional markets. When one nonprofit system controls 60–80% of hospital beds in a metropolitan area, it faces the same reduced pricing pressure that for-profit chains experience in low-competition markets.

3. The nonprofit paradox: tax breaks vs. billing reality

The word “nonprofit” implies restraint. The billing reality often doesn’t match the expectation.

Nonprofit hospitals receive approximately $28 billion in annual federal, state, and local tax exemptions, according to a 2021 study in JAMA Internal Medicine. That exemption is supposed to be offset by community benefit — including charity care for patients who can’t pay. But the Lown Institute, which publishes an annual Fair Share analysis of nonprofit hospital finances, found that most large nonprofit hospital systems spend far less on charity care and community investment than the value of their tax exemptions.

BillKarma’s analysis of CMS price transparency data finds that more than 1 in 3 F-grade hospitals — those charging more than 8 times the Medicare rate — are tax-exempt nonprofits. That means when you look at the very worst billing actors in the U.S. hospital system, the majority are split between for-profits and nonprofits, not concentrated in either category. The nonprofit label does not prevent a hospital from:

  • Publishing a chargemaster with 8x+ Medicare markups (an F grade)
  • Billing uninsured patients at full chargemaster prices
  • Pursuing aggressive debt collection, including lawsuits and wage garnishment
  • Spending less than 1% of net revenue on charity care

The patient advocate point here is simple: do not assume a nonprofit hospital will treat you more fairly on billing. Check the grade. Check the charity care percentage. Check the financial assistance income thresholds. All of these are on each hospital’s BillKarma profile.

Don’t assume nonprofit means fair. Use our free calculator to look up what Medicare pays for your specific procedure — then compare it to your hospital’s gross charge regardless of whether it’s nonprofit or for-profit.

4. What nonprofit hospitals owe you (federal law)

Under IRS Section 501(r), any hospital claiming tax-exempt nonprofit status must meet four specific requirements. These are federal law, not optional policies:

  1. Written financial assistance policy (FAP). The hospital must have a written policy describing who qualifies for free or discounted care, how to apply, and what documentation is required. This must be posted on the hospital’s website and available in paper form on request.
  2. Limits on charges to FAP-eligible patients. A hospital cannot charge FAP-eligible patients more than the amounts generally billed (AGB) to insured patients — essentially the average negotiated rate. Billing FAP-eligible patients at full chargemaster rates violates 501(r).
  3. No extraordinary collection actions before FAP screening. The hospital must make “reasonable efforts” to determine whether a patient qualifies for financial assistance before sending their account to collections, filing a lawsuit, or garnishing wages.
  4. Emergency care without discrimination. The hospital cannot condition emergency care on ability to pay or require up-front payment in an emergency (this also applies under EMTALA to all hospitals, regardless of type).

If you received a bill from a nonprofit hospital at full chargemaster rates without being screened for financial assistance, or were referred to collections before your eligibility was assessed, those are potential 501(r) violations. Report them to the IRS using Form 13909 or contact your state attorney general’s office, which enforces nonprofit hospital compliance under state law. Income thresholds for charity care eligibility vary by hospital — check the FAP on the hospital’s website or its BillKarma profile before assuming you don’t qualify.

5. Government hospitals: the underrated option

Government hospitals — county hospitals, public hospital districts, state university hospitals, and VA medical centers — are consistently the lowest-markup hospital type in BillKarma’s data. Several reasons explain this:

  • No shareholder return requirement. Public hospitals aren’t optimizing for profit margin, which removes the main incentive for aggressive chargemaster inflation.
  • Public funding supplements revenue. Tax appropriations and public subsidies mean government hospitals are less dependent on chargemaster revenue to cover costs.
  • Safety-net mission. Most government hospitals serve high proportions of Medicaid and uninsured patients, which creates institutional culture around accessible pricing.
  • Broader charity care eligibility. Many county and public hospitals have financial assistance programs that cover patients up to 300–400% of the Federal Poverty Level, sometimes more.

If you’re uninsured or have a high deductible, a government/public hospital with an A or B billing grade is often the most cost-effective option for non-emergency care. Check availability in the BillKarma directory — filter by ownership type to see government hospitals near you.

6. How to use ownership type when comparing hospitals

Use ownership type as a first filter, then verify with the billing grade and procedure-level pricing.

Before a planned procedure:

  1. Search for hospitals in your area that can perform the procedure.
  2. Check the billing grade for each. If a government hospital is in your network and has an A or B grade, it’s your best starting point on price.
  3. For nonprofits, also check the charity care income threshold in case you need financial assistance.
  4. For for-profits, check procedure-level pricing — some for-profit hospitals price specific procedures competitively even if their overall grade is C or D.
  5. Cross-reference with the CMS Star Rating to balance cost and quality.

After you receive a bill:

  1. If you’re at a nonprofit hospital: immediately ask for the financial assistance policy and application. You may be eligible for free or reduced-cost care even if you weren’t screened at the time of service.
  2. If you’re at a for-profit hospital: ask specifically for the “self-pay discount” and “cash settlement” rates. Many for-profit systems offer 40–60% discounts off gross charges to cash-paying patients.
  3. If you’re at a government hospital: ask about sliding-scale payment programs and income-based waivers, which are often more generous than private hospital programs.
  4. Upload your itemized bill to BillKarma — ownership type changes what to ask for, but every bill can be checked for coding errors and markup anomalies regardless of who owns the facility.

7. Real examples

For-profit vs. government hospital: same colonoscopy, $1,200 difference

A patient in Phoenix needed a screening colonoscopy (CPT 45380, Medicare rate $198). She had a high-deductible plan with 20% coinsurance. Her closest hospital was a for-profit regional chain facility with a D billing grade — gross charge $1,840. The county hospital 12 miles away, a government facility with an A billing grade, listed the same CPT code at $412. Both were in-network. Her coinsurance at the for-profit facility: $368. At the county hospital: $82.

She scheduled at the county hospital. Total savings: $286 in direct coinsurance, plus $1,428 less applied to her deductible.

Large nonprofit system, F grade: charity care unlocked $3,200 in relief

A patient treated at a large regional nonprofit hospital (tax-exempt 501(c)(3), billing grade F, average markup 9.4x Medicare) received a $5,800 bill for an overnight observation stay. The patient’s household income was 210% of the Federal Poverty Level. The hospital’s financial assistance policy — which they had not been offered at discharge — covered patients up to 300% FPL at 100% discount.

After the patient requested the FAP application and submitted income documentation, the entire balance was written off. Total savings: $5,800 — available by law under 501(r), but never proactively offered.

Nonprofit vs. for-profit: same city, same procedure, different grades

A patient in Nashville needed an MRI of the knee (CPT 73721, Medicare rate $107). Two in-network hospitals were nearby: a for-profit facility with a C grade (4.3x markup, gross charge $460) and a nonprofit academic medical center with a B grade (2.8x, gross charge $300). The nonprofit, despite its tax-exempt status, was the cheaper option — illustrating that ownership type alone doesn’t determine price.

After insurance processed the claims, the patient’s 25% coinsurance was $115 at the for-profit and $75 at the nonprofit. Savings: $40 — and the academic center had a higher CMS Star Rating.

Frequently asked questions

Do nonprofit hospitals charge less than for-profit hospitals?

On average, yes — but the difference is smaller than most people expect, and it varies enormously by hospital. Many large nonprofit systems receive D or F billing grades. Always check the individual hospital’s billing grade in the BillKarma directory rather than assuming ownership type predicts what you’ll pay.

What do nonprofit hospitals owe patients?

Under IRS 501(r), nonprofit hospitals must have a written financial assistance policy, cap charges to FAP-eligible patients at the lowest negotiated rate (not gross charges), screen patients for financial assistance before pursuing collections, and make the FAP application available in paper form on request. These are federal requirements, not optional policies.

What is a for-profit hospital?

A for-profit hospital operates to generate returns for shareholders or private owners, pays corporate taxes, and has no federal charity care requirement. Major for-profit chains include HCA Healthcare, Tenet Health, and Community Health Systems. They can still offer financial assistance voluntarily — ask specifically for the “self-pay discount” and “cash settlement rate.”

Are government hospitals cheaper?

Generally yes. Government-owned hospitals (county, state, and public district hospitals) tend to carry lower average markups and more generous financial assistance programs than private hospitals of either type, according to BillKarma’s analysis of CMS price transparency data. They are consistently underutilized by patients who don’t realize they’re eligible for care there.

How do I find out who owns my hospital?

BillKarma’s hospital directory lists ownership type alongside the billing grade for every hospital. You can also check CMS Care Compare, which classifies every hospital as Proprietary, Voluntary non-profit, or Government.

Can a nonprofit hospital refuse to provide charity care?

A 501(c)(3) nonprofit hospital cannot deny emergency care based on ability to pay (also required under EMTALA for all hospitals) and must have a written charity care policy. If you were denied financial assistance screening before being sent to collections, that may be a 501(r) violation reportable to the IRS (Form 13909) or your state attorney general.
