340B Drug Pricing: Hospitals Get Huge Discounts. Do You?
A federal program requires drug makers to sell medications to qualifying hospitals at 25-50% off. The intent was to help low-income patients get affordable prescriptions. Instead, hospitals pocket the savings and charge you full price. This is the story of the 340B Drug Pricing Program, why it rarely benefits patients, and what you can do about it.
What Is the 340B Drug Pricing Program?
In 1992, Congress created the 340B Drug Pricing Program as part of the Public Health Service Act. The idea was straightforward: drug manufacturers that wanted their products covered by Medicaid had to sell outpatient drugs at steep discounts to hospitals and clinics that served a disproportionate share of low-income patients. The intent was to “stretch scarce federal resources as far as possible, reaching more eligible patients and providing more comprehensive services.”
The discounts are substantial. Depending on the drug, 340B entities pay 25% to 50% less than the Average Manufacturer Price (AMP). For some specialty medications and drugs with large Medicaid rebates, the discount can exceed 50%. Generic drugs often carry smaller discounts, while brand-name and specialty drugs can see dramatic price reductions.
How 340B Has Grown
- 2005: Approximately $4.4 billion in annual 340B drug purchases
- 2010: The Affordable Care Act expanded 340B eligibility to include critical access hospitals, sole community hospitals, rural referral centers, and freestanding cancer hospitals
- 2020: Over $29 billion in 340B drug purchases (nearly 7x growth in 15 years)
- 2024: Program exceeds $53 billion. One in three U.S. hospitals now participates
The program now covers more than 50,000 individual contract pharmacy arrangements and over 12,000 covered entity sites. What started as a modest program for safety-net providers has become one of the largest drug purchasing programs in the country, second only to Medicaid.
The Problem: Hospitals Keep the Spread
Here is how the 340B math works in practice. A hospital buys a cancer drug for $50 at the 340B price. It administers that drug to a patient and bills the insurer $500 (the standard list price). The hospital pockets the $450 difference. The patient, if they owe a percentage coinsurance, pays based on the $500 charge, not the $50 acquisition cost.
The 340B Spread in Real Numbers
This is not an edge case. It is the standard model. There is no federal requirement for 340B hospitals to pass any of these drug savings on to patients. The statute is silent on the matter, and HRSA (the agency that oversees the program) has never imposed such a requirement.
What the Research Shows
Government Accountability Office (GAO), 2011: Found that 340B hospitals had higher average outpatient drug revenue per patient than non-340B hospitals, suggesting they were billing at standard rates while acquiring drugs at discount.
USC Schaeffer Center, 2021: Analysis of 4,600 hospitals found that 340B hospitals were more likely to charge commercially insured patients higher prices for outpatient drugs than non-340B hospitals. The study concluded that “340B savings are not consistently benefiting patients.”
Johns Hopkins, 2022: Found that 340B hospitals provided roughly the same level of charity care as non-340B hospitals after controlling for size and patient mix, raising questions about where the 340B revenue actually goes.
New England Journal of Medicine, 2023: Researchers found that 340B hospitals did not provide significantly more uncompensated care than non-340B hospitals. The growth in the program was driven primarily by hospital acquisitions of physician practices and expansion of outpatient sites, not increased care for vulnerable populations.
The uninsured patient paradox
Studies show that 340B hospitals charge uninsured patients the same or more than non-340B hospitals for outpatient drugs. The program was designed to help exactly these patients, but without any requirement to pass savings through, the patients who need help most often see no benefit at all.
The Exception: Community Health Centers
Federally Qualified Health Centers (FQHCs) are the one bright spot in the 340B story. Unlike hospitals, FQHCs are required by law to serve patients regardless of ability to pay, using a sliding fee scale based on income. When an FQHC participates in 340B, the savings genuinely help reduce costs for low-income patients. This is what the 340B program was supposed to look like everywhere.

Which Entities Qualify as 340B Covered Entities?
Not every hospital or clinic can participate in 340B. The program is limited to specific categories of healthcare providers that serve vulnerable populations. Here are the main types of 340B covered entities:
Hospital Types
- Disproportionate Share Hospitals (DSH): Hospitals that treat a high percentage of Medicaid and low-income patients. This is the largest category of 340B hospital participants.
- Children’s hospitals: Freestanding children’s hospitals exempt from the Medicare prospective payment system
- Cancer hospitals: Freestanding cancer hospitals exempt from PPS
- Critical access hospitals: Small rural hospitals (added by the ACA in 2010)
- Sole community hospitals and rural referral centers (added by the ACA in 2010)
Community and Specialty Clinics
- Federally Qualified Health Centers (FQHCs): Community health centers serving underserved populations on a sliding fee scale. The entities most likely to pass 340B savings to patients.
- Ryan White HIV/AIDS clinics: Clinics funded through the Ryan White CARE Act for HIV/AIDS treatment
- Hemophilia treatment centers: Federally funded treatment centers for hemophilia patients
- STD clinics, TB clinics, and Black Lung clinics: Public health clinics receiving specific federal grants
- FQHC Look-Alikes: Organizations that meet FQHC requirements but do not receive federal Health Center Program grants
In total, over 12,000 covered entity sites participate in the 340B program. This number has grown dramatically since the ACA expanded eligibility in 2010, and continues to grow as hospitals acquire physician practices and register them as 340B child sites.
How Patients CAN Actually Benefit from 340B
Despite the systemic problems, there are real ways for patients to tap into 340B savings. It requires knowing where to look and what to ask.
1. Fill prescriptions at 340B contract pharmacies
Some 340B hospitals and clinics operate their own in-house pharmacies that dispense 340B-priced drugs directly to patients. If you are a patient at a qualifying hospital, ask if they have an on-site pharmacy and whether you can fill your outpatient prescriptions there at a reduced cost.
These pharmacies are often located inside or adjacent to the hospital. Prices will vary, but uninsured and underinsured patients may receive significant discounts compared to a standard retail pharmacy.
2. Ask directly for the 340B discount
This sounds simple, but most patients never think to ask. If you are uninsured or underinsured and receiving care at a 340B hospital, ask the pharmacy or billing department directly: “Does this hospital participate in the 340B program? Can I get my prescriptions at the 340B price?”
The hospital is not required to say yes. But many will, especially for patients who can demonstrate financial need. You have more leverage than you think, particularly at nonprofit hospitals that need to justify their tax-exempt status.
3. Use Federally Qualified Health Centers (FQHCs)
FQHCs are the gold standard for patient-facing 340B savings. Unlike hospitals, FQHCs are required by their federal grant conditions to serve all patients regardless of ability to pay, using a sliding fee scale based on income. If your income is below 200% of the Federal Poverty Level, you may pay little or nothing for prescriptions at an FQHC pharmacy.
There are over 1,400 FQHCs operating more than 15,000 sites across the country. You do not need to be uninsured to use one.
4. Check your state’s 340B requirements
A handful of states have passed or are considering laws that require 340B entities to direct savings toward patient care. Oregon, for example, requires hospitals to report how they use 340B revenue and directs savings toward charity care and community benefit. Other states, including Minnesota and Washington, have increased transparency requirements. Check whether your state has specific 340B reporting or patient-benefit mandates.

The Contract Pharmacy Controversy
One of the most contentious issues in 340B today is the role of contract pharmacies. Originally, 340B entities were expected to dispense drugs through their own in-house pharmacies. But HRSA guidance in 2010 allowed covered entities to contract with an unlimited number of outside retail pharmacies (CVS, Walgreens, independent pharmacies) to dispense 340B drugs on their behalf.
This opened the floodgates. Today, a single 340B hospital can have contract pharmacy arrangements with hundreds of retail locations spread across an entire state, or even nationwide. The covered entity buys the drug at the 340B price, the contract pharmacy dispenses it, and the entity bills the patient’s insurer at the full rate. The entity and the contract pharmacy split the revenue.
Drug Manufacturers Push Back
Starting in 2020, major drug manufacturers began refusing to provide 340B discounts on drugs dispensed through contract pharmacies. The companies that have imposed restrictions include:
- Eli Lilly (first to restrict, July 2020)
- AstraZeneca (August 2020)
- Sanofi (September 2020)
- Novo Nordisk (October 2020)
- United Therapeutics, Novartis, and others followed in 2021 and 2022
These companies argue that contract pharmacies have turned 340B into a profit engine for large hospital systems and pharmacy benefit managers, with little evidence that savings reach patients. They point to cases where major health systems with billions in annual revenue operate hundreds of contract pharmacy arrangements while spending a declining share of revenue on charity care.
HRSA and the Courts Respond
HRSA declared the manufacturer restrictions illegal and issued violation letters. But enforcement has been inconsistent, and multiple federal lawsuits are working through the courts. In 2022, the Supreme Court ruled in American Hospital Association v. Becerra that HHS had improperly cut Medicare reimbursement rates for 340B hospitals, handing a partial victory to the hospital industry. The broader question of whether manufacturers can restrict contract pharmacy access remains unresolved.
What this means for patients
The contract pharmacy fight is primarily a dispute between hospitals and drug companies over billions of dollars. For patients, the practical impact is this: if a drug manufacturer has restricted 340B pricing at contract pharmacies, you may need to fill your prescription at the hospital’s own in-house pharmacy to benefit from the 340B price (if the hospital offers that option at all). Retail contract pharmacies may no longer have access to the discounted price for certain drugs.
How to Find 340B Covered Entities Near You
HRSA maintains a public database called the Office of Pharmacy Affairs Information System (OPAIS) that lists every registered 340B covered entity in the country. You can search by name, city, state, or entity type.
Steps to Search the HRSA 340B Database
- 1Go to 340bopais.hrsa.gov (the HRSA OPAIS database)
- 2Click “Search” or “Covered Entity Search”
- 3Enter your state, city, or the name of a specific hospital or clinic
- 4Filter by entity type. If you want the best chance of getting patient-facing savings, filter for Federally Qualified Health Centers (FQHCs)
- 5Call the entity and ask: “Do you have a 340B pharmacy? Do uninsured or underinsured patients receive the 340B price?”
Being listed as a 340B entity does not mean you will get a discount
The OPAIS database tells you which organizations buy drugs at 340B prices. It does not guarantee that those organizations will pass any discount to you. Always call ahead and ask specifically about pricing for uninsured or underinsured patients. FQHCs are your best bet for actual patient-facing savings.

What is the 340B Drug Pricing Program?
The 340B Drug Pricing Program is a federal program created in 1992 that requires pharmaceutical manufacturers to sell outpatient drugs at significant discounts (typically 25-50% off) to eligible healthcare organizations that serve low-income and uninsured patients. These organizations include disproportionate share hospitals, federally qualified health centers, children’s hospitals, and Ryan White HIV/AIDS clinics. The program has grown to over $53 billion in annual drug purchases.
Do 340B hospitals pass drug discounts to patients?
In most cases, no. There is no federal requirement for 340B hospitals to pass drug discounts on to patients. Studies from the GAO, USC Schaeffer Center, and Johns Hopkins have found that 340B hospitals often charge patients and insurers the same prices as non-340B hospitals, keeping the difference as revenue. The major exception is Federally Qualified Health Centers (FQHCs), which are required to serve patients on a sliding fee scale regardless of ability to pay.
How do I find a 340B pharmacy near me?
Search the HRSA Office of Pharmacy Affairs Information System (OPAIS) database at 340bopais.hrsa.gov to find 340B covered entities in your area. Look specifically for Federally Qualified Health Centers (FQHCs), which are the most likely to pass savings to patients. You can also call hospitals directly and ask if they operate a 340B pharmacy and whether uninsured or underinsured patients receive discounted drug pricing.
Can insured patients use 340B pharmacies?
Yes. You do not need to be uninsured to fill prescriptions at a 340B pharmacy. However, the savings primarily benefit the 340B entity rather than the patient when insurance is involved. The hospital buys the drug at the 340B price and bills your insurer the standard rate. For uninsured or underinsured patients, some 340B entities (especially FQHCs) offer reduced pricing directly. Always ask whether the entity passes 340B savings to patients.
What is a 340B contract pharmacy?
A 340B contract pharmacy is a retail pharmacy (such as CVS, Walgreens, or a local independent pharmacy) that has an agreement with a 340B covered entity to dispense 340B-priced drugs on the entity’s behalf. This allows 340B organizations to extend their reach without operating their own pharmacy. However, contract pharmacies have become controversial, with several drug manufacturers restricting 340B pricing at contract pharmacy locations since 2020.
Why are drug companies fighting the 340B program?
Major drug manufacturers argue the 340B program has expanded far beyond its original intent, with large hospital systems using it to generate revenue rather than help low-income patients. Since 2020, companies like Eli Lilly, AstraZeneca, Sanofi, and Novo Nordisk have restricted 340B pricing at contract pharmacies. HRSA has pushed back with enforcement actions, and multiple lawsuits are ongoing. The Supreme Court ruled in 2022 that HHS had improperly cut 340B reimbursement rates in Medicare.
Does 340B affect my insurance premiums?
Yes. When hospitals bill insurers full price for drugs they bought at a 340B discount, those inflated charges contribute to higher healthcare spending across the system. This ultimately gets passed along to consumers in the form of higher premiums, higher deductibles, and higher coinsurance rates. The 340B spread is one of many factors driving up the cost of employer-sponsored and marketplace health insurance.
Is 340B the same as financial assistance or charity care?
No. The 340B program gives hospitals discounted drug prices, but it does not require them to discount your bill. Financial assistance (charity care) is a separate obligation under IRS Section 501(r) for nonprofit hospitals. However, if your hospital is a 340B entity, it is almost certainly a nonprofit, which means it must offer a financial assistance policy. You should inquire about both 340B pricing and financial assistance when facing high drug costs at a hospital.
