Copay Cards vs Patient Assistance Programs: Which One Do You Need?

What Are Copay Cards and Patient Assistance Programs?

Both programs exist to reduce the cost of expensive prescription drugs. But they work very differently and serve different groups of patients. Getting this distinction right at the start saves you from applying to the wrong program — the most common mistake we see.

Copay cards (manufacturer savings cards)

A copay card is a discount funded by the drug manufacturer that reduces your out-of-pocket cost at the pharmacy. Your insurance pays its share first, and the copay card covers some or all of what you would normally owe.

• Who it's for: Patients with commercial (private) health insurance.
• How it works: The card is presented at the pharmacy alongside your insurance. It reduces your copay or coinsurance — often to $0–$25/month.
• Example: The Repatha copay card can reduce a drug that costs over $600/month to as little as $5/month for commercially insured patients (prices as of 2026).

Patient assistance programs (PAPs)

A patient assistance program (PAP) is a manufacturer-funded program that provides the drug for free or at very low cost to patients who cannot afford it — typically those who are uninsured, underinsured, or on a government insurance program like Medicare. Many patients are surprised to learn these programs exist, or that the income thresholds can be higher than expected.

• Who it's for: Uninsured patients, underinsured patients, and sometimes Medicare patients.
• How it works: You apply with proof of income and insurance status. If approved, the manufacturer ships the drug to you or your doctor — often at no cost.
• Example: Amgen's Patient Assistance Program provides Repatha at no cost to qualifying patients earning up to 600% of the federal poverty level (FPL) — roughly $93,000/year for a single-person household, higher for larger families (2026 thresholds).
• How you receive the drug: Unlike copay cards, PAP medications are often shipped directly to your doctor's office or a specialty pharmacy — not picked up at a retail pharmacy like CVS or Walgreens. Applications often require follow-up; expect to check status at least once after submitting.

Which Option Is Right for You?

Your insurance type determines your path. This is the single most important factor — get this right and everything else follows.

• You have commercial/employer insurance → Start with a copay card. Search for "[drug name] copay card" or find your drug on our drug directory.
• You have Medicare, Medicaid, or government insurance → You cannot use a copay card (federal law). Your path is a patient assistance program (PAP). Also look into Extra Help/LIS and the $2,000 annual cap.
• You are uninsured or underinsured → Apply for a PAP. Most manufacturers provide the drug at no cost if you meet income requirements.
• Not sure about your coverage? → Start with your drug's savings page on SaveRx — each one explains which programs apply and who qualifies.

Why These Programs Exist (and Why It's Confusing)

This isn't random. There are specific legal and economic rules behind each program — and understanding them means you can work with the system instead of against it.

Why manufacturers offer copay cards

Copay cards exist because high copays cause patients to abandon prescriptions. When a patient faces a $200 copay on a $600/month drug, many will decide not to fill it. The manufacturer covers your $200 copay to keep you on the drug — and continues receiving the $400+ from your insurance. This arrangement genuinely helps patients, but it only works when commercial insurance is paying the larger share on the back end.

Why copay cards cannot be used with Medicare

Federal anti-kickback law (42 U.S.C. § 1320a-7b) makes it illegal for drug manufacturers to offer copay subsidies to patients enrolled in government health programs — including Medicare Part D, Medicaid, CHIP, TRICARE, and VA benefits.

The reasoning: when the government is paying for the drug, it negotiates its own pricing terms. Allowing manufacturers to subsidize patient copays would incentivize prescribing of expensive brand-name drugs over cheaper alternatives — and would ultimately increase government spending. The law prevents this by banning the practice entirely.

This is not an individual manufacturer's policy. Every copay card for every drug has this restriction. It applies regardless of the drug, the manufacturer, or the amount of the subsidy. Our Medicare vs. commercial insurance guide explains how these restrictions shape what you pay under each insurance type.

Why patient assistance programs exist

PAPs serve a different purpose. They exist for patients who truly cannot access the drug through normal channels — people without insurance, people whose insurance doesn't cover the drug, and in some cases, Medicare patients who can't afford their out-of-pocket costs even with coverage.

Because PAPs provide the drug directly (not through insurance), they don't trigger the same anti-kickback concerns. They are structured as charitable giving programs with income-based eligibility. Patient assistance applications often require income documentation and can take longer than copay card enrollment — but the payoff is significant: the drug is usually provided at no cost.

Real-World Examples

Common Mistakes That Cost Patients Money

These mistakes cost patients hundreds or thousands of dollars per year. Each one is avoidable once you know what to watch for.

• Applying for the wrong program first.
  This is the most common time-waster. If you have commercial insurance, start with a copay card — don't spend weeks on a PAP application. If you have Medicare or no insurance, skip the copay card entirely and go straight to a PAP. The decision framework above can help you pick the right path in seconds.
• Assuming you don't qualify for anything.
  Many patients never even look into savings programs because they assume the discounts are "for someone else." In reality, copay cards have no income requirement — anyone with commercial insurance is likely eligible. And PAP income limits are often surprisingly high (up to $94,000/year for some programs). If you're paying more than $25/month for a brand-name drug, check.
• Trying to use a copay card with Medicare.
  This is the single most common confusion. Federal law prohibits it — period. If you have Medicare and try to use a copay card, the pharmacy will reject it. Don't waste time. Go straight to your drug's Patient Assistance Program or look into Medicare Extra Help.
• Not completing the PAP application fully.
  PAP applications require your doctor's signature, proof of income, and sometimes proof of insurance status. Incomplete applications are the most common reason for delays or denials. Gather all documents before you start, and follow up within a week of submission.
• Giving up after the first rejection.
  PAP denials happen — especially if documentation was incomplete or income was slightly above the threshold. You can almost always reapply with additional documentation. Some programs also offer appeal processes. A denial is not necessarily final.
• Not asking your doctor's office or pharmacy for help.
  Many cardiology, oncology, and specialty offices have staff whose job is helping patients with savings programs and prior authorizations. Specialty pharmacies often have financial counselors too. You don't have to figure this out alone — ask.
• Forgetting to renew annually.
  Both copay cards and PAP approvals expire — usually annually. If you miss renewal, you'll be charged full price on your next fill with no warning. Set a calendar reminder 30–60 days before expiration.
• Confusing copay cards with GoodRx coupons.
  They are not the same thing. A copay card works with your insurance to reduce your share. A GoodRx coupon bypasses insurance entirely and gives you a negotiated cash price. They serve different purposes, and one may be dramatically better than the other depending on your drug and plan. For a deeper explanation, see our guide on how copay cards work.

What You Should Do Next

PAP application checklist

If the PAP route applies to you, gather these documents before starting the application — missing paperwork is the most common cause of delays:

• Completed application form (from manufacturer website or your doctor's office)
• Proof of income: most recent tax return, two recent pay stubs, or Social Security award letter
• Proof of insurance status — or an insurance denial/non-coverage letter
• Your doctor's signature and NPI number (your doctor's office will know this)
• Your current prescription details (drug name, dose, prescribing physician)

1. Identify your insurance type

   Look at your insurance card. Is it a commercial/employer plan? Medicare? Medicaid? No insurance at all? This single fact determines which program you need.

2. Choose your path

   Commercial insurance → copay card. Medicare/government → PAP + Medicare Extra Help. No insurance → PAP + independent foundations.

3. Find your drug's specific savings page

   Each drug has its own enrollment process, eligibility rules, and savings amounts. Start with the drug-specific page — it will walk you through exactly what to do. Browse our full drug directory or start with one of the links below.

4. Apply — and follow through

   For copay cards, enrollment is usually online in under 10 minutes. For PAPs, gather your documents first (income proof, insurance status, doctor's info), then submit the application. Follow up within a week if you don't get confirmation — incomplete paperwork is the number-one cause of delays.
