Official Keytruda Copay Programs
Merck, the maker of Keytruda (pembrolizumab), runs the KEY+YOU Savings Card program. Eligible commercially insured patients pay $0 for up to 12 doses (about 6 months) per 12-month period, then as little as $5 per dose. No income check required, but excludes government insurance like Medicare/Medicaid. Apply online at keytruda.com or call 1-855-4KEYTRUDA.1
Merck also offers patient support through their Medical Information line (1-800-672-9374) for personalized copay navigation.1
Who Qualifies and How to Enroll
- Commercial insurance only: Medicare patients get no copay card but can explore Medicare Extra Help or state programs.
- No household income limits for the savings card.
- Enrollment: Instant activation via website or doctor's office; card works at most pharmacies. Coverage resets yearly.1
Underinsured patients may qualify for Merck's Patient Assistance Program, providing Keytruda free if income is ≤$100K single/$200K household and no other coverage. Submit forms via merckhelps.com.2
Medicare and Government Insurance Options
Medicare Part D covers Keytruda, but high costs hit the "donut hole." Use:
- Extra Help (LIS): Low-income subsidy reduces copays to $4-$10 per dose if income <135% federal poverty level.
- Medicare Savings Programs: State aid for premiums/copays.
- Patient Access Network (PAN) Foundation: Grants up to $10,300/year for copays if income ≤500% FPL. Apply at panfoundation.org.3
Keytruda's list price exceeds $11,000/month, so post-donut hole out-of-pocket can top $3,000 before catastrophic coverage kicks in.4
Independent Copay Foundations
Non-profit options for gaps in Merck programs:
- CancerCare Co-Payment Assistance Foundation: Up to $15,000/year for immunotherapy copays; income ≤400-500% FPL. cancercarecopay.org.5
- HealthWell Foundation: Covers copays/deductibles up to $15,000/year for cancer patients; income ≤500% FPL. healthwellfoundation.org.6
- Patient Advocate Foundation Co-Pay Relief: Up to $15,000/year; serves underinsured cancer patients. copays.org.7
These often prioritize high-need cases; apply early as funds deplete.
