Medicare Coverage for Keytruda

Home » Resources » Medicare Coverage for Keytruda

Keytruda, also known by its generic name pembrolizumab, is a medication that belongs to a class of drugs called immune checkpoint inhibitors. It works by stimulating the body’s immune system to recognize and attack cancer cells. Keytruda has shown remarkable efficacy in treating various types of cancer, including melanoma, lung cancer, bladder cancer, and others.

Does Medicare Cover Keytruda?

One of the primary concerns for Medicare beneficiaries is whether Keytruda is covered by their Medicare plans. Medicare is a federal health insurance program in the United States that provides coverage for eligible individuals who are 65 years or older, as well as certain younger individuals with disabilities.

Medicare coverage for Keytruda depends on several factors, including the type of Medicare plan you have and the specific cancer diagnosis. Let’s take a closer look at the coverage options:

Original Medicare (Part A and Part B)

Original Medicare consists of Part A (hospital insurance) and Part B (medical insurance). Part A covers inpatient hospital care, while Part B covers outpatient services, including physician visits, diagnostic tests, and certain medications administered in a medical facility.

Keytruda, being an infused medication, is typically covered under Part B when administered in a hospital outpatient setting. However, it’s important to note that Part B only covers medications that are deemed medically necessary and approved by the U.S. Food and Drug Administration (FDA). Medicare will also consider whether Keytruda is supported by recognized medical guidelines and evidence-based research.

Medicare Advantage (Part C)

Medicare Advantage plans, also known as Part C, are offered by private insurance companies approved by Medicare. These plans provide the same coverage as Original Medicare (Part A and Part B) but may include additional benefits such as prescription drug coverage (Part D) and routine dental or vision care.

Coverage for Keytruda under Medicare Advantage plans can vary. Some plans may cover Keytruda as a Part B drug, while others may categorize it as a Part D prescription drug. It’s crucial to review the specific details of your Medicare Advantage plan to determine the coverage options for Keytruda.

Prescription Drug Coverage (Part D)

Medicare Part D provides prescription drug coverage for Medicare beneficiaries. Keytruda, when prescribed as a self-administered medication (in pill form), may be covered under Part D. However, the coverage specifics can vary depending on the specific Part D plan you have.

To determine if Keytruda is covered under your Part D plan, you should review the plan’s formulary (list of covered drugs) and check if Keytruda is included. It’s essential to note that Part D plans may have different tiers or cost-sharing structures, so understanding the details of your plan is crucial to estimate your out-of-pocket costs.

Appeals and Exceptions

In cases where Medicare denies coverage for Keytruda, beneficiaries have the right to appeal the decision. The appeals process allows you to request a review of the initial decision and present supporting documentation to demonstrate the medical necessity of Keytruda for your specific condition. It’s advisable to work closely with your healthcare provider and consult with a Medicare expert to navigate the appeals process successfully.


In conclusion, Medicare coverage for Keytruda can be complex and depends on various factors, including the type of Medicare plan and the specific cancer diagnosis. Understanding the coverage options under Original Medicare (Part A and Part B), Medicare Advantage (Part C), and Prescription Drug Coverage (Part D) is crucial for beneficiaries seeking treatment with Keytruda. If you have any questions or need further clarification, it’s recommended to reach out to Medicare directly or consult with a knowledgeable healthcare professional.
