Keytruda is a prescription medication used to treat several types of cancer, including melanoma, lung cancer, head and neck cancer, and Hodgkin lymphoma. As of August 2021, Keytruda is protected by patents that will expire in 2028 [1]. Keytruda is a biologic medication, which means it is made from living cells and is more complex than traditional medications.

The cost of Keytruda can be high, but there are financial assistance programs available to help eligible patients. Merck, the manufacturer of Keytruda, offers a patient assistance program called Key+You. This program provides financial assistance to eligible patients who are uninsured, underinsured, or facing other financial hardships [2].

In addition to the Key+You program, Medicare may cover the cost of Keytruda for eligible patients. Medicare Part B may cover Keytruda if it is medically necessary and administered in a doctor's office or outpatient clinic [3]. However, coverage may vary depending on the specific plan and the patient's individual circumstances.

It is important to note that insurance coverage for Keytruda may vary depending on the specific insurance plan and the patient's individual circumstances. Patients should check with their insurance provider to determine their coverage options and eligibility for financial assistance programs.
