Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in.

In the deductible stage, you’re responsible for the full cost of your prescription drugs.
Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $415 in 2019.
|After you meet your Part D deductible, you enter the initial coverage period.
During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.
