Average costs for Alendronate with Medicare drug coverage

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

Deductible stage Typical copay stage
Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.

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 $480 in 2022.
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.
