Premiums, copays and other Aetna Medicare costs

This page covers the different costs related to our plans. You’ll find answers to some common questions below.

It’s the amount you pay each month for your coverage.


Plan premiums will vary depending on what plan you’re in. Be sure you know your plan’s monthly premium.

It’s the amount you may have to pay out of pocket before your plan starts to pay its share of covered costs. Your deductible resets at the start of each plan year.


Comparing Medicare plans? Be sure to include the deductible, premium, copays and coinsurance in the yearly total cost.

It’s an amount you may have to pay out of pocket for covered services or prescription drugs.


  • A copay is a fixed dollar amount, such as $20 for a doctor visit.  
  • Coinsurance is a percent of the cost, such as 10% for a covered prescription drug. (To find out how much you’ll pay, multiply the percent times the cost. For example, if your coinsurance is 10% and a covered drug costs $100, you’ll pay $100 x .10, or $10.)

When choosing a plan, it’s important to know if your share of covered costs will be a copay or coinsurance.

IRMAA stands for Income-Related Monthly Adjustment Amount. It's an extra amount some people have to pay for their Medicare Part B and Part D coverage.


Here are some important points about the IRMAA:


  • You'll only have to pay an IRMAA if your income is above a certain amount.
  • If you have to pay an IRMAA, you’ll get a letter from the Social Security Administration (SSA).
  • If you don’t pay your IRMAA, you may lose your Part B or Part D coverage.
  • The SSA, not Aetna®, decides if you have to pay an IRMAA.
