Medicare Prescription Drug Coverage (Part D)

Prescription drug coverage is a voluntary benefit available to everyone with Medicare and is offered by private insurance companies approved by the federal government. Health insurers offer a variety of Part D plan options, with different covered prescriptions and costs. Prior to purchasing a plan, it is important to verify that your prescriptions are covered under the plan and what your financial responsibility will be. Important features about Part D monthly premiums and other plan costs are: 

  • Part D plans charge a monthly premium in addition to the Medicare Part B premium.
  • MA plans offering Part D coverage may include a charge for the prescription drug coverage in the monthly premium.
  • The amount you pay for Part D coverage may differ based on your income.
  • Part D plans may have yearly deductibles that must be met before the plan begins to pay its share of covered medications.
  • After the deductible has been met, the insured may be responsible for co-payments and co-insurance.

DIFS does not have authority over Medicare prescription drug plans; therefore, DIFS does not review or approve the contract language or the rates for MA plans. However, DIFS does license most of the health insurers that issue Medicare Part D plans in Michigan.
