Inflation Reduction Act improves drug coverage for Medicare patients


The Inflation Reduction Act of 2022 improves coverage and lowers out-of-pocket costs of recommended vaccines and insulin for people with Medicare plans.


  • Starting January 1, 2023, Medicare members with Part D drug coverage will pay nothing out-of-pocket for adult vaccines recommended by the Advisory Committee on Immunization Practices. These include the shingles and tetanus-diphtheria-pertussis (Tdap) vaccines.

Insulin/insulin products

  • Medicare members will have access to insulin for no more than $35 for a month’s supply. In addition, there will be no deductibles for covered insulin products.
  • The new rules for insulin coverage begin:
    • January 1, 2023, for insulin covered under Medicare Part D prescription drug plans
    • July 1, 2023, for insulin used through a traditional pump covered under Original Medicare’s durable medical equipment benefit
