2023 Part B Drugs Update

Important notice about changes to your Medicare Part B drug coverage
Because of changes to the Medicare program, there are new limits on how much you’ll pay for certain Part B drugs. These new rules will not increase your drug costs or change which drugs are covered. You don’t need to take any action. 

New rule to limit how fast your costs can go up for certain Part B drugs

• Beginning April 1, 2023, the amount you pay for Part B rebatable drugs will be reduced if the drug’s price has increased at a rate faster than the rate of inflation.
• The list of Part B rebatable drugs may change each quarter (in April 2023, July 2023, October 2023, and every 3 months after that). See the Part B rebatable drug list from CMS.
• The amount you pay for those drugs may change each quarter too — but you will never pay more than your Part B drug cost. 

New $35 cap on how much you’ll pay for Part B insulin

• Beginning July 1, 2023, you will pay no more than $35 for a 30-day supply of Medicare Part B-covered insulins (when you use insulin via a pump).
• If your Part B cost share amount is less than $35, you will pay the lower amount.
• Note that Part D insulins already have a $35 cap on how much you’ll pay for a 30-day supply of covered insulin. 

See your Evidence of Coverage (EOC) for details.
