The toll-free number for Member Services is shown on most of the information you received from your Medicare plan, such as plan enrollment or membership information, Summary of Benefits (SOB), Evidence of Coverage (EOC), monthly Explanation of Benefits (EOB) letter, and Annual Notice of Change (ANOC) letter.
We have the telephone number for most Member Services departments online, just click on the plan’s name or the "Benefits & Contact Info" button when using our Medicare Advantage Plan Finder or MA-Finder (enter your ZIP to begin) or our stand-alone Medicare Part D Plan Finder or PDP-Finder (choose your state to begin).

Both links will take you to a page showing more plan details such as formulary information (number of drugs per tier), cost-sharing, basic enrollment information, Star ratings, and the toll-free Member Services number for every Medicare Part D plan.

If you still cannot find the telephone number for your Medicare plan, please telephone Medicare at 1-800-633-4227, choose the option to speak with a Medicare representative and then ask the representative to provide the contact information for your Medicare Part D or Medicare Advantage plan. When you call, the Member Services representative can also provide you with your Medicare drug plan Membership information:
- Member ID,
- RxGroup ID,
- PCN,
- Rx BIN, etc.
