Medicare Numbers Changing

The Centers for Medicare and Medicaid Services has begun transitioning to new Medicare Beneficiary numbers and moving away from using Medicare claim numbers as a way to identify participants. Medicare participants will receive a new Medicare card in the mail from the CMS. This CMS process may take up to a year to complete. If you participate in the State of Wisconsin Group Health Insurance Program and are on Medicare, you do not have to do anything -- we will update our system to reflect this Medicare number change.
