Due to a processing error in January, some Medicare Advantage and Part D beneficiaries' requests to have premiums withheld from their Social Security benefit checks did not go through. As a result, those premiums have not been paid. Plans will be sending premium bills to those affected directly instead.
If you are affected and haven’t already received a bill in the mail, you will soon. The first bill will likely be for a larger amount than usual to make up for the unpaid premiums.
The plan may resubmit your request for Social Security withholding, but you will still need to pay any unpaid premiums. You can find additional information from Medicare in the premium withholding issue notice.
