Aetna – Important Member ID Card Changes for Those with Medicare Advantage Plans

The following changes begin on January 1, 2022:

• All Aetna Medicare Advantage plan members will have 12-digit member ID numbers beginning with “10.” They will no longer use the “ME” prefix for Medicare Advantage plans after that date. Consol Energy will transition from ID numbers beginning with “ME” to those beginning with “10” on April 1, 2022.

• “Group #” will be known as “Plan #.” Please use the plan number in the way that you have previously used the group number in your transactions.
