Medicare Eligibility

If you and/or your spouse are new enrollees to Medicare Parts A and B, and you wish to enroll in a Medicare Advantage plan, you must attach a copy of your and/or your spouse’s Medicare card to the Retiree Insurance Application and choose from among the following plans:

  • UnitedHealthcare Medicare Advantage PPO (Parts A & B)
  • Anthem BCBS Medicare Advantage PPO (Parts A & B)
  • Kaiser Permanente Senior Advantage HMO (Parts A & B)
  • UnitedHealthcare Medicare Advantage PPO (Part B only)

To participate in a Medicare Advantage Plan, you will have to complete a separate application (see links below). In the future, if you want to change from one Medicare Advantage Plan to another Medicare Advantage Plan, you must notify the DHR – Employee Benefits office in writing.

The Kaiser Senior Advantage HMO is offered to retirees and/or spouses who have both Medicare Parts A and B. The Kaiser Senior Advantage HMO covers in-network services only. If you go out-of-network, the plan will not cover that care. To participate in the plan, you must live within Kaiser’s Senior Advantage Service Area, which is offered in 20 counties in the metro Atlanta area.

If you join this plan, Kaiser Permanente will automatically serve as your Medicare Part D provider. If you are a new member who selects Senior Advantage as your retiree healthcare plan option for 2023, your application will include Part D enrollment information.

For more information, visit or  call Kaiser Permanente Customer Service at 404-233-3700.

UnitedHealthcare Medicare Advantage PPO and Anthem BCBS Medicare Advantage PPO are offered to retirees and/or spouses who have both Medicare Parts A and B. The plans are Preferred Provider Organizations (PPO) that give you the freedom to go to any provider that accepts Medicare and is willing to accept the plan reimbursements and rules.

UnitedHealthcare also offers a Medicare Advantage Part B only plan.

Important Reminders About Medicare Advantage Coverage

Dependent Coverage

If you have dependents (spouse or children) who are not Medicare eligible, and you wish to cover them, you must enroll in either the Anthem BCBS Medicare Advantage (Parts A & B) Split Option Plan or the Kaiser Permanente HMO + Senior Advantage (Medicare) Split Option Plan. Likewise, your dependents will be enrolled in either the Anthem BCBS POS or Kaiser HMO plan, depending on the plan you choose for yourself.

Potential Loss of Coverage

If you sign up for any Medicare Advantage Plan (other than the City-sponsored plans listed above) that may be offered to you directly by various vendors, including just Medicare Part D for prescription drugs, your coverage through the City of Atlanta will be terminated. If you have any questions about this, please call the DHR – Employee Benefits at 404-330-6036 before signing up for another medical plan of any type.

City of Atlanta Medicare Part B Buy-in

Employees hired prior to April 1, 1986, may not have enrolled in Medicare Part B. The City will pay the buy-in penalty for those employees and their spouses age 65 and older. However, retirees and their spouses will be responsible for paying the monthly Part B premium.
