UnitedHealthcare AARP® Medicare Supplement Insurance Plan with MedicareRx Prescription Drug Plans

AARP® Medicare Supplement Insurance Plans offer Medicare-eligible retirees an opportunity to choose from a variety of standardized plans (e.g. Plans A-N) to help pay for some or all of the retiree’s out-of-pocket costs not covered through Medicare Part A and Part B.

These Medicare supplemental insurance plans are also known as “Medigap” plans. Each plan offers a different level of benefits, and monthly premiums vary accordingly. Because there are so many plans and variables, you must contact UnitedHealthcare for details.

Guaranteed Issue Period

These plans are underwritten by UnitedHealthcare Insurance Company. AARP Medicare Supplement Plans may require medical underwriting if you are outside of the guaranteed issue period when coverage may be subject to approval.

If you are switching from a County medical plan, you are eligible for guaranteed issue. In cases where coverage is denied, you and any enrolled dependent will remain in the coverage in place prior to the application to the Medicare supplement plan or have the option to change to another plan provided you do so before Annual Enrollment ends.

Prescription Drugs

Unlike most other plans where the medical and prescription benefits are part of a package, UHC-AARP's medical and prescription plans require separate enrollment. County retirees who enroll in an AARP medical plan must also enroll in an AARP® MedicareRx Plan. The AARP MedicareRx Plans are available to retirees across the U.S. and in the five U.S. territories.

You cannot enroll in a stand-alone Medicare Part D plan, such as the AARP MedicareRx Plans, without also enrolling in their medical plan. They offer a national pharmacy network with access to more than 65,000 pharmacies. In addition, the plan’s drug list includes thousands of brand-name and generic drugs. To assist in your decision, you can give AARP a list of medications and ask for advice about costs and coverage.

To enroll in a UHC-AARP plan, select and enroll in one of their Medicare supplement plans as well as one of their Prescription Drug (Rx) plans. Again, you must enroll in both plans. All enrollees in these plans (i.e. retiree and their dependents) must be enrolled in both Medicare Part A and Part B AND be at least age 65 in order to elect the AARP® plans.
