What Is AARP Medigap? 
A Medigap Plan purchased through AARP means you will have Medicare Supplement insurance through United Healthcare . Medigap Plans A , B , C , F , K , L and N are sold by AARP . In some states , AARP has Medigap SELECT plans . For example , if you have Medigap SELECT Plan F or C , you get all the benefits of those plans -- except you have to use the hospitals in the network directory to receive full hospital care benefits . Applicants must be AARP members or live in the same household and share the same AARP membership number . It 's important to note that Medigap Plan benefits are standardized ; so , Plan F with AARP is the same Plan F with another insurance company . The difference is the price . An independent agent specializing in Medicare Supplement insurance can help you compare an AARP premium to other insurance companies . Many people like to do their own research and sometimes will end up with an insurance company such as AARP because it 's easy to call up and enroll . However , this ` easy ' process can often times equate to a higher premium . By working with an independent agent , you can compare an AARP premium to other insurance company premiums for the same Medigap Plan you desire . This will make sure you are getting the best priced Medigap Plan . Thank you for reading my reply . Please let me know if I can be of further assistance .
