For decades, Aetna has made health care costs more affordable for seniors by offering stable and predictably priced Medicare Supplement Insurance plans.

Medicare Supplement Insurance plans (also called 'Medigap') were created to help seniors deal with out-of-pocket costs not covered by Original Medicare’s Part A and Part B. Ten different plans (denoted by letters between A and N) offer different levels and combinations of coverage, regardless of what insurance provider sells it. However, each provider has the freedom to offer some or all of the plans in the states of its choice. It can also price plans as it wishes. It is in ‘pricing’ and ‘plan availability’ that one provider distinguishes itself from another. If in your state Aetna offers the plan of your choice at a good price, it could be the best Medigap option for you. Aetna is a major insurance company that entered the Medicare Supplement market early and has proven itself to be stable and predictable. It offers only an average number of plans but is a very popular provider.

The initial decision regarding the choice of a Medicare Supplement Insurance plan will take place around your 65th birthday. While Aetna’s website is not the most comprehensive and it pushes you towards contacting the company or an intermediary for further information, at age 65 that is not an insurmountable obstacle. It does offer several ways of enrolling. Not having easy access to online information would be a greater inconvenience as you age and perhaps consider moving to Aetna from another company. Beyond that one drawback, Aetna offers few, but excellent plans that serve a senior’s needs regardless of age. Aetna also offers an upfront benefit at the outset: a 12-month rate lock in your first policy year.

Deteriorating health may require more frequent visits to doctors and hospitalizations. Copayments and coinsurance can easily become a financial burden. Aetna’s focus on Medicare Supplement Plans F and G encourages the greatest coverage of all. While the premiums for those plans are also the highest, it is at a time when you most need the health care services that you will appreciate not having to worry about paying for them. An added benefit, especially as your health declines, is access to an Aetna nurse phone line, available 24/7. Often, a simple call can save you a trip to your doctor and bring you much-valued peace of mind. 


  • Aetna promises a 12-month rate lock, that is, no rate increases during your first year.
  • Aetna offers a full refund if you choose to cancel for any reason during a 30-day Free Look period. 
  • Aetna offers different combinations of plans A, B, F, G and N in different states, and are said to be quite competitive on their plans G and N. 
  • As a member, you will have access to a 24/7 nurse phone line that can answer health care questions.
  • Customer service is said to be excellent at Aetna, with wait times that never exceed five minutes.
  • Aetna is the third largest health insurance provider in the nation, with a long history of stable service.


  • Aetna only sells Medicare Supplement Insurance plans in 44 states. If you live in AK, CT, HI, ME, MA, WA or DC, Aetna’s policies are not available.
  • Aetna offers a limited number of different plans and does not offer one of the more popular ones: Plan C.
  • Like other providers, if you apply outside of your initial 6-month Medigap Open Enrollment Period, some medical conditions may cause your application to be declined. If approved, you may be charged higher rates or face up to six months delayed coverage of a pre-existing condition.
  • Getting comparative information on their website is not that easy, and there is a constant push to get you to attend a sales meeting near you, schedule a time for them to call you, schedule an in-home visit or order an information kit.

Bottom Line:

Aetna Medicare Supplement plans help limit the out-of-pocket expenses not covered by Original Medicare (Parts A and B). Aetna distinguished itself as a pioneer by offering major medical insurance plans early on and then, when Medicare was signed into law, being one of the first companies to offer Medicare Supplement plans. It is a company that is seen as stable and predictable: two characteristics seniors are looking for in their health care coverage.

FORTUNE magazine chose Aetna for three years running as the most admired company in the ‘Health Care: Insurance and Managed Care’ category. In 2016, Aetna claimed to have nearly 700,000 members enrolled in its Medicare Supplement plans nationwide, an increase of 119,000 over the prior year. This growth would not have happened if Aetna had anything other than a stellar reputation in the senior community.

Frequently Asked Questions:

If plan benefits are all the same insurer to insurer, what distinguishes Aetna? Aetna is known for being competitive on its Plans G and N. It is also known for its good customer service, both on telephone wait times and on the timeliness of policy issuance.

Are there any additional services or perks offered in choosing Aetna? Aetna promises its policyholders a 12-month rate lock, that is, no rate increases during the first year on a policy. It also offers a full refund if you choose to cancel for any reason during a 30-day Free Look period. 

What is your most popular Medicare Supplement plan that is sold through Aetna? Aetna’s Medigap Plan G is becoming an increasing favorite, showing a 13-percent increase in enrollment in a recent survey. The company has made an effort to keep its rate increases low on this plan. Plan G is similar to Plan F, but does not cover the Part B deductible; its premiums are lower to reflect that fact.
