Is Aetna Medicare Enhanced (PPO) (H5521-607) ending in 2027?
Yes. Aetna won't offer Aetna Medicare Enhanced (PPO) in 2027. It ends December 31, 2026, for at least 49 members in 29 counties in Michigan.
What this means for you
What happens when your plan ends
Aetna Medicare Enhanced (PPO) will not exist in 2027. If you don't pick a new plan, you'll be moved to Original Medicare on January 1, 2027 with no drug coverage. You can choose a new plan during Annual Enrollment (October 15 – December 7, 2026). Because your plan is ending, you also get a Special Enrollment Period through February 28, 2027, and the right to buy certain Medigap policies with no health questions.
