CMS crosswalk: not offered in 2027

Not offered in 2027

Aetna Medicare Enhanced (H5521-122) is not offered in 2027: the CMS plan crosswalk of October 1, 2026 lists it as terminated, so its coverage ends December 31, 2026. The plan's $1,000 dental allowance, $150 eyewear allowance, $500 hearing aid (both ears) allowance and $120 over-the-counter allowance end with it; other plans sold in its counties may offer them (each county page lists the 2027 plans). 1,209 people were enrolled in it in September 2026. They can choose another plan during open enrollment, October 15 to December 7, 2026, to have no gap (or by the end of February, with coverage from the first of the next month); anyone who does not join another plan before it ends moves to Original Medicare, without a drug plan unless they join one (members with Extra Help or full Medicaid are enrolled in one by Medicare).

What can members do, and by when?

October 15 to December 7, 2026: Open enrollment: join another Medicare Advantage plan, or Original Medicare with a drug plan. Coverage starts January 1, 2027.
December 8, 2026 to the end of February 2027: A special enrollment period because the plan is leaving: you can still join a plan, but coverage starts the first day of the month after you join, so choose by December 31 to have no gap.
If you do nothing: You are enrolled in Original Medicare when the plan ends, without a drug plan unless you join one; if you have Extra Help or full Medicaid, Medicare enrolls you in a drug plan automatically.
Without a drug plan: Going 63 days or more in a row without drug coverage can mean a late enrollment penalty if you join a drug plan later; joining by the end of February keeps a January and February gap under 63 days, waiting longer does not.
If you choose Original Medicare: You have a guaranteed right to buy Medigap Plan A, B, C, D, F, G, K or L sold in your state by any insurance company; if you were new to Medicare on or after January 1, 2020, Plans D and G take the place of C and F. Apply from 60 days before to 63 days after the plan ends; the policy starts once your Medicare Advantage coverage ends. Other Medigap plans are not covered by this right.
If you have Medicaid or Extra Help: You can switch to a different drug plan, or leave a Medicare Advantage plan for Original Medicare with a drug plan, once a calendar month; the change starts the first day of the next month.
