CMS crosswalk: not offered in 2027

Not offered in 2027

Aetna Medicare Partial Dual (H3312-089) 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 $100 eyewear allowance and $180 over-the-counter allowance end with it; other plans sold in its counties may offer them (each county page lists the 2027 plans). 1,104 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, and because its members have Medicaid, Medicare enrolls them in a drug plan.

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.
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.
Help choosing
A special needs plan member can get free one-on-one help from the State Health Insurance Assistance Program (SHIP), or from the state Medicaid office for plans that work with Medicaid.
