Medicare AEP 2027 in Tennessee — what to know.
Oct 15 - Dec 7, 2026. The Annual Enrollment Period is your once-a-year chance to switch Medicare Advantage plans, switch Part D drug plans, or move between Original Medicare and Medicare Advantage. Plans you choose during AEP take effect January 1, 2027.
Why this AEP matters in Tennessee
Tennessee has roughly 1.5M Medicare beneficiaries, of whom about 51% are enrolled in a Medicare Advantage plan. AEP is when their plans can change — and when you can change yours.

BlueCross BlueShield of Tennessee remains the largest insurer in the state and a major MA carrier. Humana is headquartered in Louisville (just over the border) and has very strong Tennessee presence. Vanderbilt Health and HCA TriStar both have broad MA network participation.
Your AEP 2027 checklist for Tennessee
Your current plan mailed an Annual Notice of Change (ANOC) in late September. It lists every benefit, copay, network, and drug change for 2027. Don't recycle it — read it.
Networks change every year. Confirm your primary care doctor and any specialists are still in-network for 2027 — directly with the plan, not just on the website.
Formularies (covered drug lists) change annually. A drug that was Tier 2 in 2026 may move to Tier 4 in 2027 — tripling your copay. Run your meds through the plan's 2027 formulary.
Don't just renew. Compare your current plan against at least 2 alternatives — including Original Medicare + Medigap if you've never considered it. Best plan in 2026 is rarely best in 2027.
The Part D out-of-pocket cap stays at $2,000 in 2027. If you take expensive drugs, that cap dramatically changes the math — many people who couldn't afford Eliquis or Jardiance in past years now can.
After Dec 7 you generally can't change your Medicare Advantage plan until next AEP — except for the limited Open Enrollment window (Jan 1 - Mar 31) which only allows one change.

Many Tennessee retirees winter in Florida. National PPO plans or Medigap travel better than Tennessee-specific HMO plans.
