Sierra Vista grew around Fort Huachuca, and its Medicare population includes an unusually high share of military retirees. That makes the coverage conversation here different from anywhere else in Arizona.
TRICARE For Life and Medicare
If you are a military retiree, TRICARE For Life works as secondary coverage behind Medicare — and it requires you to have Part B. Drop Part B and you lose TRICARE For Life.
It is a strong combination. Medicare pays first, TRICARE picks up most of the remainder, and TRICARE's prescription coverage generally counts as creditable for Part D purposes, so you usually do not need a separate drug plan.
Where it gets delicate: adding a Medicare Advantage plan on top changes how Medicare pays, which changes how TRICARE coordinates behind it. That deserves a conversation before you enrol, not after. More on veterans and Medicare →
VA health care is not the same thing
VA care and TRICARE For Life are different programmes with different rules. VA care is delivered at VA facilities and does not let you delay Part B without penalty. Many Sierra Vista residents have some combination of VA, TRICARE and Medicare, and the combination is worth mapping out precisely rather than assuming.
Cochise County
Sierra Vista is in Cochise County with its own plan menu, smaller than the Phoenix or Tucson markets. Specialty referrals often go to Tucson, roughly 75 miles northwest, so a plan's Pima County network is worth checking alongside what is available locally.

Common questions
I have TRICARE For Life. Do I need Part B?
Yes. TRICARE For Life requires Medicare Part B — if you drop Part B you lose TRICARE For Life. TRICARE then works as secondary coverage behind Medicare, and its prescription coverage generally counts as creditable, so a separate Part D plan is usually unnecessary.
Should I add a Medicare Advantage plan to TRICARE For Life?
It is possible but needs careful review. A Medicare Advantage plan changes how Medicare pays, which changes how TRICARE coordinates behind it. This is a situation where a short conversation before enrolling is worth far more than untangling it afterwards.
