Where Medigap fits in your Medicare
Original Medicare (Part A and Part B) pays most of your covered costs — but not all. You're left with deductibles, coinsurance, and copays, and there's no annual out-of-pocket maximum in Original Medicare on its own. That open-ended exposure is the gap Medigap policies are designed to help close.
Medigap policies are sold by private insurers but standardized by the federal government and labeled with letters (such as Plan G or Plan N). Because they're standardized, a given lettered plan covers the same things no matter who sells it — what differs is price and service. Medigap pairs with Original Medicare, not Medicare Advantage, and doesn't include drugs, so people on this path usually add a stand-alone Part D plan.
This guide explains how the standardized plans and your enrollment rights work in Sierra Vista, Arizona. We explain the framework — we don't rank plans or quote specific premiums.
Medicare Supplement (Medigap)
The standardized Medigap plans in 2026
Medigap policies are standardized by federal law: a plan with a given letter covers the same benefits no matter which insurance company sells it. So the letter tells you what is covered — what differs between companies is price and service. Plans C and F are no longer available to people who became eligible for Medicare on or after January 1, 2020. This grid is a factual reference; it is not a ranking or a recommendation.

How people get Medicare in Cochise County
(MA penetration in Cochise County)
MA penetration from CMS enrollment data; Medigap share is an estimate. U.S. average is about 54% Medicare Advantage. These are area-level figures, not plan-specific.
The 2027 numbers, from shared to plan-specific
Start with what's fixed for everyone. The standard Part B premium is $202.9 per month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it), and Part A is premium-free for most people who paid Medicare taxes long enough while working.
On the drug side, Part D has real guardrails for 2027: a deductible capped at $700 and, a hard $2,400 ceiling on your out-of-pocket costs for covered prescriptions — the old coverage gap is gone.
Higher earners pay more for Parts B and D through an income-related adjustment called IRMAA, which for 2026 starts above $109,000 in annual income for an individual and is based on your 2024 tax return. Most people fall below that line and pay the standard amounts. The 2027 brackets will be posted when CMS releases them.
Everything past that is plan-specific: the premiums, copays, and coverage details of an individual Advantage or Medigap plan change from plan to plan and year to year. Rather than quote or rank those, we point you to Medicare's Plan Finder and a licensed agent for your exact numbers.

Medicare Advantage Open Enrollment. From January 1 – March 31, if you're already in an Advantage plan you get one chance to switch plans or return to Original Medicare.
