Arizona Medigap (Medicare Supplement) Plans
Medigap plans in Arizona help cover out-of-pocket costs not paid by Original Medicare, including the Part A deductible, Part B coinsurance, and skilled nursing facility copays. Medigap plans are standardized by federal law, meaning Plan G from one carrier covers the same benefits as Plan G from another carrier. The difference is premium cost.
Plans available in Arizona: A, B, C, D, F, G, K, L, M, N (Plans C and F available only to those Medicare-eligible before January 1 2020)
Most popular plan: Plan G is the most popular Medigap plan in Arizona. Plan G covers all gaps in Original Medicare except the annual Part B deductible ($240 in 2026). Plan N is the most popular lower-premium alternative, with small copays for some doctor visits and ER visits.
Pricing method: Arizona uses community-rated Medigap pricing. This is the most favorable method for consumers because premiums are the same regardless of age. Your premium will not increase simply because you get older.
The average monthly Plan G premium for a 65-year-old in Arizona is approximately $161. Plan N averages approximately $120 per month. Actual premiums vary by carrier, age, gender, tobacco use, and zip code. Always compare quotes from at least three carriers.
Arizona Medigap Switching Rights
Arizona does not have a Medigap birthday rule. Your primary opportunity to buy or switch Medigap plans without medical underwriting is during your initial Medigap Open Enrollment Period, which lasts 6 months starting when you first enroll in Medicare Part B at age 65 or older.
After your initial OEP closes, you may face medical underwriting if you apply for a new Medigap policy. However, federal law provides guaranteed issue rights in specific situations, such as losing employer coverage or leaving a Medicare Advantage plan during your first year.
Arizona guaranteed issue protections: Arizona follows federal guaranteed issue rights only. There is a standard 6-month Medigap Open Enrollment Period when first enrolled in Part B at age 65 or older. Arizona does not provide additional state-level guaranteed issue periods beyond the federal requirements. Arizona also does not mandate Medigap access for beneficiaries under age 65, though 2026 legislation has been introduced for ALS and ESRD beneficiaries under 65.
Arizona Medicare Advantage (Part C)
Approximately 1484871 people in Arizona are enrolled in Medicare. About 51% of Arizona Medicare beneficiaries choose Medicare Advantage plans, with the remainder on Original Medicare with or without Medigap supplement coverage.
Medicare Advantage plans in Arizona are offered by private insurers as an alternative to Original Medicare. Most MA plans include prescription drug coverage (Part D) and often add dental, vision, and hearing benefits. However, MA plans use provider networks, which can limit your choice of doctors and hospitals.
Key Medicare Advantage considerations in Arizona:
- Networks matter: HMO plans require you to use in-network providers except in emergencies. PPO plans allow out-of-network care at higher cost.
- $0 premium plans: Many Arizona MA plans have $0 monthly premiums (you still pay your Part B premium).
- Maximum Out-of-Pocket (MOOP): MA plans cap your annual spending, unlike Original Medicare which has no cap.
- Star ratings: CMS rates MA plans 1-5 stars. Higher-rated plans often have lower costs and better coverage.
Top Medicare Advantage carriers in Arizona by enrollment:
- UnitedHealthcare
- Humana
- Blue Cross Blue Shield of Arizona
- Aetna
- Banner Health
Arizona Medicare Financial Help Programs
Arizona offers Medicare Savings Programs (MSPs) that help low-income Medicare beneficiaries pay for premiums, deductibles, and copays. The four programs are:
- QMB (Qualified Medicare Beneficiary): Pays Part A and Part B premiums, deductibles, coinsurance, and copays.
- SLMB (Specified Low-Income Medicare Beneficiary): Pays Part B premiums only.
- QI (Qualifying Individual): Pays Part B premiums (limited funding, first-come first-served).
- QDWI (Qualified Disabled Working Individual): Pays Part A premiums for disabled workers.
Arizona MSP eligibility: QMB: 1350/month individual and 1824/month couple; SLMB: 1478/month individual and 1992/month couple; QI: 1660/month individual and 2239/month couple. Arizona has no asset limit for Medicare Savings Programs.
Apply through your local SHIP office or your state Medicaid agency for free help determining eligibility.
Top Medicare Insurance Companies in Arizona
Top Medigap carriers in Arizona:
- AARP/UnitedHealthcare
- Mutual of Omaha
- WMI Mutual
- Humana
- Transamerica
When comparing carriers, focus on premium cost (for identical standardized Medigap plans, benefits are the same — only price differs), financial strength ratings from AM Best (A or higher), customer satisfaction ratings, and claims processing speed.
Arizona Medicare Enrollment Periods
Understanding Medicare enrollment deadlines prevents costly late enrollment penalties:
- Initial Enrollment Period (IEP): 7-month window around your 65th birthday (3 months before, birthday month, 3 months after). Enroll in Parts A and B during this period.
- Medigap Open Enrollment: Standard federal 6-month Medigap Open Enrollment Period beginning the first day of the month you turn 65 and are enrolled in Part B. Arizona does not extend this period beyond the federal standard.. During this period, insurance companies cannot deny you Medigap coverage or charge higher premiums based on health conditions.
- Annual Enrollment Period (AEP): October 15 through December 7 each year. Switch between Original Medicare and Medicare Advantage, change MA plans, or add/change Part D drug plans.
- Medicare Advantage Open Enrollment Period (OEP): January 1 through March 31. Switch MA plans or return to Original Medicare (and add a Medigap plan, subject to underwriting).
- Special Enrollment Periods (SEP): Available when you lose employer coverage, move, or qualify for other life events.
Additional Arizona Medicare protections: Arizona requires insurers to offer issue-age-rated Medigap plans (one of only four states with this requirement). Arizona eliminates asset limits for Medicare Savings Programs making MSP qualification easier. Arizona does not guarantee Medigap access for beneficiaries under 65. No birthday rule or continuous open enrollment protections beyond federal standards.
