Best Medicare Supplement Plans in Arizona: What AZ Seniors Need to Know

Published June 13, 2026 · LeadGod editorial team

What Are the Best Medicare Supplement Plans in Arizona?

If you have Original Medicare in Arizona, you already know it doesn't cover everything. Copays, deductibles, and coinsurance can add up fast. That's where Medicare Supplement plans — also called Medigap — come in. These plans help fill the "gaps" that Original Medicare leaves behind.

But with so many plan options and insurance carriers in Arizona, it can be hard to know where to start. This guide breaks down the most popular Medigap plans available to Arizona residents, what they cover, and how to think about choosing the right one for your situation.


How Medicare Supplement Plans Work in Arizona

Medicare Supplement plans are sold by private insurance companies, but they are standardized by the federal government. That means a Plan G from one company must offer the same core benefits as a Plan G from another company — the main difference is price and customer service.

In Arizona, you can enroll in a Medigap plan if you are enrolled in Medicare Part A and Part B. The best time to enroll is during your Medigap Open Enrollment Period, which begins the month you turn 65 and are enrolled in Part B. During this window, insurance companies cannot deny you coverage or charge you more due to health conditions.

Outside of that window, insurers in Arizona can use medical underwriting, which could affect your eligibility or premium — confirm current rules with a licensed agent or the Arizona Department of Insurance and Financial Institutions.


The Most Popular Medigap Plans in Arizona

There are 10 standardized Medigap plans (labeled A through N). Here are the ones Arizona seniors most commonly choose:

Plan G — Most Comprehensive for New Enrollees

Plan G is one of the most popular choices for people new to Medicare (those who turned 65 on or after January 1, 2020). It covers:

  • Medicare Part A coinsurance and hospital costs
  • Medicare Part B coinsurance or copayments
  • Blood (first 3 pints)
  • Part A hospice care coinsurance
  • Skilled nursing facility coinsurance
  • Part A deductible
  • Foreign travel emergency care (up to plan limits)

The only cost you pay out of pocket is the Part B deductible (set annually by Medicare — confirm the current year's amount at Medicare.gov). After that, Plan G covers nearly everything else.

Plan N — Lower Premiums, Some Cost-Sharing

Plan N offers similar coverage to Plan G but at a lower monthly premium. The trade-off: you pay small copays (up to $20 for office visits, up to $50 for emergency room visits that don't result in inpatient admission) plus the Part B deductible. If you're relatively healthy and don't visit the doctor frequently, Plan N can save you money over time.

Plan F — Still Available to Some

Plan F was the gold standard of Medigap for years because it covered the Part B deductible too. However, it is no longer available to people who became Medicare-eligible on or after January 1, 2020. If you were eligible before that date, you may still be able to enroll — check with an Arizona-licensed agent.

High-Deductible Plan G — Budget-Friendly Option

This version of Plan G has a high annual deductible (set by Medicare each year — verify current amount) before coverage kicks in. Once you meet the deductible, it provides the same benefits as standard Plan G. This can work well for people who want catastrophic protection at a lower monthly cost.


What Medigap Plans Don't Cover

No matter which plan you choose, Medicare Supplement plans generally do not cover:

  • Prescription drugs (you'll need a separate Part D plan for that)
  • Dental, vision, or hearing care
  • Long-term care
  • Private-duty nursing

If prescription coverage matters to you, look into standalone Part D drug plans available in Arizona alongside your Medigap policy.


How to Compare Plans and Prices in Arizona

Because the benefits of each lettered plan are the same regardless of insurer, the smartest way to shop is to:

  1. Decide which plan letter fits your health needs and budget.
  2. Compare premiums from multiple carriers — prices for the same plan can vary significantly between companies in Arizona.
  3. Check the insurer's rate-increase history — some companies raise premiums more aggressively than others as you age.
  4. Look at the pricing structure — companies use community rating, issue-age rating, or attained-age rating. Attained-age plans may start cheaper but increase as you get older.

You can use the Medicare Plan Finder tool at Medicare.gov or work with a licensed Arizona broker who can pull quotes from multiple carriers at no cost to you.


Arizona-Specific Tips for Medigap Shoppers

  • No state mandate for guaranteed issue beyond federal rules. Arizona follows federal Medigap regulations, so your Open Enrollment Period is your most protected window.
  • Snowbirds take note. If you spend part of the year out of state, Medigap can be a strong choice because it follows you anywhere in the U.S. where Medicare is accepted — unlike many Medicare Advantage plans, which may have network restrictions.
  • Free help is available. Arizona's State Health Insurance Assistance Program (SHIP), called Arizona SHIP, offers free, unbiased counseling to help you compare plans.

Frequently Asked Questions

H3: When is the best time to enroll in a Medigap plan in Arizona?

The best time is during your Medigap Open Enrollment Period — the six-month window that starts the month you're 65 or older and enrolled in Medicare Part B. During this period, insurers cannot deny you or charge higher premiums based on health history.

H3: Can I switch Medigap plans later if my needs change?

Yes, but outside of your Open Enrollment Period, you may be subject to medical underwriting in Arizona. There are some limited Special Enrollment periods that may allow switching without underwriting — a licensed agent or Arizona SHIP counselor can walk you through your options.

H3: Is Medicare Supplement the same as Medicare Advantage?

No. These are two different paths. Medicare Supplement (Medigap) works alongside Original Medicare (Parts A and B). Medicare Advantage (Part C) replaces Original Medicare with a private plan that typically includes network restrictions. You generally cannot have both at the same time.

H3: How much do Medigap plans cost in Arizona?

Premiums vary based on the plan letter, your age, the insurance company, and where you live in Arizona. Plan G premiums for a 65-year-old can range from roughly $100 to $200+ per month depending on the carrier — always compare multiple quotes before enrolling.

H3: Do Medigap plans cover prescription drugs in Arizona?

No. Medicare Supplement plans do not include drug coverage. You would need to enroll in a separate Medicare Part D prescription drug plan to cover medications.


Choosing the right Medicare Supplement plan is one of the most important financial decisions you'll make as you enter retirement. The good news: you don't have to figure it out alone.
