The Window Matters. So Does What Happens After It Closes.

The most consequential decision in your Medicare enrollment isn't which plan you pick — it's when you apply for a Medicare Supplement. Miss the timing, and your options change. We help Arizonans understand exactly where they stand, then find the right Medigap plan for the long run.

What Is a Medicare Supplement Plan and What Does It Cover?

A Medicare Supplement plan — also called Medigap — is private insurance that works alongside Original Medicare (Parts A and B) to cover costs Medicare leaves behind. That includes things like copayments, coinsurance, and the Part A deductible. Without a Medigap policy, those out-of-pocket costs can add up quickly, especially if you use your coverage often.

Medigap plans are standardized by federal law. That means every plan sold under the same letter — Plan G, Plan N, and so on — covers exactly the same benefits regardless of which insurance company sells it. The differences between carriers are premium, how that premium is calculated, and the company's history of rate increases over time.

The Six-Month Window You Cannot Afford to Miss

When you turn 65 and enroll in Medicare Part B, a six-month Medigap open enrollment period begins automatically. During this window, insurance carriers in Arizona cannot deny your application, cannot charge you more based on your health history, and cannot make you wait for coverage of a pre-existing condition.

Once that window closes, Arizona law permits carriers to use medical underwriting. That means they can review your health history, charge higher premiums based on what they find, or decline your application altogether. This is the single most common irreversible mistake we see in Medicare planning — people assume they can shop for a Medigap policy whenever they're ready, and they wait too long.

Apply during your open enrollment period. It is the one time in your Medicare life when every carrier has to say yes.

How Arizona Prices Medigap Plans — and Why Year One Isn't the Whole Story

Not all Medigap premiums are structured the same way, and the difference matters far more than most people realize. Arizona carriers use three pricing methods:

Community-Rated

Everyone in the same geographic area pays the same premium regardless of age. Rates can still increase over time, but your age itself is never the reason.

Issue-Age-Rated

Your premium is based on your age when you first buy the policy and does not increase simply because you get older. Starting younger typically means a lower base rate that holds more predictably over time.

Attained-Age-Rated Plans and Long-Term Cost

Your premium starts lower but increases as you age. These policies often look like the best deal at 65. By 75 or 80, they frequently are not.

Attained-Age-Rated

Your premium starts lower but increases as you age. These policies often look like the best deal at 65. By 75 or 80, they frequently are not.

Why This Matters More Than the First-Year Premium

The cheapest plan today is not always the cheapest plan at 80. We compare pricing structures — not just first-year costs — so you can see what your coverage is likely to cost you across a ten- or twenty-year horizon. Arizona has both issue-age and attained-age policies in the market, and knowing which type you're buying changes the entire conversation.

Plan G and Plan N: What's Actually Different

Because Medigap benefits are standardized, comparing Plan G to Plan N comes down to a specific trade-off, not a complicated coverage analysis.

Plan G covers the Medicare Part B excess charges and leaves you responsible only for the annual Part B deductible. Plan N covers the same categories with two differences: you pay a copay of up to $20 for some office visits and up to $50 for emergency room visits that don't result in inpatient admission, and Plan N does not cover Part B excess charges. In exchange for accepting those out-of-pocket exposures, Plan N typically carries a lower monthly premium.

Which one makes more sense depends on how often you use your coverage, which providers you see, and how the premiums are structured for your age and zip code. We run those numbers with you — not for you in a vacuum.

What Medigap Does Not Cover

Medicare Supplement plans Arizona residents purchase do not include prescription drug coverage. If you have a Medigap policy, you will need a separate Medicare Part D prescription drug plan to cover your medications.

Medigap also does not cover dental, vision, hearing, or long-term care. We can help you look at those separately if they're part of what you need.
