Plan G vs Plan N: Which Medicare Supplement Is Best?

When you turn 65 and become eligible for Medicare, you’ll face one of the most important healthcare decisions of your retirement: choosing between Plan G and Plan N Medicare supplements. These two plans dominate the supplement market for good reason — they both offer excellent coverage while working seamlessly with Original Medicare. But they work very differently, and the choice you make could save or cost you hundreds of dollars every year.

How Plan G and Plan N Work With Medicare

Both Plan G and Plan N are Medicare supplement plans that work alongside Original Medicare Parts A and B. Unlike Medicare Advantage plans, both supplements give you access to any doctor or hospital nationwide that accepts Medicare — no networks, no referrals, no prior authorizations required.

Here’s where they differ significantly in 2026:

Plan G Coverage:

• You pay the annual Part B deductible of $283
• After the deductible is met and Medicare approves your claims, Plan G covers 100% of your remaining costs
• No copayments, no coinsurance, no additional deductibles
• Most comprehensive supplement available to new Medicare beneficiaries

Plan N Coverage:

• You pay the annual Part B deductible of $283
• $20 copayment for each office visit (up to the plan maximum)
• $50 copayment for each emergency room visit (waived if you’re admitted to the hospital)
• You’re responsible for Part B excess charges, though these are rare

Agent Tip

Many people assume Plan N’s copayments apply to every medical service, but they don’t. The $20 copay only applies to office visits with your doctor — not to lab work, X-rays, or other outpatient services. Those are covered at 100% after your Part B deductible.

Real-World Cost Comparison

Let’s look at actual numbers using Texas as an example for a 65-year-old in good health:

Monthly Premiums:

• Plan G: $165/month
• Plan N: $130/month
• Annual premium savings with Plan N: $420

But premiums are only part of the story. Let’s add in a realistic healthcare scenario: 6 doctor visits plus 1 emergency room visit where you’re not admitted to the hospital.

Plan N Out-of-Pocket Costs:

• 6 doctor visits × $20 copay = $120
• 1 ER visit = $50 copay
• Total copayments: $170/year

Net Annual Savings with Plan N: Approximately $250

Even after paying the copayments, Plan N still saves money in this scenario. However, the math changes as your healthcare usage increases.

Who Should Choose Plan N?

Plan N typically works best for people who:

• Are generally healthy and see a doctor only a few times per year
• Want to save money on monthly premiums
• Don’t mind paying small copayments for the convenience of lower premiums
• Live in states where Part B excess charges are prohibited or rare

Plan N is particularly popular in states like Pennsylvania and New York, where Part B excess charges are prohibited by state law. In these states, you eliminate one of Plan N’s potential drawbacks.

Who Should Choose Plan G?

Plan G makes more sense for people who:

• Have chronic conditions requiring frequent medical care
• Want predictable healthcare costs
• Prefer not to deal with copayments at the doctor’s office
• Can comfortably afford the higher premium for maximum coverage

Agent Tip

If you’re seeing your doctor more than 15-20 times per year, Plan G will likely save you money despite the higher premium. The copayments on Plan N add up quickly with frequent medical visits.

Understanding Part B Excess Charges

One key difference between the plans is how they handle Part B excess charges. These occur when a doctor charges more than Medicare’s approved amount for a service. Plan G covers these excess charges completely, while Plan N leaves you responsible for them.

However, excess charges are relatively rare — fewer than 5% of providers nationwide charge them. Many states have also banned excess charges entirely, making this less of a concern in those areas.

Network Access and Travel Coverage

Both Plan G and Plan N provide identical benefits when it comes to:

• Doctor and hospital access — any provider that accepts Medicare
• Foreign travel emergency coverage — up to $50,000 at 80% reimbursement
• No referrals or prior authorizations required
• Coverage in all 50 states

This makes both plans excellent choices for people who travel frequently or split time between multiple states. You can learn more about Medicare coverage while traveling to understand how these benefits work.

Rate Increases Over Time

Both Plan G and Plan N will experience annual rate increases, but Plan G increases tend to be more predictable. Since Plan G is the most popular supplement plan, insurance companies have larger risk pools and more stable claims experience.

Plan N’s smaller enrollment can sometimes lead to more volatile rate increases, though this varies significantly by insurance company and state.

Making Your Decision

The choice between Plan G and Plan N often comes down to your personal healthcare philosophy and financial situation. If you value predictability and maximum coverage, Plan G is worth the extra premium. If you’re comfortable with small copayments in exchange for premium savings, Plan N can be an excellent choice.

Remember that you have guaranteed issue rights when you first become eligible for Medicare. This means you can choose either plan without medical underwriting, regardless of your health status. However, timing is crucial — these rights only last for six months after you enroll in Medicare Part B.

Frequently Asked Questions

Can I switch from Plan N to Plan G later?

In most states, switching from Plan N to Plan G after your initial enrollment period requires medical underwriting. However, some states like California have birthday rules that allow limited changes without health questions.

Do both plans cover prescription drugs?

Neither Plan G nor Plan N includes prescription drug coverage. You’ll need a separate Medicare Part D plan for drug coverage, regardless of which supplement you choose.

What happens if I move to a different state?

Both plans provide coverage nationwide, so moving doesn’t affect your benefits. However, you may need to find a new insurance company in your new state, as not all insurers operate nationally.

Are the copayments on Plan N the same everywhere?

Yes, Plan N’s copayments are standardized by federal law. You’ll pay $20 for office visits and $50 for ER visits regardless of which insurance company you choose or which state you live in.

Which plan offers better value for someone with chronic conditions?

Plan G typically provides better value for people with chronic conditions because the copayments on Plan N can add up quickly with frequent doctor visits. If you’re seeing specialists regularly, Plan G’s comprehensive coverage often saves money despite the higher premium.
