Medicare Plan N Hidden Fees: Excess Charges Explained

If you’re considering Medicare Plan N because of its lower premiums compared to Plan G, there’s something you need to know about potential hidden fees that could catch you off guard. While Plan N offers solid coverage at an attractive price point, excess charges represent one cost that Plan N doesn’t cover — and understanding this gap could save you from unexpected bills down the road.

What Makes Plan N Different from Other Medicare Supplements

Medicare Plan N sits in a unique position among Medicare supplement plans. It offers comprehensive coverage with lower monthly premiums than Plan G, but comes with specific cost-sharing requirements that beneficiaries need to understand.

Plan N requires you to pay:

• The Medicare Part B deductible ($283 for 2026)
• Copays of up to $20 for office visits
• $50 copays for emergency room visits (waived if admitted to the hospital)
• Part B excess charges (the “hidden fee” we’re discussing)

The copays are straightforward and predictable. The excess charges, however, are where things get murky for many beneficiaries.

Understanding Medicare Part B Excess Charges

Excess charges occur when you visit a doctor who doesn’t accept Medicare assignment. Here’s how it works: Medicare sets an approved amount for every medical service covered under Part B. Doctors who accept Medicare assignment agree to accept this approved amount as payment in full (after you pay your deductible and coinsurance).

However, doctors who don’t accept Medicare assignment can legally charge up to 15% more than Medicare’s approved amount. This additional 15% is called an excess charge, and it’s money that comes directly out of your pocket when you have Plan N.

Agent Tip

In over 10 years working with thousands of Medicare clients, I’ve found that excess charges on Plan N are extremely rare when you take simple precautions. The key is being proactive about verifying your providers accept Medicare assignment.

For example, if Medicare approves $100 for a specialist visit, a non-participating doctor could charge you up to $115. With Plan N, you’d pay that extra $15 out of pocket. With Plan G, excess charges are covered at 100%.

Which Services Are Subject to Excess Charges

Excess charges only apply to services covered under Medicare Part B, which includes:

• Doctor visits and consultations
• Outpatient care and procedures
• Diagnostic tests and lab work
• Durable medical equipment
• Mental health services
• Physical and occupational therapy

Important to note: Hospital services covered under Medicare Part A are not subject to excess charges. The excess charge risk is specifically tied to Part B services.

Three Proven Ways to Avoid Excess Charges

1. Verify Your Doctors Accept Medicare Assignment

The most effective way to avoid excess charges is to confirm that your healthcare providers accept Medicare assignment. You can do this by:

• Visiting Medicare.gov and using the “Find care providers” tool
• Calling your doctor’s office directly and asking if they accept Medicare assignment
• Asking before scheduling any appointment with a new provider

Most doctors (about 96% nationwide) do accept Medicare assignment, making excess charges relatively uncommon.

2. Live in a State That Prohibits Excess Charges

Eight states have laws that prohibit doctors from charging excess fees to Medicare beneficiaries:

• Connecticut
• Massachusetts
• Minnesota
• New York
• Ohio
• Pennsylvania
• Rhode Island
• Vermont

If you live in one of these states, Plan N holders face zero risk of excess charges, making Plan N an even more attractive option compared to Plan G.

3. Consider Switching to Plan G

If you’re concerned about potential excess charges or frequently see specialists who don’t accept Medicare assignment, switching to Plan G might make sense. Plan G covers excess charges at 100%, eliminating this concern entirely.

However, remember that switching Medicare supplement plans typically requires medical underwriting unless you qualify for a guaranteed issue period.

Agent Tip

Before switching from Plan N to Plan G solely due to excess charge concerns, calculate the annual premium difference. Often, the additional premium cost for Plan G exceeds what you’d realistically pay in excess charges, especially if you’re diligent about using providers who accept assignment.

Plan N vs Plan G: Cost Comparison

Coverage Area	Plan N	Plan G
Part B Deductible	You pay	You pay
Office Visit Copays	Up to $20	Covered 100%
Emergency Room Copays	$50 (waived if admitted)	Covered 100%
Part B Excess Charges	You pay	Covered 100%
Monthly Premium	Lower	Higher

Real-World Impact of Excess Charges

While excess charges can theoretically add up, the practical impact for most Plan N beneficiaries is minimal. Here’s why:

First, the vast majority of healthcare providers accept Medicare assignment. Second, excess charges are capped at 15% of Medicare’s approved amount. Third, you can easily avoid them by choosing providers who accept assignment.

For most people, the annual savings from Plan N’s lower premiums far exceed any potential excess charges they might encounter, especially when they’re proactive about provider selection.

When Plan N Makes Sense Despite Excess Charges

Plan N can be an excellent choice when:

• You primarily see doctors who accept Medicare assignment
• You live in a state that prohibits excess charges
• You want lower monthly premiums and don’t mind paying small copays
• You’re willing to do basic research on provider participation before scheduling appointments

The key is understanding your healthcare patterns and being comfortable with the small amount of due diligence required to avoid excess charges.

How to Research Provider Participation

Before seeing any new healthcare provider with Plan N, take these simple steps:

Visit Medicare.gov and use their provider search tool. Enter your ZIP code and the type of provider you need. The search results will clearly indicate which providers accept Medicare assignment.

When calling to schedule appointments, simply ask: “Do you accept Medicare assignment?” This one question can save you from unexpected excess charges.

For ongoing care relationships, confirm participation status annually, as providers can change their Medicare participation status.

Frequently Asked Questions

What is the maximum excess charge I could face with Plan N?

Excess charges are limited to 15% above Medicare’s approved amount for any given service. For example, if Medicare approves $200 for a procedure, the maximum excess charge would be $30.

Can I avoid all excess charges by only seeing doctors who accept Medicare assignment?

Yes, doctors who accept Medicare assignment cannot charge excess fees. They must accept Medicare’s approved amount as payment in full (after your deductible and coinsurance are met).

Do excess charges apply to hospital stays?

No, excess charges only apply to Medicare Part B services like doctor visits, outpatient procedures, and diagnostic tests. Hospital stays are covered under Part A and are not subject to excess charges.

Should I choose Plan G instead of Plan N to avoid excess charges?

This depends on your situation. Compare the annual premium difference between Plan G and Plan N in your area. Often, Plan N’s savings exceed potential excess charge costs, especially if you use providers who accept assignment.

What states prohibit excess charges completely?

Eight states prohibit excess charges: Connecticut, Massachusetts, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, and Vermont. Plan N holders in these states have no excess charge risk.
