Do Medicare Excess Charges Actually Happen?

Do Medicare excess charges actually happen? Yes, they can—but they are uncommon because most doctors and other healthcare professionals who bill Medicare participate in Medicare and accept its approved payment amount.

An excess charge can only occur under specific circumstances. The provider must be non-participating, decline Medicare assignment for the particular claim, provide a service subject to the limiting-charge rules, and furnish the service in a state that permits excess charges.

That is considerably different from suggesting that anyone with Medicare Supplement Plan N is routinely exposed to large surprise bills.

Medicare Supplement Plan G covers qualifying Part B excess charges. Plan N does not. However, the realistic risk should be considered alongside the premium difference between the two plans, where you receive medical care, and whether your providers accept Medicare assignment.

Do Medicare Excess Charges Actually Happen in Real Life?

Yes. Medicare Part B excess charges are legally permitted in many states, and some beneficiaries do receive them.

However, they are not a routine part of most people’s Medicare experience.

The Medicare Payment Advisory Commission reports that almost all clinicians billing Medicare’s physician fee schedule participate in Medicare. Participating providers agree to accept Medicare’s approved amount as payment in full.

Even a non-participating provider can choose to accept Medicare assignment for an individual claim. Therefore, seeing a non-participating provider does not automatically mean you will receive an excess charge.

For an excess charge to occur, all these conditions generally must be present:

The provider is enrolled in Medicare but is non-participating
The provider declines assignment for your specific claim
The service is one for which excess charges are permitted
State law does not prohibit the charge
The provider bills more than Medicare’s approved amount

If any one of those conditions is missing, there generally is no excess charge.

Why Medicare Excess Charges Are Uncommon

Most Medicare providers accept assignment.

When a provider accepts assignment, the provider agrees to:

Accept Medicare’s approved amount as payment in full
Bill Medicare directly
Collect only the applicable deductible and coinsurance
Avoid billing a Medicare Part B excess charge

There is also a financial incentive to participate. Medicare generally pays non-participating providers 5% less than the full Medicare Physician Fee Schedule amount.

Non-participating providers can also accept assignment on a claim-by-claim basis. A doctor can therefore be officially non-participating while still accepting Medicare’s approved amount for your particular service.

This is why the number of non-participating providers does not equal the number of excess-charge claims.

How Much Can a Medicare Excess Charge Be?

Medicare commonly describes the limiting charge as no more than 15% above the approved amount for a non-participating provider.

However, that does not mean a doctor can simply add 15% to every Medicare bill.

Medicare generally calculates the approved amount for a non-participating provider at 95% of the full Medicare Physician Fee Schedule amount. The limiting charge can then be up to 115% of that reduced amount.

As a result, the maximum total charge ordinarily equals 109.25% of the full participating fee-schedule amount.

For example, suppose the full Medicare Physician Fee Schedule amount is $100:

Non-participating approved amount: $95
Maximum limiting charge: $109.25
Amount above the non-participating approved amount: $14.25

This calculation can be confusing, but the important point is that the provider cannot charge an unlimited amount and call it a Medicare excess charge.

When Can an Excess Charge Occur?

Excess charges apply to certain Medicare Part B services received from non-participating providers who do not accept assignment.

Possible examples include certain services provided by:

Physicians
Medical specialists
Surgeons
Other healthcare professionals billing Medicare Part B

An excess charge does not apply merely because:

You used Plan N
You traveled outside your home state
A doctor is outside an insurance-company network
You received expensive medical care
A provider is officially non-participating

The provider must actually decline assignment and bill above the applicable Medicare-approved amount.

Plan G and Plan N do not have proprietary doctor networks. Both supplement Original Medicare and can generally be used with any healthcare provider nationwide who accepts Medicare.

Non-Participating Providers Are Not Opt-Out Providers

A non-participating provider is still enrolled in Medicare.

The provider can treat Medicare beneficiaries, submit claims to Medicare, and accept assignment on a claim-by-claim basis. When the provider does not accept assignment, a qualifying excess charge may be permitted.

A provider who has opted out of Medicare is different.

An opt-out provider generally:

Does not submit ordinary claims to Medicare
Uses a private contract with the patient
Requires the patient to agree to pay personally
Is not limited to Medicare’s approved amount under that private contract

Except for certain emergency or urgently needed services, Medicare generally does not pay for care furnished under an opt-out private contract.

Private-contract charges from an opt-out provider are not Medicare Part B excess charges. Plan G’s excess-charge benefit does not turn those private charges into Medicare-covered expenses.

Do Excess Charges Happen in Pennsylvania?

Pennsylvania prohibits healthcare practitioners from balance billing Medicare beneficiaries above the Medicare-approved amount for Medicare-covered services received in Pennsylvania.

Therefore, a doctor cannot impose a Medicare Part B excess charge for a covered service furnished in Pennsylvania merely because the doctor is non-participating.

An opt-out provider using a private contract is a separate situation.

The location of the medical service matters. Pennsylvania’s protection does not necessarily follow a Pennsylvania resident into another state.

If a Pennsylvania resident receives care in a state permitting excess charges, a non-participating provider may be allowed to impose one. Plan G would cover a qualifying excess charge, while Plan N would not.

Does Plan N Leave You at Serious Risk?

Plan N does not cover Medicare Part B excess charges, but that does not automatically make Plan N risky.

Your practical exposure depends on:

Whether your state prohibits excess charges
Where you receive medical care
Whether your doctors accept Medicare assignment
How frequently you use non-participating providers
The annual premium difference between Plan G and Plan N

Someone who receives nearly all medical care in Pennsylvania has very little practical exposure to excess charges because Pennsylvania prohibits them for covered services received in the state.

Someone who frequently schedules care in states where excess charges are permitted may want to investigate whether those particular providers accept assignment.

That still does not mean Plan G will necessarily save money. The additional Plan G premium could be considerably larger than the excess charges someone is realistically likely to encounter.

Is Plan G Worth It Because It Covers Excess Charges?

Plan G covers an additional expense that Plan N does not. Whether that benefit justifies Plan G’s higher premium is a separate question.

Suppose Plan G costs $45 more per month:

$45 × 12 months = $540 in additional annual premiums

You would be paying $540 every year for Plan G’s additional protection from Plan N copays and qualifying excess charges.

That may be worthwhile if predictable expenses are especially important to you. However, it may not be the better financial choice if excess charges are prohibited where you receive care and your anticipated Plan N copays are substantially less than the premium savings.

The decision should be based on actual premiums and realistic exposure—not fear that excess charges happen constantly.

How Can You Avoid Medicare Excess Charges?

Before receiving non-emergency care, ask the provider’s billing office:

Do you accept Medicare?
Do you accept Medicare assignment?
Are you a participating Medicare provider?
Will you accept assignment for my specific service?
Have you opted out of Medicare?
Will I be asked to sign a private contract?

The most important question is whether the provider accepts Medicare assignment.

You can also use Medicare’s provider-search tools to investigate whether a healthcare professional participates in Medicare. Because provider information and billing arrangements can change, confirming directly with the office is still wise.

What Should You Do if You Receive an Unexpected Charge?

An unfamiliar bill is not automatically a valid Medicare excess charge.

First, compare the provider’s bill with your Medicare Summary Notice. Determine:

Whether Medicare covered the service
What Medicare approved
Whether the provider accepted assignment
What Medicare paid
What amount Medicare says you may owe
Whether your Medicare Supplement company processed the claim

If you have Plan G and the bill is a qualifying Part B excess charge, contact your Medicare Supplement company.

If you have Plan N, verify that the charge is legally permitted and calculated correctly before paying it. You can contact Medicare at 1-800-MEDICARE or your State Health Insurance Assistance Program if you need help reviewing the bill.

The Bottom Line: Do Medicare Excess Charges Actually Happen?

Do Medicare excess charges actually happen? Yes—but they require a particular combination of provider status, claim handling, service type, and state law.

Most clinicians billing Medicare’s physician fee schedule participate in Medicare. Non-participating providers can accept assignment for individual claims, and several states prohibit excess charges.

Plan G covers qualifying excess charges, while Plan N does not. That difference is real, but it should be kept in perspective when comparing premiums and likely out-of-pocket expenses.

For many beneficiaries, especially those receiving care in Pennsylvania, excess charges are unlikely to become a significant expense. Someone who regularly uses non-participating providers in states permitting excess charges may place more value on Plan G’s protection.

Frequently Asked Questions

Are Medicare excess charges common?

No. They are possible, but they are uncommon because almost all clinicians billing Medicare’s physician fee schedule participate in Medicare and accept its approved amount as payment in full.

Can any doctor charge 15% more than Medicare approves?

No. A participating provider cannot impose an excess charge. A non-participating provider must decline assignment, the service must be subject to limiting-charge rules, and state law must permit the charge.

Does every non-participating provider charge excess charges?

No. Non-participating providers can accept Medicare assignment on a claim-by-claim basis. An excess charge only becomes possible when the provider does not accept assignment for that claim.

Does Plan N cover Medicare excess charges?

No. Medicare Supplement Plan N does not cover Part B excess charges. However, it still covers the same major standardized hospital benefits as Plan G.

Does Plan G cover Medicare excess charges?

Yes. Medicare Supplement Plan G covers qualifying Part B excess charges when they legally apply.

Can doctors charge excess charges in Pennsylvania?

Pennsylvania prohibits healthcare practitioners from balance billing above Medicare’s approved amount for covered services received in Pennsylvania.

Can a Pennsylvania resident receive an excess charge while traveling?

Possibly. Pennsylvania’s prohibition generally applies to services received in Pennsylvania. An out-of-state provider may impose an excess charge if the other state permits it and the provider does not accept assignment.

Is an opt-out doctor’s bill an excess charge?

No. An opt-out provider generally uses a private contract, and Medicare ordinarily does not pay for those services. Private-contract fees are different from Medicare Part B excess charges.
