Medicare Part B Excess Charges in North Carolina: How to Protect Yourself from Unexpected Bills

When transitioning to Original Medicare, most North Carolina seniors understand that Medicare Part B covers doctor visits, outpatient services, and preventative care. However, many retirees are surprised to learn about a hidden cost known as a Medicare Part B excess charge. Even if a doctor accepts Medicare patients, they may still bill you beyond what Medicare approves if they do not agree to Medicare's standard assignment rate.

At Seniors Insurance Hub, we help North Carolina retirees navigate Medicare rules to eliminate financial surprises and protect their retirement savings. In this guide, we break down what excess charges are, how state laws apply in North Carolina, and how choosing the right Medigap policy shields you from unexpected medical expenses.

What Are Medicare Part B Excess Charges?

To understand excess charges, it helps to understand how Medicare classifies medical providers. Under Medicare Part B, healthcare providers fall into three main categories:

• Participating Providers: Doctors and hospitals that accept "Medicare assignment." They agree to accept the Medicare-approved amount as full payment for covered services. You pay only your standard 20 percent coinsurance after meeting your Part B deductible.
• Non-Participating Providers: Healthcare providers who accept Medicare patients but do not agree to accept Medicare assignment for all services. These providers can charge up to 15 percent more than the Medicare-approved amount. That additional 15 percent is called an excess charge.
• Opt-Out Providers: Doctors who do not participate in Medicare at all and have signed private contracts with patients. Medicare pays nothing for services from opt-out providers.

According to official rules from Medicare.gov Part B Cost Guidelines, non-participating doctors are capped by federal law from charging more than 15 percent above the Medicare-approved rate. You, the beneficiary, are responsible for paying 100 percent of that excess charge out of pocket unless your Medigap policy covers it.

How Do Excess Charges Work in North Carolina?

Some states (such as Pennsylvania, New York, and Massachusetts) prohibit doctors from billing excess charges under state law known as MOM (Medicare Overcharge Measure) regulations. However, North Carolina does not ban Medicare Part B excess charges.

This means North Carolina doctors who do not accept assignment are legally allowed to bill up to the maximum 15 percent excess charge to patients residing anywhere across the state, from Charlotte and Raleigh to Greensboro and Wilmington.

For example, if a specialist performs an outpatient procedure in North Carolina with a Medicare-approved amount of $1,000, a non-participating doctor could charge up to $1,150. Medicare pays 80 percent of the approved amount ($800), leaving you responsible for your 20 percent coinsurance ($200) plus the full $150 excess charge.

Which Medigap Plans Cover Medicare Part B Excess Charges?

The most effective way for North Carolina seniors to protect themselves against unexpected excess charges is by selecting a Medicare Supplement (Medigap) plan that includes excess charge coverage.

• Medigap Plan G: Covers 100 percent of Medicare Part B excess charges. Once you pay the small annual Part B deductible, Plan G pays all remaining coinsurance, copays, and excess charges.
• Medigap Plan F: Also covers 100 percent of excess charges, but is only available to beneficiaries who became eligible for Medicare before January 1, 2020.
• Medigap Plan N: Does not cover Part B excess charges. While Plan N offers lower monthly premiums, beneficiaries are responsible for excess charges if they see a non-participating doctor, in addition to small copays for office and emergency room visits.

Research published by the Kaiser Family Foundation highlights that over 95 percent of doctors nationwide accept Medicare assignment. However, seeing specialists, visiting out-of-state facilities, or seeking emergency care while traveling can increase your likelihood of encountering non-participating providers.

3 Steps to Avoid Medicare Excess Charges in NC

Whether you currently hold Medigap coverage or are evaluating options for the upcoming enrollment period, follow these three steps to protect your budget:

1. Ask Doctors If They Accept Medicare Assignment: Before scheduling appointments or procedures, confirm directly with the office billing department: "Does the physician accept Medicare assignment for this service?" Simply asking if they accept Medicare is not enough, as non-participating doctors accept Medicare patients while still billing excess fees.
2. Choose Medigap Plan G for Full Peace of Mind: If you travel frequently or prefer the freedom to see any specialist nationwide without checking assignment status, Medigap Plan G provides complete coverage against excess charges (CMS Medigap Coverage Overview).
3. Consult Local Insurance Specialists: Guidance from the North Carolina Seniors Health Insurance Information Program (SHIIP) or an independent advisor at Seniors Insurance Hub helps compare plan rates in your county so you select the right balance of premium cost and benefit protection.
