Medicare Part B excess charges are covered by

• A. Medicare Part A
• B. Medicare Advantage
• C. Medicaid
• D. Medicare Supplemental insurance

Answer: (C)

The question tests how excess charges in Medicare Part B are handled when a person has additional coverage. Excess charges arise when a doctor who doesn’t accept Medicare assignment bills more than Medicare approves for a Part B service. Medicare pays its approved amount, and the provider can bill the patient for the difference, unless another payer steps in.

Medicaid can cover those excess charges for individuals who are eligible, acting as a secondary payer and paying the portion Medicare does not cover. This protection helps low‑income beneficiaries avoid large balance bills for Medicare services. The other options don’t specifically address excess charges in this typical coordination of benefits: Part A is hospital coverage and unrelated to outpatient Part B excess charges; Medicare Advantage plans have their own rules and are not guaranteed to cover these excess amounts; Medigap policies primarily cover coinsurance and deductibles and generally do not cover the excess charges that can occur with nonparticipating providers.
