QMB Billing Protection in New York: What to Do When a Provider Bills You

The Federal Rule

Under 42 U.S.C. § 1396a(n)(3)(B) and 42 C.F.R. § 447.15, Medicare providers and suppliers are federally prohibited from billing a Qualified Medicare Beneficiary for Medicare Part A or Part B cost-sharing. That means no bills for:

• The Part B annual deductible ($283 in 2026)
• Part B coinsurance (typically 20% of the approved amount)
• Part A hospital deductible ($1,736 per benefit period)
• Skilled nursing facility coinsurance ($217/day for days 21–100)
• Any copays on Medicare-covered services

The prohibition applies to every Medicare-participating provider in every state. In New York, NYSDOH policy reinforces the federal rule. The provider's only recourse is to bill Medicaid for the QMB cost-sharing amount — and accept whatever Medicaid pays, even if it is zero.

Why Bills Keep Coming Anyway

Despite the federal prohibition, QMB members regularly receive bills. The reasons are predictable:

The provider's billing system does not recognize QMB status. Medicare claims processing systems flag QMB as a billing code, but many provider offices do not check it. The bill generates automatically.

The office confuses QMB with standard Medicaid. Some providers assume that if Medicaid does not pay the full cost-sharing amount, the patient owes the rest. Under QMB rules, the patient owes nothing regardless of what Medicaid pays.

Third-party billing companies do not know the law. Outsourced billing operations may apply standard collection procedures without checking QMB status.

How to Stop an Illegal QMB Bill

Step 1: Call the provider's billing department. State that the patient is a QMB enrollee and that federal law prohibits balance billing for Medicare cost-sharing. Ask them to check the patient's Medicaid eligibility through eMedNY — it will show active QMB status.

Step 2: Put it in writing. Send a letter (certified mail, return receipt) to the billing office stating:

• The patient's name, Medicare number, and Medicaid CIN (Client Identification Number)
• That the patient is enrolled in QMB
• That 42 U.S.C. § 1396a(n)(3)(B), 42 C.F.R. § 447.15, and the Balanced Budget Act of 1997 prohibit billing QMB enrollees for Medicare cost-sharing
• That the bill must be withdrawn and any amounts paid refunded

Keep a copy of the letter and the return receipt.

Step 3: Report the violation. If the provider continues billing:

• File a complaint with the New York State Department of Health
• Report the provider to CMS at 1-800-MEDICARE
• Contact the Medicare Rights Center (1-800-333-4114) for advocacy support

CMS has stated repeatedly that a provider who bills a QMB enrollee may face sanctions including removal from the Medicare program. In practice, most providers withdraw the bill once they receive a written notice citing the law.

If It Has Gone to Collections

A QMB-prohibited bill sent to a collections agency does not become a legitimate debt. Contact the collections agency in writing, provide proof of QMB status, and cite the federal prohibition. Under the Fair Debt Collection Practices Act, disputing the debt in writing within 30 days of receiving the validation notice requires the collector to pause collection on the disputed amount until it sends verification. The QMB billing protection applies separately; include proof of QMB status when disputing the bill.

Do not pay a QMB-prohibited bill to make it go away. If you already paid, federal compliance rules require the provider to refund the improper QMB cost-sharing payment; request the refund in writing.
