Indiana QMB Balance Billing: Your Federal Protections Explained

The Federal Law Is Clear

If you have QMB status in Indiana, no Medicare provider — doctor, hospital, lab, imaging center, or supplier — can bill you for Medicare Part A or Part B cost-sharing. That means zero liability for deductibles, coinsurance, and copayments. The legal basis is Section 1902(n)(3)(B) of the Social Security Act and 42 CFR § 447.15.

This protection applies to all Medicare-enrolled providers, whether they participate in Medicaid or not. It applies in Original Medicare and in Medicare Advantage. There are no exceptions.

Why Bills Still Show Up

Despite the federal prohibition, QMB enrollees routinely receive bills for the 20% Part B coinsurance or the Part A hospital deductible ($1,736 per benefit period in 2026). This happens because:

• Provider billing systems don't always flag QMB status correctly
• Indiana Medicaid's "lesser-of" payment methodology sometimes results in a $0 Medicaid payment to the provider for the crossover claim
• Some billing departments misinterpret a $0 Medicaid payment as authorization to bill the patient

A $0 Medicaid payment does not give the provider permission to bill you. Under Indiana Health Coverage Programs rules and federal law, the provider must write off the balance entirely.

What to Do When You Get a Bill

Follow this sequence:

Step 1 — Check the dates. Compare the date of service on the bill with the QMB effective date on your DFR Notice of Action. QMB only covers services from the effective date forward.

Step 2 — Contact the provider in writing. Send a letter to the billing department citing 42 U.S.C. § 1396a(n)(3)(B), and attach a copy of your QMB approval notice or an IHCP eligibility printout from the FSSA Benefits Portal. Request that the balance be zeroed and any credit reporting be corrected.

Step 3 — Escalate to CMS. If the provider refuses to clear the balance, call 1-800-MEDICARE (1-800-633-4227) and file a formal QMB Billing Violation Complaint. CMS will issue a binding warning letter to the provider. Penalties for non-compliance include contract termination and civil money penalties.

Step 4 — State-level complaints. If collection actions continue, notify the Indiana Medicaid Ombudsman and file a complaint with the Indiana Attorney General's Consumer Protection Division.

Protecting Yourself Going Forward

Keep a copy of your DFR Notice of Action showing QMB status (category MA L) with you or easily accessible. When you visit a new provider, ask the office to verify your QMB status before treatment. You can also print an eligibility verification from fssabenefits.in.gov.

If a provider sends a bill to collections, the same federal protections apply. Give the collection agency proof of QMB status and dispute the charge as Medicare cost-sharing that federal law bars the provider from billing.
