Texas QMB Balance Billing Protection — What to Do When a Doctor Bills You
The Law Is Clear: Providers Cannot Bill QMB Recipients
Federal law under Section 1902(n)(3)(B) of the Social Security Act and 42 CFR § 447.15 prohibits Medicare-enrolled providers from billing Qualified Medicare Beneficiaries for Part A and Part B cost sharing. That includes deductibles, coinsurance, and copayments — on Original Medicare and Medicare Advantage plans alike.
This isn't optional or situational. It applies whether the provider participates in Texas Medicaid or not. A doctor who accepts Medicare but doesn't accept Medicaid still cannot bill a QMB patient for cost-sharing amounts.
Why It Happens Anyway
Billing offices routinely send QMB recipients invoices for the 20% coinsurance, the Part B deductible, or the Part A hospital deductible. Three patterns account for most violations:
The billing system doesn't flag QMB status. Many provider billing departments check Medicaid enrollment but not QMB-specific status. Your parent's QMB designation may not appear in the provider's eligibility lookup, especially if the provider only checks a standard Medicaid portal.
The Texas Medicaid payment is zero. Under the state's "lesser-of" payment formula (1 TAC § 354.1253), Texas Medicaid pays the lesser of the full Medicare cost-sharing amount or the difference between the Medicare paid amount and the Texas Medicaid fee schedule. Because state fee schedules are frequently lower than Medicare rates, the Medicaid payment to the provider is often $0. Some billing offices interpret a $0 state payment as permission to bill the patient. It isn't — the zero-dollar Medicaid payment legally satisfies the beneficiary's entire obligation.
Collection agencies don't know QMB rules. When a provider sends an unpaid balance to collections, the agency rarely has the information or authority to verify QMB status.
Four Steps to Stop an Illegal Bill
Send written proof of QMB status to the billing office. Include a copy of the HHSC Form H1009 (Notice of Eligibility), the Medicare card, and any QMB identification. Request immediate billing reversal in writing.
Issue a written demand for a collection hold. Notify the billing manager that balance billing a QMB recipient violates 42 U.S.C. § 1396a(n)(3)(B) and 1 TAC § 354.1253. Request written confirmation that the balance has been zeroed and any collection activity stopped.
File a complaint with CMS. Call 1-800-MEDICARE (1-800-633-4227) to lodge a formal QMB balance billing compliance complaint against the provider. CMS tracks these complaints and can take enforcement action.
Contact legal aid if bills persist. If a provider continues billing after written notice, or if a collection agency is threatening credit action, contact Lone Star Legal Aid or Texas RioGrande Legal Aid for free legal representation.
