Providers and suppliers must not bill Qualified Medicare Beneficiaries (QMBs) for Medicare Part A or Part B cost sharing, including deductibles, coinsurance, and copayments.

Federal law prohibits all Original Medicare and Medicare Advantage providers and suppliers from billing QMBs for Part A and Part B cost sharing; these protections apply to all dates of service on which a patient is a QMB.

Violations may breach Medicare provider agreements and may result in sanctions.

QMBs may not elect to pay Medicare cost-sharing amounts; do not charge a patient enrolled as a QMB for Medicare cost-sharing even if their QMB benefit is from a different state than the state of care.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Implement processes to identify QMB status before billing (use MAC online portals, E1 transactions for pharmacies, third-party vendor eligibility verification, automated state Medicaid eligibility systems, Medicare RAs and MSNs, or patient documentation).

Recall any bills for QMB Medicare cost sharing and refund any collected cost-sharing amounts to the QMB; remedy any QMB billing or collections.

Determine and bill the appropriate state Medicaid program for Medicare cost-sharing payment; obtain Medicaid remittance advice (RA) before claiming Medicare bad debt when applicable.

State enrollment and crossover

States must allow enrollment of all Medicare-enrolled providers and suppliers for submitting claims for state payment of Medicare cost sharing even if a provider or supplier category isn’t recognized in the Medicaid State Plan.
Many states and Medicaid managed care plans participate in electronic crossover systems to automatically process Medicare-adjudicated QMB claims for Medicaid payment; when crossover occurs it is noted on the Medicare RA.

Provider Compliance and Remediation

Note

Identify QMBs, stop improper billing, and bill the state Medicaid program

Identify QMB status before billing; recall and refund any improper QMB cost-sharing bills or collections; and bill the appropriate state Medicaid mechanism for Medicare cost-sharing payment. Providers must use available eligibility tools (MAC portals, vendor/HETS verification, Medicaid eligibility systems, E1 transaction for pharmacies, MA plan processes) to confirm QMB status prior to charging, promptly recall bills or refund collected amounts from QMBs, and determine state billing/enrollment steps (including electronic crossover systems) to obtain Medicaid payment for Medicare cost sharing.

Check QMB eligibility via your MAC's online provider portal and register with your MAC as needed.
Use third-party vendor or clearinghouse eligibility verification (HETS) or state Medicaid eligibility systems; pharmacies may use the E1 transaction for real-time responses.
If bills were sent or sent to collections, recall the bills and refund any collected cost-sharing from QMBs.
Determine how to submit claims to the state (many states use electronic crossover); contact the state Medicaid Agency for provider enrollment details.
