Checking eligibility and/or benefit information and/or the fact that a service has been preauthorized is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility and the terms of the member’s certificate of coverage applicable on the date services were rendered. If you have any questions, call the number on the member’s ID card.

If you participate in Blue Cross Medicare AdvantageSM plans, you may not bill our members enrolled in QMB, a federal Medicare savings program

QMB patients are dual eligible beneficiaries, which means they are eligible for both Medicare and Medicaid. As a state Medicaid benefit, QMB covers the Medicare Advantage premiums, deductibles, coinsurance and copayments of QMB beneficiaries. QMB beneficiaries are not responsible for Medicare Advantage cost-sharing, or out-of-pocket costs.

For services you provide to QMB patients, you must:

  • Bill both Medicare Advantage and Medicaid
  • Accept Medicare Advantage payments and any Medicaid payments as payment in full

Tips to avoid billing QMB patients

Please ensure that you and your staff are aware of the federal billing law and policies governing QMB. It is against federal law for any Medicare provider to bill QMB patients, whether or not the provider accepts Medicaid. Per your Medicare Provider Agreement, you may be sanctioned if you inappropriately bill QMB patients for Medicare Advantage cost-sharing.

To avoid billing QMB patients, please take these precautions:

  • Understand the Medicare Advantage cost-sharing billing process
  • Be sure your billing software and staff remove QMB patients from Medicare Advantage cost-sharing billing and related collections efforts


Call Customer Service at 1-877-774-8592 to learn more about QMB procedures and ways to identify QMB patients. For more details about QMB, see the Centers for Medicare & Medicaid Services website.
