Provider Compliance, Verification, and Billing Procedures

Documentation Required

Provider compliance and verification actions

Identify whether a patient is a QMB and confirm they do not owe Medicare cost sharing before billing. Use multiple verification sources and document the result.

Access your Medicare Administrative Contractor's (MAC) online provider portal to check eligibility and QMB status.
Request eligibility verification from third-party vendors, billing agencies, or clearinghouses and confirm their products reflect QMB data from the HIPAA Eligibility Transaction System (HETS).
Review Medicare Remittance Advices (RAs) and patient Medicare Summary Notices (MSNs) for QMB indicators.
Use an automated state Medicaid eligibility verification system or contact the state Medicaid agency to verify QMB status and learn enrollment/crossover procedures.
Ask the patient for proof of QMB status (Medicaid ID card, MSN, or other documentation).
Pharmacies: submit the Medicare Eligibility Verification (E1) transaction for real-time Part A/B/D enrollment and QMB status responses.
If you are a Medicare Advantage (MA) provider, contact the MA plan for procedures to identify QMB status before and after claim submission.

Billing Rule

Billing and bad debt procedure

Bill the state Medicaid program for Medicare cost sharing and obtain the state Medicaid remittance advice before claiming any unpaid Medicare cost sharing as Medicare bad debt. Do not bill or attempt to collect Part A or Part B cost sharing from a QMB.

Federal law prohibits billing QMBs for Part A and Part B cost sharing — do not bill QMB members even if Medicaid does not pay.
Bill the appropriate state Medicaid program to determine the state's liability for Medicare cost sharing; nearly all states and many Medicaid MCOs participate in electronic crossover processing for QMB claims.
Do not claim Medicare bad debt until you have: 1) billed the state for Medicare cost sharing and 2) received the Medicaid remittance advice (RA) documenting the state’s response.
Recall any bills or collection actions for QMB cost sharing and refund any amounts collected to the QMB.
States must allow enrollment of all Medicare-enrolled providers/suppliers for submitting claims for state payment of Medicare cost sharing; contact the state Medicaid agency for enrollment and submission guidance.
Certain providers/suppliers may seek Medicare bad debt only after following CMS rules (see 42 CFR 413.89 and Provider Reimbursement Manual, Part 1, Chapter 3).
