What N782 means

N782 focuses on coinsurance, the percentage of the allowed amount Medicare leaves for the patient on many services. For a Qualified Medicare Beneficiary, that coinsurance cannot be billed to the patient. The alert asks you to look for coinsurance you may already have collected, for example through payments at check-in or statements that went out.

Coinsurance tends to accumulate across many visits, so a single N782 may point to a broader pattern on the account.

What to do

  1. Review the account’s payment history for coinsurance paid by the patient.
  2. Refund any coinsurance collected on Medicare-covered services.
  3. Submit the coinsurance to Medicaid, or the Medicaid managed care plan, as subsequent payer.
  4. Stop patient statements for Medicare cost-sharing on this account.
  5. Recheck QMB status periodically, since it can change.

N782 FAQ

Does N782 mean I'm being paid the coinsurance?

No. It means you cannot collect the coinsurance from the patient. Medicaid may pay part or all of it as the subsequent payer, depending on the state.

Can I send the patient a statement for coinsurance?

No. Statements for Medicare cost-sharing should not go to QMB patients. Suppress them for these accounts.

Does this apply to Medicare Advantage patients?

QMB billing protections generally apply to Medicare Advantage enrollees as well. Check the plan's instructions for billing Medicaid.
