Credit Balance Reports
CMS requires a Credit Balance Report (CMS-838) be submitted within 30 days after the end of each quarter for all providers participating in the Medicare program.
A credit balance exists when a facility receives an overpayment for a Medicare service, for example:
- A facility is paid twice for the same service either by Medicare or by Medicare and another insurer
- A facility is paid for services planned but not performed or for non-covered services
- A facility is overpaid because of errors made in calculating beneficiary deductible and/or coinsurance amounts
- A facility bills and is paid for outpatient services included in a beneficiary's inpatient claim
Submit Credit Balance Reports via Credit Balance 838 Forms fax number by the due dates below.
