Tips on Completing a Credit Balance Report (Form CMS-838)

Credit balance reports with missing or invalid information are rejected and are not considered received for the quarter. A corrected report must be received by the due date for the quarterly reporting period. Please review the following tips to avoid a rejected Credit Balance Report.

Note: A separate Medicare Credit Balance Report (CMS-838) should be submitted for each Medicare provider number.

If you have no credit balances as of the last day of the reporting quarter a signed and dated certification page must still be submitted.

  • Provider 6-Digit Number – Be sure to complete a separate Medicare Credit Balance Report for each provider number (also known as a PTAN). Do not submit one Medicare Credit Balance Report with multiple providers listed.
  • Quarter Reporting Period – Include the end date of the reporting quarter in a month, day, year format (e.g., 9/30/12 or September 30, 2012).
