Top Claim Submission Errors (Reason Codes) and How to Resolve

Claim submission errors (CSEs) cause your billing transactions to either reject or move to your Return to Provider (RTP) file for correction, and create unnecessary costs to the Medicare program. Below is a list of the monthly top RTP and reject errors listed by provider type. Click on the specific reason code to access resources you can use to avoid future billing errors. For instructions on how to correct claims in your RTP file, refer to the Fiscal Intermediary Standard System (FISS) Guide: Chapter Five: Claims CorrectionExternal PDF.

NOTE: As a Medicare provider, you are responsible to ensure the information submitted on your billing transaction is correct and compliant with Medicare regulations. Providers should be aware that action may be taken when they demonstrate a pattern of submitting claims inappropriately, incorrectly or erroneously, including a referral to the Office of Inspector General (OIG) for Medicare.
