Claim Submission Error (CSE) Data

Claim Submission Errors (CSEs) result from an editing process that returns electronic and paper claims to the provider as "unprocessable." This occurs if the claim contains incomplete or invalid information. 

Returning a claim as "unprocessable" does not mean CGS will physically return every claim you submit with incomplete or invalid information. The term "Return to Provider" or "RTP" is used to refer to the many processes utilized by CGS for notifying you that your claim cannot be processed. The MA130 remark code on the remittance advice (RA) identifies an RTP claim/service.

RTP claims/services have no Appeal rights, as no "initial determination" can be made on an unprocessable claim/service due to the invalid or incomplete information submitted. This means that these claims cannot be corrected through Redeterminations, the first level of the appeals process. In addition, RTP claims/services do not qualify for correction through the Reopenings process. The error(s) found on these claims/services must be corrected and then resubmitted as NEW claims.

Please note that RTP claims/services create unnecessary costs to the Medicare program so should be avoided.

Below is a list of the monthly top RTP error categories. Refer to resources available to you to avoid future billing errors.
