myCGS Part B Automated Reopenings: Form RMF 780

Form RMF 780screenshot (Reopenings Modifier Adjustment Request Form) will allow you to request simple corrections specific to adding, replacing, or deleting a modifier on a line item of a previously processed claim.

Only one claim can be corrected per form; up to 12 line items per claim.

NOTE: In order to complete the form accurately, you must have access to your Remittance Advice (RA). If you download your RA from a billing service or clearinghouse, the line items may be in a different sequence, which will affect the processing on this form. We suggest accessing your RA directly from the myCGS Web Portal.

Also, to avoid issues with legibility, we encourage you to complete the form online, and then print it.
