Reopenings Rendering NPI (National Provider Identifier) Adjustment Request Form (RNP 237)

Form RNP 237PDF (Reopenings Rendering NPI Adjustment Request Form) will allow you to change the rendering practitioner's National Provider Identifier (NPI) on a line item of a previously processed claim. This form is to change only the performing physician/practitioner NPI and not the billing NPI. To change the billing NPI, please submit Form GRF 679PDF (Reopenings Adjustment Request Form). If the change results in lower payment amount, please submit a request to Overpayment Recovery (OPR).

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.
