Professional Providers: Important Change Coming 1/1/18 for Correcting Claims

Effective January 1, 2018, Highmark will no longer accept requests for claim corrections via telephone or NaviNet® investigation. Providers instead must submit corrected (replacement) claims electronically. Because electronic replacement claims normally process in the same time frame as an original claim, your adjustments will likely process faster than those changes requested via phone or NaviNet investigation. There are three valid Frequency Type claims: 1, 7 and 8. The original claim number assigned by Highmark is required for all Frequency Type adjustment claims.  When submitting a correction, send the claim with all changes exactly as the claim should be processed.
