I work for a multi-specialty clinic. Often times our patients will see more than one provider on the same date, but of different specialties (i.e. PCP and cardiologist). We are having issues with some of the commercial or MA plans denying the second provider's claim against the first provider claim stating duplicate or previously processed. We do bill as a group under the same tax ID. Does anyone have any insight on how to submit these claims so the insurance will see that the providers are of different specialties and process and pay both claims without having to appeal each denial?
