Scenario: Client seen for psychotherapy and we bill 90837 to the primary, which is Medicare. Client has a secondary state-funded indigent coverage, but they only process HCPCS level II codes. Is it appropriate, i.e., legal to crosswalk the 90837 CPT code over to an equivalent H0004 HCPCS psychotherapy code in order to successfully bill the secondary?
