Volume leaders are not the high-payment codes. Provision Of Covid-19 Test, Nonprescription Self-Administered And Self-Collected Use, Fda Approved, Authorized Or Cleared, One Test Count is in the top volume slice but not the highest Medicare payments; Sipuleucel-T, Minimum Of 50 Million Autologous Cd54+ Cells Activated With Pap-Gm-Csf, Including Leukapheresis And All Other Preparatory Procedures, Per Infusion is in the high-payment set without matching volume rank.
