He directed CMS’s staff liaison to the AMA coding process and participated in the CMS Healthcare Common Procedure Coding System (HCPCS) workgroup to establish and revise HCPCS codes.

While at CMS, John developed policies to improve payment for Medicare Part B drugs, to establish sound policy for ambulance and clinical diagnostic laboratory services, and to ensure appropriate payment to Rural Health Clinics and Federally Qualified Health Centers.
