2 FTEs vs a department. Most hospitals have entire departments to handle insurer coding and some even have departments just to handle insurer disputes.
Coding is a different layer. Everything needs coding, whether for gov't or commercial payers. So the folks doing this coding can't be separated out for commercial. In fact, it's kind of the opposite:
CPT codes (for procedures) - these are defined by AMA, but mandated by CMS (i.e., Medicare/caid). Because the gov't mandated them, the commercial payers adopted them too.
HCPCS codes (equipment and supplies) - defined by CMS.
ICD-10-PCS codes (hospital inpatient stuff) - defined by CMS.
