Hospital Outpatient PPS
This area provides resources to Medicare-based OPPS information which may assist providers in better understanding Wyoming Medicaid OPPS priced claims.

Hospital Outpatient PPS Transmittals
This area provides quarterly updates to the Outpatient Code Editor (OCE) software for OPPS modifications. When searching quarterly transmittals, please note that
Appendix M: Summary of Modifications resources can be found for the following subjects:

• Diagnosis Code Changes
• Status Indicator Changes
• HCPCS changes
• Composite Ambulatory Payment Classifications (APCs)

Note: Transmittals are not always a direct crosswalk to Wyoming Medicaid. These are reflections of CMS Manual changes, whereby, Wyoming Medicaid may opt to modify certain aspects therein.

Also, if a procedure is priced under OPPS, the Status Indicator (SI) of the assigned APC will override the SI of the procedure. Please note that not all possible APCs and SIs would be included in the fee schedule given that all lines on the claim may impact assigned APC and SI.
