The CMS developed the Correct Coding Initiative (CCI) to promote national correct coding methodologies and to control improper coding leading to inappropriate payment in Part B claims. The purpose of the CCI edits is to ensure the most comprehensive groups of codes are billed rather than the component parts. Additionally, CCI edits check for mutually exclusive code pairs. These edits were implemented to ensure that only appropriate codes are grouped and priced. The unit-of-service edits determine the maximum allowed number of services for each HCPCS code.

To access the CCI edits from the CMS website, click on the link below. For PT's and OT's in private practice as well as physician owned therapy clinics, click on NCCI Edits--Physicians. For all other settings, click on NCCI Edits--Hospital Outpatient PPS. Private practices and physician owned clinics are always one version ahead of all other settings.
