Category II Codes are supplemental CPT codes used for performance measurements, designed to assist in data collection for quality of care evaluation. These codes complement the existing CPT code system and are important for quality improvement practices.
Supplemental CPT codes used for performance measurements are referred to as Category II Codes. These codes are an optional set of tracking codes that can be utilized for performance management. By providing a mechanism for reporting, these codes facilitate data collection about the quality of care. Category II codes are distinct from Category I which describe procedures and services and Category III which denote emerging technologies. Rather, these codes are primarily used to provide additional information about patient health outcomes for performance measurement.
The use of Category II Codes is not mandated, but it is encouraged as part of quality improvement initiatives.
