What distinguishes Category II codes from others?

Category II codes are a unique set of codes in the Current Procedural Terminology (CPT) coding system specifically designed to aid in the tracking of healthcare quality and performance. These codes are used for performance measurement and provide supplementary information about the quality of care delivered, including data related to outcomes and specific clinical activities.

This tracking capability is crucial for healthcare providers as it allows them to gather data that can improve patient care, demonstrate the effectiveness of their treatments, and participate in pay-for-performance programs. Unlike Category I codes, which are primarily used for billing procedures and services, Category II codes provide a means to enhance the understanding of quality measures and adherence to best practices within clinical settings.

The characteristics associated with the other choices do not apply to Category II codes, as they are not solely numeric (there are both alphanumeric and numeric codes in the coding system), they do not focus on experimental procedures (that is more applicable to Category III codes), and they are not limited to surgical procedures, as they encompass a range of clinical activities across various specialties.
