In which scenarios are Category II codes typically used?

Category II codes are specifically designed to facilitate performance measurement tracking in healthcare settings. They serve as supplemental tracking codes that provide information on the quality of care being delivered. These codes allow healthcare providers to collect data on specific patient care activities, enabling the evaluation and improvement of patient outcomes and healthcare processes.

Utilizing Category II codes helps in assessing the effectiveness of treatments and identifying areas for quality improvement, which plays a crucial role in patient care optimization. By incentivizing the reporting of evidence-based measures, these codes contribute to a more comprehensive understanding of how care is being provided and its impact on patient health.

In contrast, the other answer choices do not accurately reflect the primary purpose of Category II codes. They are not intended solely for billing purposes, nor are they used for documenting patient allergies or coding surgical procedures, which are functions covered by different categories of codes within the CPT system.
