CPT 99213 is a billing code used by healthcare providers to report an evaluation and management (E/M) service for an established patient. The code is used to describe a typical outpatient office visit where the patient's condition is stable and requires a moderate level of medical decision-making.

The service usually involves a review of the patient's medical history and a focused physical examination of the affected body system. Providers may also discuss the patient's symptoms, treatment options, and any other relevant medical issues during the visit.

CPT 99213 is commonly used by primary care physicians, internists, and other healthcare providers who treat a variety of medical conditions in an outpatient setting. The code's description includes a standard set of criteria that healthcare providers must meet in order to accurately report the service to insurance companies and receive proper reimbursement for their services.
