Clinical & Coding Specifications

The visit involves obtaining a detailed history (including review of systems and past medical history), performing a detailed physical examination, and establishing a low-complexity plan of care. Typical presenting problems include headaches (R51), nonspecific abdominal pain (R10.9), or fatigue (R53.83), or patients presenting for routine adult or gynecological examinations (Z00.00, Z01.419) with new concerns identified during the visit. The clinical workflow includes check-in and triage, rooming with vitals, clinician history and examination, documentation of assessment and low-complexity medical decision making, and patient counseling with follow-up instructions. The encounter may occur in person in the office or via synchronous telemedicine when appropriate.
