Clinical & Coding Specifications
Clinical Context
A primary care clinician or community health nurse documents and reports targeted hepatitis C screening for patients born between 1945 and 1965. A 58-year-old patient born in 1966 presents for an annual wellness visit; the clinician reviews birth year-based screening criteria, confirms the patient was born between 1945 and 1965, obtains consent, performs venipuncture for hepatitis C antibody testing, and orders confirmatory HCV RNA testing if the antibody is reactive. The typical workflow includes eligibility confirmation by birth year, brief risk-factor review, laboratory draw in the outpatient clinic or community screening event, specimen processing by the affiliated laboratory, and follow-up communication of results. Typical site of service is an outpatient clinic, community health center, or preventive screening event. Common payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare. Relevant documentation includes the patient’s date of birth, informed consent for screening, test ordered and specimen collected, and follow-up plan for positive or indeterminate results.
