Key payers relevant to coverage and reporting include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context and typical sites of service, guidance on which payers are addressed in the analysis, and what kinds of benchmarks and policy implications are commonly associated with immunization documentation measures. The publication outlines common reporting considerations, how this measure fits into hepatitis care pathways, and where national payers and Medicare commonly focus quality measurement efforts.

Clinical & Coding Specifications
Clinical Context
A 48-year-old patient with chronic hepatitis C presents to an outpatient primary care clinic for routine follow-up and preventive care. During the visit the clinician reviews vaccination history, documents that the patient is hepatitis C–positive and confirms that the patient either receives a hepatitis B vaccine injection that day or has previously received the hepatitis B vaccine series. The clinical workflow includes review of immunization records, patient consent for vaccination if administered, preparation and administration of the hepatitis B vaccine by a qualified clinician or nursing staff, documentation of vaccine lot number and site, and updating the electronic medical record and immunization registry. Typical sites of service are outpatient clinic, community health center, or ambulatory infusion and immunization clinics where adult hepatitis B vaccination is offered to patients aged 18 years and older with hepatitis C.
