Clinical & Coding Specifications

Clinical Context

A 45-year-old adult presents to a primary care clinic during influenza season requesting routine immunization. The patient has no acute illness, reports prior receipt of influenza vaccine in previous years, and has no known severe allergy to vaccine components. Nursing verifies vaccine history, obtains informed consent, screens for contraindications, and documents the lot number and expiration. The vaccine Q2036 (Flulaval, split virus, intramuscular, for individuals ≥3 years) is prepared and administered intramuscularly in the deltoid. Post-vaccination observation for 15 minutes is performed for syncope risk. Documentation includes vaccine product (Q2036), date, site, route, lot number, manufacturer, and VIS (vaccine information statement) given. If the patient has an acute moderate or severe illness, administration is deferred and the encounter is coded accordingly. Billing is submitted to the patient’s insurer with appropriate modifiers if applicable (e.g., AS for clinic provided service or one of the listed modifiers if reporting unusual circumstances).
