Clinical Context
A 45-year-old adult presents to a primary care clinic during influenza season for routine immunization. The patient has no acute febrile illness and requests annual influenza vaccination. The clinician verifies vaccination history, screens for egg allergy and contraindications, documents informed consent, and administers the intramuscular 0.5 mL trivalent influenza vaccine (90661) in the deltoid. Observation for 15 minutes follows to monitor for immediate adverse reactions. Immunization record, lot number, manufacturer, site, and route are documented in the medical record and submitted for billing. Typical billing occurs under an outpatient office visit or immunization-only encounter at a primary care clinic, community health center, or occupational health setting.
