Clinical & Coding Specifications
Clinical Context
A 2-month-old infant presents to a pediatric clinic for routine immunizations during a well-child visit. The infant receives the Haemophilus influenzae type b (Hib) vaccine formulation containing a PRP–T conjugate administered intramuscularly in the anterolateral thigh. The clinical workflow includes vaccine screening for contraindications and allergies, parental consent, preparation of the single-dose syringe, administration with aseptic technique, documentation of lot number, expiration date, manufacturer, site and route of administration, and provision of the Vaccine Information Statement (VIS). Observation for 15 minutes post-injection for immediate adverse reactions is completed, and the visit is coded using 90648 for the vaccine product and an appropriate evaluation and management code for the well-child visit if billed separately.
