Clinical & Coding Specifications
Clinical Context
A healthy adolescent patient (age 11–15 years) presents to a primary care pediatric clinic for routine immunizations. The patient is scheduled to receive the adolescent–dosage hepatitis B vaccine administered intramuscularly on a two–dose schedule. The clinical workflow includes registration and insurance verification, review of immunization history and allergies, vaccine informed consent, pre-vaccination screening (contraindications and precautions), preparation of the appropriate adolescent-dose vaccine vial or syringe, intramuscular injection (usually anterolateral thigh for younger adolescents or deltoid for older adolescents), documentation of lot number and administration site in the electronic medical record and immunization registry, observation for 15 minutes for adverse reactions, billing using 90743, and submission of the claim to the patient’s payor. Typical site of service is an outpatient clinic or pediatrician’s office. Relevant providers include pediatricians, family medicine physicians, nurse practitioners, physician assistants, and registered nurses who are credentialed to administer vaccines.
