    Clinical & Coding Specifications

    Clinical Context

    A typical patient scenario involves a parent or adult patient presenting to a primary care clinic or preventive medicine visit to discuss recommended vaccinations for the patient or a dependent. The provider conducts focused immunization counseling that lasts greater than 10 minutes up to 20 minutes but no vaccines are administered during that visit. Common reasons include vaccine hesitancy, detailed review of vaccine schedules (for example, influenza, Tdap, HPV, or COVID-19 series), discussion of risks and benefits, addressing prior adverse reaction concerns, coordination for future vaccination appointments, or counseling about catch-up immunizations. The workflow generally includes review of immunization history, evaluation of contraindications and precautions, shared decision-making about timing and type of vaccines, documentation of counseling content and time, and scheduling a follow-up visit or referral for vaccine administration at the clinic, pharmacy, or community vaccination site. Typical sites of service are outpatient clinic offices, preventive care clinics, school-based health centers, or telehealth encounters when permitted by payer policy.
