Summary & Overview
HCPCS G9415: Missed Meningococcal Vaccine Dose, Ages 10–13
HCPCS Level II code G9415 documents a missed dose of meningococcal vaccine for patients who did not receive one dose of serogroups A, C, W, Y (or A, C, W, Y, B) between their 10th and 13th birthdays. Nationally, accurate coding of missed adolescent immunizations supports public health surveillance, school-entry requirements, and targeted outreach to improve vaccination coverage. Clear documentation also affects preventive care workflows and quality reporting.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code's clinical context, typical sites of service, and what the code signifies for immunization status tracking. The publication outlines common reporting contexts, relevant quality and population health implications, and benchmarking considerations where available. When payer-specific coverage or billing guidance is not provided in the input, the report notes that data are not available.
This summary is intended for clinicians, billing professionals, and health system administrators seeking a national overview of HCPCS Level II code G9415, its role in documenting missed adolescent meningococcal vaccination, and the operational implications for outpatient and public health settings.

Clinical & Coding Specifications
Clinical Context
A 12-year-old adolescent presents to a primary care pediatric clinic for a routine well-child visit and immunization review. During the visit the clinician reviews the immunization record and identifies that the patient did not receive a dose of meningococcal conjugate vaccine covering serogroups A, C, W, Y (MenACWY) between the 10th and 13th birthdays as recommended. The clinician documents vaccine history, discusses vaccine benefits and risks with the parent/legal guardian, obtains informed consent, and administers the indicated meningococcal vaccine per the immunization schedule. The immunization is recorded in the electronic health record and state immunization registry, and billing staff assign the preventive visit and vaccine administration codes. If the patient declines or a medical contraindication is identified, the visit is documented accordingly and an appropriate preventive or counseling code may be billed without the vaccine. Typical sites of service include outpatient primary care clinics, pediatric offices, school-located health centers, community health centers, and public health clinics.
