Summary & Overview
HCPCS G2157: Pneumococcal Vaccine Sequence, Age 60+
HCPCS Level II code G2157 documents a completed adult pneumococcal vaccination sequence in which a patient received the 13-valent pneumococcal conjugate vaccine followed by the 23-valent pneumococcal polysaccharide vaccine at least 12 months later, with the initial dose administered after age 60. This code matters nationally as it captures adherence to pneumococcal vaccination schedules for older adults, a population at higher risk for invasive pneumococcal disease and related complications.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how the code is used to represent vaccine sequencing for adults, the typical clinical and service settings where it is billed, and which payers commonly recognize the code. The publication also summarizes benchmark perspectives and policy-relevant context for adult immunization coding and reporting.
The report provides concise benchmarks, notes of recent policy updates that affect adult immunization documentation and billing, and clinical context about the importance of sequential pneumococcal vaccination after age 60. Data limitations and any missing elements from the input are noted where applicable.
Billing Code Overview
HCPCS Level II code G2157 indicates that a patient received both the 13-valent pneumococcal conjugate vaccine and the 23-valent pneumococcal polysaccharide vaccine at least 12 months apart, with the first occurrence after the age of 60 before or during the measurement period.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient presents to a primary care clinic for routine preventive care. Their immunization record shows prior receipt of the 13-valent pneumococcal conjugate vaccine (PCV13) at age 61. During the visit the clinician documents that at least 12 months have elapsed since the PCV13 dose. The clinician administers the 23-valent pneumococcal polysaccharide vaccine (PPSV23) during the same visit to complete recommended pneumococcal vaccination sequencing for older adults. The clinical workflow includes verifying prior vaccine dates in the electronic medical record or immunization registry, confirming patient consent and medical history for contraindications or precautions, performing vaccine administration (intramuscular or subcutaneous per product labeling), documenting lot number, manufacturer, administration site and date, and coding the encounter with the appropriate HCPCS Level II code G2157 for reporting that the patient received both PCV13 and PPSV23 at least 12 months apart with the first dose after age 60. Typical sites of service include ambulatory primary care clinics, geriatric clinics, community health centers, and outpatient pharmacy immunization clinics. Typical patient scenario: an older adult with routine preventive visit, no acute illness, no contraindications to vaccination, and with documented prior PCV13 given more than 12 months prior; PPSV23 is administered and documented during the visit.
