G9279 Pneumococcal Screening HCPCS Reimbursement | OpenPayer

Summary & Overview

HCPCS G9279: Pneumococcal Screening and Vaccination Documented Prior to Discharge

HCPCS Level II code G9279 denotes a pneumococcal screening performed with documented evidence that the patient received pneumococcal vaccination prior to discharge. This preventive service code captures an important quality and safety step in inpatient or facility care, ensuring patients have been screened and vaccinated against pneumococcal disease before leaving a care setting. Nationally, such documentation supports vaccine uptake, discharge safety practices, and alignment with public health goals for adult immunizations.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what G9279 represents, the clinical and operational context for use at discharge, typical sites of service, and the types of benchmarks and policy considerations commonly associated with immunization documentation codes. The content highlights areas readers can expect to learn about, including coding intent, common use cases in inpatient and facility discharge workflows, and where documentation typically resides in the medical record. Data not available in the input will be identified as such where relevant.

Billing Code Overview

HCPCS Level II code G9279 documents that pneumococcal screening was performed and that vaccination was received prior to discharge. This code represents a preventive care action centered on assessing patients for prior pneumococcal immunization and recording that vaccination status before the patient leaves the facility.

Service type: Pneumococcal screening and documentation of vaccination prior to discharge
Typical site of service: Inpatient hospital or facility discharge setting where vaccination status is assessed and recorded before patient discharge

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult inpatient admitted for an acute medical condition (for example, congestive heart failure exacerbation or community-acquired pneumonia) who has unclear or incomplete pneumococcal vaccination history on admission. Prior to planned discharge, nursing or the inpatient medical team performs a documented pneumococcal screening: review of vaccination records, immunization registry query, and direct patient/caregiver interview to confirm prior receipt of pneumococcal vaccine(s). If the patient reports prior vaccination, the team documents vaccine type(s) and dates in the chart; if the patient is unvaccinated or vaccination history is unknown and clinically appropriate, vaccination may be administered before discharge. Documentation elements include evidence of screening, vaccine receipt prior to discharge (vaccine type and date), medical decision-making about vaccination contraindications, and any refusal. This workflow typically occurs on the inpatient ward, observation unit, or swing bed prior to hospital discharge and involves inpatient nursing, hospitalists or primary inpatient provider, and pharmacy/immunization services for vaccine administration and documentation in the medical record and immunization information systems.
