HCPCS Level II code G0402 represents the Initial Preventive Physical Examination — a face-to-face visit delivered to new Medicare beneficiaries within their first 12 months of enrollment. Nationally, this code matters because it supports early preventive assessment and care planning for a high-risk population segment, and it is tied to Medicare coverage policies that shape provider workflows and billing practices. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn what the code represents clinically, which payers commonly encounter it, and the policy and billing context that influences its use. The publication provides benchmarks and operational guidance on claim categorization and expected sites of service, summarizes relevant policy updates affecting preventive visit coverage, and explains how G0402 fits within broader preventive care workflows. Data not available in the input is noted where applicable. The write-up is intended for national audiences including billing managers, policy analysts, and clinicians responsible for preventive care workflows and Medicare enrollment-period services.
