HCPCS Level II code G0252 designates PET imaging using full- and partial-ring scanners for the initial diagnosis and surgical planning of breast cancer, including tasks such as initial axillary lymph node staging. Nationally, this imaging modality supports clinical decision-making by refining staging, guiding surgical approaches, and informing multidisciplinary care planning for patients with suspected or newly diagnosed breast cancer.

Key payers considered in this context include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of what the code covers, typical sites of service, and payer applicability. The publication summarizes clinical context for PET use in breast cancer, outlines common billing considerations, and highlights available benchmarks and policy updates where applicable. It also identifies service-line implications for radiology and oncology providers, and operational considerations for scheduling and site-of-service selection.

This summary is intended for a national audience and focuses on the code’s clinical role, billing classification, and areas where organizations typically seek clarity when submitting claims for initial diagnostic PET imaging and preoperative staging in breast cancer care.
