Summary & Overview
HCPCS G6007: Radiation Treatment Delivery to Two Areas with Multiple Blocks
HCPCS Level II code G6007 represents a specific external beam radiation therapy delivery service: treatment to two separate treatment areas with three or more ports on a single area and the use of multiple blocks, delivered at energies up to 5 MeV. This technical code captures a defined radiation delivery setup and is relevant for billing and clinical documentation in radiation oncology nationwide. Nationally, precise use of procedure codes like G6007 affects provider reimbursement, treatment encounter classification, and consistency in radiation therapy reporting.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings tied to G6007, plus guidance on where this code sits within common radiation oncology billing workflows. The publication summarizes benchmarks and policy-relevant considerations such as proper service-line classification and typical sites of service. It also highlights where input data was not available and which related billing elements require local payer or institutional reference for claim adjudication. The goal is to provide a practical, national-level briefing on the code’s meaning, typical use, and the payer landscape that commonly adjudicates claims for this radiation delivery service.
Billing Code Overview
HCPCS Level II code G6007 describes radiation treatment delivery for two separate treatment areas, where one treatment area uses three or more ports and multiple blocks are employed. The service description specifies delivery up to 5 megavolts (MeV).
-
Service type: External beam radiation therapy delivery involving multiple treatment areas and beam ports
-
Typical site of service: Radiation oncology department or hospital outpatient radiation therapy unit
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a history of non-small cell lung cancer presents for external beam radiation therapy targeting two distinct treatment areas: a primary left upper lobe tumor and a separate ipsilateral hilar nodal basin. The treatment plan uses megavoltage photons up to 5 megavolts with multiple custom or multileaf collimator blocks and three or more beam ports directed to the primary treatment area. The radiation therapist documents setup, verification imaging, and delivery of daily fractions to both target areas during a single treatment session. The clinical workflow includes consultation with the radiation oncologist, simulation with CT-based planning, creation of blocks or MLC patterns for dose shaping, treatment planning and dosimetry review, daily image guidance as required, and delivery of radiation fields to both treatment sites in one visit billed under G6007 for delivery to two separate treatment areas with multiple blocks and three or more ports on a single area.
