Summary & Overview
HCPCS G0563: SBRT Delivery with PET-Guided Real-Time Adjustments, Up to 5 Fractions
HCPCS Level II code G0563 represents stereotactic body radiation therapy (SBRT) treatment delivery per fraction for one or more lesions, incorporating image guidance and real-time positron emission–based delivery adjustments, with the entire course limited to five fractions. This code captures a high-precision radiation delivery service used in oncology care and is significant for payers and providers managing advanced cancer treatments that rely on PET-guided targeting to improve accuracy and spare normal tissue.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for SBRT with PET-based adjustments, typical sites of service, and the service definition tied to the five-fraction course limit. The publication outlines common billing considerations and commonly reported modifiers (provided in the input), and it summarizes reimbursement and coverage themes across major national payers. Additionally, the report highlights where input data is incomplete and lists items marked as unavailable.
This summary is intended for national audiences including payers, hospital and clinic billing teams, and oncology service line managers who need a concise reference to what HCPCS Level II code G0563 denotes, how it is used in practice, and which payers are typically involved.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a solitary pulmonary metastasis from a previously resected colorectal carcinoma is referred for stereotactic body radiation therapy (SBRT). The multidisciplinary tumor board has recommended ablative radiotherapy as the patient is medically inoperable due to cardiopulmonary comorbidity. Simulation with 4D-CT and PET/CT fusion is performed to account for respiratory motion and to visualize metabolically active tumor. A stereotactic treatment plan is generated prescribing a high biologically effective dose delivered in up to five fractions. On each treatment day the patient is positioned in an immobilization device, image-guidance (cone beam CT and real-time PET-based guidance) is used to localize the target, and delivery is performed with motion management and real-time positron emission–based adjustments. Documentation includes diagnosis, simulation and planning notes, image-guidance verification, fraction number, and total fractions (not to exceed five). The clinical workflow involves radiation oncology consult, simulation, treatment planning, physics QA, daily image-guided SBRT delivery with on-table adjustments, and follow-up for response and toxicity assessment.
