Summary & Overview
HCPCS G0458: Low Dose Rate Prostate Brachytherapy, Composite Rate
HCPCS Level II code G0458 designates a composite-rate payment for low dose rate (LDR) prostate brachytherapy services. The code bundles procedural and facility components for LDR prostate seed implantation and related care, reflecting a single payment for the complete brachytherapy episode rather than itemized charges. Nationally, this code matters because brachytherapy remains a standard curative option for localized prostate cancer, and composite-rate coding affects billing workflows, payer contract terms, and facility revenue recognition.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for LDR prostate brachytherapy, the billing implications of a composite-rate HCPCS code, and typical site-of-service considerations. The publication summarizes benchmark considerations where available, highlights policy and reimbursement updates relevant to composite-rate brachytherapy coding, and outlines common billing modifiers and payer-specific adjudication factors when present.
This national summary is intended for revenue cycle managers, clinical coders, and policy analysts seeking a concise reference on HCPCS Level II code G0458, its clinical application, and the billing environment for LDR prostate brachytherapy.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old man with clinically localized prostate cancer (e.g., low- or intermediate-risk disease) referred to radiation oncology for definitive low dose rate prostate brachytherapy. The clinical workflow begins with a consult visit documenting prostate cancer staging, PSA, Gleason score, and patient comorbidities. Pre-procedure planning includes TRUS (transrectal ultrasound) or MRI-based volume assessment and a brachytherapy treatment plan created by the radiation oncologist and medical physicist. On the day of service the patient is taken to an operating or procedure room (often ambulatory surgery center or hospital outpatient department) under monitored anesthesia care or general anesthesia. The radiation oncologist implants radioactive seeds (commonly iodine-125 or palladium-103) into the prostate using ultrasound or fluoroscopic guidance; the composite rate G0458 covers the bundled LDR prostate brachytherapy service. Intraoperative dosimetry and device handling are coordinated with the medical physicist and radiation safety officers. Postprocedure recovery includes monitoring in the PACU, discharge instructions, and scheduling of follow-up visits for PSA monitoring, urinary symptom assessment, and potential management of acute urinary retention or radiation-related side effects. Typical site of service is an ambulatory surgery center, hospital outpatient department, or radiation oncology procedure suite.
