Summary & Overview
HCPCS G9265: Maintenance Hemodialysis with Catheter Access ≥90 Days
HCPCS Level II code G9265 denotes a patient receiving maintenance hemodialysis for 90 days or longer with a catheter as the vascular access. Nationally, this code flags a specific chronic dialysis population using catheter access, which has implications for care coordination, infection risk monitoring, and facility resource use. The code is relevant for outpatient dialysis centers and hospital outpatient departments that bill for ongoing dialysis services.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what the code represents, payer coverage context, and the clinical setting where the service is provided. The publication reviews typical billing considerations, common modifiers associated with dialysis-related services (listed separately), and where this code fits in clinical workflows.
This report provides a concise clinical and billing context for G9265, explains why identification of catheter-dependent maintenance dialysis patients matters for quality and cost monitoring, and outlines the types of benchmarks and policy updates readers can expect to find in the full publication.

Billing Code Overview
HCPCS Level II code G9265 represents a patient receiving maintenance hemodialysis for greater than or equal to 90 days with a catheter as the mode of vascular access. This service describes ongoing outpatient dialysis care for a patient whose vascular access is a catheter and who has been on maintenance hemodialysis for 90 days or more.
-
Service type: Maintenance hemodialysis (outpatient dialysis care)
-
Typical site of service: Outpatient dialysis center or hospital outpatient department

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease (ESRD) has received maintenance hemodialysis via a tunneled central venous catheter for at least 90 days. The patient attends thrice-weekly outpatient dialysis sessions at a dialysis center; nursing staff verify catheter function, perform routine catheter site care, and document dialysis adequacy and vascular access status each visit. The clinical workflow includes pre-dialysis assessment (vital signs, weight, review of access), catheter dressing change and exit-site inspection as indicated, intradialytic monitoring for complications (bleeding, infection, thrombosis, inadequate flows), and coordination with the nephrology team for plans to convert to an arteriovenous fistula or graft when possible. If catheter dysfunction, infection, or other complications arise, the outpatient dialysis nurse and nephrologist arrange imaging, line exchange, antibiotic therapy, or referral for vascular surgery or interventional radiology. Billing for the maintenance dialysis encounter documents the duration of dialysis dependence, the catheter as the vascular access, and any concurrent services or modifiers reflecting unusual circumstances or multiple payors.
