Billing Code Overview

HCPCS Level II code E1635 describes a compact (portable) travel hemodialyzer system. This code applies to a medical device designed to provide hemodialysis treatment in a portable format intended for travel or transportable use. The service type is the provision and use of a portable hemodialyzer device to deliver dialysis therapy. The typical site of service is non-facility, including patient residences, temporary lodging, or other community settings where travel or portability is required.

Clinical & Coding Specifications

Clinical Context

A 62-year-old patient with end-stage renal disease (ESRD) receiving maintenance hemodialysis requires a compact travel hemodialyzer system for short-term use while traveling away from their home dialysis center. The patient has a stable arteriovenous fistula and usual dialysis prescription of thrice-weekly treatments. The nephrology clinic coordinates a portable hemodialysis device rental or supply shipment to a lodging facility or temporary residence. A dialysis nurse or trained technician delivers and sets up the compact system, verifies vascular access function, programs the prescribed blood and dialysate flow rates, conducts a pre-treatment safety check, and supervises or performs the treatment according to the patient’s usual prescription. On completion, the device is cleaned or disposed per manufacturer instructions and the patient returns to their home dialysis schedule. Typical site of service is outpatient or non-facility settings such as hotel, private residence, or transit locations where a compact travel hemodialyzer system enables continuity of prescribed hemodialysis treatments.
