Clinical & Coding Specifications
Clinical Context
A patient with chronic venous insufficiency and significant lower extremity edema presents to a durable medical equipment (DME) clinic after evaluation by a vascular specialist.

The workflow includes: outpatient evaluation by a physician or certified lymphedema therapist; measurements of limb circumference and length; fabrication order submitted to a certified orthotics/ prosthetics or compression garment vendor; fitting appointment for the custom sleeve; patient education on wear schedule and skin care; follow-up visits for fit adjustments and assessment of skin integrity and symptomatic response. Typical site of service is an outpatient clinic, specialty vascular or lymphedema clinic, or a DME supplier's fitting center. The device S8423 is dispensed and documented in the medical record with diagnosis linkage and any applicable modifier for laterality or circumstance of service.
