    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 58-year-old male with chronic venous insufficiency and symptomatic lower-extremity edema who presents to a vascular clinic for management. After history and physical exam confirm venous stasis changes and measurable limb swelling, the vascular specialist or orthotist performs limb measurements and documents the medical necessity for gradient compression to reduce edema and improve venous return. The patient is fitted for a custom-made medium-weight graduated compression sleeve coded as S8422. Workflow includes: initial evaluation and measurement by a licensed clinician or certified orthotist, fabrication order with detailed measurements and justification, delivery and fitting appointment to confirm fit and function, patient education on wear schedule and skin care, and follow-up to assess efficacy and durability. Typical site of service is an outpatient vascular clinic, orthotics/prosthetics provider facility, or durable medical equipment supplier with a private fitting room. Patients often have prior conservative management (leg elevation, topical care) and may have wound care or referral to a vascular surgeon if underlying pathology requires intervention.
