Clinical & Coding Specifications
Clinical Context
A patient presents with symptomatic upper‑extremity lymphedema and soft‑tissue swelling following axillary lymph node dissection for breast cancer. The patient is evaluated in an outpatient durable medical equipment (DME) clinic by an occupational therapist or certified lymphedema therapist who documents persistent limb swelling, risk of skin breakdown, and functional impairment despite conservative measures (elevation, manual lymphatic drainage, and short‑stretch bandaging). A custom gradient compression wrap with adjustable straps is ordered and fabricated to provide graduated compression for the arm; the device is measured and fitted in the clinic, with patient education on donning, doffing, cleaning, and wearing schedule. Follow‑up visits occur for sizing adjustments and to assess skin integrity and therapeutic response. Typical site of service is outpatient DME supplier or ambulatory clinic (occupational/physical therapy or lymphedema clinic).
