Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with chronic venous insufficiency, venous stasis ulcer, or significant lower-extremity edema who requires gradient compression bandaging as part of wound care or edema management. In a wound clinic, long‑term care facility, or home health visit, a licensed clinician (wound care nurse, home health nurse, or vascular specialist) measures the limb and cuts conforming gauze bandage supplied per linear yard to the required length. The clinician applies multilayer gradient compression bandaging from the distal foot/ankle progressing proximally to achieve graduated pressure (highest at the ankle, decreasing proximally), secures dressing layers, and documents the amount of A6596 used in linear yards. Typical workflow includes evaluation of circulation and sensation, cleansing and dressing the wound if present, application of short‑stretch or conforming gauze with appropriate padding, patient/caregiver education on signs of ischemia or worsening infection, and scheduling follow‑up for rewrap or dressing change. Supplies billed with A6596 are reported per linear yard for each unit used during the visit.
