Non-prs chronic ulcer of l forearm with fat layer exposed

This code describes a persistent, non-pressure-related open sore on the left forearm that has eroded through the epidermis and dermis, exposing the subcutaneous fat tissue. This indicates a deeper ulceration that has progressed beyond superficial skin layers.

Use this code for patients presenting with a chronic ulcer on the left forearm where the wound bed clearly shows adipose tissue. Documentation should specify the anatomical location (left forearm), the chronicity of the ulcer, and the depth of tissue involvement (fat layer exposed).

• Differentiate from pressure ulcers; this code is specifically for non-pressure etiology.
• Ensure documentation specifies "left forearm" and not just "arm" or "forearm."
• Verify the depth of tissue loss; codes exist for muscle, bone, or unspecified depth.
