Non-prs chronic ulcer of left hand with fat layer exposed

This code signifies a persistent open sore on the left hand that is not caused by pressure and has progressed to the point where subcutaneous fat is visible. This indicates a deeper ulceration, beyond the skin layers, often associated with underlying systemic conditions or poor circulation.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the left hand with exposed adipose tissue. This typically occurs in patients with conditions like diabetes, peripheral vascular disease, or venous insufficiency. Supporting documentation should include the location, chronicity, and depth of the ulcer.

• Ensure the documentation specifies "left hand" and "fat layer exposed" to accurately assign this code.
• Distinguish from pressure ulcers (L89.-) and acute ulcers, which are coded differently.
• Always code any underlying systemic condition (e.g., diabetes mellitus with complications) as a primary or secondary diagnosis.
