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

This code signifies a persistent, non-pressure-related open sore on an unspecified hand, where the ulceration extends through the dermis and subcutaneous tissue, exposing the underlying adipose (fat) layer. It indicates a deep tissue loss not caused by sustained pressure.

Use this code when documentation specifies a chronic, non-decubitus ulcer located on the hand, and the wound depth clearly indicates exposure of subcutaneous fat. This typically applies to conditions like venous stasis ulcers, arterial ulcers, or neuropathic ulcers affecting the hand, provided the depth criteria are met.

• Ensure documentation explicitly states "chronic" and "non-pressure" to differentiate from acute ulcers or pressure injuries.
• Verify the ulcer location is "hand" and the depth specifies "fat layer exposed"; avoid using for muscle or bone exposure.
• Always code any underlying systemic condition (e.g., diabetes, peripheral vascular disease) as a primary or secondary diagnosis.
