Non-pressure chronic ulcer of neck with fat layer exposed

This code signifies a persistent open sore on the neck that is not caused by pressure, where the subcutaneous fat tissue is visible within the ulcer bed. It indicates a significant tissue loss extending beyond the dermis into the adipose layer.

Apply this code for non-pressure ulcers located on the neck that have progressed to a stage where subcutaneous fat is exposed. Documentation must clearly state the ulcer's location on the neck, its non-pressure etiology, and the presence of exposed fat.

• Ensure documentation explicitly differentiates from pressure ulcers (L89.-).
• Verify the ulcer is chronic; acute ulcers would be coded differently.
• Confirm the anatomical site is specifically the neck, not the head or shoulder.
