Non-prs chronic ulcer of right thigh w fat layer exposed

This code signifies a persistent, non-pressure-related open sore on the right thigh that has eroded through the skin and subcutaneous tissue, exposing the underlying adipose layer. This type of ulcer is typically slow to heal and may be associated with underlying vascular insufficiency, neuropathy, or other systemic conditions.

Apply this code when documentation clearly indicates a chronic, non-decubitus ulcer located specifically on the patient's right thigh, with the depth of tissue loss reaching the fat layer. Supporting documentation should specify chronicity, location, and the exposed tissue layer.

• Ensure the documentation explicitly states "right thigh" and "fat layer exposed" to accurately assign this specific code.
• Differentiate from pressure ulcers (L89.-) and acute ulcers, which have different coding pathways.
• Always code any underlying systemic conditions (e.g., diabetes mellitus, peripheral vascular disease) that contribute to the ulcer formation as additional diagnoses.
