Non-prs chronic ulcer of right thigh limited to brkdwn skin

This code signifies a persistent open sore on the right thigh that is not caused by pressure. The ulceration is superficial, affecting only the epidermal and dermal layers of the skin, without extending into subcutaneous tissue, muscle, or bone.

Use this code for documented chronic ulcers on the right thigh where the etiology is not pressure-related (e.g., venous stasis, arterial insufficiency, diabetic neuropathy, vasculitis). Documentation should clearly state the location (right thigh), chronicity, and confirm that the ulceration is limited to skin breakdown.

• Ensure documentation specifies "right thigh" and explicitly states the ulcer is non-pressure related.
• Distinguish from pressure ulcers (L89.-) and ulcers with deeper tissue involvement (which would require a different 6th character).
• Always code the underlying cause of the ulcer (e.g., venous insufficiency, diabetes) as an additional diagnosis.
