Non-prs chronic ulcer oth prt left foot w fat layer exposed

This code signifies a persistent, open sore on the left foot, excluding the heel or toes, that is not caused by pressure. The ulceration has progressed to a depth where the subcutaneous fat layer is visible. This indicates a significant tissue loss beyond the epidermis and dermis.

Use this code when documentation clearly states a chronic, non-pressure ulcer on the left foot (e.g., dorsum, plantar aspect excluding heel/toes, or malleolus) and explicitly mentions exposure of the fat layer. This applies to conditions such as venous stasis ulcers, arterial ulcers, or diabetic ulcers that have reached this specific depth.

• Ensure the documentation specifies "left foot" and "other part" to differentiate from heel or toe ulcers.
• Verify the ulcer is explicitly stated as "non-pressure" and "chronic."
• Confirm the depth of the ulcer is documented as "fat layer exposed" or equivalent (e.g., subcutaneous tissue visible).
