Non-pressure chronic ulcer of groin with fat layer exposed

This code signifies a persistent, non-pressure-related open sore located in the groin region where the subcutaneous fat tissue is visible. It indicates a full-thickness skin defect extending beyond the dermis into the adipose layer, without evidence of pressure as the causative factor.

Apply this code when documentation clearly states a chronic ulcer in the groin area and specifies that the fat layer is exposed. This is appropriate for ulcers resulting from conditions like venous insufficiency, arterial insufficiency, or neuropathic causes, but not from sustained pressure. Documentation should explicitly exclude pressure as the etiology and confirm the depth of tissue involvement.

• Always confirm the ulcer's etiology is non-pressure to differentiate from pressure ulcers.
• Ensure documentation specifies "groin" as the anatomical site and "fat layer exposed" for depth.
• Code an underlying condition (e.g., venous insufficiency, diabetes) as a primary diagnosis if it is the cause of the ulcer.
