Non-prs chronic ulcer skin/ sites limited to brkdwn skin

This code signifies a persistent skin ulceration, not caused by pressure, occurring on areas of the body other than those specified by more granular codes (e.g., lower extremities, trunk). The ulcer is characterized by a breakdown of the skin layers, indicating a chronic wound that has failed to heal within an expected timeframe.

Apply this code for chronic non-pressure ulcers located on sites such as the scalp, neck, upper extremities (excluding hands/feet), or buttocks, where the documentation explicitly states "skin breakdown" without further specification of depth. This code is appropriate when the ulcer is clearly documented as chronic and not a result of pressure.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute ulcers or pressure ulcers.
• Verify the anatomical site is not more specifically covered by other L97 or L98.4x codes (e.g., lower extremity, sacrum).
• If the ulcer extends beyond skin breakdown to involve muscle or bone, a more specific code indicating the depth of the ulcer should be used.
