Non-pressure chronic ulcer of abdomen with necrosis of bone

This code signifies a persistent, non-pressure-related open sore located on the abdominal wall that has progressed to involve the underlying bone tissue, indicating significant tissue death. It describes a severe stage of ulceration where the necrotic process extends beyond soft tissues into the osseous structure.

Use this code for patients presenting with a chronic, non-decubitus ulcer on the abdomen where diagnostic imaging (e.g., X-ray, MRI) or surgical debridement confirms bone involvement and necrosis. Documentation must clearly specify the abdominal location, chronicity, non-pressure etiology, and the presence of bone necrosis.

• Ensure documentation explicitly states "non-pressure" etiology to differentiate from pressure ulcers.
• Verify the anatomical site is specifically "abdomen"; do not use for ulcers on other body parts.
• Confirm the presence of "necrosis of bone" through provider notes or pathology reports; mere bone exposure is insufficient.
