Non-pressure chronic ulcer of chest with necrosis of muscle

This code signifies a persistent, non-pressure-related open sore on the chest wall that has progressed to involve the underlying muscle tissue, exhibiting signs of tissue death. It describes a severe, long-standing ulceration not caused by sustained pressure, with visible necrotic muscle.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer located on the chest, and a physician's assessment confirms necrosis extending into the muscle layer. This typically applies to ulcers resulting from trauma, infection, or vascular insufficiency, rather than decubitus.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify the ulcer's location is explicitly stated as "chest" and the depth of necrosis reaches "muscle."
• Code any associated underlying systemic conditions or infections contributing to the ulcer.
