Non-pressure chronic ulcer of left calf w necrosis of muscle

This code signifies a persistent open sore on the lower leg, specifically the left calf, that is not caused by pressure. The ulceration has progressed to involve the underlying muscle tissue, indicating significant tissue death (necrosis) at this deep level. This condition is typically chronic, meaning it has been present for an extended period.

Apply this code when documentation clearly states a non-pressure chronic ulcer located on the left calf with confirmed necrosis extending into the muscle. This is often seen in patients with underlying vascular disease, diabetes, or other conditions that impair wound healing. Supporting documentation should include the location, chronicity, non-pressure etiology, and the depth of tissue involvement.

• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers.
• Verify the laterality (left calf) and the specific tissue depth (necrosis of muscle) are clearly documented.
• Always sequence this code after any underlying systemic conditions contributing to the ulcer, such as diabetes mellitus or peripheral artery disease.
