Non-prs chr ulcer of left heel and midfoot w necros muscle

This code signifies a persistent, open sore on the left heel or midfoot that is not caused by pressure. The ulceration has progressed to involve the muscle tissue, indicating significant tissue damage and potential for deep infection. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the left heel or midfoot, and specifically mentions necrosis extending into the muscle layer. This typically applies to patients with advanced peripheral arterial disease, diabetic foot ulcers, or other conditions leading to severe tissue breakdown.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the exact anatomical location (left heel and midfoot) and the depth of tissue involvement (necrosis of muscle).
• Always code underlying conditions (e.g., diabetes mellitus with complications, peripheral artery disease) first, as they are often the etiology.
