Non-prs chronic ulcer of right ankle w necrosis of muscle

This code signifies a persistent, open sore on the right ankle that is not caused by pressure, and where there is evidence of dead muscle tissue. This indicates a severe stage of ulceration, often associated with underlying vascular insufficiency, neuropathy, or systemic disease.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the right ankle, specifically noting the presence of muscle necrosis. This typically occurs in patients with advanced peripheral arterial disease, diabetic foot ulcers, or venous stasis ulcers that have progressed to deep tissue involvement.

• Ensure documentation explicitly states "non-pressure" to differentiate from pressure ulcers.
• Verify the laterality (right ankle) and the specific tissue depth (muscle necrosis) are clearly documented.
• Always sequence this code after any underlying systemic condition (e.g., diabetes mellitus with complications, peripheral vascular disease) that contributed to the ulcer development.
