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

This code signifies a persistent, non-pressure-related open sore located on an unspecified heel or midfoot, characterized by the presence of dead muscle tissue. This indicates a severe stage of ulceration, extending beyond the skin and subcutaneous tissue into the underlying muscle.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the heel or midfoot, and specifically notes muscle necrosis. This is appropriate for conditions like diabetic foot ulcers or venous stasis ulcers that have progressed to involve muscle death. Supporting documentation should include wound assessment details, location, chronicity, and the depth of tissue involvement.

• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers.
• Verify the ulcer location is specifically the heel or midfoot; avoid using for other foot locations.
• Confirm the presence of "necrosis of muscle" as this specifies the highest level of tissue destruction for this code.
