Non-prs chr ulc unsp heel/midft w msl invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on an unspecified heel or midfoot that extends into the muscle tissue. There is no indication of tissue death (necrosis) associated with the ulcer. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation specifies a chronic, non-pressure ulcer of the heel or midfoot, with the depth clearly reaching muscle, and explicitly states the absence of necrosis. This is appropriate for ulcers not caused by sustained pressure, such as diabetic foot ulcers or venous stasis ulcers affecting these areas.

• Ensure documentation specifies "non-pressure" and the ulcer's depth reaching "muscle."
• Verify the absence of necrosis; if present, a different code would be required.
• Laterality (left/right) is unspecified with this code; if known, a more specific code should be used.
