Non-prs chr ulc oth prt l foot with msl invl w/o evd of necr

This code signifies a persistent open sore on a part of the left foot, excluding pressure ulcers, that has progressed to involve the muscle tissue. There is no indication of tissue death (necrosis) in the affected area. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the left foot, with clear involvement of the muscle layer. The physician's notes must explicitly state the absence of necrosis. This code is appropriate for conditions like diabetic foot ulcers or venous stasis ulcers that have deepened to muscle.

• Ensure documentation specifies "other part of left foot" to differentiate from heel, midfoot, or ankle.
• Verify the ulcer is explicitly stated as "non-pressure" and "chronic."
• Confirm the absence of necrosis; if present, a different code indicating necrosis would be required.
