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

This code signifies a persistent, non-pressure-related open sore located on the left heel or midfoot that extends into the muscle tissue. There is no indication of dead tissue (necrosis) present within the ulcer.

Apply this code when documentation specifies a chronic ulcer on the left heel or midfoot, clearly stating it is not pressure-induced and involves muscle. The physician's notes should explicitly exclude any mention of necrotic tissue.

• Ensure the documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the ulcer depth reaches muscle, but not bone, and that necrosis is absent.
• Always code the underlying cause of the ulcer (e.g., diabetes, peripheral vascular disease) first.
