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

This code signifies a persistent, open sore on the left lower leg, excluding those caused by pressure, that extends into the muscle tissue. There is no indication of dead tissue (necrosis) within the ulcer.

Apply this code when documentation specifies a chronic, non-pressure ulcer on the left lower leg that has penetrated to the muscle layer. The medical record must explicitly state the absence of necrosis.

• Ensure documentation clearly differentiates between pressure and non-pressure ulcers.
• Verify the specific anatomical location on the left lower leg and the depth of tissue involvement (muscle).
• Confirm the absence of necrosis; if necrosis is present, a different code would be appropriate.
