Non-prs chr ulc unsp prt unsp lw leg w msl invl w/o evd necr

This code signifies a chronic, non-pressure-related open sore on an unspecified part of an unspecified lower leg, extending into the muscle tissue. There is no evidence of tissue death (necrosis) associated with this ulcer.

Apply this code when documentation specifies a chronic lower leg ulcer that is not caused by pressure, involves muscle, and the specific location on the lower leg or laterality is not documented. This code is appropriate when the provider explicitly states the absence of necrosis.

• Ensure the documentation clearly states "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify that the ulcer extends to the muscle layer and that necrosis is explicitly ruled out.
• Avoid using this code if a more specific anatomical location (e.g., ankle, calf) or laterality (left/right) is documented; instead, use a more precise L97 subcategory.
