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

This code signifies a persistent open sore on the right lower leg, excluding the foot and ankle, that is not caused by pressure. The ulceration extends into the muscle tissue but does not exhibit any signs of tissue death. This condition typically arises from underlying vascular insufficiency, neuropathy, or systemic diseases.

Apply this code for patients presenting with a chronic, non-healing ulcer on the right lower leg where clinical examination and debridement confirm involvement of the muscle layer. Documentation should explicitly state the absence of necrosis and specify the right lower leg as the affected site. This code is appropriate when the etiology is not pressure-related.

• Ensure documentation clearly distinguishes between muscle involvement and bone involvement; a different code applies for bone involvement.
• Verify the absence of necrosis; if necrosis is present, a different code from the L97 series should be selected.
• Always sequence this code after any underlying systemic condition contributing to the ulcer (e.g., chronic venous insufficiency, diabetes mellitus with peripheral angiopathy).
