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

This code signifies a persistent, open sore on the left lower leg, excluding pressure ulcers, that has progressed to involve the underlying bone. There is no indication of dead tissue (necrosis) within the ulcer or surrounding area. This condition typically results from poor circulation, diabetes, or other systemic diseases.

Apply this code when documentation clearly states a chronic ulcer on the left lower leg, specifies involvement of bone, and explicitly denies the presence of necrosis. This is appropriate for non-healing wounds that have penetrated deep tissue layers. Supporting documentation would include imaging reports confirming bone involvement and physician notes detailing the ulcer's chronicity and lack of necrosis.

• Always verify laterality (left vs. right) and the specific anatomical site on the lower leg.
• Ensure documentation explicitly states "bone involvement" and "without necrosis" to avoid miscoding.
• Differentiate carefully from pressure ulcers (L89.-) and ulcers with necrosis (L97.823, L97.824).
