Non-prs chr ulc of left calf with bone invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the left calf that extends down to and involves the bone. There is no indication of dead tissue (necrosis) within the ulcer. This condition often arises from underlying vascular insufficiency, neuropathy, or systemic diseases.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the left calf with confirmed bone involvement. The medical record must explicitly rule out necrosis. This code is appropriate for ulcers secondary to conditions like venous stasis, arterial insufficiency, or diabetic neuropathy, provided the bone is affected.

• Ensure documentation specifies "left calf" and "bone involvement" for accurate coding.
• Distinguish from ulcers with necrosis (L97.221-L97.223) or without bone involvement (L97.224-L97.225).
• Always sequence the underlying cause of the ulcer (e.g., chronic venous insufficiency, diabetes mellitus with complications) before this code.
