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

This code signifies a persistent open sore on the calf, not caused by pressure, that has progressed to involve the underlying bone. There is no indication of dead tissue (necrosis) within the ulcer or surrounding area. This typically represents a severe, long-standing ulceration.

Use this code when documentation specifies a chronic, non-pressure ulcer located on an unspecified calf that has extended to the bone. The medical record must explicitly state the absence of necrosis. This code is appropriate for ulcers resulting from conditions like venous insufficiency, arterial disease, or neuropathy, where bone involvement is confirmed.

• Ensure documentation clearly distinguishes between pressure and non-pressure ulcers.
• Verify the specific anatomical location (calf) and confirm bone involvement without necrosis.
• Always sequence this code after the underlying cause of the ulcer (e.g., chronic venous insufficiency, diabetic neuropathy).
