Non-prs chr ulcer of r calf with bone invl w/o evd of necr

This code signifies a persistent open sore on the right lower leg, specifically the calf, that is not caused by pressure. The ulceration extends deeply enough to affect the underlying bone, but there is no indication of dead tissue (necrosis) within the wound. This condition typically arises from venous insufficiency, arterial disease, or other systemic conditions.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the right calf with confirmed bone involvement. This is appropriate when imaging (e.g., X-ray, MRI) or surgical findings confirm osteomyelitis or direct bone exposure within the ulcer bed, and the absence of necrosis is explicitly noted.

• Confirm the laterality (right calf) and the specific anatomical site.
• Ensure documentation differentiates between bone involvement and mere deep tissue involvement; bone must be affected.
• Verify the absence of necrosis; if necrosis is present, a different subcategory code would be appropriate.
