Osteolysis, left hand

This code signifies the pathological destruction or dissolution of bone tissue specifically occurring in the left hand. It indicates a loss of bone density and structure, which can result from various underlying conditions.

Apply this code when documentation explicitly states osteolysis affecting the left hand. This includes conditions like inflammatory arthritis, tumors, infections, or metabolic disorders causing bone resorption in this specific anatomical site. Supporting documentation should detail the location and nature of the bone loss.

• Always confirm the laterality (left hand) is clearly documented.
• Code an underlying cause of the osteolysis if known and documented (e.g., specific arthritis, tumor).
• Distinguish from osteoporosis (generalized bone density loss) or osteopenia (reduced bone mass) unless the documentation specifies localized osteolysis.
