Osteolysis, right ankle and foot

This code signifies the pathological destruction or dissolution of bone tissue specifically located in the right ankle and/or foot. This process can lead to bone weakening, structural instability, and pain in the affected area. It represents a destructive bone lesion rather than a bone formation issue.

Apply this code when documentation clearly indicates osteolysis affecting the bones of the right ankle or foot. This diagnosis is often supported by imaging studies such as X-rays, CT scans, or MRI, which show areas of bone resorption or destruction. It is appropriate for conditions like inflammatory arthritis, tumors, or infections causing bone breakdown in this specific anatomical region.

• Ensure the documentation specifies "osteolysis" and not merely "bone lesion" without further clarification of bone destruction.
• Verify the laterality is explicitly stated as "right" for the ankle and/or foot.
• Consider sequencing this code after the underlying cause of the osteolysis, if known and documented (e.g., a specific type of arthritis or tumor).
