Osteolysis, right hand

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

Apply this code when documentation explicitly states osteolysis of the right hand. This can be observed in imaging reports (X-rays, MRI) or noted by the clinician as a finding in conditions such as tumors, infections, inflammatory processes, or metabolic disorders affecting the bone.

• Ensure the documentation specifies "osteolysis" and not just generalized osteoporosis or osteopenia.
• Verify the laterality is clearly documented as "right hand" to avoid miscoding.
• Always code the underlying cause of the osteolysis first, if known and documented.
