Other osteonecrosis, right shoulder

This code signifies the death of bone tissue in the right shoulder due to insufficient blood supply, not otherwise specified as a more common type of osteonecrosis. This condition can lead to pain, joint collapse, and functional impairment of the shoulder.

Apply this code when documentation specifies osteonecrosis of the right shoulder and does not identify a more specific type (e.g., avascular necrosis due to trauma, steroid-induced). Supporting documentation should include imaging reports (X-ray, MRI) confirming osteonecrosis and a physician's diagnosis.

• Ensure laterality is clearly documented as "right shoulder."
• Do not use if a more specific type of osteonecrosis (e.g., post-traumatic, steroid-induced) is identified; use the appropriate specific code.
• Code any associated pathological fractures separately if present.
