Other secondary osteonecrosis, right shoulder

This code signifies the death of bone tissue in the right shoulder due to a secondary cause, meaning it's a consequence of another underlying condition or treatment rather than a primary, idiopathic event. This condition leads to bone collapse and joint destruction if untreated.

Apply this code when documentation clearly indicates osteonecrosis of the right shoulder that is secondary to conditions such as long-term corticosteroid use, trauma, systemic lupus erythematosus, or sickle cell disease. Ensure the laterality (right shoulder) is explicitly stated.

• Always identify and code the underlying secondary cause of the osteonecrosis first, if known and not already resolved.
• Differentiate carefully between primary (idiopathic) and secondary osteonecrosis; codes for idiopathic forms are distinct.
• Verify documentation specifies "right shoulder" to avoid laterality errors; codes exist for left, bilateral, and unspecified shoulders.
