Other osteonecrosis, left shoulder

This code signifies the death of bone tissue in the left shoulder joint due to a loss of blood supply, not otherwise specified as spontaneous or due to trauma, drugs, or prior disease. This condition can lead to pain, joint collapse, and arthritis.

Apply this code when documentation specifies osteonecrosis of the left shoulder and does not provide further specificity regarding the etiology (e.g., idiopathic, post-traumatic, drug-induced, or associated with caisson disease). This code is appropriate when the physician's diagnosis is "other osteonecrosis of the left shoulder" or "avascular necrosis of the left shoulder, unspecified."

• Ensure laterality is clearly documented as "left shoulder."
• Avoid using this code if a more specific etiology for the osteonecrosis is documented (e.g., M87.112 for drug-induced).
• Code any associated pain or functional limitations separately if documented.
