Other osteonecrosis, unspecified shoulder

This code signifies the death of bone tissue in an unspecified shoulder joint due to a lack of blood supply, not otherwise specified as aseptic or due to trauma. It represents a form of osteonecrosis affecting the humeral head or glenoid, where the specific cause or type is not documented.

Use this code when documentation clearly indicates osteonecrosis of the shoulder, but the specific type (e.g., aseptic, post-traumatic) is not identified, and the affected shoulder (left or right) is also not specified. This code is appropriate when the physician's diagnosis is simply "osteonecrosis of shoulder, NOS."

• Avoid using this code if the laterality (left or right shoulder) is documented; instead, use the more specific M87.811 or M87.812.
• Do not use if the specific type of osteonecrosis (e.g., aseptic, post-traumatic) is known; refer to other codes within the M87 category.
• Always query the provider for laterality and specific type of osteonecrosis if not clearly documented to allow for more precise coding.
