Other osteonecrosis, right humerus

This code signifies the death of bone tissue in the right upper arm bone (humerus) due to a loss of blood supply, not otherwise specified as a specific type of osteonecrosis. This condition can lead to bone collapse and joint destruction.

Apply this code when documentation specifies osteonecrosis of the right humerus, and the specific cause or type (e.g., steroid-induced, post-traumatic) is not identified or is categorized as "other." Supporting documentation should clearly indicate the anatomical site and the diagnosis of osteonecrosis.

• Ensure the documentation specifies "right humerus" as the affected site.
• Differentiate from M87.0xx codes (idiopathic osteonecrosis) and M87.1xx codes (drug-induced osteonecrosis) if a more specific cause is known.
• Consider sequencing this code with an underlying cause if identified and documented (e.g., steroid use, trauma).
