Other osteonecrosis, right toe(s)

This code signifies the death of bone tissue in one or more toes of the right foot due to insufficient blood supply, when the specific type of osteonecrosis is not otherwise classified. This condition can lead to pain, joint collapse, and functional impairment in the affected toe(s).

Apply this code when documentation specifies osteonecrosis of the right toe(s) and the etiology is not avascular necrosis (M87.0-), drug-induced (M87.1-), or other specified forms. Supporting documentation should clearly indicate the affected side (right) and the anatomical location (toe(s)).

• Ensure the documentation specifies "right" toe(s) to differentiate from left (M87.874) or unspecified (M87.879).
• Always look for a more specific osteonecrosis code (e.g., M87.0- for avascular necrosis) before defaulting to "other."
• Code any underlying conditions contributing to the osteonecrosis, such as systemic lupus erythematosus or sickle cell disease, as additional diagnoses.
