Infective myositis, right ankle

This code signifies an inflammatory condition of the muscles in the right ankle, specifically caused by an infection. This infection leads to muscle pain, weakness, and swelling in the affected area.

Use this code when documentation clearly indicates an infectious etiology for myositis localized to the right ankle. Supporting documentation should include physician notes detailing the infection, symptoms, and the specific anatomical site.

• Ensure the documentation specifies "infective" myositis, not just general myositis.
• Verify the laterality is explicitly stated as "right ankle."
• Consider coding an underlying infectious agent if identified and documented.
