Infective myositis, left foot

This code describes an inflammatory condition of the left foot muscles caused by an infection. It signifies the presence of an infectious agent directly affecting the muscle tissue, leading to pain, swelling, and impaired function in the specified anatomical location.

Assign this code when documentation clearly states infective myositis affecting the left foot. This typically occurs following a penetrating injury, surgery, or hematogenous spread of an infection. Supporting documentation should include physician notes detailing the diagnosis, location, and evidence of infection (e.g., positive cultures, imaging findings).

• Ensure laterality is explicitly documented as "left foot" to support this specific code.
• Distinguish from non-infectious myositis (e.g., M60.874) or other inflammatory conditions of the foot.
• Code the underlying infectious agent (e.g., B95-B97) as an additional diagnosis, if known.
