Infective myositis, unspecified foot

This code signifies an inflammatory condition of the muscle tissue in the patient's left foot, caused by an infectious agent. The specific type of infection (e.g., bacterial, viral, fungal) is not documented or is unknown.

Apply this code when documentation clearly indicates infective myositis affecting the left foot, but the causative organism is not specified. This is appropriate for cases where the provider has diagnosed myositis due to infection, but further microbiological identification is pending or was not performed.

• Ensure documentation specifies "left foot" and "infective myositis."
• If the infectious agent is identified, a more specific code from M60.0- should be used.
• Do not use this code if the myositis is non-infectious; consider codes from M60.1- or M60.8-.
