Infective myositis, left finger(s)

This diagnosis code signifies an inflammatory condition of the skeletal muscle in the left finger(s) caused by an infectious agent. This can result from bacterial, viral, fungal, or parasitic infections directly affecting the muscle tissue.

Apply this code when documentation specifies an infection of the muscle tissue within one or more fingers of the patient's left hand. The physician's notes should clearly indicate the infectious etiology of the myositis and laterality.

• Ensure the documentation explicitly states "infective" myositis and specifies the left finger(s).
• Do not use for non-infectious myositis; consider codes from M60.8- or M60.9- for other specified or unspecified myositis.
• Code the underlying infectious organism first, if known and documented (e.g., B95-B97 for bacterial agents).
