Infective myositis, unspecified ankle

This code signifies an inflammatory condition of the muscles in the left ankle region caused by an infectious agent. It indicates the specific pathogen responsible for the myositis has not been identified or documented. The infection leads to muscle pain, swelling, and impaired function of the affected ankle.

Use this code when documentation specifies infective myositis affecting the left ankle, but the causative organism (e.g., bacterial, viral, fungal) is not determined or recorded. This code is appropriate when the physician's diagnosis explicitly states "infective myositis, left ankle, unspecified."

• Ensure laterality is clearly documented as "left ankle" to support this specific code.
• If the infectious agent is identified, a more specific code from the M60.0- category should be used (e.g., M60.074 for Staphylococcus aureus infective myositis, left ankle).
• Always sequence this code after any underlying systemic infection if applicable and documented.
