Infective myositis, unspecified right leg

This code signifies an inflammatory condition of the muscle tissue in the right leg caused by an infection, where the specific pathogen is not identified. It represents a general diagnosis of muscle inflammation due to an infectious agent affecting the right lower extremity.

Apply this code when documentation clearly indicates infective myositis affecting the right leg, but the causative organism (e.g., bacterial, viral, fungal) is not specified. This is appropriate when the physician's notes state "infective myositis, right leg" without further microbiological detail.

• Ensure the documentation explicitly states "infective myositis" and specifies the "right leg."
• Avoid using this code if the specific infectious agent is known; instead, code to a more specific M60.0- subcategory (e.g., M60.013 for Staphylococcus aureus myositis).
• Always review for laterality; this code is specific to the right leg. If the left leg or bilateral involvement is documented, a different code is required.
