Infective myositis, unspecified site

This code signifies inflammation of muscle tissue caused by an infection, without specifying the particular muscle group affected. It represents a general diagnosis of muscle infection where the causative agent and specific location are not documented.

Use this code when documentation clearly indicates myositis due to an infectious process, but the physician has not specified the anatomical site of the infection. This code is appropriate when the medical record lacks detail regarding the affected muscle(s).

• Avoid using this code if a more specific site of infective myositis is documented (e.g., M60.01- for shoulder, M60.02- for upper arm).
• Always attempt to query the provider for a more specific anatomical site if possible, as this code represents an unspecified diagnosis.
• Code an additional diagnosis to identify the infectious agent, if known and documented.
