Infective myositis, other site

This code signifies inflammation of muscle tissue caused by an infectious agent, affecting any anatomical site other than those specified by more precise codes (e.g., trunk, upper limb, lower limb). It indicates a direct infection of the muscle, leading to pain, swelling, and impaired function.

Use this code when documentation specifies infective myositis in a location not covered by a more specific M60.0- subcategory, such as the head, neck, or multiple unspecified sites. Supporting documentation should clearly state the diagnosis of infective myositis and the affected "other" or unspecified body region.

• Always strive for a more specific anatomical site code (M60.00-M60.07) if documented.
• Do not use this code for myositis due to non-infectious causes; refer to M60.1- for interstitial myositis or M60.8- for other myositis.
• Code the underlying infectious agent (e.g., B95-B97) as an additional diagnosis, if known and documented.
