Infective myositis, unspecified shoulder

This code signifies inflammation of the muscle tissue in an unspecified shoulder, caused by an infectious agent. It represents a general diagnosis of infective myositis when the specific shoulder (left or right) is not documented.

Use this code when documentation indicates infective myositis affecting the shoulder, but the laterality (left or right) is not specified. This typically occurs when a definitive diagnosis of muscle infection is made, but the exact anatomical side is missing from the physician's notes.

• Avoid using this code if the laterality of the affected shoulder is clearly documented; instead, select a more specific code (M60.011 or M60.012).
• Ensure the documentation explicitly states an infectious etiology for the myositis, as opposed to other forms of myositis (e.g., inflammatory, toxic).
• Query the provider for laterality if possible to achieve a more specific code and improve data accuracy.
