Infective myositis, left shoulder

This code signifies inflammation of the skeletal muscle in the left shoulder region caused by an infectious agent. This condition typically presents with pain, swelling, and tenderness in the affected shoulder, often accompanied by systemic signs of infection.

Apply this code when documentation clearly indicates an infection of the muscle tissue specifically located in the patient's left shoulder. This diagnosis is supported by findings such as positive cultures from muscle biopsy, imaging studies showing muscle inflammation, and clinical signs of infection localized to the left shoulder.

• Ensure the documentation specifies "infective" myositis and not other forms of myositis (e.g., inflammatory, toxic).
• Verify the laterality is explicitly stated as "left shoulder"; if unspecified, an unspecified laterality code would be more appropriate.
• Code any underlying infectious agent (e.g., bacteria, virus) as an additional diagnosis, if identified.
