Infective myositis, right forearm

This code signifies an inflammation of the muscles in the right forearm caused by an infection. This condition typically presents with pain, swelling, and tenderness in the affected area, often accompanied by systemic signs of infection like fever.

Apply this code when documentation explicitly states infective myositis affecting the right forearm. Supporting documentation should include a confirmed diagnosis of myositis and specify an infectious etiology, along with the precise anatomical location.

• Ensure the documentation clearly identifies the right forearm as the affected site.
• Distinguish from non-infectious myositis (e.g., autoimmune) or myalgia without inflammation.
• Code any underlying infectious organism (e.g., bacterial, viral) as an additional diagnosis.
