Infective myositis, right thigh

This code signifies inflammation of the muscles in the right thigh caused by an infectious agent. This condition typically presents with localized pain, swelling, and tenderness, often accompanied by systemic signs of infection such as fever.

Apply this code when documentation clearly indicates myositis of the right thigh due to an infection, such as bacterial, viral, or parasitic. Supporting documentation should include physician notes detailing the diagnosis, location, and infectious etiology.

• Ensure the documentation specifies "infective" myositis to differentiate from other forms of myositis.
• Always verify the laterality (right) and anatomical site (thigh) are explicitly stated.
• Code the underlying infectious organism first, if known and documented, followed by this code.
