Reiter's disease, unspecified elbow

This code represents an inflammatory arthropathy, specifically Reiter's syndrome (now more commonly referred to as reactive arthritis), affecting an unspecified elbow joint. Reiter's disease is characterized by a triad of arthritis, urethritis, and conjunctivitis, often triggered by a preceding infection.

Use this code when documentation clearly indicates a diagnosis of Reiter's disease (reactive arthritis) with involvement of the elbow, but the specific laterality (right or left) is not documented. This code is appropriate when the physician explicitly states "Reiter's disease of the elbow, unspecified."

• Avoid using this code if laterality (right or left elbow) is specified; instead, select the more specific code.
• Ensure documentation supports the diagnosis of Reiter's disease, not just general arthritis.
• Consider sequencing this code after codes for any underlying infectious triggers if known and still active.
