Reiter's disease, unspecified wrist

This code describes an inflammatory arthritis, also known as reactive arthritis, affecting an unspecified wrist, where the specific cause or manifestation of Reiter's disease is not further detailed. Reactive arthritis is typically triggered by an infection elsewhere in the body, leading to joint inflammation, often accompanied by urethritis and conjunctivitis.

Use this code when documentation confirms a diagnosis of Reiter's disease (reactive arthritis) affecting the wrist, but the laterality (right or left) is not specified. This code is appropriate when the physician explicitly states "Reiter's disease, wrist" without further anatomical detail.

• Avoid using this code if the laterality of the affected wrist (right or left) is documented; instead, choose a more specific code.
• Ensure the documentation clearly links the wrist involvement to Reiter's disease.
• Consider sequencing this code after the code for the underlying infection, if known and still active.
