Postdysenteric arthropathy, right wrist

This code describes an inflammatory joint condition affecting the right wrist that develops as a reactive arthritis following a dysenteric infection. It is a sterile arthritis, meaning the joint itself is not infected, but rather the immune system's response to a prior gastrointestinal infection leads to joint inflammation.

Use this code when documentation clearly indicates a diagnosis of reactive arthritis of the right wrist, specifically linked to a preceding dysenteric illness. The provider's notes should explicitly state the post-dysenteric etiology and the affected joint.

• Ensure the documentation specifies "right wrist" as the affected joint; laterality is crucial.
• Confirm the causal link to a dysenteric infection is explicitly stated by the provider.
• Do not confuse with other forms of reactive arthritis or infectious arthritis.
