Other reactive arthropathies, left hip

This code signifies an inflammatory joint condition affecting the left hip that develops in response to an infection elsewhere in the body, but is not directly caused by the infection itself within the joint. It encompasses various forms of reactive arthritis not specifically classified elsewhere, presenting with symptoms like pain, swelling, and stiffness in the left hip.

Apply this code when documentation clearly indicates reactive arthropathy localized to the left hip, without evidence of direct joint infection. This diagnosis is typically made after ruling out other causes of hip pain and identifying a preceding infection (e.g., gastrointestinal, genitourinary). Supporting documentation should include physician notes detailing the reactive nature of the arthritis and its specific manifestation in the left hip.

• Ensure documentation specifies "left hip" to avoid laterality errors.
• Do not use this code if the hip joint itself is infected; instead, consider codes for infectious arthritis.
• Always code the underlying infection, if known, as a primary diagnosis when applicable, followed by this code for the reactive arthropathy.
