Other reactive arthropathies, vertebrae

This code signifies an inflammatory joint condition affecting the vertebral column that arises as a reaction to an infection elsewhere in the body. It is characterized by sterile inflammation of the spinal joints, distinct from direct infectious arthritis. The underlying infection is typically extra-articular and often gastrointestinal or genitourinary.

Apply this code when documentation specifies reactive arthritis primarily affecting the vertebrae, and the causative infection is not directly within the spine. This diagnosis is supported by clinical findings of spinal inflammation, a history of a preceding infection, and negative cultures from the affected joints.

• Ensure documentation clearly distinguishes reactive arthropathy from infectious spondylitis or other forms of inflammatory spondyloarthropathy.
• Always code the underlying infection first, if known and still active, followed by this code for the reactive arthropathy.
• Avoid using this code if the vertebral involvement is due to a direct infection or another specified inflammatory spondyloarthropathy (e.g., ankylosing spondylitis).
