Other reactive arthropathies, right shoulder

This diagnosis code signifies an inflammatory joint condition affecting the right shoulder, triggered by an infection elsewhere in the body, but not directly caused by the infection itself within the joint. It represents a sterile synovitis, meaning no infectious organisms are present in the joint fluid.

Apply this code when documentation indicates a reactive arthritis specifically impacting the right shoulder, often following a gastrointestinal or genitourinary infection. Supporting documentation should clearly state "reactive arthropathy" and specify the right shoulder as the affected site, with no evidence of direct joint infection.

• Ensure the documentation specifies "right shoulder" to differentiate from other shoulder or bilateral involvement.
• Do not use this code if the arthritis is due to direct infection of the joint; instead, use a code from the M00 category.
• Code the underlying infection first, if known and still active, followed by this code for the reactive arthropathy.
