Reiter's disease, right elbow

This code signifies an inflammatory arthropathy affecting the right elbow, specifically associated with Reiter's disease (now more commonly referred to as reactive arthritis). It indicates the presence of joint inflammation in this specific anatomical location as a manifestation of the underlying systemic condition.

Apply this code when documentation confirms a diagnosis of reactive arthritis with active inflammation or involvement of the right elbow joint. This typically occurs following an infection elsewhere in the body, such as genitourinary or gastrointestinal infections, and is supported by physician notes detailing the diagnosis and affected joint.

• Ensure documentation clearly specifies "right elbow" involvement; laterality is crucial for accurate coding.
• Code the underlying cause of the reactive arthritis (e.g., Chlamydia, Shigella) if known and documented, following sequencing guidelines.
• Do not confuse with other forms of inflammatory arthritis or unspecified arthropathies; the diagnosis of Reiter's/reactive arthritis must be present.
