Idiopathic chronic gout, left elbow, without tophus (tophi)

This code identifies a chronic inflammatory arthritis affecting the left elbow, caused by the deposition of uric acid crystals, but without the presence of visible or palpable tophi. The condition is idiopathic, meaning the underlying cause is unknown. It signifies a persistent form of gout in a specific anatomical location.

Apply this code when documentation clearly indicates a diagnosis of chronic gout affecting the left elbow, and explicitly states the absence of tophi. This is appropriate for patients experiencing recurrent or persistent gout flares in this joint. Supporting documentation includes physician notes detailing the chronicity, joint involvement, and lack of tophaceous deposits.

• Ensure documentation specifies "chronic" and "idiopathic" gout; acute gout would use a different subcategory.
• Verify the affected joint is the left elbow and that tophi are explicitly noted as absent.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when managing comorbidities.
