Drug-induced chronic gout, right wrist, without tophus

This code signifies a chronic inflammatory arthritis of the right wrist caused by medication, specifically characterized by the deposition of uric acid crystals without the presence of visible or palpable tophi. The condition results in persistent pain, swelling, and stiffness in the affected joint due to the drug's influence on uric acid metabolism.

Use this code when documentation clearly indicates chronic gout in the right wrist that is directly attributed to a prescribed or illicit drug, and the physician explicitly states the absence of tophi. This applies to patients experiencing ongoing symptoms of gout secondary to medication, rather than primary gout or acute episodes.

• Ensure documentation specifies "drug-induced" and "chronic" gout, along with the affected joint (right wrist) and the absence of tophi.
• Do not use this code for acute drug-induced gout; refer to the M10.2x series for acute presentations.
• Consider an additional code to identify the specific drug causing the adverse effect, if known and documented.
