Drug-induced chronic gout, right elbow, with tophus (tophi)

This code signifies a chronic inflammatory arthritis of the right elbow caused by a medication, characterized by the presence of urate crystal deposits (tophi). The drug-induced nature differentiates it from primary gout, and the chronicity indicates a persistent or recurrent condition.

Apply this code when documentation clearly states chronic gout of the right elbow, explicitly linked to a drug, and confirms the presence of tophaceous deposits. Supporting documentation would include physician notes detailing the drug etiology, joint examination findings, and imaging or lab results confirming tophi.

• Ensure the documentation specifies "drug-induced" and "chronic" to differentiate from acute or primary gout.
• Verify the laterality (right elbow) and the presence of tophi are explicitly stated.
• Do not use this code for gout without documented tophi or if the gout is not confirmed as drug-induced.
