Drug-induced gout, right wrist

This code signifies an acute inflammatory arthritis of the right wrist caused by an adverse reaction to a medication. It involves the deposition of uric acid crystals in the joint, leading to sudden and severe pain, swelling, redness, and tenderness.

Apply this code when documentation clearly indicates gout in the right wrist that is directly attributable to a prescribed or illicit drug. This typically involves a patient presenting with classic gout symptoms following the initiation or change of a medication known to affect uric acid levels.

• Ensure documentation specifies "drug-induced" and identifies the right wrist as the affected joint.
• Always code the adverse effect of the drug (T36-T50 with a 5th or 6th character of 5) as a secondary diagnosis to identify the causative agent.
• Distinguish from primary gout (M10.0-) or gout due to renal impairment (M10.3-), which are not drug-induced.
