Drug-induced chronic gout, right hip, without tophus (tophi)

This code signifies chronic inflammatory arthritis affecting the right hip joint, specifically caused by a medication, without the presence of urate crystal deposits (tophi). The condition is characterized by persistent pain, swelling, and stiffness in the hip due to drug-induced hyperuricemia.

Apply this code when documentation clearly indicates chronic gout in the right hip, directly attributed to a prescribed or illicit drug, and explicitly states the absence of tophi. This diagnosis is typically supported by a history of medication use, elevated serum uric acid levels, and imaging studies confirming hip involvement without visible tophaceous deposits.

• Ensure the documentation specifies "chronic" gout and explicitly links it to a drug.
• Verify the affected joint is the "right hip" and that "without tophus (tophi)" is clearly stated.
• Do not use this code if the gout is acute, idiopathic, or involves other joints, or if tophi are present.
