Idiopathic gout, right wrist

This code signifies a primary form of gout affecting the right wrist, characterized by the deposition of monosodium urate crystals in the joint due to an unknown underlying cause. It results in acute inflammatory arthritis, causing pain, swelling, and tenderness in the affected wrist.

Apply this code when documentation explicitly states a diagnosis of idiopathic gout localized to the right wrist. Supporting clinical notes should detail symptoms consistent with an acute gout flare in this specific joint, without an identified secondary cause such as medication or another underlying disease.

• Ensure laterality is clearly documented as "right wrist"; if unspecified, query the provider.
• Distinguish from secondary gout (e.g., drug-induced) or gout due to renal impairment, which have different codes.
• Do not use for chronic gout or gout with tophi unless the acute idiopathic flare is specifically being treated.
