Idiopathic gout, left ankle and foot

This code signifies a diagnosis of idiopathic gout affecting the left ankle and/or foot. Idiopathic gout is a metabolic disorder characterized by recurrent attacks of acute inflammatory arthritis due to elevated uric acid levels, with no identifiable secondary cause. The inflammation in this instance is specifically localized to the left lower extremity joints distal to the knee.

Use this code when documentation confirms a diagnosis of primary gout, meaning the cause is unknown or genetic, and the patient presents with symptoms or signs localized to the left ankle and/or foot. Supporting documentation should include a physician's diagnosis of idiopathic gout and clear identification of the affected anatomical site.

• Ensure documentation specifies "idiopathic" or "primary" gout; otherwise, consider codes for secondary gout.
• Verify the laterality (left) and anatomical site (ankle and/or foot) are clearly documented to avoid miscoding.
• Do not use this code if the gout is due to an underlying condition (e.g., drug-induced, lead poisoning); instead, select a code for secondary gout.
