Idiopathic gout, left hand

This code signifies a form of arthritis characterized by sudden, severe attacks of pain, redness, and tenderness in the joints, specifically affecting the left hand, without an identifiable secondary cause. It results from the deposition of uric acid crystals in the joints, leading to inflammation.

Use this code when documentation clearly indicates a diagnosis of idiopathic gout affecting the left hand. This diagnosis is typically supported by clinical presentation, elevated serum uric acid levels, and possibly aspiration of synovial fluid showing urate crystals, with no underlying condition contributing to the hyperuricemia.

• Ensure the documentation specifies "idiopathic" or "primary" gout to differentiate from secondary gout.
• Verify the laterality is explicitly stated as "left hand" to avoid using unspecified or bilateral codes.
• Do not confuse with codes for gout due to renal impairment, drug-induced gout, or other specified causes.
