Idiopathic chronic gout, left elbow, with tophus (tophi)

This code signifies a chronic, primary form of gout affecting the left elbow, characterized by the presence of tophi. Tophi are deposits of monosodium urate crystals that form visible lumps under the skin or in other tissues, indicating advanced or poorly controlled gout. The idiopathic nature implies the cause is unknown or primary, rather than secondary to another condition.

Use this code when documentation clearly states a diagnosis of idiopathic chronic gout specifically affecting the left elbow, and explicitly mentions the presence of tophi. This code is appropriate for patients presenting with chronic joint pain, swelling, and palpable tophaceous deposits in the left elbow, confirmed by clinical examination or imaging.

• Ensure documentation specifies "idiopathic" or "primary" gout; otherwise, consider codes for secondary gout.
• Verify the laterality (left elbow) and the presence of tophi are explicitly stated in the physician's notes.
• Do not use this code for acute gout flares or gout without tophi; separate codes exist for those presentations.
