Idiopathic gout, left elbow

This code signifies a diagnosis of idiopathic gout affecting the left elbow. Idiopathic gout is a metabolic disorder characterized by recurrent attacks of acute inflammatory arthritis due to the deposition of uric acid crystals in joints, with no identifiable secondary cause. This specific code indicates the manifestation of this condition in the left elbow joint.

Use this code when documentation explicitly states a diagnosis of idiopathic gout localized to the left elbow. This typically occurs in patients presenting with acute pain, swelling, redness, and tenderness in the left elbow, and laboratory findings consistent with hyperuricemia and/or synovial fluid analysis confirming urate crystals. Documentation should clearly specify "idiopathic" and "left elbow."

• Ensure documentation specifies "idiopathic" gout; if a secondary cause is identified, a different code from category M1A (Gout due to other secondary causes) would be appropriate.
• Laterality is crucial; confirm the affected joint is the left elbow.
• Do not confuse with pseudogout (calcium pyrophosphate deposition disease), which has different ICD-10-CM codes.
