Intermittent hydrarthrosis, left wrist

This code signifies recurrent, temporary swelling of the left wrist joint due to an accumulation of synovial fluid, without an identifiable underlying cause like infection or trauma. The condition is characterized by episodes of joint effusion that resolve spontaneously, often with symptom-free intervals.

Apply this code when documentation explicitly states "intermittent hydrarthrosis" affecting the left wrist. Supporting clinical notes should describe episodic joint swelling and effusion, and rule out other etiologies such as inflammatory arthritis, crystal arthropathy, or injury.

• Ensure laterality is clearly documented as "left wrist"; if unspecified, a different code for unspecified side would be appropriate.
• Distinguish from chronic hydrarthrosis or hydrarthrosis due to a specific underlying condition, which would require a more specific code.
• Always review for any associated systemic conditions or inflammatory markers that might indicate a different primary diagnosis.
