Intermittent hydrarthrosis, left elbow

This code signifies recurrent, transient swelling of the left elbow joint due to an accumulation of synovial fluid, without a clear underlying inflammatory or traumatic cause. It describes a condition characterized by episodes of joint effusion that resolve spontaneously, often with periods of remission.

Apply this code when documentation explicitly states "intermittent hydrarthrosis" affecting the left elbow. Supporting documentation should detail the episodic nature of the swelling and its resolution, and rule out other specific causes of joint effusion.

• Ensure laterality is clearly documented as "left elbow."
• Do not use this code if a specific underlying cause for the hydrarthrosis (e.g., rheumatoid arthritis, infection, trauma) is identified; instead, code the definitive diagnosis.
• Consider sequencing this code after any associated symptoms or signs, if applicable, unless the intermittent hydrarthrosis is the primary reason for the encounter.
