Intermittent hydrarthrosis, right hip

This code signifies recurrent, self-limiting effusions within the right hip joint, often presenting with swelling and pain. It describes a condition characterized by episodic synovial fluid accumulation without a clear underlying inflammatory or infectious cause.

Apply this code when documentation explicitly states "intermittent hydrarthrosis" affecting the right hip. Supporting clinical notes should detail recurrent, non-traumatic joint swelling and effusion in the specified anatomical location.

• Ensure documentation specifies "intermittent" and not a persistent or acute effusion.
• Verify the laterality is clearly documented as "right hip" to avoid incorrect coding.
• Do not confuse with other forms of arthropathy or specific inflammatory conditions of the hip; this code is for idiopathic, recurrent effusions.
