Intermittent hydrarthrosis, right shoulder

This code signifies a recurrent, non-inflammatory effusion within the right shoulder joint, characterized by episodes of swelling and fluid accumulation that resolve spontaneously. It indicates a condition where the joint intermittently fills with synovial fluid without evidence of infection or systemic inflammatory disease.

Apply this code when documentation clearly states "intermittent hydrarthrosis" affecting the right shoulder. This diagnosis is typically supported by clinical examination noting recurrent joint swelling, aspiration revealing non-inflammatory fluid, and exclusion of other causes like infection or trauma.

• Ensure documentation specifies "intermittent" and not chronic or persistent hydrarthrosis.
• Verify laterality; this code is specific to the right shoulder.
• Code any underlying cause or associated conditions if documented, following sequencing guidelines.
