Transient synovitis, right ankle and foot

This code describes a temporary, non-infectious inflammation of the synovial membrane lining the joint capsule of the right ankle and foot. It typically presents with acute pain and swelling but resolves spontaneously without long-term sequelae.

Use this code for documented cases of transient synovitis affecting the right ankle or foot. Documentation should clearly indicate the transient nature of the inflammation and specify the affected laterality. This diagnosis is often made after ruling out more serious conditions like septic arthritis or fracture.

• Ensure documentation specifies "transient" to differentiate from other forms of synovitis.
• Verify laterality (right ankle/foot) is clearly stated in the medical record.
• Do not use for chronic synovitis or synovitis due to infection or trauma.
