Rupture of synovium, left wrist

This code signifies a tear or break in the synovial membrane surrounding a joint in the left wrist. This rupture allows synovial fluid to escape, potentially causing pain, swelling, and impaired joint function. It is an acute injury, often resulting from trauma or sudden forceful movements.

Apply this code when documentation clearly indicates a rupture of the synovium specifically affecting the left wrist. This diagnosis is typically supported by physical examination findings, patient history of acute injury, and imaging studies such as MRI that visualize the synovial tear.

• Differentiate from other wrist injuries like sprains (S63.-) or tenosynovitis (M65.84-).
• Ensure laterality (left wrist) is explicitly documented; otherwise, an unspecified code may be necessary.
• Look for documentation of the cause of rupture, as an external cause code may also be warranted.
