Rupture of synovium, right hand

This code signifies a tear or break in the synovial membrane of the right hand. This membrane lines the joint capsule and tendon sheaths, producing synovial fluid that lubricates and nourishes the joint. A rupture can lead to pain, swelling, and impaired hand function.

Apply this code when documentation clearly indicates a traumatic or spontaneous rupture of the synovium specifically affecting the right hand. This diagnosis is typically supported by physical examination findings, imaging studies such as MRI, and a history of injury or pre-existing inflammatory conditions.

• Ensure laterality is explicitly documented as "right hand" to support this specific code.
• Distinguish from other hand injuries like tendon ruptures or ligament tears, which have different codes.
• Consider an external cause code if the rupture is due to an injury, providing additional detail.
