CPT® Code 29705

Bivalving a cast is a procedure that involves creating openings on both sides of a full arm or full leg cast. This technique is primarily employed to alleviate excessive pressure that may build up within the cast due to swelling or distension of the underlying body part. The procedure is performed using an oscillating saw, which is specifically designed to cut through the cast material and padding without causing harm to the skin or underlying tissues. The cuts are strategically made to ensure that the cast continues to provide adequate support to the injured area while allowing for necessary adjustments as swelling decreases. After the bivalving process, an elastic wrap is applied over the cast to maintain stability and can be adjusted as the patient's condition improves. In cases where the cast needs to be completely removed, the oscillating saw is again utilized to cut the cast on both sides, followed by the careful use of scissors to cut through the underlying padding and stockinette. Once the cast is removed, the skin is thoroughly inspected for any signs of breakdown or irritation, ensuring the patient's safety and comfort. It is important to note that specific codes are designated for different types of casts, such as 29700 for bivalving or removal of a gauntlet, boot, or body cast, 29705 for a full arm or leg cast, and 29710 for a shoulder or hip spica, Minerva cast, or Risser jacket.
