In simple words: The doctor removes or adjusts a cast on your entire arm or leg that was put on by a different doctor. This is done if the cast isn't needed anymore, needs to be changed, or is too tight because of swelling.

This code describes the removal or bivalving of an existing cast applied by another healthcare provider on a full arm or full leg. This procedure is performed when the cast is no longer required, needs replacement, or has become too tight due to swelling.The procedure involves using a cast saw to cut through the cast, a cast spreader to separate the cut sections, and blunt scissors to remove the padding. If the bone is healed, the cast is removed. If not, and bivalving was done to relieve pressure, the cast halves are secured with a bandage.

Example 1: A patient presents with a full leg cast that was placed by another physician. The cast has become too tight due to swelling. The physician performs a bivalving procedure (29705) to relieve the pressure., A patient with a full arm cast, originally applied by a different provider, has completed the healing process. The physician removes the cast (29705)., A patient has a full leg cast applied by another physician. Due to an infection developing under the cast, the cast needs to be removed and a new one put on. The current cast is removed (29705) and a new one applied using the appropriate application code.

Documentation should include the original date and reason for cast application, the reason for removal/bivalving, the condition of the limb, any complications, and any further treatment plan.

** Do not report this code if your practice applied the cast initially, as cast application and removal are typically included in the initial application code. This code does not include the application of a new or replacement cast.
