1. What is CPT Code 21421?

CPT 21421 is used to describe the closed treatment of a palatal or maxillary fracture, specifically a LeFort I type fracture.

The procedure involves manipulation and splinting to realign and stabilize the fractured bones.

2. Official Description

The official description of CPT code 21421 is: ‘Closed treatment of palatal or maxillary fracture (LeFort I type), with interdental wire fixation or fixation of denture or splint.’

3. Procedure

When performing CPT 21421, the healthcare provider begins by ensuring the patient is appropriately prepped and anesthetized. They then examine the patient and check the airway to ensure proper ventilation. The provider uses manipulation techniques to place the fractured bones in the correct position. To stabilize the bones, interdental wires, dentures, or splints are attached to the teeth. This helps hold the fractured bones in place and provides stability during the healing process.

It is important to note that codes specifying a LeFort I type fracture are not exclusively reserved for textbook LeFort I fractures. The provider should choose the code that most closely resembles the type of repair performed.
