How To Use CPT Code 29040

CPT 29040 describes the application of a Minerva-type body cast, which includes the head, to stabilize the cervical spine and treat conditions such as torticollis, cervical or thoracic spine injuries, and scoliosis. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 29040?

CPT 29040 is used to describe the application of a Minerva-type body cast, which is a cast that covers the trunk and spine, including the neck, jaw, and head. This type of cast is used to stabilize the cervical spine and treat conditions such as torticollis, cervical or thoracic spine injuries, and scoliosis. The cast is applied by a healthcare provider and is made of casting material, such as plaster of Paris or fiberglass, that is layered over padding to protect the skin.

2. Official Description

The official description of CPT code 29040 is: ‘Application of body cast, shoulder to hips; including head, Minerva type.’

3. Procedure

1. The healthcare provider begins by conducting a complete neurovascular exam of the affected region.
2. If necessary, cervical traction may be applied while the cast is being applied.
3. The provider covers the trunk, including the ribs, down to the top of the hips and up over the head and neck with casting material.
4. Spaces are left or cut from the casting material to expose the face, ears, and top of the head.
5. A layer of stockinette, a loose knit fabric, is applied, followed by cotton synthetic padding to protect the skin.
6. Wet casting material, such as plaster of Paris or fiberglass, is applied in strips over the padding to build up the cast.
7. The underlying stockinette is rolled over the openings in the cast to smooth out the edges.
8. The cast is allowed to dry, and the fit is reassessed. If necessary, the openings for the face, ears, and top of the head are enlarged.

4. Qualifying circumstances

CPT 29040 is used for patients who require the application of a Minerva-type body cast to stabilize the cervical spine. This may include patients with conditions such as torticollis, cervical or thoracic spine injuries, and scoliosis. The cast is applied by a healthcare provider and is made of casting material, such as plaster of Paris or fiberglass.

5. When to use CPT code 29040
