CPT® Code 22614

Add-On Code

Arthrodesis, posterior or posterolateral technique, single interspace; each additional interspace (List separately in addition to code for primary procedure)

Arthrodesis, commonly known as spinal fusion, is a surgical procedure aimed at permanently joining two or more vertebrae in the spine to eliminate motion between them. The posterior or posterolateral technique specifically refers to the approach taken from the back of the body, where an incision is made either in the neck or along the back over the affected vertebral joints. This procedure is typically indicated for patients suffering from conditions such as fractures, instability, or degenerative diseases of the spine. The goal of the surgery is to stabilize the spine, alleviate pain, and restore function. During the procedure, the surgeon prepares the vertebrae for fusion by removing any intervertebral discs and preparing the bone surfaces for grafting. Bone graft material, which can be harvested from the patient's own body or obtained from a donor, is then placed between the vertebrae to promote bone growth and healing. This process may involve the use of internal fixation devices to further stabilize the spine during recovery. The code 22614 is specifically used to report the fusion of each additional interspace beyond the primary procedure, ensuring accurate billing and documentation for the surgical intervention performed.
