Overview of CPT Code 22630:Posterior Lumbar Interbody Fusion

CPT Code 22630 refers to the surgical procedure known as Posterior Lumbar Interbody Fusion, which is performed to stabilize the lumbar spine by fusing two or more vertebrae together using bone grafts and instrumentation.

When CPT Code 22630 is Used?

This procedure is indicated in various clinical scenarios.

• Severe degenerative disc disease causing significant pain and disability.
• Spondylolisthesis resulting in spinal instability.
• Recurrent herniated discs that have not responded to conservative treatments.

• Obesity increasing stress on the spine.
• Occupational hazards involving heavy lifting or repetitive motion.

Diagnostic Tests Before Procedure

A variety of diagnostic tests are utilized to assess the need for surgery.

• X-rays to evaluate spinal alignment and degeneration.
• MRI scans to visualize soft tissue structures and nerve compression.
• CT scans for detailed imaging of the bony anatomy.
• Electromyography (EMG) to assess nerve function.
• Discography to evaluate disc pain.

Procedure Description

The surgical procedure involves several key steps.

• Patient is placed under general anesthesia.
• An incision is made in the lower back to access the spine.
• The affected disc(s) are removed to relieve pressure on nerves.
• Bone graft material is placed in the intervertebral space.
• Instrumentation such as screws and rods are used to stabilize the spine.
• The incision is closed with sutures or staples.

Preparation for the Procedure

Patients should follow specific guidelines to prepare for surgery.

• Consult with the surgeon about medications to avoid prior to surgery.
• Arrange for transportation to and from the surgical facility.
• Follow pre-operative fasting instructions.
• Discuss any allergies or medical conditions with the healthcare team.
• Complete any required pre-operative testing.

Recovery and Aftercare

Post-operative recovery involves several important aspects.

• Hospital stay of 1-3 days for monitoring.
• Gradual return to normal activities over several weeks.
• Physical therapy to aid in recovery and strengthen the back.
• Pain management with prescribed medications.
• Wound care instructions to prevent infection.

Possible Complications

As with any surgical procedure, there are potential risks involved.

• Infection at the surgical site.
• Nerve damage leading to persistent pain or weakness.
• Blood clots in the legs or lungs.
