Overview of CPT Code 22820: Posterior spinal fusion, posterior approach

CPT Code 22820 refers to a surgical procedure known as posterior spinal fusion, which is performed through the back to stabilize the spine. This procedure is typically indicated for patients with spinal instability or deformities.

When CPT Code 22820 is Used?

This procedure is appropriate in various clinical scenarios.

• Severe spinal instability due to trauma or degenerative disease.
• Scoliosis or other spinal deformities requiring correction.
• Failed conservative treatment for back pain or spinal deformity.
• Tumors affecting spinal stability.

Symptoms Indicating This Procedure

Patients may report several symptoms that lead to the consideration of this procedure.

• Chronic back pain that does not improve with conservative treatment.
• Numbness or weakness in the legs.
• Visible spinal deformity.
• Difficulty walking or maintaining balance.

Causes and Risk Factors

Several factors can contribute to the need for posterior spinal fusion.

• Degenerative disc disease.
• Spinal fractures from trauma.
• Congenital spinal deformities.
• Previous spinal surgeries leading to instability.

Diagnostic Tests Before Procedure

Several diagnostic tests are typically performed to assess the need for this procedure.

• X-rays to evaluate spinal alignment and stability.
• MRI to assess soft tissue and nerve involvement.
• CT scans for detailed imaging of the spine.
• Electromyography (EMG) to evaluate nerve function.

Procedure Description

The procedure involves several key steps.

• Patient is placed under general anesthesia.
• An incision is made along the back to access the spine.
• Damaged or unstable vertebrae are identified.
• Bone graft material is placed to promote fusion.
• Metal rods and screws may be used to stabilize the spine.
• The incision is closed with sutures or staples.

Patients should follow specific guidelines before the surgery.

• Avoid eating or drinking after midnight before the surgery.
• Discuss all medications with the surgeon, including over-the-counter drugs.
• Arrange for transportation to and from the hospital.
• Follow any pre-operative instructions provided by the healthcare team.

Recovery and Aftercare

Recovery from this procedure typically involves several steps.

• Hospital stay of 1 to 3 days post-surgery.
• Gradual return to normal activities over several weeks.
• Physical therapy to aid recovery and improve strength.
• Pain management with prescribed medications.

Possible Complications

As with any surgery, there are potential risks involved.
