Overview of CPT Code 22605: Spinal Fusion, Posterior Interbody, Lumbar

CPT Code 22605 refers to a surgical procedure known as spinal fusion, specifically performed through a posterior interbody approach in the lumbar region of the spine. This procedure aims to stabilize the spine by fusing two or more vertebrae together, often to alleviate pain and restore function.

When CPT Code 22605 is Used?

This procedure is indicated in various clinical scenarios.

• Severe degenerative disc disease causing significant pain and disability.
• Spondylolisthesis where one vertebra slips over another.
• Spinal instability following trauma or surgery.
• Recurrent herniated discs that do not respond to conservative treatments.

Symptoms Indicating This Procedure

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

• Chronic lower back pain that does not improve with conservative treatments.
• Radiating pain into the legs (sciatica).
• Numbness or weakness in the legs.
• Difficulty walking or standing for prolonged periods.

Causes and Risk Factors

Several factors can contribute to the need for spinal fusion.

• Age-related degeneration of spinal discs.
• Injury or trauma to the spine.
• Genetic predisposition to spinal disorders.
• Obesity, which can increase stress on the spine.

Diagnostic Tests Before Procedure

Several diagnostic tests are typically performed to assess the condition of the spine.

• MRI to visualize soft tissues and discs.
• CT scans for detailed images of the spine.
• X-rays to assess alignment and structural integrity.
• Electromyography (EMG) to evaluate nerve function.

Procedure Description

The spinal fusion procedure involves several key steps.

• The patient is placed under general anesthesia.
• An incision is made in the lower back to access the spine.
• The affected disc is removed to prepare for fusion.
• Bone graft material is placed between the vertebrae to promote fusion.
• Instrumentation such as screws and rods may be used for stabilization.
• The incision is closed with sutures or staples.

Preparation for the Procedure

Patients should follow specific guidelines to prepare for 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

Post-operative recovery is crucial for successful outcomes.

• Hospital stay may last 1-3 days depending on recovery.
• Pain management with prescribed medications.
• Physical therapy may begin shortly after surgery.
• Avoid heavy lifting and twisting for several weeks.

Possible Complications

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

• Infection at the surgical site.
• Nerve damage leading to weakness or numbness.
• Non-union of the vertebrae, requiring further surgery.
• Blood clots in the legs or lungs.

Post-Procedure Follow-Up

Regular follow-up is essential to monitor recovery.

• Initial follow-up appointment within 2 weeks post-surgery.
• Subsequent visits at 6 weeks, 3 months, and 6 months.
• Imaging studies may be repeated to assess fusion progress.

Alternative Treatments

There are non-surgical options available for managing spinal issues.

• Physical therapy to strengthen back muscles.
• Chiropractic care for spinal alignment.
• Pain management techniques including injections.
• Medications such as NSAIDs for pain relief.

Home Care Tips

Patients can take steps at home to aid recovery.

• Follow prescribed medication schedules for pain management.
• Engage in light activities as tolerated, avoiding strain.
• Use ice or heat packs to manage discomfort.
• Maintain a healthy diet to support healing.

Patient Education & Prevention

Understanding the condition can help prevent recurrence.

• Maintain a healthy weight to reduce spinal stress.
• Practice good posture to support spinal health.
• Engage in regular exercise to strengthen back muscles.
• Avoid high-impact activities that may strain the spine.
