The Intracept procedure is a minimally invasive spine treatment that uses heat to destroy a specific nerve inside the vertebral bone, stopping it from sending pain signals. It targets a type of chronic low back pain called vertebrogenic pain, which originates not from a disc or muscle but from damage to the bony endplates of the vertebrae themselves. The procedure received FDA clearance in 2016 and has become an alternative to more invasive options like spinal fusion for appropriately selected patients.
How the Procedure Works
Inside each vertebral body runs a nerve called the basivertebral nerve. This nerve carries pain signals from damaged vertebral endplates, the thin layers of bone and cartilage where the disc meets the vertebra. When those endplates are damaged or inflamed, the basivertebral nerve transmits a chronic, deep ache that conservative treatments often fail to resolve.
The nerve enters through the back of the vertebra and travels forward about 30% to 50% into the bone, where it branches into a cluster of fibers that spread toward the top and bottom endplates. That branching point is the target. A surgeon guides a radiofrequency probe through a small incision into the bone under imaging guidance, then delivers heat (85 degrees Celsius for 15 minutes) to create a small, roughly 1-centimeter spherical lesion that destroys the nerve at its trunk. Once ablated, the nerve can no longer relay pain signals from the damaged endplates to the brain.
Who Is a Candidate
The Intracept procedure is not a general solution for all types of back pain. It is specifically indicated for patients whose pain originates from the vertebral endplates, and confirming that requires a specific finding on MRI called Modic changes. These are signal changes in the bone marrow adjacent to damaged endplates, visible as bright or dark areas on different MRI sequences. Only patients with Type 1 or Type 2 Modic changes qualify, as these patterns correlate with the inflammatory and fatty marrow changes that drive vertebrogenic pain.
Beyond imaging, candidates need to have chronic low back pain lasting at least six months that has not responded to conservative treatments like physical therapy, medications, or injections. The pain is typically axial, meaning it’s centered in the lower back rather than radiating down the legs. Patients who meet these criteria and want to avoid the risks and long recovery of spinal fusion are the primary population for this procedure.
What the Experience Looks Like
The Intracept procedure is performed as an outpatient treatment, meaning you go home the same day. A small incision is made in the back, and the probe is guided into the vertebral body using real-time imaging. The actual ablation takes about 15 minutes per level treated. Dedicated billing codes exist for treating the first two vertebral bodies and for each additional vertebral body, so the procedure can address multiple levels in a single session.
Recovery is notably fast compared to surgical alternatives. Most people can return to work or school within two to three days. If your job involves heavy physical labor, you may need a few extra days. The general guidance is to rest and avoid exercise for about 48 hours after the procedure. There are no major long-term activity restrictions.
How It Compares to Spinal Fusion
Spinal fusion is a major surgery that permanently joins two or more vertebrae together, requires general anesthesia, and involves months of recovery. The Intracept procedure sits on the opposite end of the spectrum. It is percutaneous (done through a small skin puncture), far less invasive, and appeals to patients who cannot or do not want to undergo general anesthesia or a lengthy rehabilitation period.
Prospective studies suggest that 94% of patients who undergo Intracept do not go on to need spine surgery afterward, and patient-reported outcomes have been consistently favorable. That said, the two procedures address somewhat different problems. Fusion is used for structural instability or severe degeneration, while Intracept specifically targets nerve-mediated endplate pain. They are not always interchangeable options, but for patients whose pain is confirmed as vertebrogenic, Intracept offers a much less disruptive path.
Safety and Side Effects
Clinical trials have reported no device-related or procedure-related adverse events through 12 months of follow-up. The primary safety endpoints in these studies focused on musculoskeletal and neurological complications, and neither category showed concerning signals. Patients treated with radiofrequency ablation showed statistically significant improvement in disability scores by three months.
Because the procedure targets a nerve deep inside the bone rather than near the spinal cord or major nerve roots, the risk profile is inherently lower than many other spine interventions. The ablation creates a small, contained lesion at a precise anatomical target, which limits collateral tissue damage.
Insurance Coverage
The procedure has its own dedicated CPT billing codes (64628 for the first two vertebral bodies, 64629 for each additional level), which is an important step for insurance reimbursement. However, coverage varies by insurer and by plan. Some insurers still classify basivertebral nerve ablation as investigational, while others have begun covering it. If you are considering the procedure, verifying coverage with your specific insurance plan beforehand will save you from unexpected costs.
