If you have chronic low back pain that gets worse with sitting, gets worse with bending forward, and your MRI shows what your radiologist called “Modic changes” or “endplate changes” — there is a procedure most spine surgeons and pain doctors still do not offer. It is called basivertebral nerve ablation, sold under the brand name Intracept. It is a single-session, outpatient, FDA-approved procedure that targets one specific cause of chronic low back pain: an irritated nerve inside your vertebral bone. I perform Intracept regularly in my Hoffman Estates practice, and this is the patient guide I wish every chronic low back pain patient had before they walked into my office.

What is basivertebral nerve ablation
Basivertebral nerve ablation, or BVA (also called Intracept after the brand name from Relievant Medsystems), is a single-session radiofrequency ablation of one specific nerve inside the vertebral body. The basivertebral nerve runs through a small canal in the vertebral bone and carries pain signals from the inflamed bone marrow and endplate up to the spinal cord and brain. By ablating that nerve, we silence the pain signal at its source.
Intracept is FDA-approved for the treatment of chronic vertebrogenic low back pain. It is a one-time procedure, performed under conscious sedation, taking roughly 60 to 90 minutes. There is no implant, no hardware, no fusion, and no general anesthesia.
Vertebrogenic pain: the diagnosis you may not have heard of
If you have chronic low back pain, you have probably been told you have “degenerative disc disease,” “facet arthritis,” or “spinal stenosis.” Those are real conditions, but for a meaningful subset of patients, the actual pain generator is something different: vertebrogenic pain from inflammation of the vertebral endplate.
The vertebral endplate is the thin layer of bone where each vertebra meets the disc. When that interface becomes chronically inflamed, your radiologist sees specific signal changes on MRI called Modic Type 1 (active inflammation, bright on T2, dark on T1) or Modic Type 2 (fatty replacement, bright on both). Those changes correlate with vertebrogenic pain.
Estimates suggest 20 to 40 percent of chronic low back pain patients have vertebrogenic pain as a meaningful component. Most are misdiagnosed for years because the diagnosis requires both: clinical pattern (axial low back pain, worse with sitting and forward bending, no radiation to legs) AND MRI evidence (Modic changes at the same level).
How Intracept actually works
I make a small access port into the back of the affected vertebra under fluoroscopic guidance, navigate a curved cannula through the bone to the basivertebral nerve, and apply radiofrequency energy at 85 degrees Celsius for 15 minutes per level. The heat coagulates the nerve at the source. The procedure typically treats 1 to 2 levels (most commonly L4 and L5). The bone surrounding the nerve recovers quickly because the access port is the size of a pencil eraser.
The whole procedure runs about 60 to 90 minutes. You are awake or lightly sedated. You go home the same day, walking out under your own power.
Who is a candidate for Intracept
The right candidate has all four of these:
- Chronic low back pain for at least 6 months that has not responded adequately to conservative care.
- Pain pattern consistent with vertebrogenic pain: axial low back pain (mostly midline), worse with sitting and forward bending, NOT radiating below the knee.
- MRI evidence of Modic Type 1 or Type 2 endplate changes at one or two adjacent vertebral levels.
- Failed conservative care: physical therapy, NSAIDs, and ideally at least one epidural steroid injection that gave only short-term relief.
Importantly, Intracept does NOT work for radicular pain (sciatica), facet joint arthritis as the primary pain generator, or stenosis-driven leg symptoms. It is targeted to one specific anatomic problem.
Who is NOT a candidate
- Primarily radicular leg pain (sciatica)
- No Modic changes on MRI
- Spondylolisthesis or major instability at the target level
- Active spinal infection or tumor
- Severe osteoporosis at the target level (relative)
- Pregnancy
What the SMART and INTRACEPT trials actually show
The evidence base for Intracept is unusually strong for a newer interventional procedure. The pivotal trials:
SMART trial (Khalil et al., 2019): a sham-controlled randomized trial of 140 patients with chronic vertebrogenic low back pain. The Intracept arm had significantly greater pain reduction (Oswestry Disability Index improvement) at 3 months compared to sham. Crossover analysis at 12 months showed sustained benefit.
INTRACEPT trial (Fischgrund et al., 2018, with 5-year follow-up published 2024): 225 patients followed for 5 years. At 5 years, mean pain reduction was sustained at 4.4 points on a 10-point VAS scale. 76 percent of patients still had a clinically meaningful response. Few procedures in interventional pain medicine have this kind of durable 5-year data.
Realistic expectations: 65 to 75 percent of well-selected patients get at least 50 percent pain reduction at 12 months. Of those responders, roughly 75 to 80 percent maintain benefit at 5 years.
Medicare and insurance coverage in Illinois
Coverage has expanded substantially. Medicare covers Intracept under most LCDs (Local Coverage Determinations) for qualifying patients. Commercial insurers in Illinois (Blue Cross Blue Shield, Aetna, UnitedHealthcare, Humana, Cigna) increasingly cover it, with prior authorization, when the documentation is clean.
Standard documentation packet:
- Recent lumbar MRI showing Modic Type 1 or 2 changes at the target levels
- Documentation of at least 6 months of chronic low back pain
- Documentation of failed conservative care (PT, NSAIDs)
- Documentation of at least one prior epidural steroid injection (most insurers)
- Functional status documentation (ODI, VAS pain scores)
My team handles all the prior authorization. Typical timeline from green-light to scheduled: 3 to 5 weeks for commercial insurance; faster for Medicare.
What the day-of looks like
Pre-procedure (1 week prior). Office visit to review your MRI and confirm Modic changes and target levels. We discuss whether to stop blood thinners (most patients pause anticoagulation 5 to 7 days before).
Day of procedure. Arrive about an hour before. Vitals, IV started, brief conversation. You go to the procedure room, lie face down on a fluoroscopy table, get local anesthetic at the entry site, and conscious sedation. The procedure runs 60 to 90 minutes.
Post-procedure. Recovery in our suite for 30 to 60 minutes. You walk out under your own power. No driving the day of the procedure.
Recovery timeline
- Day of procedure: Light walking around the house. Avoid lifting over 10 lbs. No driving.
- Days 1 to 3: Some local soreness at the entry site, like a deep bruise. Tylenol or NSAIDs (if not on blood thinners).
- Days 4 to 14: Most patients return to desk work and most light activities. Many notice gradual pain reduction starting in the first 2 weeks.
- Weeks 4 to 8: Maximum benefit usually emerges in this window. Some patients keep improving up to 12 weeks.
- Beyond 3 months: Full activity. Manual labor and heavy lifting cleared. Most patients also engage in core strengthening physical therapy starting 4 to 6 weeks after.
Combining Intracept with other treatments
Modern interventional pain medicine treats chronic low back pain as multi-mechanism. For the right patient, I will combine Intracept with:
- Epidural steroid injections for any coincident inflammatory radicular component.
- The MILD procedure if there is also lumbar central canal stenosis from ligamentum flavum hypertrophy. (See my MILD complete guide.)
- Medial branch RFA if there is also facet-joint arthritis driving pain.
- Spinal cord stimulation (rare salvage option for patients with persistent pain after Intracept). (See my SCS vs DRG vs PNS guide.)
For most isolated vertebrogenic pain patients, Intracept alone is the right answer.
Risks and complications
The complication rate is low, comparable to a complex epidural injection:
- Bleeding at the entry site: usually self-limited.
- Local infection: under 1 percent.
- Nerve root irritation: temporary, typically resolves in days to weeks.
- Vertebral fracture: rare, mainly a concern in severe osteoporosis.
- Inadequate pain reduction: about 25 to 35 percent of patients do not get adequate benefit. Re-check candidacy before considering escalation.
- Anesthesia-related: rare with conscious sedation.
Frequently Asked Questions
How long does the benefit last?
The 5-year INTRACEPT trial follow-up shows sustained benefit at 5 years for most responders. Vertebrogenic pain is unusual in interventional pain medicine in that the nerve, once ablated, takes years to regenerate (if at all). The durability is among the best in the field.
Will I need a fusion later?
Most patients who respond to Intracept never need a fusion. By definition, Intracept addresses one specific pain generator. If you respond, that generator is silenced; the rest of your spine is unchanged.
Can I have Intracept if I have had spine surgery before?Yes, generally. Prior fusion at adjacent levels is fine. Prior fusion at the target level itself usually disqualifies that level. Prior laminectomy or discectomy: usually fine. We check on a case-by-case basis.
Will Medicare cover it?
For qualifying patients (the criteria above), yes. Medicare LCDs since 2022 have been increasingly favorable.
Can I have Intracept on blood thinners?
Most blood thinners are paused 5 to 7 days before Intracept. Some cannot safely be paused; in those cases I adjust the technique or coordinate with cardiology.
What if Intracept does not work for me?
You have not burned any bridges. Intracept does not change your anatomy in a way that prevents future treatment. Options include re-evaluation for a different pain generator, RFA for facet-mediated pain, MILD if there is concurrent stenosis, or spinal cord stimulation for refractory cases.
Can I have Intracept at multiple levels?
Yes. Most patients have 1 to 2 levels treated in one session. Three levels in one session is possible but less common.
