## Quick answer

Medicare pays an average of about $282 per facet joint nerve ablated, but a typical two-level lumbar treatment lands near $470 on Medicare and $1,500 to $4,000 on commercial insurance once facility fees and imaging guidance are added.

## What it is

Spine radiofrequency ablation, often called facet joint RFA or medial branch neurotomy, is a needle-based procedure that uses heat to deactivate the small nerves that carry pain signals from arthritic spinal joints. A physician inserts thin needles through the skin of your back under live X-ray guidance, touches them to the target nerves, and then passes a radio-frequency current through the needle tip. The heat creates a small lesion on the nerve. Once that nerve is off, it cannot send pain signals from the joint for months.

- **Time on the table:** roughly 30 to 60 minutes for the ablation itself, plus check-in and recovery.
- **Anesthesia:** usually local numbing plus light IV sedation. General anesthesia is rare.
- **Setting:** ambulatory surgery center, hospital outpatient department, or pain physician's office procedure suite. No overnight stay.
- **Incision:** none. Only needle punctures.
- **Imaging:** fluoroscopy (live X-ray) is standard and is billed with the procedure.

The procedure comes in several flavors depending on which part of the spine is treated. Lumbar and sacral ablations (CPT 64635 and 64636) are by far the most common and account for the majority of the 684,756 Medicare services in the latest data. Cervical and upper-thoracic ablations (64633, 64634) are less frequent but clinically similar. Sacroiliac joint ablation (64625) targets the joint between the spine and pelvis. Basivertebral nerve ablation (64628, marketed as Intracept) is a different procedure entirely: it uses a device to burn a nerve inside the vertebral bone for vertebrogenic low back pain, and its Medicare payment is roughly ten times higher because of the RVU structure and device cost.

## When it is done

Radiofrequency ablation is a middle step on the chronic back and neck pain ladder. It is not the first thing doctors try, and it is not for pain coming from a herniated disc or pinched nerve root. It targets pain that originates in the facet joints, the small paired joints that let your spine bend and rotate. Before ablation, your physician should have confirmed the facet joints are the real source with one or two diagnostic medial branch blocks that each produced at least 50% to 80% temporary relief.

Your doctor may recommend this when:

1. You have axial back or neck pain (not leg or arm pain) that has lasted more than three months.
2. Physical therapy, NSAIDs, and activity modification have not provided lasting relief.
3. One or two diagnostic facet blocks confirmed the facet joints are the pain generator.
4. Imaging or exam points to facet arthritis rather than disc, nerve root, or sacroiliac pathology.
5. You are not ready for, or not a candidate for, spinal fusion surgery.
6. You want an option that can be repeated every 6 to 12 months if needed.

Alternatives include continued conservative care, corticosteroid injections, spinal cord stimulation, and for some patients, surgical fusion. RFA sits between injections and surgery on both cost and invasiveness.

## What you pay

What you actually pay depends on four things: how many levels are treated, whether it is one-sided or both sides, where the procedure is done, and what insurance you have. Medicare's rates are anchored to the national fee schedule and are the most predictable number on this page. Commercial insurance is usually 2x to 4x the Medicare rate for the same codes, and hospital-based outpatient billing can push commercial total charges to $3,000 or more per session for a multi-level ablation.

**If you're on Medicare:**

- This is a Part B procedure. You pay the annual Part B deductible first ($257 in 2025), then 20% coinsurance on the Medicare-allowed amount.
- For a typical bilateral two-level lumbar RFA, Medicare's allowed amount is roughly $1,200 to $1,600 including facility fee and imaging, so your 20% share is about $240 to $320 per session if the deductible is already met.
- A Medigap (supplemental) plan usually covers that 20%, leaving you with little or nothing.
- Medicare Advantage plans vary. Most cover RFA but may require prior authorization and use their own copay structure.

**If you have commercial insurance:**

- Expect a total billed charge of $1,500 to $5,000 per session and an allowed amount of $800 to $2,500 depending on network contracts.
- Your out-of-pocket usually runs $200 to $1,200 per session depending on your deductible and coinsurance.
- Nearly every commercial plan requires prior authorization and proof that two diagnostic medial branch blocks produced meaningful relief.
- Watch for the annual out-of-pocket maximum. If you are getting fusion, an epidural, and RFA in the same year, the RFA may be the session that hits your OOP cap.

**If you're uninsured or paying cash:**

- Ambulatory surgery centers and pain clinics often quote a bundled cash-pay price of $800 to $3,500 per session that includes the physician fee, facility use, and imaging guidance.
- Hospital-billed charges without insurance can exceed $5,000, so an ASC or office-based negotiated rate is usually the better deal.
- Ask for hospital financial assistance if you are close to the income threshold; many nonprofit hospitals write off RFA for qualifying patients.
- Some practices offer a series rate if you are clearly a candidate for repeat treatments.

## Anatomy of the bill

A facet RFA bill typically has four to five separate line items. Seeing them on one invoice is unusual; expect statements from the physician group, the facility, and possibly a separate anesthesia provider to arrive at different times.

- **Physician (professional) fee:** the surgeon or pain physician bills under CPT 64633 through 64636 depending on which spinal region and how many levels. This is the core fee and runs $130 to $350 per level on Medicare, often 2x to 4x that on commercial plans.
- **Facility fee:** the site where the procedure happens bills separately. Hospital outpatient departments charge the most, ambulatory surgery centers charge less, and office-based suites roll the technical cost into the physician bill. Facility fees can equal or exceed the physician fee at a hospital.
- **Imaging guidance:** fluoroscopy is required and is usually bundled into the RFA codes in 2020 and later, so you should not see a separate CPT 77003 charge. If you do, it is a billing error worth challenging.
- **Sedation and anesthesia:** most RFAs use light IV sedation by the same physician or a nurse, which is bundled. If a separate anesthesiologist or CRNA provides monitored anesthesia care, that is a separate bill of $200 to $800 depending on time and insurance.
- **Post-procedure visit:** a short follow-up at 2 to 4 weeks to gauge relief is usually billed as a standard office visit (CPT 99213 or 99214), $75 to $200.

Diagnostic medial branch blocks done before the RFA are their own procedure (CPT 64490 through 64495) and are billed on separate dates of service. Patients often forget the two prior blocks when budgeting, which can triple the true episode cost.

## Cost by state

There is a wide geographic spread in what Medicare pays for spine RFA, even though the national fee schedule is the foundation. West Virginia is the cheapest state in the latest data at $115.72 weighted-average payment, while Connecticut is the priciest at $331.74. That is nearly a 3x range. High-volume states include Florida (123,986 services), Texas (98,138), California (58,230), and Arizona (54,242), reflecting both population and the density of pain medicine practices.

Why costs vary by state:

- **Medicare GPCI adjustments:** the geographic practice cost index raises payments in high-cost-of-living areas like the Northeast and Bay Area and lowers them in Appalachia and the rural Midwest.
- **Mix of codes performed:** states with more basivertebral (Intracept) procedures show higher averages because that single code pays 10x more than a standard facet RFA.
- **Commercial negotiation power:** large hospital systems in consolidated markets can negotiate commercial rates 3x to 5x Medicare, whereas competitive metros with many ASCs see tighter commercial pricing.
- **State surprise-billing and ASC licensing laws:** states with strong ASC networks (Florida, Texas, Arizona) tend to have lower total episode costs because more procedures shift out of hospital outpatient departments.

## Office vs facility

Unlike most spine procedures, facet RFA splits fairly evenly between settings. Medicare data shows 425,468 services in a facility (hospital outpatient or ambulatory surgery center) and 259,288 in office-based procedure suites. Interestingly, the office-based Medicare payment to the physician is slightly higher ($311.45) than the facility payment ($297.56). That difference exists because when the physician performs RFA in their own office, they bill for both the professional and technical components.

For the patient, the total cost story is different because facility fees only show up at hospitals and ASCs.

- **When an office suite makes sense:** cash-pay patients, simple one- or two-level lumbar RFAs, no heavy sedation needed. Total cost is usually lowest.
- **When an ambulatory surgery center makes sense:** you want deeper sedation or need multiple complex levels, and commercial insurance covers ASC facility fees well.
- **When a hospital outpatient department makes sense:** you have significant cardiac or respiratory comorbidities that require hospital-grade monitoring, or your surgeon only operates at that facility. Expect the highest total bill.

## Who performs the procedure

Spine RFA is overwhelmingly done by pain medicine physicians. In the Medicare data, four specialties perform more than 95% of the volume: pain management (331,576 services), anesthesiology (260,522), interventional pain management (230,976), and physical medicine and rehabilitation (212,289). These doctors typically did a residency in anesthesiology or PM&R followed by a one-year pain medicine fellowship.

What to look for when choosing a specialist:

- **Fellowship training:** ask whether the physician completed an ACGME-accredited pain medicine fellowship and is board-certified in pain medicine.
- **Volume:** a physician who performs dozens of RFAs per month develops better needle technique and produces more complete lesions. Ask how many they did last month.
- **Diagnostic discipline:** a good pain physician will not ablate until you have had one or ideally two diagnostic medial branch blocks with clear relief. If someone offers RFA on the first visit, that is a red flag.
- **Fluoroscopy habits:** confirm they use live X-ray guidance for every RFA and that you can see the images in your chart.
- **Repeat-procedure plan:** ask what happens if it does not work, or if relief lasts only 3 months. A thoughtful physician has a stepwise plan, not just another ablation.

A small number of diagnostic radiologists (37 providers), neurologists (37), and orthopedic surgeons (46) appear in the data. These are typically either assistant roles or physicians who did additional pain training; they are not the common path to getting this procedure.

## How to shop for the best price

Spine RFA is one of the most shoppable spine procedures because volumes are high, many practices offer it, and prices vary wildly. A little homework can cut your bill in half.

1. **Get a Good Faith Estimate in writing.** Federal law requires facilities to provide one to self-pay and uninsured patients. Ask for one even if you have insurance; it is useful for predicting coinsurance.
2. **Confirm every billing party is in-network.** Verify the physician, facility, and any anesthesia provider separately. Ask who will bill for sedation before you walk in.
3. **Compare hospital outpatient versus ambulatory surgery center versus office suite.** For the same CPT codes, ASC and office prices are often 30% to 60% lower than hospital outpatient pricing.
4. **Ask for a bundled cash-pay rate.** Most pain clinics quote a single bundled fee for cash patients that covers physician, facility, and imaging. That rate is almost always lower than the sum of insurance-billed components.
5. **Confirm imaging is bundled.** Fluoroscopy is included in the 2020-and-later RFA codes. If you see a separate charge for CPT 77003, challenge it.
6. **Budget for the whole episode, not just the ablation.** You will have two diagnostic medial branch blocks before RFA and a follow-up visit after. Ask for prices on all three.
7. **Ask about financial assistance and payment plans.** Most nonprofit hospitals have written charity care policies that cover pain procedures for patients under 300% to 400% of the federal poverty line.

Red flags to watch for: vague verbal estimates that say only "about a thousand dollars," refusal to put a price in writing, bundled quotes that exclude imaging or sedation, and any office that books you for RFA without doing diagnostic blocks first.

## Surprise billing risks

Surprise bills for spine RFA usually come from three places: a separate anesthesia provider, a facility that is out-of-network even though the physician is in-network, and unbundled fluoroscopy charges that sneak onto the bill.

Most common surprise-billing sources:

- **Anesthesiologist or CRNA:** if your pain physician uses a separate anesthesia provider for monitored anesthesia care, that provider may not be in your network even if the physician is.
- **Facility mismatch:** your pain physician may be in-network while the ambulatory surgery center they use is not, producing a separate out-of-network facility bill.
- **Unbundled imaging:** fluoroscopy guidance is included in the RFA code. A separate charge for CPT 77003 is a billing error.
- **Duplicate billing of diagnostic blocks and RFA:** occasionally a clinic bills both a medial branch block and an RFA on the same day; most payers will deny the block portion.
- **Pathology:** rare for RFA but can appear if any tissue is incidentally sent.

If you get a surprise bill:

- Do not pay until you have verified it. Request a fully itemized statement with CPT codes.
- Check whether the provider and facility were in-network on the date of service; if not, you are likely protected by the federal No Surprises Act (2022) for emergency and most non-emergency facility care.
- File a dispute through cms.gov/nosurprises or call the No Surprises Help Desk at 1-800-985-3059.
- Escalate to your state insurance commissioner if the provider will not correct an in-network billing error.

## Total recovery cost

Recovery from facet RFA is fast compared to any spine surgery, but pain relief itself is slow. Most patients go home the same day and can return to a desk job in one or two days. Full ablation pain (a burning, achy soreness at the needle sites) resolves within 1 to 2 weeks. The real benefit, the relief of the underlying facet joint pain, typically takes 2 to 6 weeks to develop because the nerve has to die back completely. Relief then lasts on average 6 to 12 months before the nerve regrows and pain returns.

Add-on costs to budget for:

- **Two diagnostic medial branch blocks beforehand:** $150 to $600 total on Medicare, $500 to $2,500 total on commercial insurance.
- **Physical therapy after ablation:** $40 to $120 per session on Medicare coinsurance, $20 to $75 copay on commercial, typical course of 6 to 12 sessions.
- **Over-the-counter pain care:** ice, NSAIDs, topical analgesics, roughly $30 to $80 for the first two weeks.
- **Time off work:** usually 1 to 2 days for office workers, 3 to 7 days for manual labor.
- **Repeat RFA in 6 to 12 months:** if the first round worked, most pain physicians will repeat when pain returns; plan for the same episode cost annually.
- **Follow-up imaging or consults:** occasional MRI if pain changes character, roughly $300 to $700 per scan.

Put together, the realistic episode cost (two blocks plus RFA plus PT plus follow-up) is usually 30% to 60% more than the single RFA sticker price. If relief is durable and you only repeat every 12 months, total annual cost of managing facet pain with RFA is typically $1,500 to $5,000 on commercial insurance and $400 to $1,200 on Medicare with supplemental coverage.

## Frequently asked questions

### How much does facet joint radiofrequency ablation cost with insurance?

Most commercially insured patients pay $200 to $1,200 out of pocket per session after deductible and coinsurance. On Medicare with a Medigap plan, the out-of-pocket cost is often under $50. On original Medicare without supplemental coverage, expect roughly 20% of the allowed amount, or $240 to $320 for a typical bilateral two-level lumbar RFA.

### Does Medicare cover spine radiofrequency ablation?

Yes. Medicare Part B covers facet RFA (CPT 64633 through 64636) and sacroiliac RFA (64625) when prior diagnostic medial branch blocks have shown meaningful relief. Medicare also covers basivertebral nerve ablation (64628) for appropriate patients. Prior authorization is not required in original Medicare but is common in Medicare Advantage.

### How long does pain relief last after RFA?

On average 6 to 12 months. The nerve grows back, and when it does the pain usually returns. Many patients repeat the procedure annually. A minority of patients get longer-lasting relief, and some get little or no benefit even after positive diagnostic blocks.

### Is RFA outpatient or does it require a hospital stay?

It is strictly outpatient. The procedure takes 30 to 60 minutes, you are typically awake with light sedation, and you go home within an hour or two. No hospital stay is required, and most patients are back to desk work in 1 to 2 days.

### What's the difference between lumbar RFA and basivertebral nerve ablation?

They are different procedures despite both using radiofrequency heat. Lumbar facet RFA (64635, 64636) treats arthritis pain from the small joints of the spine by burning nerves outside the bone. Basivertebral nerve ablation (64628, Intracept) drills into the vertebral body to burn a nerve inside the bone for vertebrogenic low back pain coming from the vertebral endplates. The Intracept procedure is more invasive and costs about ten times more on Medicare.

### How do I avoid a surprise bill for RFA?

Confirm in writing that the physician, the facility, and any separate anesthesia provider are all in your network. Ask for a Good Faith Estimate. Request an itemized bill afterward and challenge any separate fluoroscopy charge; imaging is bundled into the RFA codes. If a surprise bill shows up, file a dispute at cms.gov/nosurprises.

### What's the cheapest way to get RFA?

Office-based or ambulatory surgery center suites are usually cheapest, and a bundled cash-pay rate from a pain clinic can run $800 to $2,000 for a simple one- or two-level session. Hospital outpatient departments are the most expensive. Ask three local pain clinics for a written bundled quote before scheduling.

### Where does this cost data come from?

The Medicare figures on this page are from the CMS Medicare Physician and Other Practitioners Public Use File, covering 684,756 RFA services across 5,957 providers. Commercial and cash-pay ranges are typical market rates, not averages from a claims database, because no public dataset reports commercial prices the way Medicare reports its own.
