Spinal Radiofrequency Ablation

It is another name for spinal radiofrequency ablation of the facet joints. Medicare’s coverage policy notes that the terms radiofrequency ablation and radiofrequency neurotomy are used interchangeably; both describe using radiofrequency heat to stop the medial branch nerves from carrying pain signals from the facet joints^[3]. “Facet rhizotomy” is an older term for the same idea, and New York’s workers’ compensation guidelines list all three names together^[4].

The blocks show whether the nerves that RFA would treat are really carrying your pain. A medial branch block numbs those nerves for a few hours; strong relief points to the facet joints, while little relief suggests another source^[1]. Medicare in New York requires two separate blocks, at least two weeks apart, each giving at least 80% relief of your usual pain before it covers RFA^[3].

Tell us about all your medicines and about any pacemaker, defibrillator or stimulator, which needs advance planning^[1]. Lower- and mid-back RFA is considered low bleeding risk, so many people continue their blood thinners^[7] — but never stop or keep one without checking with the prescribing doctor. Follow any fasting instructions if sedation is planned, and arrange a ride home.

No — most patients are awake, with numbing medicine and sometimes a light relaxing medicine. You will feel pressure, warmth or an ache as the needles are placed. Staying awake lets you tell the physician what you feel during nerve testing, which helps keep the needle away from nerves that control movement^[1]. Medicare’s New York policy considers routine deep sedation or general anesthesia for facet RFA not medically necessary and allows moderate sedation only in documented special cases^[3].

For the first 24 hours, do not drive, and avoid strenuous activity and heavy lifting. You do not need prolonged bed rest — rest that day, then gradually return to normal activities, usually within a day or two^[12]. Use ice for 20 minutes at a time for soreness. Call us if you develop fever, increasing redness or swelling, or new weakness or numbness in an arm or leg^[12].

Relief usually lasts many months but is not lifelong. Cleveland Clinic reports relief commonly lasts 6 to 12 months and sometimes a few years^[12]; New York’s workers’ compensation guideline notes that successful treatment usually provides six to nine months of relief^[4]. In a placebo-controlled neck trial, the median time before pain returned was 263 days^[2]. Some people get only limited relief, and pain can return as the nerve regrows.

RFA can be repeated when pain returns, as long as the earlier treatment helped. Medicare in New York covers a repeat at the same site after at least 50% improvement in pain or function lasting six months, and pays for no more than two RFA sessions per spinal region in a rolling 12 months^[3]. New York workers’ compensation guidelines also allow repeat RFA up to twice a year^[4]. Repeat treatments usually work about as well as the first^[1].

Spinal RFA is generally safe when patients are carefully selected and X-ray guidance is used, but it is not risk-free. The most common problems are temporary soreness and nerve irritation; infection and nerve root injury are uncommon^[1][12]. You may see RFA called “FDA-approved,” but that is not accurate: procedures are not approved like drugs. The radiofrequency generators used are FDA-regulated Class II medical devices cleared through the 510(k) premarket process^[6].

Medicare covers spinal RFA in New York when strict criteria are met: at least three months of pain despite conservative care, two medial branch blocks with at least 80% relief, and frequency limits^[3]. Commercial plans often require prior authorization. New York workers’ compensation guidelines recommend RFA in select patients after two successful blocks^[4][5]. No-fault claims follow their own rules. We accept many plans, including Medicare, workers’ compensation and no-fault, and verify your benefits before scheduling.

If RFA gave little relief, the facet joints may not be your main pain source, and your physician will look again at the discs, SI joints or nerves. Options include continued exercise therapy, a facet joint injection, an SI joint injection, basivertebral nerve ablation for certain vertebral endplate pain, or endoscopic rhizotomy. If pain returns after good relief, repeat RFA is often effective^[1].

For confirmed facet pain, RFA usually gives longer relief than a steroid injection. A facet joint injection places medicine, often a steroid, inside the joint, and relief is often short-lived; RFA treats the nerves and is designed to last months. A Cochrane review found low- to very-low-quality evidence that facet RFA relieves pain better than steroid injections in the short, medium and long term^[8].
