Doctor is recommending I undergo the Intracept procedure. Are there any downsides I should know about?

I've been experiencing chronic lower back pain for approximately 15 months now. I have been in PT for 5 months and while I have regained strength and some utility, I still experience sharp pain during certain transition movements (sitting up, standing up, bending over, leaning back) and sitting for prolonged periods of time. I can walk around upright all day with almost no pain and if I take ibuprofen or diclofenac the pain becomes much more tolerable.

I had an MRI which revealed "multilevel degenerative changes of lumbar spine worse at L5-S1. Broad-based disc bulge with central protrusion and annular tear. Encroachment upon the left neuroforamen. No spinal canal stenosis. Modic type I/active degenerative changes at L5-S1.

I saw a spinal orthopedist who said my age/symptoms/imaging does not indicate any surgery is needed but that if PT hasn't resolved my pain yet it likely isn't going to go away on its own and referred me to a interventional radiologist within the same health network.

The interventional radiologist said my pain is most likely coming from from the endplates around my L5-S1 disc and that I checked every box for the Intracept procedure which has shown to be very effective at relieving pain in patients like myself.

One thing that has me hung up however is how commercialized the procedure is. The interventional radiologist provided me with a folder filled with fancy marketing materials like you would expect to pick up at a conference booth. Last night I received an email from Relievant (which is the for-profit company that I understand invented the procedure and sells the tools used to conduct it) saying that they have assigned me a case manager who will work with my insurance company to ensure they approve it. Reading from what some others on reddit who have undergone the procedure have said I understand it costs anywhere in the ballpark of $15-30k without insurance.

To others who have undergone the procedure- is all this the normal experience? I've never worked with a for-profit entity to petition my insurance provider for coverage before.

While I agree it appears much less invasive and risky than disc replacement/fusion, the idea of hammering into my vertebrae and burning nerves inside as a second line of treatment after PT has failed seems a bit extreme.

Looking for any and all input, especially if there are any healthcare providers on here who can present a more clinical opinion. (For some reason I can't help but think my doctor isn't getting some kind of kickback from Relievant since he seems so eager to perform the procedure)
