I’m not aware of any practices truly abusing PNBs on Medicare patients. The reimbursement just isn’t worth it. The most likely explanation is that the powers that be know interventional pain is overutilized so as a general category it’s on the chopping block, but stim and the other true cost drivers have multiple billion dollar companies lobbying for them. So, cool, I can SCS anyone with refractory trunk and/or limb pain at $30,000 a pop, but god forbid I do therapeutic ONBs on a few patients with C2-7 fusions or occipital headaches for $80. Oh, and even that will get cut in half next year if I do it at the same time as an office visit.
