<unk>  or<unk> <unk>  medicine is a medical subspecialty defined by the National Uniforms Claims Committee (NUCC) as, " invasive interventions such as the discipline of medicine devoted to the diagnosis and treatment of<unk>  related disorders principally with the application of<unk>  techniques in managing sub acute, chronic, persistent, and intractable<unk> , independently or in conjunction with other modalities of treatment". Medicare Payment Advisory Commission (MedPAC) defined<unk>  techniques as, "minimally invasive procedures including, percutaneous precision needle placement, with placement of drugs in targeted areas or ablation of targeted nerves; and some surgical techniques such as laser or endoscopic diskectomy, intrathecal infusion pumps and spinal cord stimulators, for the diagnosis and management of chronic, persistent or intractable<unk> ". Minimally invasive interventions such as facet joint injections, nerve blocks (interrupting the flow of<unk>  signals along specific nervous system pathways), neuroaugmentation (including spinal cord stimulation and peripheral nerve stimulation), vertebroplasty, kyphoplasty, nucleoplasty, endoscopic discectomy, and implantable drug delivery systems are utilized in managing subacute or chronic<unk> . Much of<unk>  falls under the umbrella of<unk>  radiology, but not all; some of the procedures may be done by health professionals whose job titles do not invoke<unk>  radiology specifically.
