Medical Necessity Determination for Permanent Spinal Cord Stimulator Implantation

Critical Missing Documentation That Precludes Medical Necessity

The American Society of Anesthesiologists explicitly requires favorable psychological evaluation, absence of untreated psychiatric comorbidity, or current treatment in a multidisciplinary pain management program before SCS trial 1
No documentation exists confirming psychological clearance, motivation, or capability to follow medical recommendations 2
The American Society of Anesthesiologists requires documentation of trials of first-line neuropathic pain medications before considering SCS 1
The Mayo Clinic recommends documenting trials of gabapentin, pregabalin, duloxetine, or tricyclics before SCS, as part of conventional medical management including appropriate analgesics 1
Formal in-person physical therapy with a licensed physical therapist for a minimum of 6 weeks within the past year is required, with documentation including dates of service, specific interventions, patient response, and therapist assessment 2

The American Society of Anesthesiologists recommends considering pulsed radiofrequency treatment adjacent to the dorsal root ganglion before proceeding to SCS 1
Spinal cord stimulation is specifically recommended for therapy-resistant radicular pain in the context of Failed Back Surgery Syndrome 1
The patient's diagnosis of persistent pain following multilevel lumbar fusion is an established indication for SCS, according to the American Society of Anesthesiologists guidelines 2

SCS demonstrates significant advantages over reoperation for persistent pain after back surgery, with 47-59% of FBSS patients achieving ≥50% pain relief at long-term follow-up, as reported by the American College of Neurosurgery 2
A successful trial showing at least 50% pain relief is required before permanent implantation, according to the American College of Neurosurgery 2

Hardware-related complications, including lead migration and connection issues, occur in 10-29% of cases, as reported by the American Society of Anesthesiologists 1
Infection risk must be carefully considered, with reported rates of 10-29%, according to the American Society of Anesthesiologists 1
Wound dehiscence followed by infection occurs in 14% of cases, as reported by Neurosurgery 3
Lead migration occurs in 9% of cases, as reported by Neurosurgery 3

The American Society of Anesthesiologists requires formal psychological evaluation confirming absence of untreated psychiatric comorbidities, substance use disorders, and demonstrating patient motivation and capability 1, 2
The American Society of Anesthesiologists requires documented trials of first-line neuropathic pain medications including specific medications, dosages, duration, and reasons for discontinuation (gabapentin, pregabalin, duloxetine, or tricyclic antidepressants) 1
The American Society of Anesthesiologists requires formal physical therapy documentation including dates of service (minimum 6 weeks), specific interventions performed, patient response, and therapist assessment 1, 2
The American Society of Anesthesiologists requires baseline validated outcome measures including Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores 1, 2

For radiculopathy, gabapentin is associated with small, short-term benefits and should be formally trialed with documentation, as recommended by the American College of Physicians 4

The evidence base for SCS has limitations, but this does not diminish the value of the therapy when appropriate selection criteria are met, according to the Congress of Neurological Surgeons 5
The lack of high-quality randomized controlled trials with sham stimulation does not negate the established clinical practice standards for patient selection, as noted by the American Association of Neurological Surgeons 5, 6

The patient has undergone injections in the right shoulder without benefit, and has significant pulmonary disease requiring 2-3L oxygen at baseline and 4L with activities, which creates substantial surgical risk for SCS implantation 7
The patient's oxygen dependence and pulmonary compromise significantly increase infection risk, with wound complications followed by infection occurring in 14% of cases under normal circumstances 7
A multidisciplinary vascular/surgical team should formally assess whether the patient can safely undergo the implantation procedure, given her high pulmonary risk and inability to position prone 7
Pulmonary clearance alone is insufficient; the surgical team must confirm they can safely perform the procedure given positioning limitations 7
Recent physical therapy documentation must include dates of service, specific interventions, patient response, and therapist assessment, and should specifically address whether the patient can tolerate exercises and document any limitations 7
