Blue Cross NC Dorsal Column (Lumbar) Neurostimulators: Trial or Implantation prior authorization requirements (2026)

Medical-necessity criteria Blue Cross NC generally applies

Spinal Cord Stimulation (including burst, high frequency, and traditional stimulation methods) - Stimulator Trial: "may be considered medically necessary when ALL of the following criteria are met: The patient has chronic intractable neuropathic pain of the trunk and/or limbs associated with at least ONE of the following conditions: Lumbosacral arachnoiditis as documented by high levels of protein in the cerebrospinal fluid and/or imaging (MRI or myelography); Nerve root injuries that are post-surgical after a spine surgery (e.g., failed back surgery syndrome [FBSS]); Complex regional pain syndrome (CRPS), type I or type II ... which meets diagnostic criteria for CRPS (as per Budapest criteria); Painful diabetic neuropathy (PDN) when ALL of the following criteria are met: Evidence of painful PDN of at least 12 months; Lower limb pain intensity of >= 5 on the VAS scale; Objective evidence for presence of neuropathy and severity: moderate-severe neuropathy on EMG/NCS; Confirmation of PDN diagnosis by at least one other specialist (e.g., neurologist); BMI <= 35; HbA1c <= 10%; Daily morphine equivalents of 120 mg or less; Documented medical clearance as candidate for the procedure; Other causes of neuropathy have been ruled out; Optimization of medical management ...; Failed trial (or documented intolerance) to multiple pharmacologic agents in at least 2 categories ...; Absence of upper limb pain intensity of >= 3 on a VAS scale; Severe pain and disability with documented pathology or an objective basis for the pain; Dorsal column stimulation is being used as a late or last resort after documented failure of at least 6 consecutive months of physician-supervised multimodal conservative management; Failed trial of regional sympathetic blocks in the case of CRPS; There is no evidence of existing untreated drug addiction; The patient has been evaluated by a pain management specialist prior to implantation; ... At least one surgical opinion has been obtained to ensure that the patient does not have a surgically correctable lesion (excludes CRPS and PDN); Documentation of an evaluation by a licensed mental health provider within 6 months of a stimulator trial request ... that confirms no evidence of an inadequately controlled mental health problem (e.g., alcohol or drug dependence, depression, psychosis) that would negatively impact the success of a spinal cord stimulator or contraindicate its placement." "Spinal cord stimulator trial must be performed with percutaneously placed leads except under certain situations." Stimulator Implantation (Permanent): "The patient meets ALL of the criteria for a stimulator trial; A stimulator trial of at least 3 days duration has been performed; Documented pain reduction and functional improvement following the stimulator trial with at least a 50% reduction of target pain or analgesic medication use, and specific evidence of improved function." Replacement/revision/removal: hardware complication (lead migration, infection, painful generator site), end of life for battery change, patient intolerance, new neurologic deficits, or a planned MRI/AICD where the stimulator is contraindicated.

Situations to verify before submitting

Blue Cross NC may not cover Dorsal Column (Lumbar) Neurostimulators: Trial or Implantation in these situations. Verify against the current policy rather than assuming a denial:

• {"text":"Exclusions: \"Use of spinal cord stimulation for the treatment of critical limb ischemia to forestall amputation, refractory angina pectoris, heart failure, and cancer-related pain; Repeat trial of spinal cord stimulation if the initial trial failed; Replacement of a conventional spinal cord stimulator with a burst, high frequency, or dorsal root ganglion stimulator in the absence of an indication for stimulator removal; Dorsal root ganglion neurostimulation for any non-CRPS lower extremity indication; Dorsal root ganglion neurostimulation in patients with CRPS lower extremity who currently have a functioning spinal cord stimulator or who have previously failed spinal cord stimulation therapy; Simultaneous placement of a dorsal column and dorsal root ganglion stimulator; Chronic, nonsurgical low back pain with or without a neuropathic component in patients with no history of prior lumbar spine surgery.\"","source":"https://guidelines.carelonmedicalbenefitsmanagement.com/interventional-pain-management-2026-06-14/"}

How to submit

• Method: Prior authorization is delegated to Carelon Medical Benefits Management for spine surgery, joint surgery, interventional pain management, and small joint surgery (Commercial Fully Insured since 2023-10-01; ASO groups only if the group elected the program, effective 2025-01-01 - verify by member ID on the Carelon portal or via the number on the member ID card).
