CLINICAL STAGE / CARE PATHWAY
Patient is currently in the therapeutic intervention phase of care with chronic vertebrogenic low back pain persisting greater than 6 months despite conservative non-surgical management, demonstrating clinical findings supporting progression to thermal destruction of the intraosseous basivertebral nerve (BVN) for symptom relief.
– Sequencing logic:
Thermal destruction of the BVN is appropriate after at least 6 months of failed conservative therapy and diagnostic confirmation by MRI showing Modic Type 1 or 2 changes consistent with vertebrogenic pain.
ICD-10 / DIAGNOSIS SUPPORT
Diagnosis support includes vertebrogenic low back pain with Modic changes on lumbar MRI consistent with the degenerative endplate inflammatory process causing chronic low back pain.
The documented diagnosis correlates with patient presentation of axial low back pain without radicular symptoms, supported by imaging and failure of prior treatment.
– Example ICD-10 options:
M54.51 – Vertebrogenic low back pain
M47.816 – Spondylosis without myelopathy or radiculopathy, lumbar region
M47.817 – Spondylosis without myelopathy or radiculopathy, lumbosacral region
SUBJECTIVE / HPI SUPPORT
Patient reports chronic midline, deep, aching, and burning low back pain for greater than 6 months, often with intermittent electrical shock sensations, worsening with spinal flexion, sitting, standing, and general activity. Pain limits functional capacity including walking, sitting tolerance, sleeping, and work activities despite prior conservative therapies.
– Edit if needed:
greater than 12 weeks
greater than 6 months
axial lumbar pain
non-radicular pain
absence of lower extremity weakness or sensory deficits
CONSERVATIVE CARE / PRIOR TREATMENT
Patient has undergone at least 6 months of conservative management including physical therapy, home exercise programs, activity modifications, NSAIDs, cognitive behavioral approaches, chiropractic manipulation, epidural or facet injections, and pharmacotherapy without durable clinical improvement.
– Documentation tip:
Confirm duration and effectiveness of conservative care prior to procedural consideration.
OBJECTIVE / DIAGNOSTIC SUPPORT
MRI demonstrates Modic Type 1 and/or Type 2 changes in vertebral endplates from levels L3 to S1 consistent with vertebrogenic pain etiology. No evidence of significant spinal stenosis, nerve root compression, fracture, tumor, or infection present to explain symptoms.
Physical examination reveals no radicular findings or neurological deficits, correlating with non-radicular vertebrogenic pain syndrome.
ASSESSMENT
Assessment: Chronic vertebrogenic low back pain refractory to conservative treatment. Clinical evaluation and radiographic findings support medical necessity for thermal ablation of the intraosseous basivertebral nerve to target the nociceptive pain source within vertebral endplates.
PLAN / NEXT STEP
Plan: Proceed with thermal destruction of the intraosseous basivertebral nerve at affected vertebral levels guided by fluoroscopy, applying radiofrequency ablation to the BVN at 85 degrees Celsius for approximately 15 minutes per level, under moderate sedation or general anesthesia. Risks, benefits, and alternative treatments reviewed with the patient.
– Edit if needed:
Lumbar levels L3-S1
Right-sided
Left-sided
Bilateral
PROCEDURE-SPECIFIC CLINICAL REQUIREMENTS
Patient demonstrates chronic low back pain of at least 6 months duration with documented functional impairment assessed by validated pain and disability scales such as VAS, NRS, Oswestry Disability Index, or PROMIS. Failure of a minimum of 6 months of non-surgical management is documented.
MRI evidence of Modic Type 1 or Type 2 changes in vertebral endplates at one or more levels between L3 and S1 is required to confirm vertebrogenic pain source.
No contraindications present such as systemic infection, coagulopathy, severe cardiopulmonary compromise, prior surgery at intended levels (except certain resolved cases), osteoporosis with fragility fractures, or significant spinal deformity.
– Documentation tip:
Include baseline and pre-procedure pain scores and functional assessments.
FOLLOW-UP / RESPONSE DOCUMENTATION
Patient reports significant improvement in pain intensity, physical function, standing and walking tolerance, sleep quality, and activities of daily living after thermal destruction of the intraosseous BVN compared to baseline.
Improvement is consistent with expected therapeutic response, typically assessed at follow-up visits post-procedure
– Edit if needed:
Greater than 50% reduction in pain intensity
Improvement sustained for months
Functional gains noted in validated disability scales
MISSING DOCUMENTATION CHECK
– Documentation items to confirm:
Symptom duration of chronic low back pain
Validated pain and disability scale scores
Evidence of failure of conservative treatment of at least 6 months
MRI confirming Modic Type 1 or 2 changes at L3-S1
Exclusion of alternative non-vertebrogenic pathologies
Physical exam confirming absence of radiculopathy or neurological deficits
Baseline pain and function scores pre-procedure
Levels intended for BVN ablation
APPEAL / PEER-TO-PEER CLINICAL SUPPORT
The requested thermal destruction of the intraosseous basivertebral nerve is clinically supported by the patient’s documented chronic vertebrogenic low back pain, validated functional impairment, failure of extensive non-surgical management, and MRI evidence of Modic changes. The clinical presentation and exam findings are consistent with vertebrogenic pain without radiculopathy, justifying progression to this therapeutic intervention.
This procedure is an appropriate next step in the treatment pathway based on the patient’s diagnosis, clinical status, and prior treatment response, supporting medical necessity.
COVERED PROCEDURES AND SERVICES
– Thermal destruction of the intraosseous basivertebral nerve (BVN) indicated for chronic vertebrogenic low back pain from L3-S1 vertebral bodies.
– CPT code 64628: thermal destruction including all imaging guidance for the first 2 lumbar or sacral vertebral bodies.
– CPT code 64629: each additional vertebral body ablated, reported separately in addition to primary procedure code.
– Up to 4 vertebral bodies may be treated in a single procedure; only one procedure per vertebral body per lifetime is allowed.
RELATED POLICIES
– Local Coverage Determination (LCD) L39420 version 4 governs coverage criteria and medical necessity standards.
