CLINICAL STAGE / CARE PATHWAY
Patient is currently in the therapeutic intervention phase of care for chronic vertebrogenic low back pain after documented failure of at least 6 months of conservative non-surgical management, with clinical and imaging findings supporting progression to thermal destruction of the intraosseous basivertebral nerve.
– Sequencing logic:
This procedure is considered after conservative care has failed and diagnostic imaging confirms Modic type 1 or 2 changes consistent with vertebrogenic pain. The patient has no contraindications and the treatment targets lumbar vertebral levels from L3 to S1.
ICD-10 / DIAGNOSIS SUPPORT
Diagnosis support includes clinically appropriate vertebrogenic chronic low back pain with Modic type 1 or 2 changes on MRI consistent with endplate degeneration and inflammation.
The documented diagnosis correlates with the patient’s chronic symptoms, imaging findings of vertebral endplate edema or fatty marrow replacement, and failed conservative treatment response.
– 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 greater than 6 months of chronic midline, deep, aching, burning low back pain that is progressive in nature, with intermittent electrical shock-like sensations. The pain is worse with spinal flexion, sitting, standing, and physical activities, and affects functional capacity including standing, walking, sitting tolerance, sleep quality, and daily activities despite prior treatment efforts.
– Edit if needed:
greater than 12 weeks
midline lumbar pain
intermittent shock sensation
worsened by flexion
no radicular symptoms
CONSERVATIVE CARE / PRIOR TREATMENT
Patient has undergone comprehensive non-surgical management for at least 6 months including physical therapy, activity modification, pharmacologic treatment with NSAIDs and muscle relaxants, chiropractic care, home exercise programs, cognitive support, and prior injection therapies without sustained functional improvement.
– Common conservative care examples:
Physical therapy
Home exercise program
NSAID therapy
Injection therapy – epidural or facet
Activity modification
OBJECTIVE / DIAGNOSTIC SUPPORT
Clinical examination and imaging studies including MRI demonstrate Type 1 or Type 2 Modic changes at vertebral levels L3 to S1 consistent with vertebrogenic pain.
No evidence of fractures, tumors, infections, significant deformity, or radiculopathy is identified that would better explain symptoms.
ASSESSMENT
Assessment: Chronic vertebrogenic low back pain associated with Modic type 1 or 2 changes and persistent functional impairment despite appropriate prior conservative care. Clinical findings, imaging correlation, and treatment history support medical necessity for thermal destruction of the intraosseous basivertebral nerve.
PLAN / NEXT STEP
Plan: Proceed with thermal destruction of the intraosseous basivertebral nerve at affected lumbar vertebral bodies (L3-S1) with imaging guidance, under appropriate sedation, targeting the involved vertebral levels based on clinical and radiologic correlation. Risks, benefits, and treatment alternatives have been reviewed and discussed with the patient.
– Edit if needed:
L3-L5 levels
L3-S1 levels
right-sided
left-sided
bilateral
PROCEDURE-SPECIFIC CLINICAL REQUIREMENTS
Patient has documented chronic low back pain of at least 6 months duration causing functional deficit measured by standardized pain or disability scales.
MRI confirms presence of Modic type 1 or 2 changes at 1 or more lumbar vertebrae from L3 to S1 indicative of vertebrogenic pain.
Patient has undergone at least 6 months of non-surgical management without adequate response.
No evidence of radicular symptoms, significant deformity, or exclusionary pathologies such as infection or tumor have been identified.
Contraindications such as prior lumbar spine surgery at the treatment level (except remote discectomy/laminectomy with resolved radicular symptoms), osteoporosis, and active infection have been ruled out.
FOLLOW-UP / RESPONSE DOCUMENTATION
Following the procedure, patient reports clinically meaningful improvement in axial low back pain intensity, functional capacities including standing and walking tolerance, sleep quality, and daily living activities compared to pre-procedure baseline.
Pain relief and functional improvement are consistent with expected therapeutic outcomes of basivertebral nerve ablation.
– Edit if needed:
greater than 50% pain relief
relief lasting several months
MISSING DOCUMENTATION CHECK
– Documentation items to confirm:
Symptom duration (≥ 6 months)
Functional limitation by pain/disability scale
Prior conservative care and response
MRI evidence of Modic 1 or 2 changes L3-S1
Exclusion of radicular or alternative pathologies
Physical and psychological screening documentation
Levels and laterality targeted
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, imaging evidence of Modic changes, failed conservative care, and absence of contraindications. The intervention represents a reasonable next step to address refractory symptoms and improve function.
The patient's clinical presentation, treatment history, and objective findings justify progression to intraosseous BVN ablation therapy within evidence-based care guidelines.
COVERED PROCEDURES
Thermal destruction (ablation) of the intraosseous basivertebral nerve (BVN) for chronic vertebrogenic lower back pain, including all imaging guidance. CPT code 64628 covers the first 2 lumbar or sacral vertebral bodies; CPT code 64629 covers each additional vertebral body and is reported in addition to 64628. Up to 4 vertebral bodies can be treated in one procedure, once per vertebral body per lifetime (L3-S1).
MEDICAL NECESSITY AND DIAGNOSTIC CRITERIA
Coverage requires all of the following:
– Chronic lumbar back pain ≥6 months with functional deficit documented by pain or disability scale at baseline
– Failure to improve after ≥6 months of non-surgical management (including physical therapy, chiropractic care, injections, medications, exercise, cognitive support)
– Absence of non-vertebrogenic causes of pain (e.g., fracture, tumor, infection, significant deformity) on clinical and imaging assessment
– MRI evidence of Type 1 or Type 2 Modic changes at one or more vertebrae between L3 and S1, indicating vertebral endplate inflammation or marrow changes
DOCUMENTATION REQUIREMENTS
Complete documentation of history, physical and psychological evaluations, imaging findings (MRI Modic changes), pain/disability assessments, and confirmation of conservative treatment failure must be maintained in the medical record to support medical necessity.
BILLING AND CODING GUIDANCE
– Use 64628 for initial two vertebral bodies treated with imaging guidance
– Use 64629 in addition to 64628 for each additional vertebral body ablated
– Only one ablation per vertebral body per lifetime allowed
– Imaging guidance is included in the procedure codes; do not bill separately
– Follow National Correct Coding Initiative (NCCI) edits and Medicare Claims Processing Manual guidance for radiology and procedural billing
– Ensure claims include all required information to avoid payment denials (per Social Security Act §1833(e))
EXCLUSIONS AND DENIAL RISK
Do not bill for patients with:
– Age ≤18 years (skeletally immature)
– Severe cardiac or pulmonary compromise
– Active systemic or local infection at treatment level
– Bleeding disorders
– Pregnancy
– Primary radicular pain or nerve root compression
– Previous lumbar surgery at intended treatment site (exceptions apply)
– Symptomatic spinal stenosis with neurogenic claudication
– Osteoporosis (T-score ≤ -2.5), fragility fractures, trauma, or malignancy at treated level
– Imaging findings of significant lumbar disc extrusion >5mm, spondylolisthesis >2mm, spondylolysis, or facet arthrosis correlated with pain
– BMI >40
– Advanced systemic disease limiting quality-of-life benefits without documented treatment objectives
– Untreated substance abuse disorder
Performing thermal destruction outside these criteria or more than once per vertebral body will likely result in denials.
ANESTHESIA AND IMAGING
Procedure typically performed with fluoroscopic imaging guidance and under moderate/conscious sedation or general anesthesia as medically appropriate.
FREQUENCY LIMITS
Single lifetime treatment per vertebral body (L3-S1). Multiple vertebrae may be treated in one session but repeat ablations on the same vertebra are noncovered.
