Coflex device: Medically necessary and not medically necessary criteria added for Coflex; redundant policy statements removed.

Operational and coding clarifications made.

CPT edits: E/I indication removed from CPT codes 22867 and 22868.

Indicates coding/indication change for those codes.

Presence of unmanaged significant mental or behavioral health disorders (for example, major depressive disorder, chronic pain syndrome, secondary pain, or substance use disorders such as opioid or alcohol use disorders) may preclude coverage. Approval for lumbar decompression procedures requires documentation demonstrating the absence of unmanaged significant mental or behavioral health disorders prior to authorization.

Epidural steroid injections or selective nerve root blocks performed at the same level(s) as the requested surgery are recognized as part of the conservative-treatment pathway and may be used to document a trial of nonoperative care. However, discography or MR spectroscopy results will not be used as determinative evidence of medical necessity.

Use of an FDA‑approved interlaminar decompression device (e.g., Coflex) is only considered medically appropriate when used as part of an open lumbar decompression and not when the open decompression is performed together with a lumbar fusion.

An FDA‑approved interlaminar decompression device (e.g., Coflex) is not medically necessary in several scenarios, including when the device is used without meeting the applicable decompression criteria, in the presence of Meyerding Grade 2 or higher degenerative spondylolisthesis, when spondylolysis or isthmic spondylolisthesis is present, when a lumbar fusion is performed at the same level, or when decompression is not performed as an open procedure.

Discography and MR spectroscopy results will not be used as determining factors of medical necessity for requested lumbar decompression procedures and are not endorsed as standalone evidence in prior authorization documentation.

Percutaneous image‑guided minimally invasive decompression (mild) devices are contraindicated for use near lateral neural elements and are contraindicated for disc procedures. These devices are intended to resect ligamentum flavum and small laminar bone under fluoroscopic guidance and are not appropriate when lateral neural element access or disc work is required.

Interspinous devices are not indicated for several conditions, including degenerative spondylolisthesis of Grade 2 or higher, degenerative scoliosis or coronal instability, dynamic instability (flexion-extension translation ≥ 3 mm), iatrogenic instability, or when other FDA contraindications apply (for example, prior fusion or decompressive laminectomy at the index level, osteoporosis, morbid obesity, active infection, or pain of unknown etiology).

Services described in this policy are contract dependent. Medical policy criteria apply only when the product covers a specific service; if a product does not cover a service, the medical policy criteria do not apply and coverage decisions must defer to the product's benefit design.

Requests for lumbar decompression without advanced imaging (MRI or CT) showing neural structure compression at the requested level(s) that is concordant with the individual's symptoms and physical examination will be denied. Imaging must identify compression caused by pathologies such as herniated disc (including retained or recurrent fragments), synovial/arachnoid cyst, central/lateral/foraminal stenosis, or osteophytes to meet the radiologic concordance requirement.

Lumbar decompression performed solely to address annular tears, concordant discography findings, MR spectroscopy results, or degenerative disc disease without concordant imaging and clinical indications is considered not medically necessary and will not meet coverage criteria.

Stabilization and distraction implants, including interspinous process spacer devices and interspinous stabilization/distraction systems (for example, Superion), are considered investigational when used following decompression or as stand‑alone procedures and are therefore not covered under the policy's medically necessary indications.

Long‑term safety and efficacy remain uncertain for many interspinous and interlaminar devices. Meta-analyses and systematic reviews have shown comparable short‑term symptom outcomes for some devices versus decompression surgery but have reported higher reoperation rates and variable long‑term evidence, indicating unresolved questions about durability and appropriate patient selection.

Devices and implants that are investigational or not FDA‑approved (including HCPCS C1821 when designated E/I) are considered experimental/investigational and are typically not medically necessary for coverage. Prior authorization and coding must reflect device regulatory status and applicable policy exclusions.

For Medicare and Medicare HMO‑DSNP products, if the product covers a service and there is no national or local Medicare coverage determination, this medical policy's criteria apply. If a Medicare HMO‑DSNP product does not cover a specific service, refer to the Medicaid product coverage line for guidance.

Requests lacking MRI/CT evidence of neural structure compression concordant with the individual's symptoms and physical exam at the requested level(s) will be denied. Imaging concordance with clinical findings is a fundamental requirement for elective lumbar decompression procedures.

Prior Authorization, Documentation, and Provider Requirements

Prior Authorization

Prior authorization — document ALL clinical criteria and concordant imaging

Prior authorization must document that ALL listed clinical criteria and concordant MRI/CT imaging are met before elective primary lumbar decompression for neurogenic claudication (i.e., significant daily pain with functional impairment; pain provoked by walking/positions and improved with sitting/forward flexion; failure of required conservative therapies; and MRI/CT showing neural structure compression concordant with symptoms and exam).

Subjective symptoms and symptom pattern documented
Evidence of failed conservative therapies documented
MRI/CT report showing neural compression concordant with symptoms and exam

Prior Authorization

Prior authorization — failed conservative care required (≥2 modalities, ~6 weeks each)

Prior authorization must include documentation of failed conservative care: at least two conservative treatments (e.g., provider-directed exercise program and prescription-strength medications), each typically for six (6) weeks unless contraindicated.

Background and Evidence Context

Neurogenic claudication from lumbar spinal stenosis or spondylolisthesis typically presents as leg pain, weakness, or paresthesia provoked by walking or spinal extension and often relieved by sitting or forward flexion. Surgical lumbar decompression is intended to relieve neural element compression when conservative care has failed and imaging is concordant with symptoms.

inv-21: Imaging concordance — not medically necessary without concordant MRI/CT

Imaging concordance requirement: Procedures without MRI/CT evidence of neural structure compression concordant with symptoms or not caused by the listed pathologies (herniated disc, synovial/arachnoid cyst, central/lateral/foraminal stenosis, osteophytes) are considered not medically necessary.

Imaging must be concordant with clinical presentation.

Evidence for many interspinous and interlaminar devices shows short‑term symptomatic improvements in select trials, but systematic reviews and longer‑term studies reveal higher reoperation rates and inconsistent long‑term benefit. Guidelines (for example, NASS) and device labeling highlight specific indications and contraindications; due to limitations in the long‑term comparative evidence base, the policy emphasizes cautious, criteria‑based use and the need for further high‑quality long‑term studies.

Definitions and Key Terms

Anatomic causes of compression

Herniated discHerniated disc (including retained or recurrent disc herniation) causing neural compression

Spinal stenosis typesCentral, lateral, or foraminal stenosis as causes of neural element compression

Osteophytes and cystsOsteophytes and synovial/arachnoid cysts identified on imaging as compression causes

Behavioral health requirement

RequirementAbsence of unmanaged significant mental or behavioral health disorders (e.g., major depressive disorder, chronic pain syndrome, opioid and alcohol use disorders)

Effect on coveragePresence of unmanaged disorders may preclude coverage until managed

Note

Product and contract dependency — verify product coverage

Services are contract dependent; verify the member's product covers the requested service — if not covered by the product, medical policy criteria do not apply.

Confirm product coverage before applying policy criteria
Follow product-specific coverage lines (Medicaid/Medicare exceptions)

Denial Risk

Denial risk — radiologic concordance missing

Lack of MRI/CT evidence showing neural structure compression concordant with symptoms at the requested level(s) is a common denial trigger.

Ensure imaging demonstrates neural compression concordant with symptoms and exam
Absence of concordant imaging may lead to denial

Denial Risk

Denial risk — inadequate conservative therapy documentation

Requests may be denied if documentation does not show at least two conservative therapies (e.g., 6‑week PT and 6‑week pharmacologic trial) unless clearly contraindicated.

Document two distinct conservative therapies with dates/durations
Provide rationale if therapies were contraindicated

Denial Risk

Denial risk — imaging lacks listed pathologic cause of compression

Procedures may be denied if imaging does not show neural structure compression caused by a listed pathology (herniated disc, synovial/arachnoid cyst, central/lateral/foraminal stenosis, osteophytes).

Imaging must specify the cause of compression at requested level(s)
Lack of listed pathologic cause on imaging may trigger denial

Denial Risk

Denial risk — behavioral health exclusion if unmanaged

Coverage may be precluded when unmanaged significant mental or behavioral health disorders are present (e.g., major depressive disorder, chronic pain syndrome, opioid or alcohol use disorders) until those conditions are managed.

Document absence of unmanaged significant behavioral health disorders
If present, include treatment/management plan

Denial Risk

Denial risk — not indicated scenarios and investigational devices

Procedures may be denied if performed solely for annular tears, concordant discography, MR spectroscopy results, or degenerative disc disease; stabilization/distraction implants and many interspinous devices are investigational and may be denied.

Do not base medical necessity solely on annular tears or discography/MR spectroscopy
Investigational interspinous/spacer devices may be denied

Denial Risk

Denial risk — incomplete prior authorization documentation

Incomplete prior authorization requests lacking required CPT codes, disc levels/motion segments, ICD-10 codes, detailed nonsurgical treatment history and responses, or independent radiologist imaging reports risk denial.

Include CPT codes, planned operative levels, and ICD-10 codes
Provide independent radiologist report and reconcile discrepant interpretations
Detail nonsurgical treatment history with responses

Denial Risk

Denial risk — lack of urgent/emergent documentation

Absence of documentation supporting an urgent/emergent indication (when claimed) — such as epidural hematoma, infection, neoplastic compression, or incapacitating pain — may lead to denial if usual criteria are otherwise required.

Provide clear documentation of the urgent/emergent diagnosis and exams
State which usual prerequisites are being waived and why

Denial Risk

Denial risk — contraindications and not‑indicated scenarios for interspinous devices

Interspinous/interlaminar devices are not indicated and would be denied when NASS/FDA criteria are not met, including Grade 2+ spondylolisthesis, degenerative scoliosis, dynamic instability (≥3 mm translation), prior fusion at index level, or other FDA-listed contraindications.

Document spondylolisthesis grade and flexion‑extension instability
Confirm absence of FDA contraindications (osteoporosis, morbid obesity BMI>40, active infection, etc.)

Denial Risk

Denial risk — CMS coverage gap may affect Medicare authorizations

No specific National or Regional Medicare coverage decisions address lumbar decompression and interspinous process decompression devices; absence of CMS determinations may affect authorization for Medicare products.

Verify local Medicare/contract guidance for Medicare products
Be aware CMS has no specific coverage determination for these services

DocumentationBehavioral health status should be documented in prior authorization materials

Partial or complete corpectomy definition

DefinitionPartial or complete corpectomy: removal of at least one‑third of the vertebral body (not limited to resection of osteophytes)

IndicationsPerformed for infection, trauma, tumor, or compression at/behind the vertebral body level

Fusion implicationCorpectomy usually requires fusion when iatrogenic instability results

Meyerding Grade 1 degenerative spondylolisthesis

DefinitionMeyerding Grade 1 degenerative spondylolisthesis: low‑grade anterior displacement of a vertebral body

Policy allowancePermitted with interlaminar device use (e.g., Coflex) when other device criteria are met

LimitationsHigher grades (Grade 2+) are contraindicated for interspinous/interlaminar devices

Lumbar corpectomy — definition and fusion requirement

DefinitionLumbar corpectomy: surgical removal of one or more lumbar vertebral bodies (and adjacent discs)

Fusion requirementMust be performed with a lumbar fusion when the corpectomy causes iatrogenic instability

Common indicationsUsed for trauma, infection, tumor, or compression not amenable to less extensive decompression

Interspinous process decompression (IPD) systems/devices

DefinitionInterspinous process decompression (IPD) systems/devices: implantable devices placed between spinous processes intended to provide indirect decompression

ExamplesSuperion ISS, X-STOP, TOPS (Total Posterior Spine System)

PurposeEnlarge neural foramen and limit extension to relieve neurogenic intermittent claudication

Clinically meaningful improvement

Threshold for clinical improvementClinically meaningful improvement defined as a global assessment showing at least 50% improvement

Use in documentationPrior authorization must document less than clinically meaningful improvement (<50%) after nonsurgical treatments

Applied toAssessment of response to conservative therapies when considering surgery

Laminectomy / Laminotomy / Foraminotomy / Corpectomy definitions

LaminectomyRemoval of the entire bony lamina, part of enlarged facet joints, and thickened ligaments to decompress neural elements

LaminotomyRemoval of a small portion of the lamina and ligaments, usually unilateral, preserving laminar support

Foraminotomy/CorpectomyForaminotomy: removal of bone around the neural foramen; Corpectomy: removal of one or more vertebral bodies and adjacent discs

Interspinous/interlaminar implants (static vs dynamic)

Static implantsStatic interspinous devices (e.g., X-STOP, ExtenSure, Wallis) are noncompressible spacers maintaining constant distraction

Dynamic implantsDynamic interspinous/interlaminar devices (e.g., DIAM, Coflex) allow axial compression/expansion and may preserve motion

Device examplesStatic: X-STOP, ExtenSure, Wallis. Dynamic: DIAM, Coflex

Percutaneous image-guided minimally invasive decompression (mild) — definition

DefinitionPercutaneous image-guided minimally invasive decompression (mild): ultra-minimally invasive procedure using a cannula and single-use tools under fluoroscopic guidance to resect ligamentum flavum and small lamina pieces

ContraindicationsNot intended for use near lateral neural elements and contraindicated for disc procedures

Clinical criteriaASPN recommends use for symptomatic lumbar spinal stenosis with neurogenic claudication and ligamentum flavum hypertrophy >=2.5 mm

Neurogenic claudication definition

DefinitionNeurogenic claudication: symptomatic leg pain or weakness related to lumbar spinal canal narrowing, often relieved by flexion (sitting/forward flexion)

Typical provocationSymptoms provoked by walking or standing and alleviated by sitting/forward flexion

RelevanceConsidered when selecting decompression or percutaneous decompression therapies

FDA contraindications for interlaminar device use — listed

Contraindication list (FDA)Prior fusion or decompressive laminectomy at index level; radiographically compromised vertebral bodies from trauma/tumor; severe facet hypertrophy requiring extensive bone removal; Grade II or greater spondylolisthesis; isthmic spondylolisthesis or spondylolysis; degenerative lumbar scoliosis (Cobb >25°); osteoporosis; back/leg pain of unknown etiology; axial back pain only without leg/buttock/groin pain; morbid obesity (BMI>40); active/chronic infection; known allergy to titanium alloys or MR contrast agents; cauda equina syndrome causing neurogenic bowel/bladder dysfunction

ApplicationThese FD A-listed contraindications apply to interlaminar device (e.g., Coflex) use

DocumentationRadiographic assessment for these contraindications should be provided prior to authorization
