Prior authorization required; document smoking cessation for fusion

Prior authorization is required and must include the documentation items listed in the policy (see "Required documentation"); for elective cervical, lumbar, or thoracic fusion, document preoperative smoking cessation of at least 4 weeks and willingness to refrain from smoking for 3 months post-op (testing may be requested at Medical Director discretion).

• Smoking cessation ≥4 weeks pre-op; may be waived for severe/progressive neurologic deficits
• Laboratory testing for smoking cessation compliance may be required at Medical Director discretion

Submit required documentation items with prior authorization

Include all items listed under the policy's Documentation Requirements when submitting prior authorization: indication for surgery; surgeon evaluation within prior 6 months; detailed neurological exam within 3 months; documentation of conservative care and response; functional impairment assessment; management of cognitive/behavioral/addiction issues when present; and radiologist reports for imaging performed within the past 12 months (read by an independent radiologist).

• Indication for requested surgery
• Surgeon evaluation within previous 6 months
• Neurological exam performed/reviewed by operating surgeon within 3 months
• Clinical documentation of conservative care and response (PT, medications, procedures)
• Radiologist report(s) for diagnostic imaging within past 12 months (independent read)

Evidence sections summarize literature; follow documented prior authorization rules

The clinical evidence sections in the document summarize literature and do not themselves define prior authorization rules; where only evidence summaries are presented, follow the policy's explicit prior authorization and documentation sections for operational requirements.

Prior authorization: document failed conservative care and selection rationale for discectomy/decompression

For discectomy/decompression requests, prior authorization documentation should demonstrate failure of conservative therapy (for radiculopathy typically ~6 weeks) and include indication, surgeon exam, neurological findings correlating with imaging, and rationale for technique selection (open, micro, or endoscopic) based on comparative evidence and surgeon expertise.

• Document failed conservative care duration (e.g., ~6 weeks for lumbar radiculopathy)
• Provide surgeon exam and neurological findings that correlate with imaging
• Explain rationale for choosing discectomy technique and surgeon expertise

Prior authorization suggested for annular closure devices (Barricaid) with defect documentation

Adjunct annular closure devices (e.g., Barricaid) should be submitted with prior authorization and documentation supporting the indication (e.g., large annular defect 6–10 mm) because studies show reduced reherniation and reoperation in select populations but have limitations. Include device name and indication details.

• Document annular defect width (e.g., 6–10 mm subgroup)
• Include device name and trial or study identifiers when applicable
• Provide rationale linking device use to evidence in patients with large annular defects

Prior authorization recommended for BMAC-related fusion with preparation/rationale

Requests involving bone marrow aspirate concentrate (BMAC) for spinal fusion should be prior authorized with submission of supporting evidence and procedural details, because ECRI reviews found evidence inconclusive compared with iliac crest bone graft (ICBG). Include preparation method and comparator graft material in documentation.

• State rationale for BMAC use and comparator graft (e.g., ICBG)
• Describe BMAC preparation and application method
• Attach relevant evidence or trial identifiers if available

Prior authorization recommended for uncommon or higher‑risk procedures (AxiaLIF, annulus repair)

Complex or less-common procedures (e.g., AxiaLIF, annulus repair implants) should be submitted for prior authorization to ensure appropriate selection and informed consent; supply evidence, risk discussion, and device details given limited evidence and reported complication signals.

• Provide device/procedure name and published evidence
• Document discussion of risks and informed consent
• Include justification for selecting the approach over standard techniques

Billing & coding: add-on/bundling rules and unrecognized HCPCS S2348

Follow the policy's billing rules when submitting claims: certain codes are add-on or bundled (e.g., CPT 22585 is add-on and only billable with 22554/22556/22558; CPT 22841 is not separately payable), and HCPCS S2348 is not recognized — use valid CPT/HCPCS or an appropriate unlisted code with prior authorization to avoid denial. Unlisted codes are reviewed at claim level.

• 22585 is an add-on code; bill only with 22554/22556/22558
• 22841 is not separately payable per Company Coding Policy
• HCPCS S2348 is not a valid code; use alternate CPT/HCPCS or unlisted code (reviewed)

Obtain prior authorization for unlisted codes to avoid post‑service denial

When no specific CPT/HCPCS code exists, obtain prior authorization for an unlisted code to avoid post-service denial; unlisted codes will be reviewed for medical necessity, correct coding, and pricing at the claim level. If an unlisted code is submitted for a non‑covered service addressed in this policy, it will be denied.

• Prior authorization recommended for potentially covered services billed with an unlisted code
• Unlisted codes for non‑covered services will be denied as not covered
• All unlisted codes are reviewed for medical necessity and pricing

Prior authorization may be affected by Q1 2026 code and criteria updates

Be aware that the policy underwent a Q1 2026 code set update and interim NMN additions; code and criteria changes may affect prior authorization expectations — verify current code lists and criteria when submitting requests.

• Q1 2026 code set update noted in revision history
• Interim updates added not‑medically‑necessary criteria and codes in 1/2025 and 6/2025

Conservative therapy generally required before surgery

The policy requires failed conservative treatment before most surgical interventions; for cervical indications exceptions exist for intolerable pain or progressive neurologic changes, and thoracic/lumbar criteria generally require ≥3 months of conservative care unless exceptions apply.

• Conservative care must generally have failed prior to surgery
• Thoracic/lumbar: symptoms failed to improve after 3 months of conservative treatment (unless exceptions)

Conservative care must be recent and include PT participation

Conservative care must be recent (within the past year) and include participation in physical therapy (at least 3 visits unless a prior course was completed), oral analgesics/anti‑inflammatories (or pain program), and oral corticosteroids when appropriate; exceptions allowed for specified severe or progressive neurologic findings. Document participation and response.

• Conservative care must be within the last year
• At least 3 physical therapy visits during conservative management unless prior PT documented

No separate step‑therapy program specified in these excerpts

The excerpts do not specify formal step therapy programs or mandatory step edits beyond the conservative care requirements; follow the policy's conservative‑care expectations rather than an external step‑therapy protocol.

Document ~6 weeks failed conservative care before discectomy for radiculopathy

For lumbar radiculopathy, systematic reviews and the Washington State findings support recommending surgery (open discectomy or microdiscectomy) after failed approximately 6 weeks of conservative care; prior authorization should document this failure duration.

• Typical failed conservative care duration cited ~6 weeks for lumbar radiculopathy prior to discectomy
• Evidence supports open discectomy or microdiscectomy after failed 6 weeks conservative care

Expect conservative therapy requirement before device‑based decompression (MILD)

When requesting device‑based decompression procedures (e.g., MILD), expect payers to require documentation of prior conservative treatment because evidence is low‑quality and comparative trials use epidural steroid injections as comparators; include prior conservative therapy details in authorization.

• MILD evidence rated 'C' by Hayes; RCT compared mild to epidural steroid injections
• Document prior conservative treatments (e.g., ESIs, PT) when requesting device procedures

Reserve fusion for facet syndrome to research or after conservative care

For suspected facet syndrome, lumbar fusion is no longer commonly supported outside prospective clinical research; consider conservative management or enrollment in research before fusion and document research participation if applicable.

• Lumbar fusion for facet syndrome should generally be limited to prospective clinical research
• Document conservative management attempts and rationale for research enrollment

Document conservative care and standard surgical comparators when selecting novel techniques

When comparing novel or endoscopic techniques, document how conservative management and standard surgical options were considered and why the selected approach is appropriate, since established surgical options (open discectomy) are referenced as standard comparators in evidence and guidelines.

• Explain why endoscopic or novel technique was chosen over standard discectomy
• Provide evidence or surgeon expertise supporting the selected technique

Procedures with limited evidence may require extra justification or be NMN

Procedures and devices lacking supportive evidence (e.g., percutaneous/endoscopic decompression procedures, axial lumbar interbody fusions, annular closure devices in some indications, and BMAC) are listed as limited or not supported by evidence and may require additional justification or will be considered not medically necessary.

• Percutaneous/endoscopic decompression procedures and AxiaLIF cited as lacking supportive evidence
• BMAC evidence deemed inconclusive by ECRI

Required documentation to support medical necessity review

Submit the full set of required documents for medical necessity review: indication for surgery; surgeon evaluation within prior 6 months; detailed neurological exam performed or reviewed within 3 months by the operating surgeon; documentation of conservative care and its outcomes; assessment of functional impairments; management of cognitive/behavioral/addiction issues when present; and radiologist reports for diagnostic imaging completed within the past 12 months (independent read).

• Indication for the requested surgery
• Surgeon evaluation within previous 6 months
• Neurological exam within 3 months performed/reviewed by operating surgeon
• Radiologist reports for MR/CT within 12 months (independent read)

Timeframes: surgeon exam, neurologic exam, and imaging recency required

For medical necessity review, ensure surgeon evaluation is within 6 months and a detailed neurological examination has been performed or reviewed within 3 months; include clinical documentation of conservative care and response, and independent radiologist imaging reports performed within the past 12 months.

• Surgeon evaluation ≤6 months prior to request
• Neurologic exam ≤3 months prior to surgery
• Imaging studies and radiologist report ≤12 months

Evidence summaries do not add documentation requirements

The evidence‑only sections do not specify additional documentation requirements; rely on the policy's Documentation Requirements section for operational submission expectations.

Document failure of conservative care before discectomy and justify technique

Evidence reviews recommend open discectomy or microdiscectomy (with or without endoscopy) for lumbar radiculopathy after failed conservative care; as a provider action, document failure of conservative therapy and selection of discectomy technique consistent with evidence.

• Document failure of conservative care (~6 weeks) for lumbar radiculopathy
• Provide rationale for selecting open, micro, or endoscopic discectomy

Provide clinical trial and device details with authorization requests

When the procedure is performed in the context of a clinical trial or involves a device, include trial identifiers, procedure type, device name (e.g., mild®, Barricaid), indication details (e.g., large annular defect 6–10 mm), and any governance/consent/audit arrangements required by NICE or ISASS guidance.

• Include clinical trial ID and study role if applicable
• Provide device name and indication details (e.g., annular defect size)
• Attach evidence and governance/consent/audit documentation when required

Document smoking status/counseling and BMAC preparation details

Clinical documentation should explicitly record patient smoking status and counseling; for BMAC use, document the rationale, BMAC preparation method, and the comparator graft material because ECRI found evidence inconclusive and reviewers may request these details.

• Record smoking status and documentation of counseling/cessation plan
• For BMAC, describe preparation method and comparator graft material (e.g., ICBG)
• Attach supporting evidence for expected benefit when available

Document governance/consent/audit and defect rationale for annular repair devices

When annular repair devices are used, provide documentation that supports special arrangements (governance, consent, audit) per NICE or ISASS recommendations and include device rationale tied to a large annular defect if applicable.

• Document governance/consent/audit arrangements if device use follows NICE guidance
• Include evidence that patient fits device‑study population (e.g., large annular defect)

Use valid CPT/HCPCS codes; S2348 not recognized

Use valid CPT/HCPCS codes for claim submission; HCPCS S2348 is not recognized and providers must use alternate CPT/HCPCS codes or an appropriate unlisted code (which will be reviewed). Incorrect or unrecognized codes may result in claim denial.

• HCPCS S2348 is not a valid claim code; use alternate CPT/HCPCS or unlisted code
• Unlisted codes are reviewed for medical necessity and pricing at claim level

Unlisted codes reviewed for medical necessity; prior auth recommended

All unlisted codes submitted will be reviewed for medical necessity, correct coding, and pricing at the claim level; to avoid post‑service denial for potentially covered services billed with an unlisted code, prior authorization is recommended. Unlisted codes tied to non‑covered services will be denied.

• Unlisted codes are reviewed for medical necessity, coding, and pricing
• Prior authorization recommended for potentially covered services billed with unlisted codes
• Unlisted codes for non‑covered services will be denied

Attach supporting evidence references to authorization requests

Extensive references are provided in the policy to support indications, device use, and comparative effectiveness; include relevant citations when submitting evidence to support authorization or medical necessity determinations.

• Policy includes systematic reviews, RCTs, and guideline citations to support decisions
• Attach relevant references to authorization requests when available

Missing smoking cessation or required documentation may result in denial

Failure to document preoperative smoking cessation when required, or omission of required documentation (indication, recent surgeon exam, neurologic exam, conservative care, imaging) may lead to denial of the medical necessity determination.

• Missing smoking cessation documentation may affect medical necessity for fusion
• Omitted surgeon exam (≤6 months), neurologic exam (≤3 months), or imaging (≤12 months) may trigger denial

Incomplete documentation (missing required items/timeframes) may trigger denial

Failure to submit required documentation—such as the indication for surgery, surgeon evaluation within 6 months, neurological exam within 3 months, documentation of conservative care and functional impairment, and radiologist imaging reports within 12 months—may result in denial of the request. Provide all listed items to reduce denial risk.

• Indication for surgery
• Surgeon evaluation within prior 6 months
• Neurologic exam within 3 months
• Radiologist reports for imaging within 12 months

Evidence summaries do not specify authorization/denial triggers

The evidence‑focused excerpts do not state explicit authorization triggers; operational prior authorization and denial risks are defined in the policy's Documentation and Prior Authorization sections.

Minimally invasive procedures without laminectomy/laminotomy are not covered and risk denial

Minimally invasive procedures that do not include laminectomy, laminotomy, or foraminotomy (including automated percutaneous discectomy, percutaneous laser, nucleoplasty, and certain energy‑ablation techniques) are not covered per the Washington State review and may be denied if requested. Provide strong justification or avoid requesting coverage for these techniques.

• Automated percutaneous discectomy, percutaneous laser, nucleoplasty listed as not covered by Washington State review
• Minimally invasive procedures without laminectomy/laminotomy/foraminotomy are non‑covered

Low‑quality evidence procedures (e.g., MILD) carry denial/additional‑review risk

Procedures supported only by low‑quality evidence (for example, MILD rated 'C' by Hayes) may face additional review or denial due to insufficient comparative effectiveness data; include robust supporting documentation when requesting these services.

• MILD evidence assessed as 'C' (potential but unproven benefit) by Hayes
• Provide stronger evidence or justification to mitigate denial risk

High‑risk evidence profiles (e.g., AxiaLIF) may prompt additional review or denial

Devices or procedures with high risk of bias, limited comparative data, or elevated complication/revision rates (e.g., AxiaLIF) may trigger additional review or denial; include complication risk discussion and supporting evidence if submitting for authorization.

• AxiaLIF reports high reported fusion rates but noted variable complication/revision rates and high risk of bias
• Document risk‑benefit justification and alternatives when requesting these procedures

BMAC evidence limitations may lead to additional review or denial without supporting evidence

ECRI concluded that BMAC evidence for cervical and lumbar fusion is inconclusive; use of BMAC may prompt additional review or non‑coverage decisions unless adequate comparative evidence and rationale are provided. Document BMAC rationale and comparative evidence when requesting coverage.

• ECRI found BMAC evidence inconclusive compared with ICBG
• Provide RCTs or comparative evidence when available to support BMAC use

Document smoking status, counseling, and cessation plan to mitigate risk

Document patient smoking status and counseling because smoking is associated with higher rates of pseudarthrosis, infection, delayed fusion, and worse outcomes; failure to document cessation counseling may affect medical necessity for fusion.

• Smoking increases pseudarthrosis and infection risk
• Document counseling and cessation plan, and laboratory testing if requested

Procedures strongly recommended against (percutaneous laser) may be denied

Procedures with strong recommendations against use (e.g., percutaneous laser disc decompression per HERC) are likely to be denied; do not submit authorization requests for such procedures without compelling, study‑level justification.

• HERC issued a strong recommendation against percutaneous laser disc decompression for low back pain
• Requests for strongly discouraged procedures may be denied

Unlisted codes for non‑covered services will be denied

Unlisted codes submitted for non‑covered services addressed in this policy will be denied as not covered; ensure coding aligns with covered services and obtain prior authorization for unlisted codes tied to potentially covered services.

• Unlisted codes for non‑covered services will be denied
• Prior authorization recommended for unlisted codes for potentially covered services

Unlisted codes reviewed at claim level; risk of post‑service denial without prior auth

Unlisted codes are reviewed for medical necessity and correct pricing at the claim level; if an unlisted code is submitted without prior authorization for a potentially covered service, the claim may be denied post‑service. Seek prior authorization when unsure.

Percutaneous/endoscopic procedures reclassified as not medically necessary; denial likely

Percutaneous and endoscopic procedures were reclassified to 'not medically necessary' in the 4/2023 revision; such procedures may be denied when billed under that determination. Check current policy NMN lists before submitting requests.

• 4/2023 revision changed classification of percutaneous/endoscopic procedures to 'not medically necessary'
• Interim updates in 1/2025 and 6/2025 added NMN criteria and codes
