Coverage Determination

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Not medically necessary / Unproven

Covered when ALL of the following are met

Policy stance: Motorized spinal traction devices are considered unproven and not medically necessary for treating neck and low back disorders due to insufficient evidence of efficacy.

This policy states the service is not medically necessary; individual clinical coverage criteria are not provided in this portion of the document.

Clinical Evidence Summary (informational for coverage decisions)

Evidence summary relevant to coverage determinations

Evidence summary: Randomized trials and systematic reviews generally do not show superiority of motorized traction/non‑surgical spinal decompression (NSD) over sham or other active treatments; available positive findings are primarily from small case series, retrospective audits, or single trials with methodological limitations. Reported studies show short‑term pain and function improvements in some cohorts but are limited by small sizes, lack of controls, incomplete follow‑up, and potential bias.

See systematic reviews and RCTs (chunks 17–21) and major guideline assessments (chunks 23–24) concluding insufficient evidence.

Guideline conclusions: Major practice guidelines (American College of Physicians and North American Spine Society) state evidence is insufficient to determine the effectiveness of traction for acute, subacute, or chronic low back pain and do not recommend traction for subacute or chronic LBP or for lumbar disc herniation with radiculopathy.

Guideline statements summarized from ACP and NASS (chunks 23–24).

For neck pain, published clinical evidence for vertebral axial decompression and other motorized traction modalities is limited to case studies. Well-designed randomized controlled trials are lacking, and higher-quality comparative data are needed to determine whether these devices provide clinically meaningful benefit for cervical indications.

Major clinical practice guidelines concur that the evidence for traction is inadequate. The American College of Physicians (ACP) concludes that evidence is insufficient to determine the effectiveness of traction for acute, subacute, or chronic low back pain, and found no clear differences between traction and other active treatments. The North American Spine Society (NASS) likewise considers the evidence insufficient to recommend traction for subacute or chronic low back pain and for lumbar disc herniation with radiculopathy or lumbar spinal stenosis.

Provider Requirements and Billing Guidance

Prior Authorization

Prior Authorization Required

Requests for motorized spinal traction (HCPCS S9090) require prior authorization. Prior authorization determinations will follow InterQual criteria and UnitedHealthcare requirements, and must also comply with applicable Ohio rules and contractual provisions.

Prior authorization required for HCPCS S9090
Follow InterQual and UnitedHealthcare criteria
Ohio-specific rules apply

Prior Authorization

Prior Authorization via InterQual/UnitedHealthcare

Prior authorization reviews should use InterQual as the primary medical/surgical criteria set. If InterQual does not contain applicable criteria, reviewers may apply UnitedHealthcare Medical Policies, Coverage Determination Guidelines, and/or Utilization Review Guidelines that have been approved by the Ohio Department of Medicaid Services.

Use InterQual® primary criteria
If InterQual is not applicable, use UnitedHealthcare policies, Coverage Determination Guidelines, or Utilization Review Guidelines (ODMS-approved)

Note

State/Contract Compliance Required

This policy applies only in Ohio. Coverage determinations must reference and comply with federal law, the Ohio Administrative Code (OAC 5160-101), and any applicable contractual requirements. In the event of a conflict, federal, state (OAC) or contractual requirements govern.

State/contract compliance required: OAC 5160-101
Federal and contractual requirements supersede policy when conflicts occur

Documentation Required

Documentation and Coding Reference

Submit HCPCS code S9090 and supporting clinical documentation with all prior authorization requests. Include the diagnosis, detailed treatment history, prior conservative therapies tried, clinical findings, imaging results if applicable, and rationale for proposing motorized spinal traction.

Include HCPCS S9090 on request
Provide diagnosis, treatment history, prior conservative care, clinical findings, and imaging

Documentation Required

Required Documentation and Criteria References

Reviewers should consult InterQual, UnitedHealthcare Medical Policies, Coverage Determination Guidelines, and Utilization Review Guidelines when evaluating requests. Requests for therapies deemed unproven may be denied as not medically necessary.

Required references: InterQual, UnitedHealthcare Medical Policies, Coverage Determination Guidelines, Utilization Review Guidelines
Denial risk for unproven therapy (motorized spinal traction may be considered not medically necessary)

Note

Background and Scope

Vertebral axial decompression, a form of motorized spinal traction, uses a computer-driven table and a pelvic harness to apply controlled, cyclic distraction forces aimed at unloading intervertebral discs. The modality is intended to produce mechanical decompression of the spinal column, but available clinical evidence is limited, heterogeneous, and of low quality, yielding inconsistent clinical outcomes.

Definitions

Vertebral axial decompression (motorized spinal traction)

DefinitionA spinal traction modality using a computer-driven table and pelvic harness to apply controlled distraction cycles to the spine to attempt disc decompression.

Intended mechanismApplies cyclic distraction forces via a harness while the table extends and relaxes tension to unload intervertebral discs and reduce disc pressure and related pain.

Typical patient setupPatient lies on a specialized table with a pelvic harness; the table is slowly extended and cyclic tension/distraction forces are applied.

Treatment deliverySeries of cycles during a session where desired tension is reached and then gradually decreased; number and frequency of sessions vary by protocol.

Primary clinical aimAttempt to decompress discs to relieve neck or low back pain and improve function by reducing intradiscal pressure.

Non-surgical spinal decompression (NSD) / motorized traction — examples & brief definition

DefinitionMotorized traction therapies that apply controlled mechanical distraction forces to the spine aiming to reduce disc pressure and pain; evidence includes case series, retrospective audits, and randomized trials.

Examples / devicesDRX9000, IDD (Intervertebral Differential Dynamics), VAX-D.

Typical applicationAdministered as a course of repeated sessions (protocols vary by device), often delivered with the patient prone or supine on a motorized table using harnesses to apply distraction.

Evidence noteClinical studies range from case series and retrospective reports (e.g., DRX9000, VAX-D) to limited RCTs; well-designed randomized trials are needed to determine efficacy, especially for neck pain where evidence is limited to case studies.
