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.

Coverage Criteria

Not medically necessary / Unproven

Not medically necessary/unproven when used to visualize spinal movement

Primary stance: Digital motion x-ray and cineradiography/videofluoroscopy used to visualize movement of the back or spine are considered unproven and not medically necessary due to insufficient evidence of efficacy.

The literature is limited to small studies and low-quality cohorts; larger controlled trials are needed to demonstrate impact on clinical care and superiority to alternatives.

Vertebral motion analysis stance: Vertebral motion analysis is considered unproven and not medically necessary due to insufficient evidence that reductions in measurement variability improve diagnostic accuracy or health outcomes.

Studies report reduced variability versus flexion/extension radiographs, but the evidence is insufficient to determine effect on clinical outcomes.

This policy does not apply to certain states that have their own state-specific policy or guideline for Diagnostic Dynamic Spinal Visualization and Vertebral Motion Analysis. Refer to the listed state policies where applicable. States with separate policies include Idaho, Indiana, Kansas, Kentucky, Nebraska, New Jersey, New Mexico, North Carolina, Ohio, Pennsylvania, and Tennessee. (See the individual state policy/guideline for coverage determination and requirements.)

The following modalities are explicitly described in this policy as unproven and not medically necessary when used to visualize spinal movement: digital motion x-ray of the spine, cineradiography/videofluoroscopy, and vertebral motion analysis. These techniques lack sufficient evidence of efficacy to support their use for assessment of spine movement.

Dynamic spinal visualization and vertebral motion analysis for assessment of spinal movement

The following dynamic spinal visualization techniques and vertebral motion analysis are not supported as medically necessary for assessment of spinal movement.

Indication guidance: No indications for digital motion x-ray, cineradiography/videofluoroscopy, or vertebral motion analysis are supported as medically necessary in this policy; these techniques are considered unproven for evaluation and assessment of spine movement due to insufficient evidence.

ECRI and systematic reviews found insufficient high-quality evidence and existing studies are small or of low quality.

Provider Actions & Billing

Prior Authorization

Prior Authorization and Code Note

Prior authorization requirements depend on the member’s specific plan and any applicable federal, state or contractual rules. Verify prior authorization with the member’s plan administrator before scheduling services.

Affected codes: 0693T, 76120, 76125
Prior authorization: governed by member’s benefit plan and applicable laws

Denial Risk

Denial Risk for Dynamic Spinal Visualization

Requests for dynamic spinal visualization techniques (including digital motion x-ray, cineradiography/videofluoroscopy, and vertebral motion analysis) are routinely subject to denial because these procedures are considered unproven and not medically necessary due to insufficient evidence of efficacy.

Denial risk applies to: digital motion x‑ray of the spine; cineradiography/videofluoroscopy; vertebral motion analysis systems

Definitions

Digital motion x-ray

DefinitionDigital motion x-ray: sequential x-ray 'snapshots' (film or computer-based) captured as a person moves; digitized images are ordered and played as a moving image for physician review or computerized analysis.

Modality detailsSnapshots may be digitized from film or created directly in digital format; computer software assembles images into a motion sequence for evaluation.

Primary useVisualize vertebral and external body movement to assess presence or absence of structural abnormalities during motion.

Cineradiography/videoradiography (videofluoroscopy)

DefinitionCineradiography/videoradiography (videofluoroscopy): fluoroscopy-based procedure that creates real-time video (motion pictures) of internal body structures for display and analysis.

Function

Background

Dynamic spinal visualization methods produce moving images of the spine during motion using different technologies. Digital motion x-ray acquires sequential digitized x‑ray images to visualize motion. Cineradiography/videofluoroscopy uses fluoroscopic real‑time video to image internal structures during movement. Vertebral motion analysis systems combine assisted bending with fluoroscopic imaging and computerized or automated tracking to quantify intervertebral motion. The available evidence consists mainly of small studies and diagnostic cohorts; while some studies report reduced measurement variability versus standard flexion/extension radiographs, the evidence is insufficient to demonstrate improved diagnostic accuracy or better clinical outcomes.

Not Covered

Digital motion x‑ray, cineradiography/videofluoroscopy, and vertebral motion analysis for visualization or diagnostic assessment of spinal movement are considered not covered / not medically necessary by this policy due to insufficient evidence of efficacy and uncertain impact on clinical outcomes. Requests for these procedures are therefore subject to denial as unproven.

Prior Authorization

Follow member’s plan-level prior authorization requirements for all modalities

For all listed modalities, verify and follow the member’s plan-level prior authorization requirements; federal, state, or contractual terms take precedence over this policy.

Confirm prior authorization rules with the member’s benefit plan before ordering services.
In case of conflict, follow federal, state, or contractual coverage requirements rather than this policy.
