Coverage and Medical Necessity Determinations

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 stance

Policy coverage determinations by product:

Medicare Advantage: Dynamic posturography is not covered as the evidence is insufficient to determine the effects of the technology on health outcomes.

Commercial Products: Dynamic posturography is not medically necessary as the evidence is insufficient to determine the effects of the technology on health outcomes.

Provider Requirements, Prior Authorization, and Denial Risk

Prior Authorization

Prior authorization is not applicable for services described in this policy. However, benefit coverage can vary by contract; always check the member's Evidence of Coverage or Subscriber Agreement for prior authorization requirements specific to that plan.

Prior Authorization: Not applicable (per policy).
Verify Evidence of Coverage / Subscriber Agreement for contract-specific requirements.

Documentation Required

Member Benefits and Informed Consent

Verify member-specific benefits and eligibility before providing services. If performing testing, document that informed consent was obtained and note any member agreement when services are non-covered or not medically necessary.

Check member eligibility and benefits with the provider call center or member documents.
Obtain and document informed consent if performing testing that may be non-covered or not medically necessary.
Do not bill members for services determined to be non-covered unless the member was informed in advance and agreed in writing to self-pay.

Denial Risk

Denial Risk for Dynamic Posturography

Dynamic posturography (CPT 92548, 92549) is considered not covered / not medically necessary by Medicare Advantage and commercial products in this policy; claims may be denied.

Medicare Advantage: Dynamic posturography not covered (insufficient evidence).
Commercial products: Dynamic posturography considered not medically necessary (insufficient evidence).
Affected CPT codes: 92548, 92549 — claims may be denied.

Clinical Background

Dynamic posturography is a quantitative balance assessment performed with an instrumented force platform and visual surround to alter sensory inputs and measure sway and center-of-mass movement. Testing commonly includes a six-condition sensory organization test that varies visual input (present, absent, sway-referenced) and support surface (stable or sway-referenced) to evaluate visual, vestibular, and somatosensory contributions to postural control. Results characterize what sensory information a patient can or cannot use to maintain balance but do not localize the site of a lesion.

Terms and Test Description

Computerized dynamic posturography (CDP) — definition and key characteristics

DefinitionComputerized dynamic posturography (CDP) is a balance assessment using an instrumented force platform and an enclosed visual surround to alter visual and somatosensory inputs and quantify postural control.

Key instrumentsInstrumented platform (force platform) to calculate center-of-mass movement; enclosed visual surround for sway-referencing.

Sensory conditions / test componentsA standard sensory organization test includes six conditions varying vision (eyes open, eyes closed, sway-referenced) and support surface (fixed or sway-referenced) to evaluate visual, somatosensory/proprioceptive, and vestibular contributions.

Sway-referencingComputer-aided instantaneous alterations of the platform or visual surround to cancel accurate somatosensory or visual feedback and isolate other sensory inputs.

Patient safety and setupPatient stands wearing a harness to prevent falls while the platform and visual surround are manipulated.

What it measures / limitationsMeasures functional ability to maintain balance (center-of-mass movement) but cannot localize lesion site; no accepted reference standard and insufficient evidence demonstrating improved health outcomes.
