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 determinations

Covered when product-specific coverage criteria are met:

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

Commercial Products: Dynamic posturography is considered not medically necessary for commercial products because the evidence is insufficient to determine the effects of the technology on health outcomes.

This policy addresses coverage for computerized dynamic posturography (CDP). For Medicare Advantage plans, dynamic posturography is not covered because the evidence is insufficient to determine effects on health outcomes. For Commercial products, dynamic posturography (CPT 92548, 92549) is considered not medically necessary for the same reason: insufficient evidence demonstrating impact on health outcomes.

For Commercial products, CDP procedures (CPT 92548 and 92549) are considered not medically necessary. The cited rationale is that the available evidence is insufficient to determine the effects of this technology on health outcomes, and therefore does not support medical necessity for these services.

Note

Verify Member Benefits

Verify member-specific benefits, eligibility, and contract limitations prior to providing services. Benefits and coverage may vary between groups and contracts; refer to the member's Evidence of Coverage or Subscriber Agreement for applicable coverage determinations.

Check eligibility and benefit limits with the member's plan
Confirm whether services are covered under the member's contract

Denial Risk

Denial Risk for Computerized Dynamic Posturography

Claims for CPT codes 92548 and 92549 are not covered for Medicare Advantage plans and are considered not medically necessary for commercial products under this policy. Submissions using these codes risk denial.

92548 — Computerized dynamic posturography
92549 — Computerized dynamic posturography sensory organization test (CDP-SOT); 6 conditions, including interpretation and report; with motor control test (MCT) and adaptation test (ADT)

Clinical background

Computerized dynamic posturography (CDP) is a diagnostic testing method that evaluates a patient’s functional balance control by altering platform and visual surround conditions across standardized test conditions (sensory organization testing) and measuring center-of-mass or sway responses. Commonly reported components include the 6-condition sensory organization test and adjunctive motor control and adaptation testing. Although CDP characterizes vestibular, visual, and somatosensory contributions to postural control, the evidence base is limited; current findings have not demonstrated that CDP use leads to management changes that improve health outcomes, which is the basis for the coverage determinations above.

Key definitions

Computerized dynamic posturography (CDP) — definition and test description

TermComputerized dynamic posturography (CDP)

DefinitionA testing method in which a patient wearing a safety harness stands on an instrumented (force) platform within an enclosed visual surround; platform angle and visual surround are altered across six conditions to isolate visual, somatosensory/proprioceptive, and vestibular contributions to postural control and to measure center-of-mass movement.

Test componentsTypically consists of six testing conditions (Sensory Organization Test) varying eyes open/closed, platform fixed or sway-referenced, and visual surround fixed or sway-referenced; may include motor control and adaptation tests.

Sway-referencing — technique used in CDP testing

TermSway-referencing

Use in testingApplied in select CDP conditions to remove reliable somatosensory/visual cues so that the test isolates vestibular contributions to balance (eg, in tests 4–6 where the support surface is sway-referenced).

Clinical effectBy canceling accurate feedback from somatosensory or visual systems, sway-referencing helps evaluate how patients rely on vestibular input for postural control.
