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 Determination and Rationale

General coverage determination

Covered when ALL of the following are met

Policy coverage stance: Computerized dynamic posturography testing is considered unproven and not medically necessary for evaluating any condition due to insufficient evidence of efficacy

This is a blanket non-coverage stance based on weak and insufficient evidence described in the clinical evidence section.

Computerized dynamic posturography (CDP) testing is not medically necessary and is explicitly excluded from coverage for evaluating any condition, including but not limited to balance disorders, because the peer-reviewed evidence is insufficient to demonstrate clinical efficacy.

FDA clearance, device registration, or a 510(k) listing alone does not establish that a device or procedure is covered. FDA product codes relevant to vestibular testing include LXV, IKN, and KHX, and some device categories (LXV and KHX) are Class I, 510(k)-exempt; this regulatory status is informational and is not a basis for medical coverage.

Rationale: The policy finds CDP testing to be unproven and not medically necessary for the evaluation of any condition because available studies provide insufficient evidence of benefit. As a result, use of CDP for diagnostic assessment of balance or vestibular disorders is not supported for coverage decisions.

Prior Authorization

Check prior authorization and member plan verification

Check the member-specific benefit plan document and any applicable federal or state mandates before scheduling services. In the event of a conflict, the member-specific benefit plan governs. Verify prior authorization requirements with the plan prior to performing services.

Clinical Background and Technology

Background: Computerized dynamic posturography (CDP) is a platform-based test that assesses an individual’s ability to maintain balance by manipulating visual, proprioceptive, and vestibular inputs. The test uses a moving platform and sensory conditions to isolate contributing systems to postural control and quantify functional balance performance.

Denial Risk

Not medically necessary rationale

Computerized dynamic posturography testing (CDP), including CPT 92548 and 92549 (with or without motor control test/adaptation test), is considered unproven and not medically necessary for evaluating balance disorders due to insufficient evidence of efficacy. Claims may be denied on a 'not medically necessary' basis when billed for evaluation of balance or related conditions.

Not medically necessary — operational denial guidance: deny when CDP is billed for evaluation of balance disorders due to insufficient evidence
Affected CPT codes: 92548, 92549 (with or without MCT/ADT)

Billing Rule

Coding reference

The following codes are referenced for billing and claims review. Inclusion here is for reference and does not guarantee coverage — confirm via the member-specific benefit plan.

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

Documentation Required

Verify member-specific benefits

Before relying on this policy, confirm member eligibility, benefits, and any prior authorization or coverage mandates. When conflicts exist between this Medical Policy and the member-specific benefit plan document, the member-specific plan governs.
