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.

Coverage stance

Covered when ALL of the following are met:

Primary coverage stance: For Commercial Products: dynamic posturography (CPT 92548) is considered not medically necessary because there are no studies demonstrating clinical utility that would lead to changes in management that improve outcomes; For Medicare Advantage Plans: dynamic posturography is considered not covered as the evidence is insufficient to determine the effects of the technology on health outcomes.

Statements reflect policy conclusions about insufficient evidence and lack of demonstrated clinical utility.

Provider Responsibilities and Billing Guidance

Prior Authorization

Prior Authorization / Benefits Verification

Prior authorization / benefits verification — Prior authorization is not applicable. Verify the member's Evidence of Coverage or Subscriber Agreement, as benefits and coverage may vary by contract.

Prior authorization: Not applicable
Action: Verify member eligibility and benefits via Evidence of Coverage / Subscriber Agreement

Note

Provider Action Note

Provider action: Follow payer participation agreement and billing guidance. If services are performed that are later determined to be non-covered or not medically necessary, the provider must have informed the member and obtained written agreement before billing the member directly.

Do not bill member for non-covered or not medically necessary services unless the member was notified and provided written agreement in advance
For member-specific benefit questions, contact the BCBSRI provider center

Documentation Required

Benefit Verification and Documentation

Benefit verification and documentation — Benefits and eligibility are determined by the member's subscriber agreement, member certificate, and/or employer agreement; those documents supersede this medical policy. Verify eligibility and applicable benefits before providing services.

Verify subscriber/employer agreements for coverage details
Document medical necessity in the medical record per payer requirements

Denial Risk

Denial Risk for CPT 92548

Denial risk — Computerized dynamic posturography (CPT 92548) is considered not covered for Medicare Advantage plans and not medically necessary for commercial products; claims for CPT 92548 may be denied.

Clinical Background

Dynamic posturography is a quantitative assessment of balance that measures a patient’s center-of-mass movement on a force platform while systematically altering visual and somatosensory inputs. The testing protocol includes multiple conditions (commonly six) that vary whether the eyes are open or closed and whether the support surface or visual surround is sway-referenced, with specific conditions (typically tests 5 and 6) designed to emphasize vestibular contributions to postural control.

The test is intended to isolate the relative contributions of vestibular, visual, and proprioceptive systems to balance in simulated everyday situations; however, there are no generally accepted reference standards and evidence is insufficient to show that results alter clinical management in ways that improve outcomes.

Key Definitions

Dynamic posturography tests (Computerized dynamic posturography)

DefinitionComputerized dynamic posturography (dynamic posturography) tests a patient’s balance control in situations intended to isolate factors that affect balance in everyday experiences and provides quantitative information on the degree of imbalance present.

Test methodThe patient, wearing a safety harness, stands on an enclosed force‑measuring platform surrounded by a visual field; the system alters platform angle and/or the visual surround while measuring center‑of‑mass movement to assess postural control.

Six test conditionsTesting consists of six situations that vary eyes open/closed, fixed vs sway‑referenced platform, and fixed vs sway‑referenced visual surround to evaluate visual, vestibular, and proprioceptive/somatosensory contributions to balance.

Sway‑referencing purposeSway‑referencing uses instantaneous computer‑controlled alterations of the platform or visual surround to cancel accurate somatosensory or visual feedback, isolating vestibular input (tests 5 and 6 primarily isolate vestibular cues).

Clinical limitationDynamic posturography provides functional information on balance but is not intended to diagnose specific balance disorder types or to localize the site of a lesion.
