Coverage Summary

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.

Not Covered / Experimental

Coverage stance: Computerized dynamic posturography testing is designated as not covered / not medically necessary because it is considered unproven for evaluating any condition, including but not limited to balance disorders. The policy states that CDP testing lacks sufficient evidence of efficacy and is therefore not medically necessary for evaluation. Benefit coverage may vary and is determined by federal, state, or contractual requirements, which should be consulted as noted in the provider guidance.

Background and Evidence

Background: Computerized dynamic posturography (CDP) is a platform-based assessment that evaluates an individual’s ability to maintain balance by manipulating vision, proprioception, and vestibular inputs and includes tests such as the Sensory Organization Test (SOT), Motor Control Test (MCT), and Adaptation Test (ADT).

Evidence limitations: The peer-reviewed literature provides weak and limited evidence for CDP’s diagnostic utility and clinical benefit. There is a lack of well-designed trials demonstrating CDP’s superiority or consistent impact on patient-relevant outcomes compared with standard vestibular tests, and systematic reviews and evidence reviews have found insufficient data to support clinical utility.

Evidence	Summary
Randomized controlled trial (David & Shahnaz 2024)	Small single-center RCT (n=37) comparing rehabilitative CDP (CVRT) vs home exercise showed improvements in SOT composite and dynamic equilibrium with CVRT, but had small sample size and methodological limitations; participant-reported outcomes improved in both groups with no between-group differences for most measures.
Hayes Evolving Evidence Review (2021, updated 2023)	Review found no studies meeting inclusion criteria for diagnostic performance or utility; weak support based on expert opinion and insufficient evidence for clinical or diagnostic utility of CDP.
