Coverage Summary

This is a UnitedHealthcare Pennsylvania-only medical policy (Policy Number CS023PA.Q, effective April 1, 2026) that addresses coverage for Computerized Dynamic Posturography (CDP). The scope is limited to services delivered in Pennsylvania; requests that do not meet Pennsylvania Access, Referral and Prior Authorization Program (PARP) criteria will be evaluated case-by-case per Pennsylvania Code, Title 55, Chapter 1101.

The policy's coverage stance is not_covered_cosmetic — CDP testing is considered unproven and not medically necessary for evaluating any condition, including but not limited to balance disorders. The high-level rationale is that peer-reviewed evidence is weak and insufficient to demonstrate diagnostic utility or consistent patient-centered benefit; the Clinical Evidence section and recent supporting-information update reflect these findings.

Medical Necessity / Coverage Rationale

Coverage Rationale / Medical Necessity

CDP testing is considered unproven and not medically necessary for evaluating any condition including but not limited to balance disorders due to insufficient evidence of efficacy.

ALL of the following

Computerized dynamic posturography testing (CDP) is unproven and not medically necessary for evaluating any condition, including but not limited to balance disorders, due to insufficient evidence of efficacy.
This policy applies only to the state of Pennsylvania; any requests for services that do not meet criteria set in the Pennsylvania Access, Referral and Prior Authorization Program (PARP) will be evaluated case-by-case per Pennsylvania Code, Title 55, Chapter 1101.

Not Medically Necessary / Experimental

Policy stance: Computerized dynamic posturography testing (CDP) is considered unproven and not medically necessary for evaluating any condition in Pennsylvania due to insufficient evidence of efficacy.

Providers should expect that claims for CDP performed in Pennsylvania are generally subject to denial consistent with this policy. Per the Application section, requests that do not meet PARP criteria may be reviewed on a case-by-case basis under Pennsylvania Code, Title 55, Chapter 1101, with supporting documentation for state-specific exceptions.

See provider actions and applicable codes for procedural coding and denial risk (policy effective 04/01/2026; updates reflect supporting information changes).

Documentation Required

State-specific exceptions evaluation

For Pennsylvania, providers may have requests evaluated on a case-by-case basis per the Pennsylvania Access, Referral and Prior Authorization Program (PARP). Supporting documentation consistent with state exceptions should be submitted per Pennsylvania Code, Title 55, Chapter 1101.

Note: PARP and Pennsylvania Code, Title 55, Chapter 1101 apply

Background & Evidence Summary

Computerized dynamic posturography (CDP), also called moving platform or dynamic posturography, uses a platform device that manipulates vision, proprioception, and vestibular inputs to evaluate an individual's ability to maintain balance under varying sensory conditions. The goal of testing is to help isolate vestibular causes of balance problems.

Standard diagnostic vestibular tests referenced in the policy include electronystagmography and rotational chair tests, which evaluate eye movements in response to head position and rotation; the policy states there is a lack of well-designed trials showing CDP's diagnostic utility compared with these standard tests and insufficient evidence of consistent, beneficial effects on patient-relevant outcomes.

Study / Source	Summary
David & Shahnaz RCT (2024)
Small single-center randomized controlled trial (n=37) comparing clinic-based computerized vestibular retraining therapy (CVRT) with a home exercise program (HEP). CVRT improved Sensory Organization Test (SOT) composite and dynamic equilibrium scores versus HEP (SOT composite change 14.3 vs no change; p=0.04), but no between-group differences in some patient-reported outcomes and the study was limited by small size and methodological issues.
Hayes Evolving Evidence Review (2021, updated 2023)
Systematic review/technology assessment found no studies meeting inclusion criteria for clinical validity or utility of CDP for diagnosing vestibular disorders; identified weak guideline support based on expert opinion rather than robust clinical studies.
AAO-HNS position (2014)
AAO-HNS position statement recognized computerized static and dynamic platform posturography (including moving/dynamic platform posturography) as medically indicated and appropriate in the evaluation of persons with suspected balance or dizziness disorders (informational guideline statement).

Computerized Dynamic Posturography (CDP): Also known as moving platform posturography or dynamic posturography; a platform device that evaluates an individual's ability to maintain balance under varying sensory conditions by manipulating vision, proprioception, and vestibular input.

Sensory Organization Test (SOT): A component of CDP assessing balance across six sensory conditions and producing composite and equilibrium scores.
