Computerized Dynamic Posturography

This UnitedHealthcare medical policy defines the applicability and coverage rationale for computerized dynamic posturography (CDP) testing across commercial plans (with state exceptions listed). It states the policy position that CDP is unproven and not medically necessary for evaluating any condition and provides associated CPT codes, clinical evidence summary, FDA/device info, and revision history.

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.

This policy is effective April 1, 2026. Computerized dynamic posturography (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, and therefore is not covered under this policy. This policy applies to UnitedHealthcare commercial plans with state exceptions; the policy does not apply to the states listed (see state-specific policies where noted).

Medical-Necessity Criteria

Medically Necessary / Not Medically Necessary

Coverage decision for computerized dynamic posturography:

Computerized dynamic posturography testing is unproven and not medically necessary for evaluating any condition, including but not limited to balance disorders, due to insufficient evidence of efficacy.

Provider Actions

Prior Authorization

Prior authorization / coverage determination required by contract

Review federal, state, and contractual benefit plan requirements prior to providing or billing for computerized dynamic posturography (CDP). Contractual or applicable law requirements may differ from this standard policy and govern in the event of a conflict; check prior authorization/coverage determination rules as required by the applicable plan.

Documentation Required

Reference supporting documentation and evidentiary basis

Retain clinical documentation that demonstrates medical necessity for CDP. Note that the policy states CDP is considered unproven and not medically necessary for evaluating any condition due to insufficient evidence; claims may be denied on that basis if documentation does not support medically necessary use under the applicable benefit plan.

Billing Rule

Codes provided for reference only

The CPT codes listed for CDP are provided for reference only and their presence in this policy does not imply that the service is covered or reimbursable. Benefit coverage and reimbursement are determined by federal, state, or contractual requirements and other policies; inclusion of a code is informational and does not guarantee payment.

Background & Evidence

Computerized dynamic posturography (CDP) uses a moving platform to assess an individual’s ability to maintain balance by manipulating vision, proprioception, and vestibular cues. CDP has been used both diagnostically and as part of rehabilitation protocols (for example, computerized vestibular retraining), but standard vestibular diagnostics typically include tests such as electronystagmography and rotational chair testing. The peer-reviewed evidence regarding CDP’s diagnostic utility and its impact on patient-relevant outcomes is weak, with a lack of well-designed trials demonstrating that CDP provides consistent, clinically meaningful benefits compared with standard testing.

Clinical evidence summaries

Overall evidence strengthWeak; insufficient well-designed trials demonstrating diagnostic utility or consistent beneficial effects on patient-relevant outcomes.

Randomized trial (David & Shahnaz 2024)Small RCT (n=37) showed some SOT improvements with clinic-based CVRT vs home exercise but limited by small size, crossover/withdrawal and other methodological issues.

Systematic review / Hayes reviewHayes Evolving Evidence Review (2021, updated 2023) found no studies meeting inclusion criteria and weak guideline support based on expert opinion.

Computerized dynamic posturography (CDP): Platform-based testing that evaluates an individual's ability to maintain balance under varying sensory conditions by manipulating vision, proprioception, and vestibular inputs.

Sensory Organization Test (SOT): A component of CDP assessing balance across six conditions that manipulate vision and platform stability, with composite scores used to quantify balance function.
