Coverage Criteria for Computerized Dynamic Posturography (CDP)

Not Medically Necessary (All Conditions)

Not covered — CDP is considered unproven and not medically necessary

Primary stance: Computerized dynamic posturography testing is unproven and not medically necessary for evaluating any condition due to insufficient evidence of efficacy and lack of well-designed trials demonstrating diagnostic utility or consistent beneficial effects on patient-relevant outcomes.

Computerized dynamic posturography (CDP), also referred to as balance board testing or equilibrium platform testing, is unproven and not medically necessary for evaluating any condition, including but not limited to balance disorders. The evidence is insufficient to support CDP as a diagnostic or evaluative test for vestibular or other disorders, and therefore CDP testing is not covered under this policy.

The coverage rationale is based on the available clinical evidence, which is weak and does not demonstrate that CDP provides diagnostic utility beyond standard vestibular tests. There is a lack of well‑designed trials showing that CDP improves patient‑relevant outcomes or consistently influences management decisions. Because studies do not show consistent beneficial effects, CDP is considered not medically necessary.

This Medical Policy is provided for informational purposes to assist interpretation of UnitedHealthcare standard benefit plans and does not constitute medical advice. Always apply the federal, state, or contractual benefit plan terms, which govern in the event of any conflict with this policy. Before relying on this policy, verify applicable plan requirements and prior authorization rules for the member’s benefit plan.

Provider Actions and Billing Guidance

Prior Authorization

Verify Prior Authorization Requirements

Verify Prior Authorization Requirements: Before ordering or performing computerized dynamic posturography (CDP) testing, check the member’s federal, state, and contractual benefit plan requirements for any prior authorization or other pre-service requirements. Plan-level rules may require prior authorization even when a service is listed in this policy.

Check federal, state, and contractual benefit plan requirements prior to service.
Prior authorization may be required by the member’s plan even if this policy identifies the service as not medically necessary.

Denial Risk

Denial Risk for CDP Testing

Denial Risk for CDP Testing: Computerized dynamic posturography (CDP) testing (CPT 92548, 92549) is considered unproven and not medically necessary for evaluation of balance or vestibular disorders. Claims for these services may be denied or reduced as not medically necessary under UnitedHealthcare standard benefit plans.

TermCDP / Computerized dynamic posturography

Alternate namesmoving platform posturography; dynamic posturography; balance board testing; equilibrium platform testing

Core descriptionUses a platform device that manipulates vision, proprioception, and vestibular inputs to evaluate an individual’s ability to maintain balance under varying sensory conditions.

Common test componentsSensory Organization Test (SOT) typically 6 conditions; may include Motor Control Test (MCT) and Adaptation Test (ADT).

PurposeTo isolate causes of vestibular or balance impairment by evaluating postural responses to altered sensory input.

inv-16: Posturography / Computerized Dynamic Posturography (CDP) — objective testing method definition

Background

Computerized dynamic posturography (CDP) is an objective testing method that evaluates postural control and balance using a movable platform to manipulate sensory inputs. CDP commonly measures a patient’s ability to maintain balance under varying sensory conditions by altering visual, proprioceptive, and vestibular cues, frequently performed as the Sensory Organization Test (SOT) and optionally including the Motor Control Test (MCT) and Adaptation Test (ADT). The test is intended to isolate contributors to imbalance by systematically changing platform stability and sensory conditions.

Reference Plan Terms and Conflict with Plan Terms

Reference Plan Terms / Conflict with Plan Terms: This Medical Policy provides guidance for UnitedHealthcare standard benefit plans but is not the sole determinant of coverage. Federal, state, or contractual benefit plan terms govern and may differ from this policy. In the event of any conflict, the federal, state, or contractual requirements for benefit plan coverage prevail.

Always reference the member’s specific plan/federal/state contractual terms when making coverage determinations.
If plan terms conflict with this policy, the plan/federal/state contractual requirements govern.

DefinitionPosturography / Computerized Dynamic Posturography (CDP) is an objective testing method to evaluate postural control and balance using a movable platform that varies stability and sensory conditions to assess sensory organization and postural responses.

Measured functionsAbility to maintain balance; interaction of vision, proprioception, and vestibular function; postural sway and compensatory responses.

Typical protocolSensory Organization Test (SOT) with six conditions (eyes open, eyes closed, visual sway, platform sway, eyes closed platform sway, platform and visual sway); may include interpretation and report.

Billing descriptorsCPT 92548: CDP-SOT, 6 conditions, including interpretation and report; CPT 92549: CDP-SOT, 6 conditions, including interpretation and report; with MCT and ADT.
