Coverage Criteria

Not Medically Necessary / Unproven

Not medically necessary when ALL of the following apply:

Not covered (primary policy conclusion): Computerized dynamic posturography (CDP) testing is unproven and not medically necessary for evaluating any condition, including but not limited to balance or vestibular disorders, due to insufficient evidence of efficacy and lack of well-designed trials demonstrating diagnostic utility or improvement in patient-relevant outcomes.

Policy conclusion based on overall weak evidence in the peer-reviewed literature and insufficient demonstration of clinical utility; claims for CDP may be denied on that basis.

This Medical Policy does not apply to the states listed in the Application section. Refer to the state-specific policy or guideline where indicated for Idaho, Indiana, Kansas, Kentucky, Louisiana, Nebraska, New Jersey, New Mexico, North Carolina, Ohio, Pennsylvania, and Tennessee.

Specifically, the policy was revised to clarify that it does not apply to Nebraska and North Carolina; refer to the state-specific policy versions for those states. Earlier revisions also added Idaho and Kansas to the list of states with separate policy guidance.

Computerized dynamic posturography (CDP) testing is considered unproven and not medically necessary for evaluating any condition, including but not limited to balance and vestibular disorders, because of insufficient evidence of efficacy.

Coding

Applicable CPT CodesCPT

92548	Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions (i.e., eyes open, eyes closed, visual sway, platform sway, eyes closed platform sway, platform and visual sway), including interpretation and report.
92549	Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions (i.e., eyes open, eyes closed, visual sway, platform sway, eyes closed platform sway, platform and visual sway), including interpretation and report; with motor control test (MCT) and adaptation test (ADT)

Provider Actions & Billing

Prior Authorization

Prior Authorization May Be Required

Prior authorization: Providers should verify whether prior authorization is required by the member's plan for CPT codes 92548 and 92549. UnitedHealthcare may use third‑party tools (for example, InterQual®) and plan- or state-specific rules may affect prior authorization requirements. Always check the applicable federal, state, or contractual benefit terms before submitting authorization requests.

Affected CPT codes: 92548, 92549

Denial Risk

CDP Testing Considered Unproven / Not Medically Necessary

Denial risk: Computerized dynamic posturography (CDP) testing (CPT 92548, 92549) is considered unproven and not medically necessary for evaluation of balance or vestibular disorders due to insufficient evidence of clinical benefit. Claims for CDP procedures may be subject to denial when the service is billed as diagnostic testing for these indications.

CPT 92548 — CDP sensory organization test, including interpretation and report

Background

Computerized dynamic posturography (CDP) is a platform-based assessment that evaluates a patient’s balance by manipulating sensory inputs. The test uses a moving or force platform to alter visual, proprioceptive, and vestibular information so that postural control can be assessed under varying conditions.

Definitions

inv-15: Computerized dynamic posturography (CDP) — platform-based test definition and alternate names

Alternate namesMoving platform posturography; dynamic posturography; balance board testing; equilibrium platform testing (EPT)

PurposeUsed to attempt to isolate vestibular causes of imbalance by assessing postural responses under varying sensory conditions.

inv-16: 92548 / 92549 — CPT code definitions for sensory organization test and motor control/adaptation tests

92548Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions (eyes open; eyes closed; visual sway; platform sway; eyes closed platform sway; platform and visual sway), including interpretation and report.

92549Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions, including interpretation and report; with motor control test (MCT) and adaptation test (ADT).

Documentation Required

Documentation & Billing

Documentation and billing: If CDP testing is performed, include full documentation of the clinical indication, prior authorization (if obtained), and the interpretation/report required by CPT 92548 and 92549. Providers must follow the governing benefit plan's coverage terms; in case of conflict, federal, state, or contractual requirements govern.

Include interpretation and report with claim for CPT 92548 and 92549
Follow member's federal/state/contractual benefit terms when determining coverage

Note

Provider Responsibilities

Provider action: Check the member’s benefit plan and any applicable state or federal mandates prior to ordering CDP testing. Use available utilization management tools and follow any prior authorization procedures required by UnitedHealthcare or delegated entities.

Verify plan-specific prior authorization and medical necessity rules
Confirm whether third‑party criteria (e.g., InterQual®) apply

Listing of a code in this policy is for reference and does not imply coverage; benefit coverage is determined by federal, state, or contractual requirements.

inv-17: Computerized dynamic posturography — concise definition as objective assessment of postural control used in vestibular contexts

Concise definitionAn objective assessment of postural control using a platform whose stability is manipulated to evaluate how vision, proprioception, and vestibular inputs contribute to balance.

Clinical contextEmployed in vestibular and balance evaluation to measure ability to maintain balance under varying sensory conditions and to help localize vestibular dysfunction.

Limitations notedEvidence of clinical utility is limited; studies are generally small and do not clearly demonstrate improved patient-relevant outcomes.
