TL;DR: UnitedHealthcare modified its computerized dynamic posturography coverage policy for Medicare Advantage, effective October 1, 2025. If your team bills CPT 92548 or 92549, here's what changes.
UnitedHealthcare updated its Medicare Advantage medical policy for computerized dynamic posturography (CDP), effective October 1, 2025. This change ties coverage for CPT 92548 and CPT 92549 directly to Local Coverage Determinations (LCDs) issued by Medicare Administrative Contractors — meaning your reimbursement now depends heavily on which MAC jurisdiction your patients fall under. The UHC computerized-dynamic-posturography policy now draws a hard line: if there's an LCD in your state or territory, that LCD governs. If there isn't, UnitedHealthcare falls back to its commercial medical policy.

UnitedHealthcare Computerized Dynamic Posturography Coverage Criteria and Medical Necessity Requirements 2025
The core of the UHC computerized dynamic posturography coverage policy is this: there is no CMS National Coverage Determination (NCD) for CDP. CMS never issued one. That means coverage has always been regional — and UnitedHealthcare is now making that framework explicit in its Medicare Advantage policy.
Where a Local Coverage Determination exists, that LCD controls. Your billing team must look up the specific LCD issued by the Medicare Administrative Contractor for your jurisdiction and treat it as the binding medical necessity standard. Compliance with applicable LCDs is required, not optional.
Where no LCD exists, UnitedHealthcare applies its commercial medical policy for computerized dynamic posturography as the fallback coverage policy. That's a meaningful distinction — commercial policy criteria may differ from LCD criteria, and mixing them up is a fast path to a claim denial.
CDP itself evaluates a patient's ability to maintain balance when the sensory systems that normally keep a person upright — vision, proprioception, and vestibular function — are systematically manipulated. The test runs six conditions in the sensory organization test (CDP-SOT) format. The clinical goal is isolating vestibular symptoms to a specific, treatable cause. Standard complementary diagnostics include electronystagmography and rotational chair tests.
From a medical necessity standpoint, CDP is positioned as a tool for patients where the standard workup hasn't pinpointed the source of balance dysfunction. If your documentation doesn't show why the standard tests were insufficient or why CDP adds clinical value beyond what electronystagmography already provided, expect scrutiny. Medical necessity documentation needs to tie directly to the LCD criteria in your jurisdiction — not to a general clinical description of balance disorders.
Prior authorization requirements for CPT 92548 and 92549 under UnitedHealthcare Medicare Advantage plans may vary by plan and market. Check prior authorization requirements for your specific plan contracts before October 1, 2025. Don't assume that because CDP wasn't requiring prior auth before this modification, it won't require it under the updated policy framework.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| CDP sensory organization testing in states/territories with an active LCD | Covered (when LCD criteria met) | 92548, 92549 | Must meet the specific LCD medical necessity criteria for your MAC jurisdiction |
| CDP sensory organization testing in states/territories with no LCD | Covered (when commercial policy criteria met) | 92548, 92549 | UHC commercial medical policy for CDP applies as fallback coverage policy |
| CDP testing that does not meet applicable LCD or commercial policy criteria | Not Covered | 92548, 92549 | Claim denial likely if documentation fails to satisfy the governing policy standard |
UnitedHealthcare Computerized Dynamic Posturography Billing Guidelines and Action Items 2025
The real issue here is that this policy change shifts the compliance burden onto your billing team to know which policy framework applies — before you submit a claim. That's not a passive requirement. Here's what to do.
| # | Action Item |
|---|---|
| 1 | Map your MAC jurisdiction before October 1, 2025. Identify which Medicare Administrative Contractor covers each state or territory where you bill. Then pull the specific LCDs for computerized dynamic posturography from those MACs. The applicable LCD — not a general CDP policy — is now the controlling standard for UnitedHealthcare Medicare Advantage claims. |
| 2 | Audit your CPT 92548 and 92549 documentation templates against the applicable LCD. Each LCD has its own medical necessity criteria, diagnosis code requirements, and documentation language. Generic documentation that says "balance disorder" won't hold up. Tie every claim to the specific clinical criteria the LCD requires. |
| 3 | Identify your no-LCD states and pull the UHC commercial policy. If you bill in states or territories without an active LCD, the UnitedHealthcare commercial medical policy for CDP governs. Get a copy of that policy, read the medical necessity criteria, and update your documentation accordingly. The billing guidelines differ between the LCD and commercial policy tracks. |
| 4 | Verify prior authorization requirements by plan and market. Contact UnitedHealthcare provider services or check your specific plan contracts to confirm whether prior auth is required for CPT 92548 or 92549 under your Medicare Advantage plan agreements. Do this before the effective date of October 1, 2025. |
| 5 | Train your coders on the two-track coverage framework. Your coders need to know at claim submission whether they're working under an LCD or the commercial policy fallback. Build that check into your charge capture workflow for CPT 92548 and CPT 92549. A misfiled claim under the wrong framework is a preventable denial. |
| 6 | Review any claims for CDP billed before October 1, 2025. If you have open or pending claims for CPT 92548 or 92549, verify they were billed under the correct prior policy standards. This policy modification may affect how UHC reviews claims on audit. |
If your practice spans multiple states with different MAC jurisdictions, this policy is more complicated than it looks on the surface. Talk to your compliance officer before the effective date to map out which LCDs apply where — and make sure your billing team isn't applying a single documentation standard across jurisdictions that require different ones.

CPT, HCPCS, and ICD-10 Codes for Computerized Dynamic Posturography Under computerized-dynamic-posturography
Covered CPT Codes (When Medical Necessity and LCD or Commercial Policy Criteria Are Met)
| Code | Type | Description |
|---|---|---|
| 92548 | CPT | Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions (eyes open/closed, fixed/sway-referenced surface and visual surround) |
| 92549 | CPT | Computerized dynamic posturography sensory organization test (CDP-SOT), 6 conditions (eyes open/closed, fixed/sway-referenced surface and visual surround), with motor control test and adaptation test |
Both CPT 92548 and CPT 92549 are covered when the applicable LCD or UHC commercial policy medical necessity criteria are met. The difference between the two codes matters: 92549 includes the motor control test and adaptation test components in addition to the sensory organization test. Document which components you actually performed. Upcoding to 92549 when only the SOT was performed is an audit risk.
There are no HCPCS Level II codes listed under this policy, and no ICD-10-CM codes are specified in the UHC computerized-dynamic-posturography policy document. Your ICD-10 code selection should be driven by the diagnosis requirements in the applicable LCD or commercial policy — not by this policy alone.
