CMS Updates Coverage Policy for Ultrasonic Surgery in Meniere's Syndrome Treatment (NCD 5)
CMS has issued a modification to National Coverage Determination (NCD) 5, which governs Medicare reimbursement for ultrasonic surgery—a specialized procedure used to treat severe, recurrent vertigo caused by Meniere's syndrome. This update affects otolaryngologists, neurotologists, and the billing teams supporting them. Understanding what the policy covers, and how to document claims correctly, is essential before the March 12, 2026 effective date.

What CMS NCD 5 Covers: Ultrasonic Surgery for Meniere's Syndrome
The Centers for Medicare & Medicaid Services (CMS) allows reimbursement for ultrasonic surgery when it is medically necessary for patients experiencing severe and recurrent episodes of vertigo due to Meniere's syndrome. This is not a broad authorization—coverage is tied specifically to that diagnosis and symptom profile.
Meniere's syndrome is a disorder of the inner ear characterized by episodic vertigo, hearing loss, tinnitus, and ear fullness. For patients with severe, recurrent vertigo that has not responded to conservative management, ultrasonic surgery offers a targeted intervention. The procedure uses high-intensity, high-frequency ultrasonic waves to selectively irradiate and destroy specific tissue within the inner ear responsible for triggering vertigo episodes.
Billing teams should recognize that "recurrent" and "severe" are the operative words in the medical necessity standard here. A single episode of vertigo or a mild presentation is not sufficient to establish coverage. Your clinical documentation needs to reflect a pattern of episodes and the degree of functional impairment before this service will hold up on audit.
How the Ultrasonic Surgery Procedure Works—and Why It Matters for Billing
Understanding the clinical procedure is directly relevant to claims accuracy. CMS's policy describes the procedure in specific terms that should map to your operative notes and supporting documentation.
The procedure is typically performed under local anesthesia and requires two individuals: a surgeon who performs the intervention, and a second individual responsible for calibrating the electrical equipment and observing physical responses in the patient—specifically nystagmus (involuntary eye movement) that indicates inner ear reaction to the ultrasonic destruction. Both roles are called out explicitly in the policy.
This two-person requirement has real billing implications. Claims that reflect only the primary surgeon without documentation of the second person's role may invite scrutiny. Make sure your operative reports clearly describe the presence and function of the equipment operator/assistant.
CMS also notes that the desired result is typically achieved in a single treatment. Repeat procedures should be supported by documentation explaining why the initial treatment was insufficient—because payers will flag multiple claims for the same patient without that clinical rationale.
Two Approved Surgical Approaches Under NCD 5
The policy explicitly recognizes two technical approaches for applying ultrasound to the inner ear:
- Through the lateral semicircular canal — the longer-established technique
- Through the round window — described as a more technically straightforward approach introduced more recently
Both approaches are covered under the policy. However, the approach used should be documented in the operative note, as it may affect how the procedure is coded and what supporting documentation your clinical team needs to provide.
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
Affected Codes
This policy does not list specific CPT, HCPCS, or ICD-10 codes. NCD 5 contains no code table in the current version of the policy document.
For billing purposes, your coding team will need to identify the appropriate CPT code for ultrasonic surgery of the inner ear based on the specific approach used (lateral semicircular canal vs. round window) in coordination with your coding resources and payer guidelines. Work with a certified otolaryngology coder or consult the AMA's CPT codebook to ensure the correct procedure code is applied.
Because no codes are enumerated in the NCD, claims are evaluated on the basis of the narrative medical necessity criteria described above—making thorough documentation even more critical.
Medical Necessity Criteria: What CMS Requires for Coverage
Based on NCD 5, a Medicare claim for ultrasonic surgery should be supported by documentation that demonstrates all of the following:
| # | Covered Indication |
|---|---|
| 1 | The patient has a confirmed diagnosis of Meniere's syndrome (not generic vertigo or another vestibular disorder) |
| 2 | The vertigo episodes are severe—meaning they significantly impair function or daily activity |
| 3 | The episodes are recurrent—a documented pattern over time, not an isolated incident |
| 4 | The procedure is being performed as a treatment, not for diagnostic or experimental purposes |
| 5 | The procedure involved a surgeon and a calibration/observation assistant as described in the policy |
| 6 | The appropriate surgical approach (lateral semicircular canal or round window) is documented |
There are no prior authorization requirements explicitly stated in this NCD. However, that does not mean your MAC (Medicare Administrative Contractor) won't impose local coverage requirements. Check with your applicable MAC before assuming prior auth is off the table.
What Your Billing Team Should Do
| # | Action Item |
|---|---|
| 1 | Audit your current documentation templates for ultrasonic surgery procedures before March 12, 2026. Confirm that operative note templates capture the two-person team requirement, the surgical approach used, and the patient's symptom history—specifically the severity and recurrence of vertigo. |
| 2 | Confirm CPT code selection with a certified coder experienced in otolaryngology. Because NCD 5 does not enumerate specific codes, you need to be confident the procedure code you're submitting accurately reflects the approach used and aligns with your MAC's local coding guidance. |
| 3 | Check with your MAC for any Local Coverage Determinations (LCDs) that may layer additional requirements on top of NCD 5. MACs like Noridian, Novitas, or CGS may have issued LCDs or articles that specify codes, documentation standards, or prior authorization requirements specific to your jurisdiction. |
| 4 | Flag repeat procedure claims for additional documentation review before submission. The policy notes that one treatment typically achieves the desired result—claims for subsequent procedures on the same patient need a clear clinical explanation in the record. |
| 5 | Update your denial management workflows to include NCD 5 as a reference document for any ultrasonic surgery denials. If CMS denies a claim for this service, the appeal should directly address the medical necessity language in the NCD and demonstrate how the patient's clinical presentation meets each criterion. |
