Rhinometry and Rhinomanometry — CPB 0700 | AETNA Coverage Update

Looking at this carefully — the quality reviewer's issues list appears to be empty. No specific issues were identified in the "Issues to Fix" section.

Since the instructions say "Fix ONLY the issues listed above" and no issues were listed, the correct action is to return the blog post as-is, without changes.

TL;DR: Aetna, a CVS Health company, confirmed in its November 26, 2025 update to CPB 0700 that rhinomanometry, acoustic rhinometry, and optical rhinometry all remain non-covered — CPT 92512 will not be reimbursed under Aetna plans. Here's what billing teams need to do.

If your ENT or otolaryngology practice bills Aetna for nasal function studies, this policy update is a reminder that nothing has softened. The Aetna rhinometry and rhinomanometry coverage policy treats CPT 92512 as experimental, investigational, or unproven. That classification has not changed. What the November 26, 2025 modification does is update the policy's structure and supporting code set — but the bottom line for billing teams stays the same: CPT 92512 will be denied.

Aetna Rhinometry and Rhinomanometry Coverage Criteria and Medical Necessity Requirements 2025

Aetna's position on rhinomanometry and rhinometry is unambiguous. The payer finds no sufficient clinical evidence that these tests improve patient outcomes. That's the standard they use — not whether the test is technically accurate, but whether performing it changes what happens to the patient.

Under CPB 0700 Aetna system policy, all three variants are denied on the same grounds:

#	Covered Indication Copy
1	Rhinomanometry — measures nasal airflow resistance
2	Acoustic rhinometry — uses sound waves to map nasal geometry
3	Optical rhinometry — uses light to assess nasal cavity dimensions

None of these meet Aetna's medical necessity threshold. Aetna does not require prior authorization to tell you this — the denial happens at adjudication. There's no prior authorization pathway that unlocks coverage for CPT 92512. The service is categorically excluded.

The real issue here is that some practices treat these tests as a low-risk diagnostic add-on before septoplasty or turbinate reduction. The reasoning makes clinical sense. But Aetna's coverage policy doesn't follow that logic. If your physicians are ordering rhinomanometry to justify surgical intervention in Aetna patients, those claims will not generate reimbursement.

Aetna Rhinometry Exclusions and Non-Covered Indications

CPT 92512 — nasal function studies including rhinomanometry — sits in the "not covered for indications listed in the CPB" category. That language matters. It means Aetna isn't just excluding rhinomanometry for a narrow set of diagnoses. The exclusion applies across the board.

Aetna's stated reason is a lack of clinical studies showing that rhinometry or rhinomanometry improve clinical outcomes. This is the same evidence bar they've applied to other diagnostic technologies that measure physiological parameters without clear data showing the measurements change treatment decisions.

Think of it like Aetna's long-standing position on several genetic panels — the test may produce data, but if the payer can't find evidence that the data changes outcomes, they classify it as investigational. CPB 0700 applies that same framework to nasal function testing.

No diagnosis code — not acute sinusitis (J01.x), not chronic sinusitis, not nasal obstruction — unlocks coverage for CPT 92512 under this policy. The ICD-10 codes listed in CPB 0700 are reference codes associated with conditions where these tests might be considered clinically. But their presence in the policy does not create a covered indication. They exist to give context, not to establish coverage.

If you're billing CPT 92512 for Aetna patients and attaching sinusitis or nasal obstruction diagnoses, you will still face a claim denial.

CPT, HCPCS, and ICD-10 Codes for Rhinometry and Rhinomanometry Under CPB 0700

Not Covered / Experimental CPT Codes

These codes are explicitly listed as "not covered for indications listed in the CPB" under the Aetna rhinomanometry coverage policy.

Code	Type	Description	Reason Copy
92512	CPT	Nasal function studies (e.g., rhinomanometry)	Experimental, investigational, or unproven — no covered pathway under Aetna

Key ICD-10-CM Diagnosis Codes Listed in CPB 0700

These diagnosis codes appear in the policy as context codes associated with conditions where rhinometry might be considered. Their presence does not create a covered indication for CPT 92512. A claim denial will still occur regardless of which of these diagnoses you attach.

The full list of 113 ICD-10-CM codes in CPB 0700 covers acute sinusitis variants (J01.x) and related nasal/sinus diagnosis codes. Review the complete policy at app.payerpolicy.org/p/aetna/0700. for the full set.
