Medical necessity guidelines for surgical and procedural repair of nasal valve compromise for members of Health Net/Centene-affiliated health plans, including which procedures are considered medically necessary versus not medically necessary.
No material clinical or coverage changes in this revision.
Coverage Criteria for Repair of Nasal Valve Compromise
Medically Necessary Criteria
Repair of nasal valve compromise is medically necessary when ALL of the following are met:
Clinical findings should be supported by physical examination.
General policy applicability
Policy scope and application statements:
Coverage decisions are subject to all terms, conditions, exclusions and limitations of the enrollee's coverage documents and to applicable law and plan administrative policies.
This clinical policy states that certain procedures for repair of nasal valve compromise are not medically necessary because safety and efficacy have not been established. Specifically, the policy identifies radiofrequency ablation (VivAer®), absorbable nasal implants (Latera®), and nasal valve suspension surgery as procedures considered not medically necessary for repairing nasal valve compromise. These exclusions are listed in Section II of the policy and reflect the plan’s assessment of currently available evidence regarding those technologies.
For Medicaid members/enrollees, when state Medicaid coverage provisions conflict with the coverage provisions in this clinical policy, state Medicaid coverage provisions take precedence. Providers should consult the applicable state Medicaid manual for any coverage provisions that apply to this policy.
The following procedures are explicitly listed as not medically necessary for the repair of nasal valve compromise: VivAer® (radiofrequency ablation), absorbable nasal implants (Latera®), and nasal valve suspension surgery. The policy cites insufficient established safety and efficacy to support coverage of these specific interventions.
This document is intended to provide guidance used to evaluate medical necessity and to assist in making coverage decisions, but it does not itself create the legal or contractual definition of medical necessity. Providers are expected to exercise professional medical judgment and to consult enrollee coverage documents and applicable state or federal requirements when applying this guidance.

Provider Actions, Authorization, and Documentation Requirements
Prior Authorization / Code Implications
Prior authorization is required for procedures represented by CPT 30465. Coverage is contingent on documentation that all required clinical criteria (Section I.A–I.D) are met. Verify applicable CPT coding guidance prior to claim submission.
Prior Authorization and Coverage Alignment
Providers must review applicable National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) prior to applying this policy. Prior authorization requirements and coverage decisions remain subject to the member's contract terms, exclusions, and limitations.
- Prior authorization applies where the Health Plan requires it
- Coverage determinations do not guarantee payment and are subject to plan contract terms
Conservative Therapy Requirement
Conservative therapy must be attempted and documented before surgical intervention. Examples include use of nasal cones, external nasal dilator adhesive strips, or a six-week trial of nasal steroids.
- Document trials of outpatient nocturnal external stents (e.g., Breathe Right® nasal strips) or nasal dilators (e.g., Max-Air Nose Cones®, Sinus Cones®)
- Document duration and response to a six-week trial of nasal steroids when used
Required Clinical Documentation
Document clinical findings supporting nasal valve compromise and response to diagnostic maneuvers. Providers should record physical exam findings (e.g., internal or external valve collapse), results of the Cottle maneuver or lateralization tests, NOSE score when available, and that other causes of obstruction have been ruled out.
- Document location (unilateral vs bilateral) and duration of symptoms
- Document exclusion of other causes (sinusitis, allergic/nonallergic rhinitis, nasal polyps, septal deviation, turbinate hypertrophy)
- Document specific diagnostic tests used and their results (e.g., NOSE score, rhinomanometry, anterior rhinoscopy)
Denial Risk and Applicability
Procedures that do not meet the specified criteria in Section I or are listed as not medically necessary in Section II (e.g., VivAer® radiofrequency ablation, absorbable implants such as Latera®, nasal valve suspension) are at risk for denial. Providers are expected to exercise professional medical judgment; this policy is guidance and does not guarantee payment.
Background
Nasal valve compromise (NVC), also called nasal valve collapse, is a narrowing of the nasal passage that can cause obstructed breathing. Causes include structural weakness of the internal or external nasal valve (upper lateral cartilage or lower lateral cartilage), prior nasal surgery, trauma, chronic inflammation, congenital defects, or age-related changes. NVC may present as unilateral or bilateral nasal obstruction and is assessed by history, physical examination, maneuvers such as the Cottle test or manual lateralization, and adjunctive objective measures when indicated.

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
