Medical necessity guidelines for surgical and device-based repair of nasal valve compromise (internal and external) for members of Centene-affiliated health plans; describes covered procedures, excluded procedures, and required diagnostic/supporting evidence.
Added nasal dilators such as Max-Air Nose Cones and Sinus Cones to conservative treatment examples in criteria I.B and I.D.
CPT code 30469 (radiofrequency remodeling) added to Codes That Do Not Support Coverage.
Coverage Criteria — Repair of Nasal Valve Compromise
inv-01: Medically Necessary — Repair of Nasal Valve Compromise
Covered when ALL of the following are met:
Documented by physical exam and/or maneuvers (see required documentation).
Improvement should be documented in the clinical record.
Documentation of evaluation and findings required.
Conservative treatments attempted and dates/response must be documented.
inv-02: Not Established / Experimental Procedures for Nasal Vestibular Stenosis
The following procedures/devices have not established safety and efficacy for repair of nasal vestibular stenosis:
These procedures/devices are considered to lack established safety and/or efficacy per the policy and evidence reviews.
The policy identifies specific procedures and devices for which the available evidence is insufficient to establish safety and efficacy for repair of nasal vestibular stenosis. Per the evidence reviews cited in the source material, VivAer (low-energy radiofrequency remodeling) has only minimal support from clinical studies of mixed and generally poor quality, with uncertain effects on objective measures of nasal patency and no direct comparisons to active treatments. Similarly, absorbable nasal implants (Latera) are technically feasible and may reduce patient-reported obstruction in some uncontrolled studies, but the evidence base is generally very poor, lacks adequate control groups, and provides limited long-term follow-up. For these reasons the policy considers VivAer and Latera to have insufficient evidence to be established treatments for nasal valve repair and does not support their routine use for this indication.
Coverage determinations under this clinical policy are guidance to assist in making medical necessity decisions and administering benefits; they do not constitute a contract or guarantee of payment. All coverage decisions remain subject to the member’s specific plan terms, conditions, exclusions and limitations, as well as applicable state and federal requirements and Health Plan-level administrative policies and procedures. When program-specific rules (for example, state Medicaid manuals or Medicare NCDs/LCDs) conflict with this policy, the applicable program requirements take precedence.
The policy distinguishes covered surgical repair techniques from procedures and devices that lack established efficacy. It notes that radiofrequency remodeling (VivAer) is an office‑based, low‑energy RF treatment intended to stiffen and reposition intranasal soft tissues but that clinical evidence is limited and of variable quality. The policy also describes absorbable implants (Latera) as an endonasally placed, absorbable lateral wall implant that is replaced over time by fibrous tissue, but available studies are generally poor in quality and insufficient to demonstrate long‑term clinical benefit. Finally, nasal valve suspension surgery is listed among procedures without established safety and efficacy for nasal vestibular stenosis. These named procedures/devices are therefore considered not supported by the policy for routine repair of nasal valve compromise.

Provider Actions — Authorization, Documentation, and Denials
Prior authorization required for CPT 30465
Prior authorization is required for procedures to repair nasal vestibular stenosis that meet the policy's coverage criteria; CPT code 30465 (Repair of nasal vestibular stenosis spreader grafting, lateral nasal wall reconstruction) supports coverage when all policy criteria are met.
- Prior authorization required when submitting CPT 30465 for repair of nasal vestibular stenosis.
Policy guides coverage decisions; follow plan administrative rules
This clinical policy is intended to provide medical necessity guidance to assist in making coverage decisions and administering benefits; providers should follow applicable Health Plan-level administrative policies and prior authorization processes when seeking coverage.
- Policy is guidance—not a guarantee of payment; follow Health Plan administrative policies and prior authorization requirements.
Document prior conservative therapy trial(s)
Providers must document that symptoms persisted despite conservative management. Acceptable conservative therapy examples include nasal cones, external nasal dilator adhesive strips (e.g., Breathe Right), a six‑week trial of nasal steroids, or outpatient nocturnal trials of nasal dilators such as Max‑Air Nose Cones and Sinus Cones.
- Document trial and response to at least one conservative therapy (nasal cones, external dilator strips, six‑week nasal steroid trial, or nasal dilators such as Max‑Air Nose Cones and Sinus Cones).
No specific action listed
No additional provider action specified in source document for this placeholder; follow the other listed documentation and authorization requirements in this policy.
Required clinical history, exam, and test documentation
Clinical documentation must include a thorough history and physical exam of the nose and nasopharynx and results of indicated maneuvers/tests (e.g., Cottle's maneuver, Bachman's maneuver, NOSE score, rhinomanometry, nasal endoscopy, and CT if obtained). Documentation must also show that other causes of obstruction were ruled out and record prior conservative therapy trials.
- Include time course, laterality, triggers, trauma/surgical history, and relevant medical history in the record.
- Record results of Cottle's maneuver, Bachman's maneuver, NOSE score, rhinomanometry, nasal endoscopy, CT if obtained, and documentation excluding other causes of obstruction.
- Document prior conservative therapies and their duration/response.
Follow payer- and program-specific precedence and guidance
When state Medicaid provisions conflict with this policy, state Medicaid coverage provisions take precedence; for Medicare members, review all applicable NCDs, LCDs, and Medicare Coverage Articles to ensure consistency with this policy before making coverage determinations.
- Refer to the state Medicaid manual for Medicaid coverage provisions that may supersede this policy.
- Review applicable Medicare NCDs, LCDs, and Coverage Articles on the CMS website for Medicare members.
Denial triggers for insufficient documentation or non‑covered codes
Claims or authorization requests may be denied if documentation does not meet all clinical criteria — including objective findings of internal or external valve compromise, positive response to Cottle or lateralization maneuvers or outpatient trial of stents/dilators, exclusion of other causes of obstruction, and documented persistence despite conservative therapy — or if procedures/CPT codes listed as not supporting coverage (e.g., 30468, 30469) are used.
- Denial risk if objective valve compromise is not documented or if maneuvers/tests do not demonstrate improvement.
- Denial risk if other causes of obstruction are not ruled out or conservative therapy trials are not documented.
- Denial risk if CPT codes 30468 or 30469 (listed as not supporting coverage) are billed for repair.
Decisions subject to coverage documents, exclusions, and limitations
Coverage decisions and the administration of benefits are subject to all terms, conditions, exclusions, and limitations of the coverage documents; failure to meet those contractual terms may result in denial of coverage.
- Decisions are governed by evidence of coverage, certificates of coverage, policy contracts, and applicable state and federal requirements.
- Contractual exclusions and limitations in the member's coverage document may override policy indications.
Background — Nasal Valve Compromise
Nasal valve compromise (NVC) refers to structural narrowing of the nasal inlet that impedes airflow and contributes to chronic nasal obstruction. NVC may result from weakness or collapse of the upper lateral cartilage (internal nasal valve) or collapse of the lower lateral cartilage/alar rim (external nasal valve), and can arise from trauma, prior surgery, chronic inflammation, congenital anatomy, or age‑related changes. Symptoms commonly include difficulty inhaling through the nose, nasal congestion, and snoring; objective assessment can include exam maneuvers such as the Cottle or lateralization test, patient‑reported outcome measures (e.g., NOSE score), rhinomanometry, endoscopy, or CT when indicated. The policy notes that up to 13% of patients evaluated for chronic nasal obstruction may have nasal valve compromise, underscoring the clinical relevance of accurate diagnosis and documentation.
