Coverage Criteria for Repair of Nasal Valve Compromise
Medically Necessary Repair of Nasal Valve Compromise
Covered when ALL of the following are met
Supported by policy criteria I.A.1-2
From policy criteria I.B
From policy criteria I.C
From policy criteria I.D
Procedures Considered Not Medically Necessary
Not medically necessary when
Listed in policy II.A-C
Radiofrequency ablation (VivAer), absorbable implants (Latera), and nasal valve suspension surgery are considered not medically necessary for repair of nasal valve compromise because safety and efficacy have not been established.
To clarify, the policy specifically lists radiofrequency ablation (VivAer®), absorbable implants (Latera®), and nasal valve suspension surgery as procedures that do not meet medical necessity criteria for repair of nasal valve compromise based on currently available evidence and review findings.
All coverage determinations are made in the context of the member's benefit documents and applicable law. Coverage decisions are subject to the terms, conditions, exclusions, and limitations of the coverage documents (e.g., evidence of coverage, certificate of coverage, policy, contract of insurance) and to state and federal requirements, including any applicable Medicaid provisions and Medicare NCDs/LCDs that may override this policy.
Codes and Coding Guidance
| 30465 | Repair of nasal vestibular stenosis (e.g., spreader grafting, lateral nasal wall reconstruction). |
Provider Actions, Prior Authorization, and Documentation
Prior authorization required; 30465 supports coverage, 30468/30469 do not
Prior authorization is required for procedures billed with the CPTs referenced in this policy. CPT 30465 (Repair of nasal vestibular stenosis) supports coverage when the policy criteria are met; CPTs 30468 and 30469 are listed as codes that do not support coverage.
- Supported code: 30465 — Repair of nasal vestibular stenosis (e.g., spreader grafting, lateral nasal wall reconstruction).
- Not supporting codes: 30468 — Repair of nasal valve collapse with subcutaneous/submucosal lateral wall implant(s); 30469 — Repair of nasal valve collapse with low energy, temperature-controlled (radiofrequency) subcutaneous/submucosal remodeling.
Prior authorization decisions subject to plan terms and medical necessity review
Coverage decisions are made according to the member's coverage documents and may require review against medical necessity criteria; providers should review applicable NCDs/LCDs and plan terms prior to applying the policy.
- Coverage and benefit administration are subject to all terms, conditions, exclusions and limitations of the coverage documents (e.g., evidence of coverage, certificate of coverage, policy, contract of insurance).
- For Medicare members, review applicable NCDs, LCDs, and Medicare Coverage Articles prior to applying criteria; state Medicaid provisions take precedence for Medicaid members.
Trial of conservative therapies required before surgery
Conservative therapies must be tried and symptoms must persist despite them before surgical repair is considered medically necessary.
- Examples of conservative therapy: nasal cones (Max-Air Nose Cones, Sinus Cones), external nasal dilator adhesive strips (Breathe Right), or a six-week trial of nasal steroids.
- Outpatient nocturnal trials of external stents or nasal dilators are acceptable demonstrations of conservative therapy.
Required clinical documentation for authorization
Clinical documentation submitted for authorization should demonstrate objective clinical findings of nasal valve compromise, patient-reported obstructed breathing that improves with the Cottle maneuver or lateralization or with trial of external/internal dilators, exclusion of other causes, and persistence of symptoms despite conservative treatment.
- Document internal valve collapse or compromise of the upper lateral cartilage or external nasal valve compromise due to collapse of the lower lateral cartilage.
- Document that obstructed breathing resolves with the Cottle maneuver, lateralization, or improvement with trials of external stents/nasal dilators.
- Document evaluation ruling out other causes (e.g., sinusitis, allergic/nonallergic rhinitis, nasal polyps, adenoid hypertrophy, nasopharyngeal masses, septal deviation, turbinate hypertrophy).
- Document prior conservative treatments and their duration (e.g., six-week trial of nasal steroids).
Do not bill non-covered procedure codes (30468, 30469)
Do not bill for procedures using subcutaneous/submucosal lateral wall implants (30468) or low-energy temperature-controlled radiofrequency subcutaneous/submucosal remodeling (30469) for repair of nasal valve compromise — these codes are listed as not supporting coverage and may result in claim denial.
Denial risk if claims do not conform to policy or coverage terms
Claims that do not meet the policy criteria or that conflict with member coverage documents, state Medicaid provisions, or applicable Medicare NCDs/LCDs are at risk of denial.
Provider actions to support authorization and correct coding
Follow the policy criteria when seeking authorization: confirm clinical findings of internal or external nasal valve compromise, document symptom response to maneuvers or dilators, rule out other causes, and record prior conservative treatments; ensure appropriate CPT coding (30465 when criteria met).
- Use CPT 30465 when documentation meets all coverage criteria.
- Do not use CPTs 30468 or 30469 for procedures intended to repair NVC, as they do not support coverage.
- Include objective tests or maneuvers (e.g., Cottle's maneuver, NOSE score, nasal endoscopy) as applicable in the record submitted for review.
Document clinical judgment and follow applicable Medicaid/Medicare rules
Providers must exercise professional medical judgment and document diagnosis and treatment decisions; state Medicaid provisions and Medicare NCDs/LCDs take precedence where applicable and should be reviewed prior to applying this clinical policy.
- Document rationale for diagnosis and chosen treatment in the medical record.
- For Medicaid members, state Medicaid coverage provisions override this policy when in conflict; for Medicare members, review applicable NCDs/LCDs.
Definitions
Background
Nasal valve compromise (NVC) is a narrowing or collapse of the nasal valve region—either internal (upper lateral cartilage) or external (lower lateral cartilage)—that produces obstructed nasal breathing and may arise from structural weakness due to trauma, prior surgery, chronic inflammation, congenital defects, or aging. NVC is a contributing cause in a minority of patients with chronic nasal obstruction; up to 13% of such patients may have NVC. Diagnosis combines history and physical exam maneuvers (for example, the Cottle maneuver), patient-reported measures (e.g., NOSE score), objective testing (rhinomanometry, acoustic rhinometry, peak nasal airflow), endoscopy or imaging as indicated, and trials of external or internal nasal dilators. Surgical repair typically aims to support weakened lateral or alar structures (for example with cartilage grafts) and may be performed along with correction of septal deviation or turbinate hypertrophy when those conditions contribute to obstruction.
