Coverage Determination for Ablation Therapies
General coverage determination
Covered when ALL of the following are met
BCBSNC does not provide coverage for investigational services or procedures.
Cryoablation, radiofrequency ablation, and laser ablation for the treatment of chronic rhinitis (allergic or nonallergic) are considered investigational for all applications. BCBSNC does not provide coverage for investigational services or procedures and claims for these procedures may be denied.
This policy does not designate any clinical scenario in which cryoablation, radiofrequency ablation, or laser ablation for chronic rhinitis is considered medically necessary. Instead, all applications of these posterior nasal nerve ablation techniques for chronic rhinitis are classified as investigational and are therefore not covered.

Provider Responsibilities and Medical Necessity Review
Coding and medical necessity review — inclusion of codes does not guarantee reimbursement
Inclusion of codes in the Billing/Coding section does not guarantee reimbursement; services will be subject to medical necessity review and may require submission of medical records for review. The applicable service codes listed are 30117, 30999, 31242, 31243, and 31299.
Step therapy / other prior authorization requirements
(Placeholder) No step therapy requirements are specified in this policy.
Medical records may be requested — include full documentation for medical necessity review
BCBSNC may require additional documentation or records to determine coverage. When records are requested, include all specific clinical information needed to make a medical necessity determination; letters of support or explanation can be useful but are not sufficient by themselves unless they contain all required information.
- BCBSNC may request medical records for determination of medical necessity
- Letters of support/explanation are often useful but not sufficient unless they include all required information
Investigational services denied — services are noncovered and may be denied
Because cryoablation, radiofrequency ablation, and laser ablation for treatment of chronic rhinitis (allergic or nonallergic) are considered investigational, BCBSNC does not provide coverage for these services; claims for investigational services will be denied.
- Policy statement: these ablation therapies are considered investigational for all applications
- BCBSNC does not provide coverage for investigational services or procedures — will trigger denial
Clinical Background
Chronic rhinitis—whether allergic, nonallergic, or mixed—can substantially impair quality of life and is primarily managed with medical therapies such as topical intranasal corticosteroids, anticholinergics, decongestants, and antihistamines. A subset of patients (approximately 10%–22%) have persistent symptoms despite medical therapy and are described as having refractory chronic rhinitis. Posterior nasal nerve ablation techniques (cryoablation, radiofrequency, laser) aim to reduce parasympathetic-mediated nasal secretions by interrupting efferent innervation, but these approaches are considered investigational for treating chronic rhinitis.
Key Definitions
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.
