CPT 31242: Endoscopic Posterior Nasal Nerve Radiofrequency Ablation
CPT code 31242 covers endoscopic radiofrequency ablation of the posterior nasal nerve, a minimally invasive procedure used to reduce chronic nasal symptoms by targeting neural pathways. Nationally, this code is relevant as clinicians and payers evaluate coverage for procedures intended to treat refractory nasal congestion, rhinorrhea, or other neurogenic nasal conditions where conservative measures have failed. Adoption of endoscopic posterior nasal nerve ablation has implications for outpatient surgical volumes and payer policy decisions regarding minimally invasive otolaryngology interventions.
Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis addresses coverage and coding considerations that influence reimbursement, site-of-service patterns (ambulatory surgery centers, hospital outpatient departments, and select office-based settings), and how clinical indications align with billing for 31242.
Readers will find an operational overview of the procedure code, typical clinical context, common modifiers used with procedural billing, and where to expect this service to be delivered. The publication summarizes benchmarks and policy themes relevant to national stakeholders, highlights documentation and coding points that affect claims adjudication, and identifies areas where payer policy updates commonly appear. Data not available in the input are noted where applicable.

Billing Code Overview
CPT code 31242 describes an endoscopic intranasal procedure in which the provider inserts an endoscope into the nose and performs radiofrequency ablation of the posterior nasal nerve (destruction using heat from focused radio waves). This procedure is a minimally invasive surgical intervention targeting neural tissue to reduce nasal symptoms.
Service type: Endoscopic nasal procedure; radiofrequency ablation of posterior nasal nerve
Typical site of service: Ambulatory surgery center or hospital outpatient department; may also be performed in an office setting equipped for endoscopic procedures
Clinical & Coding Specifications
Clinical Context
A typical patient is a 35–65-year-old adult with chronic rhinitis characterized by persistent posterior nasal congestion, rhinorrhea, and nasal hypersensitivity despite maximal medical therapy (intranasal corticosteroids, antihistamines, and nasal anticholinergics). The patient presents to an otolaryngologist for evaluation. After history and nasal endoscopy confirm mucosal hypertrophy and symptoms attributable to posterior nasal nerve-mediated parasympathetic overactivity, the provider discusses minimally invasive options, including endoscopic posterior nasal nerve radiofrequency ablation (CPT 31242).
The clinical workflow includes pre-procedure evaluation (medical history, medication review, informed consent), topical and/or local anesthesia with or without conscious sedation, endoscopic nasal inspection, insertion of a nasal endoscope, and delivery of targeted radiofrequency energy to the posterior nasal nerve region to ablate nerve fibers. The patient is observed in the ambulatory surgery center or office procedure room depending on anesthesia needs, given post-procedure discharge instructions (nasal saline, activity restrictions, analgesia), and scheduled for follow-up to assess symptom improvement and complications such as bleeding or crusting.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or complexity substantially greater than typical for CPT 31242 (document justification). |
23 | Unusual anesthesia | Use when procedure performed under general anesthesia but normally done with local/regional anesthesia. |
50 | Bilateral procedure | Use when bilateral posterior nasal nerve ablation is performed and payer requires bilateral reporting (confirm payer rules). |
51 | Multiple procedures | Use when CPT 31242 is reported with additional separate procedures during same session (some payers require modifier). |
52 | Reduced services | Use when procedure is partially reduced or not completed as documented. |
59 | Distinct procedural service | Use to indicate a separate and distinct procedural service when another procedure might be considered bundled. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons on the procedure. |
66 | Surgical team | Use when services are performed by a surgical team. |
78 | Return to OR for related procedure during global period | Use if patient returns to OR for a related procedure during the global period. |
79 | Unrelated procedure during global period | Use if an unrelated procedure is performed during the global period (not in provided modifier list but commonly relevant). |
80 | Assistant surgeon | Use when assistant surgeon services are required and allowed by payor. |
AS | Ambulatory surgery center facility | Use to denote facility type when billing for facility services (if required by payer). |
LT | Left side | Use to identify left-sided service when laterality reporting is required. |
RT | Right side | Use to identify right-sided service when laterality reporting is required. |
