Summary & Overview
CPT 31201: Endoscopic Intranasal Ethmoidectomy with Drain Placement
Headline: CPT code 31201: Endoscopic Intranasal Ethmoidectomy with Drain Placement
Lead: CPT code 31201 denotes an endoscopic intranasal procedure targeting the anterior and posterior ethmoid sinuses to remove diseased tissue and apply drains. The code captures a common surgical approach for management of ethmoid sinus disease and is relevant across hospital and ambulatory surgery settings nationally.
CPT code 31201 represents a surgical sinus procedure that is part of the broader set of endoscopic sinus surgeries used to address chronic rhinosinusitis and ethmoid disease. It matters nationally because it reflects a frequently performed otolaryngology intervention with implications for surgical resource use, facility planning, and payer coverage policies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for the procedure, typical sites of service, and the types of benchmarks and policy considerations commonly associated with this code. The publication summarizes service definitions, applicable care settings, and the operational considerations that payers and providers monitor, such as utilization patterns, site-of-service shifts, and prior authorization trends.
This overview is intended to orient clinicians, billing professionals, and policy analysts to the core attributes of CPT code 31201 and to highlight areas for further review in payer policy documents and facility billing guidelines.
Billing Code Overview
CPT code 31201 describes an endoscopic intranasal procedure to access the anterior and posterior ethmoid sinuses, remove diseased tissue, and place drains. This procedure is a sinus surgical intervention performed via an intranasal approach to treat chronic or acute sinus disease involving the ethmoid complex.
-
Service type: Endoscopic sinus surgery (intranasal ethmoidectomy)
-
Typical site of service: Hospital operating room or ambulatory surgery center, with potential admission to observation or inpatient setting based on patient condition and complexity.
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents with chronic sinonasal congestion, facial pressure, purulent anterior nasal drainage, and decreased olfaction despite maximal medical therapy including intranasal corticosteroids and a course of oral antibiotics. Nasal endoscopy and CT imaging demonstrate extensive inflammatory disease involving the anterior and posterior ethmoid sinuses with mucosal thickening, polypoid change, and obstructed sinus ostia. The otolaryngologist schedules an operative endoscopic intranasal procedure to open and clear the anterior and posterior ethmoid air cells, remove diseased mucosa and polyps, and place small intranasal drains or spacers to maintain postoperative drainage.
The typical clinical workflow includes preoperative evaluation with history, nasal endoscopy, and CT sinus imaging; informed consent that documents medical management failure; intraoperative endoscopic ethmoidectomy via an intranasal approach with removal of diseased tissue and placement of drains; postoperative instructions, nasal saline irrigations, and short-interval follow-up for debridement and drain removal. This procedure is commonly performed in an ambulatory surgery center or hospital outpatient setting under general anesthesia or monitored sedation depending on patient comorbidities.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the work, time, or technical difficulty of the ethmoidectomy significantly exceeds typical expectations and documentation supports increased complexity. |
