CPT 31241: Endoscopic Sphenopalatine Artery Ligation for Epistaxis
CPT code 31241 represents an endoscopic nasal surgical procedure in which the sphenopalatine artery (SPA) is ligated or occluded via endoscopic access through a nostril to control epistaxis or hemorrhage during tumor removal. Nationally, this code is important for otolaryngology surgical billing because it captures definitive, procedural management of posterior nasal bleeding and intraoperative bleeding control during sinonasal tumor resections. Proper coding affects facility and professional payment alignment for endoscopic sinus and skull base services.
Key payers commonly included in coverage discussions are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis typically addresses facility and surgeon billing, site-of-service implications, and documentation elements that support medical necessity for arterial ligation procedures.
Readers will learn clinical context for when CPT code 31241 is used, typical sites of service, payer coverage considerations, and common documentation points tied to procedural indication (epistaxis control or hemorrhage management during tumor removal). Data elements such as payer-specific coverage policies, reimbursement benchmarks, and coding guidance are addressed where available. Data not available in the input will be identified as such in relevant sections.

Billing Code Overview
CPT code 31241 describes an endoscopic nasal procedure in which a provider inserts an endoscope through a nostril to examine the nasal cavity and sinuses and ties off the sphenopalatine artery (SPA) to control epistaxis or to control bleeding during tumor removal. This is an endoscopic sphenopalatine artery ligation or occlusion procedure.
-
Service type: Endoscopic nasal surgical procedure for arterial ligation to control bleeding
-
Typical site of service: Hospital operating room or ambulatory surgical center, with endoscopic access via the nasal cavity
Clinical & Coding Specifications
Clinical Context
A 46-year-old patient presents to the otolaryngology clinic with recurrent, severe posterior epistaxis refractory to anterior packing and topical vasoconstrictors. After failed conservative measures and persistent bleeding, the patient is taken to the operating room for endoscopic evaluation. Under general anesthesia, the surgeon introduces a nasal endoscope through a nostril to inspect the nasal cavity and posterior choanae, identifies active bleeding from branches of the sphenopalatine artery, and performs endoscopic ligation/occlusion of the sphenopalatine artery (CPT 31241). Hemostasis is confirmed endoscopically. Typical workflow includes preoperative assessment and imaging as needed, intraoperative endoscopic visualization and SPA ligation, hemostasis verification, and postoperative monitoring in the PACU with instructions for nasal care and follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Provider does not use a modifier | Rarely used; include only per payer policy when no modifier applies |
11 | Normal, everyday physician service | When the procedure is performed without complication and represents the usual service |
22 | Increased procedural services | Use when work or complexity substantially exceeds the typical service (document increased work) |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for a procedure normally done with local anesthesia |
26 | Professional component | Use when reporting only the physician’s professional component separate from technical services |
51 | Multiple procedures | When CPT 31241 is performed with additional unrelated procedures during the same session |
52 | Reduced services | When the procedure is partially reduced or not completed (document reason) |
53 | Discontinued procedure | When the procedure is terminated due to extenuating circumstances after anesthesia induction |
59 | Distinct procedural service | When a separate, distinct procedure is performed on the same day (use to indicate distinct anatomic site or separate session) |
62 | Two surgeons | When two surgeons work together as primary surgeons on the procedure |
63 | Procedure performed on infants less than 4 kg | Use for neonates/very low weight infants when applicable |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use if patient returns to OR for recurrent bleeding related to initial SPA ligation |
80 | Assistant surgeon | When a surgical assistant is required and documented |
TC | Technical component | When billing the technical component only (facility supplies/equipment) |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
208100000X | Otolaryngology (ENT) | Primary specialty performing endoscopic SPA ligation |
207L00000X | Head and Neck Surgery | Surgeons focusing on complex sinonasal/skull base procedures |
207P00000X | Facial Plastic Surgery | May participate when tumor resection with bleeding control is required |
2080S0123X | Rhinology (subspecialty of Otolaryngology) | Subspecialists who frequently perform endoscopic sinus and SPA procedures |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I98.11 | Epistaxis (posterior) | Posterior epistaxis is the primary indication for endoscopic sphenopalatine artery ligation |
R04.0 | Epistaxis | General epistaxis diagnosis used when documentation does not specify posterior vs anterior bleeding |
D35.2 | Benign neoplasm of nasal cavity and middle ear | Tumors in the nasal cavity may require resection with SPA control for bleeding management |
C30.0 | Malignant neoplasm of nasal cavity | Malignancy with intraoperative bleeding may require SPA ligation during tumor removal |
H72.9 | Eustachian tube disorders, unspecified (example comorbidity) | Comorbid ENT diagnoses that may coexist; not a direct indication but relevant in ENT practice |
