Summary & Overview
CPT 31200: Anterior Ethmoid Sinus Debridement, Intranasal
CPT code 31200 denotes an intranasal surgical approach to the anterior ethmoid sinus in which the surgeon makes an intranasal incision and removes all diseased material from the anterior ethmoid sinus. This code captures a common otolaryngology procedure for patients with refractory sinus disease or complications that require direct surgical clearance of the anterior ethmoid air cells. Nationally, accurate coding of 31200 matters for clinical documentation, resource allocation in ambulatory surgical centers and hospitals, and ensuring appropriate claims processing for sinus surgery.
Key payers examined in typical coverage analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on clinical intent and procedural setting, guidance on where the service is commonly performed, and notes about payer landscape and coverage implications. The publication also presents benchmarks for utilization and reimbursement patterns, highlights relevant policy updates that affect authorization and site-of-service determinations, and situates the code within clinical workflows for ENT surgical management.

Billing Code Overview
CPT code 31200 describes an intranasal surgical procedure to access and clear the anterior ethmoid sinus. The provider makes an intranasal incision to gain access into the anterior ethmoid sinus and then removes all diseased contents from the anterior ethmoid sinus.
-
Service type: Endoscopic or surgical sinus procedure involving intranasal incision and debridement of the anterior ethmoid sinus.
-
Typical site of service: Operating room or ambulatory surgical center; procedure performed via intranasal approach.
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to an otolaryngology clinic with a 3-month history of persistent nasal congestion, facial pressure, and purulent nasal drainage unresponsive to prolonged medical therapy including topical steroids and at least two courses of antibiotics. Endoscopic evaluation demonstrates polypoid and purulent disease localized to the anterior ethmoid region with obstruction of the ostiomeatal complex. CT sinus imaging confirms opacification of the anterior ethmoid air cells without intracranial extension. The provider schedules a functional endoscopic sinus surgery (FESS) procedure under general anesthesia to address refractory anterior ethmoid disease. Intraoperatively the surgeon makes an intranasal incision, gains access to the anterior ethmoid sinus, and removes diseased mucosa and retained secretions, restoring ventilation and drainage of the anterior ethmoid complex. Typical workflow includes preoperative evaluation by the surgeon and anesthesia team, informed consent documenting medical necessity, operating room time with endoscopic equipment, performance of the 31200 anterior ethmoidotomy, hemostasis, and postoperative instructions with short-term topical therapy and follow-up nasal endoscopy within 2–6 weeks. Typical site of service is an outpatient ambulatory surgery center or hospital operating room. Service type is operative endoscopic sinus surgery (anterior ethmoidotomy) performed by an otolaryngologist (ENT).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable E/M service on the same day | Use when a distinct preoperative or postoperative E/M by the same physician is documented on the day of surgery. (Note: 25 is not in the provided modifier list; see strict rules — therefore not used.) |
26 | Professional component | Use when billing only the professional component of a service (e.g., interpretation) performed by the physician. |
50 | Bilateral procedure | Use when the anterior ethmoidotomy is performed on both sides and payer requires bilateral modifier reporting. |
51 | Multiple procedures | Use when 31200 is reported with additional distinct surgical procedures during the same operative session. |
52 | Reduced services | Use when the procedure was partially reduced or not fully performed as documented. |
53 | Discontinued procedure | Use when the procedure was started but terminated due to extenuating circumstances. |
62 | Two surgeons | Use when two surgeons of different specialties work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team (multiple surgeons) | Use when a surgical team performs the procedure with members billing under team rules. |
78 | Return to operating room for a related procedure during the postoperative period | Use when a related unplanned reoperation is performed during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon participates and billing requires the assistant modifier. |
81 | Minimum assistant surgeon | Use when a minimal assistant role is documented and billing permits 81. |
82 | Assistant surgeon (when a qualified resident is unavailable) | Use when an assistant surgeon is necessary and no qualified resident is available. |
TC | Technical component | Use if only technical component of a bundled service is billed by a separate entity (e.g., facility billing for equipment/room). |
LT | Left side | Use to report procedures performed on the left side when side-specific modifiers are required. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207Y00000X | Otolaryngology (ENT) | Primary specialty performing 31200. |
207K00000X | Otolaryngology - Pediatric | Pediatric ENTs perform this procedure in children with refractory anterior ethmoid disease. |
207L00000X | Head and Neck Surgery | Surgeons with head and neck focus may perform endoscopic sinus procedures. |
163W00000X | Anesthesiology | Anesthesia providers supporting operative FESS. |
207V00000X | Facial Plastic Surgery | Facial plastic surgeons with rhinologic training may be involved in combined procedures. |
Note: From the raw modifier list, clinically most relevant modifiers for an operative anterior ethmoidotomy include 26, 50, 51, 52, 53, 62, 66, 78, 80, 81, 82, TC, and laterality modifiers such as LT/RT as shown above. Only the most applicable modifiers are listed with typical use cases.
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
J32.0 | Chronic maxillary sinusitis | Maxillary disease commonly coexists with anterior ethmoid disease and may influence need for concurrent maxillary antrostomy. |
J32.1 | Chronic frontal sinusitis | Frontal sinusitis can be associated with ostiomeatal complex obstruction requiring anterior ethmoid intervention. |
J32.2 | Chronic ethmoidal sinusitis | Directly related to disease of the ethmoid air cells addressed by 31200. |
J32.3 | Chronic sphenoidal sinusitis | May coexist with ethmoid disease in more extensive sinus surgery. |
J32.4 | Chronic pansinusitis | Diffuse sinus disease may require more extensive procedures than isolated anterior ethmoidotomy. |
J33.0 | Polyp of nasal cavity | Nasal polyps frequently involve the ethmoid region and are a common indication for ethmoidotomy when refractory to medical therapy. |
J01.90 | Acute sinusitis, unspecified | Acute exacerbations or unresolved acute disease affecting the ethmoid can lead to surgical intervention if complications or persistence occur. |
J01.01 | Acute maxillary sinusitis | Acute maxillary disease may accompany anterior ethmoid disease prompting combined management. |
