Summary & Overview
CPT 31276: Frontal Sinus Endoscopy and Debridement
CPT code 31276 represents an endoscopic frontal sinus exploration and debridement procedure used to inspect the frontal sinus and remove bone, scar tissue, polyps, or other obstructing tissue. Nationally, this code captures a common otolaryngologic surgical intervention for chronic or recurrent frontal sinus disease and acute complications that require direct visualization and tissue removal. The code is relevant to hospital outpatient departments and ambulatory surgery centers where endoscopic sinus surgery is routinely performed.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise clinical context for the procedure, comparisons to related endoscopic sinus surgery codes, and typical service settings. The publication summarizes coding intent and clinical scope, highlights the most relevant associated diagnoses, and identifies related CPT procedures for ethmoid, maxillary, and sphenoid sinus surgery to aid coding alignment. It also outlines expected billing considerations such as common sites of service and where this code fits within the broader set of sinus endoscopy services.
The content is aimed at coding managers, clinical leaders, and revenue cycle professionals seeking a national overview of CPT 31276, its clinical role, and its place among related endoscopic sinus procedures.
Billing Code Overview
CPT code 31276 describes an endoscopic surgical procedure in which a provider inserts an endoscope into the frontal sinus to inspect for abnormalities and to remove bone, scar tissue, polyps, or other obstructing tissue. The procedure is a form of sinus endoscopy with frontal sinus exploration and debridement.
Service type: Endoscopic sinus surgical procedure (frontal sinus exploration/removal of tissue)
Typical site of service: Hospital outpatient department or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A 46-year-old patient with an 18-month history of recurrent frontal headaches, nasal obstruction, and purulent rhinorrhea presents to an otolaryngologist after failing prolonged medical therapy including intranasal corticosteroids and multiple antibiotic courses. CT imaging demonstrates opacification and narrowing of the frontal recess with bony partitions and polypoid mucosal disease consistent with chronic frontal sinusitis (J32.1) and pansinusitis (J32.4). The patient is scheduled for endoscopic frontal sinus exploration and debridement under general anesthesia.
Preoperative workflow includes history and physical, review of CT sinus imaging, informed consent specific to endoscopic frontal sinus surgery, perioperative antibiotics as indicated, and operative planning for possible extended frontal sinus dissection or frontal sinusotomy. Intraoperatively, the surgeon introduces a nasal endoscope through the nasal cavity into the frontal recess and frontal sinus (procedure 31276), evaluates anatomy, resects obstructing bone, scar tissue, or polyps, and restores drainage. Specimens may be sent for culture or pathology. Postoperative workflow includes recovery monitoring, nasal packing or splints as indicated, short-course oral antibiotics or topical therapy, and follow-up for endoscopic debridement and wound care in clinic.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, and complexity substantially exceed typical for 31276 and documented justification is present. |
52 | Reduced services | Use when the procedure is partially completed or limited versus full planned 31276. |
53 | Discontinued procedure | Use when 31276 is started but halted due to extenuating circumstances before completion. |
59 | Distinct procedural service | Use when 31276 represents a distinct endoscopic frontal sinus exploration performed separate from another unrelated procedure on the same day. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons on 31276 and documentation supports shared active participation. |
76 | Repeat procedure by same physician | Use when 31276 is repeated by the same physician in a separate session for the same patient. |
77 | Repeat procedure by another physician | Use when 31276 is repeated by a different physician in a separate session. |
78 | Unplanned return to OR for related procedure | Use when the patient returns to the operating room for a related complication after 31276 during the postoperative period. |
79 | Unrelated procedure or service by the same physician during postoperative period | Use when an unrelated procedure is performed during the global period of 31276. |
26 | Professional component | Use to indicate billing only for the professional component when technical services are billed separately for imaging or diagnostic components associated with care. |
TC | Technical component | Use to indicate billing only for the technical component when applicable for imaging or tests related to the episode. |
QK | Medical direction, more than four assistants | Use when medical direction of multiple qualified assistants is reported in services assisting with 31276 per payer rules. |
QX | Qualified nonphysician practitioner | Use when a qualified nonphysician practitioner performs part of the service under appropriate supervision rules. |
RT | Right side | Use to identify right-sided procedure when laterality reporting is required. |
LT | Left side | Use to identify left-sided procedure when laterality reporting is required. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207Y00000X | Otolaryngologist | Primary specialty that performs endoscopic sinus surgery including frontal sinus exploration. |
207YX0602X | Otolaryngology/Facial Plastic Surgery | Performs sinus endoscopy with potential concomitant nasal/plastics procedures impacting frontal recess anatomy. |
207YS0123X | Otolaryngology/Plastic Surgery within the Head & Neck | Subspecialty overlap for complex sinonasal and facial reconstructive cases involving frontal sinus work. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
J32.0 | Chronic maxillary sinusitis | Maxillary disease often coexists with frontal pathology; addressing maxillary outflow can be part of comprehensive endoscopic management. |
J32.1 | Chronic frontal sinusitis | Primary indication for 31276; reflects chronic inflammatory or obstructive disease of the frontal sinus requiring endoscopic exploration or debridement. |
J32.2 | Chronic ethmoidal sinusitis | Ethmoid disease can obstruct the frontal recess; ethmoidectomy may be performed to access and treat frontal sinus disease. |
J32.3 | Chronic sphenoidal sinusitis | Sphenoid involvement may coexist in pansinusitis; sphenoidotomy or exploration may be performed in the same operative session. |
J32.4 | Chronic pansinusitis | Diffuse sinonasal disease involving multiple sinuses that often necessitates multi-sinus endoscopic procedures including frontal sinus exploration. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
31255 | Nasal/sinus endoscopy, surgical with ethmoidectomy | Ethmoidectomy is commonly performed in the same operative setting to address obstructing disease that affects frontal recess access prior to or along with 31276. |
31267 | Nasal/sinus endoscopy, surgical with maxillary antrostomy | Maxillary antrostomy may be performed concurrently when maxillary sinus disease (e.g., J32.0) contributes to pansinusitis or obstructive pathology during frontal sinus surgery. |
31288 | Nasal/sinus endoscopy, surgical with sphenoidotomy | Sphenoidotomy is performed when sphenoidal disease (J32.3) is present and may be part of a comprehensive endoscopic sinus surgery including frontal exploration. |
31287 | Nasal/sinus endoscopy, surgical with sphenoid sinus exploration | Sphenoid sinus exploration codes relate when targeted evaluation or intervention in the sphenoid is needed in the same surgical episode as frontal sinus surgery. |
