Summary & Overview
CPT 31075: Frontal Sinus Excision via Transorbital Approach
CPT code 31075 represents a surgical transorbital approach to the frontal sinus for excision of diseased tissue, including cysts and benign neoplasms. The code captures a specific operative technique used to access the frontal sinus through an incision along the inner orbital wall. Nationally, this code is relevant for surgical specialties managing sinonasal and orbital pathology and for facility and professional billing in operative settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines clinical context for the procedure, the typical sites of service (hospital operating room and ambulatory surgical center), and payer considerations that influence coding and billing workflows.
Readers will learn the clinical scope of CPT code 31075, common settings where the service is provided, and what benchmarks and policy topics are commonly relevant to this type of operative billing. The report also summarizes where to expect variability in coverage and administrative handling across major national payers. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 31075 describes a surgical procedure in which the provider makes an incision along the inner wall of the orbit to access the frontal sinus and remove diseased tissue, such as a cyst or benign neoplasm. This procedure is a form of frontal sinus exploration and lesion excision.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 45–65-year-old adult presenting with frontal sinus pathology such as a mucous retention cyst, benign neoplasm (eg, osteoma), chronic frontal sinusitis with localized mass effect, or recurrent mucocele. The patient reports frontal forehead pain, pressure, recurrent frontal sinus infections, or proptosis and diplopia if the lesion encroaches on the orbit. Preoperative evaluation includes nasal endoscopy, CT scan of the paranasal sinuses with coronal and axial views, ophthalmic examination when the orbit is involved, and routine preoperative labs and anesthetic assessment.
The clinical workflow: the patient is evaluated in otolaryngology or oculoplastic clinic; imaging confirms a frontal sinus lesion accessible via an external orbital approach. Informed consent and perioperative planning are completed. The procedure 31075 (external orbitotomy approach to frontal sinus with excision of lesion) is performed in an operating room under general anesthesia by an otolaryngologist, oculoplastic surgeon, or head and neck surgeon. Intraoperative steps include a subcutaneous or transconjunctival incision along the inner orbital rim, careful dissection to the frontal sinus, identification and excision of the cyst or benign neoplasm, hemostasis, possible sinus ostium management, and layered wound closure. Postoperative care includes monitoring for orbital complications, analgesia, antibiotic coverage if indicated, follow-up imaging or endoscopy, and outpatient clinic visits for suture removal and sinus surveillance.
