Billing Code Overview

CPT code 31292 describes endoscopic orbital decompression targeting the medial or inferior orbital wall. The procedure involves decompressing either the medial or inferior wall of the orbit performed during rigid or flexible endoscopy, typically to relieve orbital pressure or proptosis associated with orbital disease.

Service Type: Endoscopic orbital decompression (procedural surgery)

Typical Site of Service: Hospital outpatient department or ambulatory surgical center, performed in an operating room or endoscopy suite under appropriate anesthesia.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult referred to an otolaryngologist or oculoplastic surgeon for endoscopic orbital decompression due to symptomatic compressive optic neuropathy, proptosis from Graves orbitopathy, traumatic orbital fracture with entrapment causing orbital compartment syndrome, or progressive vision loss from orbital inflammation. The patient presents with visual changes (decreased acuity, color vision loss), pain, worsening proptosis, chemosis, or limited extraocular motility. Preoperative workup includes ocular examination with visual acuity, color vision, pupillary testing, intraocular pressure, formal visual fields or OCT when indicated, CT or MRI of the orbits to evaluate bone anatomy and compressive pathology, and medical optimization (e.g., control of thyroid status, corticosteroid therapy if inflammatory).

The procedure 31292 is performed in an operating room or ambulatory surgery center under general anesthesia or monitored anesthesia care. Using rigid or flexible endoscopy, the surgeon decompresses the medial or inferior orbital wall by removing bone and/or opening the periorbita to allow orbital fat prolapse and reduce orbital pressure. Intraoperative steps include nasal endoscopic access, identification of lamina papyracea or orbital floor, controlled removal of bone, protection of the globe and optic nerve, hemostasis, and possible placement of packing or drains. Postoperative care includes ophthalmologic assessment, pain control, avoidance of nose-blowing, short course of antibiotics when indicated, and follow-up imaging or clinical exams to document reduced proptosis and improved optic nerve function. Typical sites of service are ambulatory surgery centers or hospital operating rooms depending on case complexity and patient comorbidities.
