Summary & Overview
CPT 67450: Orbitotomy with Exploration and Biopsy
CPT code 67450 denotes an orbitotomy with exploration and biopsy — a surgical approach to the eye socket that removes a portion of orbital bone to examine and sample suspicious tissue. This procedure is clinically important for diagnosing orbital masses, infections, or inflammatory processes that cannot be characterized by imaging alone. Nationally, accurate reporting of 67450 supports appropriate surgical coding, claims processing, and diagnostic capture for ophthalmic and otolaryngologic surgical services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical sites of service, plus benchmarking context for utilization and payment practices where available. The material outlines coding scope, common procedural context, and what to expect in terms of surgical setting and diagnostic intent. Data not available in the input will be identified as such. The piece is intended for billing professionals, surgical coders, and clinical leaders seeking a national-level briefing on the use and classification of CPT code 67450 in descriptive and operational terms.
Billing Code Overview
CPT code 67450 describes an orbitotomy with exploration and biopsy. The procedure involves an incision through the lateral (side) wall of the orbit to remove a segment of bone as either a temporary bone flap or a permanent bone window to gain access to the orbital cavity. The surgeon explores the orbital contents, obtains tissue samples from suspicious lesions, and submits specimens for laboratory analysis.
Service type: Surgical — diagnostic exploration with biopsy of the orbit
Typical site of service: Hospital operating room or outpatient surgical center (ambulatory surgery center)
Clinical & Coding Specifications
Clinical Context
A 58-year-old female presents with progressive proptosis, periorbital pain, and decreased extraocular motility over several weeks. Imaging with contrast-enhanced CT and MRI demonstrates an intraorbital mass of unclear origin adjacent to the lateral orbit with possible bone remodeling. After multidisciplinary evaluation with ophthalmology and otolaryngology, the decision is made to perform an orbitotomy with bone window to obtain tissue for definitive histopathology. The surgical workflow includes general anesthesia, a lateral canthal or lateral eyelid crease incision, removal of a small segment of lateral orbital rim as a bone flap or window, intraoperative inspection of the orbital contents, biopsy or excision of suspicious lesion(s), hemostasis, and either replacement of the bone flap or leaving a bone window open per intraoperative judgment. Tissue specimens are submitted to surgical pathology with appropriate labeling and requisition. Postoperative management includes ophthalmic exams, imaging as indicated, pain control, antibiotic prophylaxis if used, and follow-up to review pathology and plan any adjunctive treatment such as radiation or systemic therapy.
