Summary & Overview
CPT 31230: Maxillectomy with Orbital Exenteration, Combined Resection
CPT code 31230 denotes a complex ablative surgery entailing removal of the maxilla and the orbital contents as a single unit. This procedure is typically performed for locally advanced malignancy, severe trauma, or destructive infectious processes that involve both the maxillary skeleton and the orbit. Nationally, the code represents high-acuity craniofacial care with implications for surgical resource use, multidisciplinary management, and post-acute rehabilitation.
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 context, typical sites of service, and the major billing and coding considerations associated with this high-complexity procedure. The publication outlines expected use cases, common modifiers in payer practice (input provided), and areas where policy clarification or preauthorization patterns commonly arise.
The report is intended for health system coders, surgical teams, revenue cycle staff, and policy analysts seeking a national-level synopsis of CPT code 31230. It summarizes what the code represents, where it is typically performed, and the practical billing context clinicians and administrators should expect when this major ablative craniofacial procedure is billed.
Billing Code Overview
CPT code 31230 describes a surgical procedure in which the provider performs removal of the maxilla (upper jaw) together with the contents of the eye’s orbit as a single unit. This is a combined maxillectomy and orbital exenteration performed for extensive disease processes involving both the maxillary skeleton and orbital contents.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with extensive maxillofacial malignancy or severe traumatic destruction involving the upper jaw and ipsilateral orbital contents where disease or injury is not salvageable. The patient often presents with pain, disfigurement, ocular dysfunction, recurrent infection, or local tumor invasion threatening adjacent structures. Preoperative workup includes CT/MRI of the face and orbits, ophthalmologic and dental evaluations, oncologic staging when applicable, and multidisciplinary planning with otolaryngology–head & neck surgery, maxillofacial surgery, ophthalmology, and reconstructive/plastic surgery. Surgery is performed in an operating room under general anesthesia, often requiring blood products, intraoperative pathology, and possible immediate reconstruction with free tissue transfer or obturator prosthesis. Postoperative care includes inpatient monitoring for airway and flap viability, pain control, infectious prophylaxis, and coordination of adjuvant therapy such as radiation or chemotherapy when indicated.
