Maxillary Resection Prosthesis

A maxillary resection prosthesis is a custom-fabricated prosthetic appliance designed to seal and restore defects in the upper jaw and palate that result from surgical resection. These defects most commonly arise from the treatment of oral or sinonasal cancers, though they may also result from trauma or congenital conditions. Without this prosthesis, patients experience significant difficulty with speech, swallowing, and nasal regurgitation of food and liquids. The device effectively separates the oral cavity from the nasal cavity and maxillary sinus, restoring function that would otherwise be severely impaired.

The billing lifecycle for a maxillary resection prosthesis is more complex than most dental procedures because it typically involves three distinct phases. The surgical obturator is placed at the time of surgery to protect the wound and provide immediate function. The interim obturator is fabricated during the healing period as tissues change shape. The definitive prosthesis is created once surgical sites have fully healed and tissue contours have stabilized. Each phase has its own CDT code, and billing teams must track the timeline carefully to ensure each claim is submitted at the appropriate stage. Payers that cover maxillofacial prosthetics expect clear documentation of the phase of treatment and the clinical rationale for each device.

Reimbursement for maxillary resection prostheses often requires coordination between dental and medical benefit plans. Many dental plans exclude maxillofacial prosthetics from coverage, pushing the claim to the medical side. Medical payers, in turn, may require CPT codes for certain components of care. Practices must be prepared to submit claims with complete narratives, operative reports, and clinical photographs that demonstrate the size and nature of the defect. Because these prostheses are among the highest-fee items in prosthodontic practice, ensuring clean claims and thorough pre-authorization workflows has a direct and meaningful impact on practice revenue.
