Mandibular Resection Prosthesis

A mandibular resection prosthesis is a specialized maxillofacial prosthetic appliance fabricated for patients who have undergone partial or complete removal of the lower jaw. This type of surgery, known as a mandibulectomy, is most commonly performed to treat oral cancers, aggressive benign tumors such as ameloblastoma, or severe osteoradionecrosis. The prosthesis serves to restore chewing function, speech, swallowing ability, and facial symmetry that are compromised when a segment of the mandible is absent.

Billing for mandibular resection prostheses presents unique revenue cycle challenges. These cases typically involve both dental and medical insurance, and the distinction between what each plan covers must be clearly understood by the billing team. The prosthetic device itself is generally billed using CDT codes in the D5900 series for maxillofacial prosthetics, while the surgical procedure may be billed under medical CPT codes. Pre-authorization is almost always required, and payers frequently request extensive supporting documentation including surgical reports, pathology results, diagnostic imaging, and a letter of medical necessity from the treating surgeon and prosthodontist.

Because mandibular resection prostheses involve multiple appointments for impressions, fittings, adjustments, and follow-up care, practices must carefully track each visit and associate it with the correct billing codes. The fabrication process is labor-intensive and material costs are significant, making accurate fee scheduling critical. Denials in this category are common when documentation fails to establish the connection between the surgical defect and the functional need for the prosthesis. Practices specializing in maxillofacial prosthetics benefit from having dedicated billing staff trained in both CDT and CPT coding systems to navigate these complex cases and maximize collections.
