CPT code 21081 covers the fabrication of a mandibular resection prosthesis using an oral impression to support mandibular form and function after complex surgical resection. The code is clinically significant for maxillofacial surgery and prosthodontics because these prostheses facilitate wound healing, preserve facial contours, and support oral function during recovery. Nationally, this code intersects surgical, dental-prosthetic, and hospital billing pathways, making clear coding and site-of-service documentation important for accurate claims processing.

Key payers in typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers can expect a concise overview of coverage considerations across major commercial payers and Medicare, common clinical contexts for use of the code, and operational benchmarks for service delivery.
