CPT code 0559T designates the preparation, processing and printing of the first 3D anatomic model of a body structure from one or more imaging data sets. As 3D anatomic modeling gains clinical traction for surgical planning, education, and device fitting, this code captures a distinct technical service that separates model fabrication from imaging acquisition and interpretation. Nationally, the code matters because it establishes a discrete billing pathway for additive manufacturing workflows tied to patient-specific care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what the code represents, payer coverage considerations, common modifiers reported with the service, and the clinical contexts in which models are typically used (surgical planning, complex anatomy visualization, and preoperative rehearsal).

The publication provides benchmarks and policy context relevant to hospitals and outpatient imaging centers performing 3D model fabrication. It summarizes typical sites of service, service definitions, and areas where payers and providers often focus review (medical necessity, relation to imaging and procedural services). Data not available in the input is noted where applicable.
