What are CPT® codes used for?

Current Procedural Terminology (CPT) is a medical coding set used to report medical, surgical, and diagnostic procedures to physicians and health insurance companies. CPT Codes are typically used during the medical billing processes.

The AMA is attacking dysfunction in health care by removing obstacles and burdens that interfere with patient care. Our focus is on making technology an asset in the delivery of health care, not a burden.
