Current Procedural Terminology (CPT) is a code set that is used to report medical procedures and services to entities such as physicians, health insurance companies and accreditation organizations. CPT is used in conjunction with ICD-9-CM or ICD-10-CM numerical diagnostic coding during the electronic medical billing process.
There are three types of CPT codes. Category 1 covers vaccines, Category 2 deals with performance measurement and Category 3 covers emerging technologies, services and procedures. The current version is known as CPT 2010.
