Current Procedural Terminology (CPT®), Fourth Edition, is a listing of descriptive terms and identifying codes for reporting medical services and procedures performed by physicians and other qualified health care professionals. The purpose of the terminology is to provide a uniform language that will accurately describe medical, surgical, and diagnostic services, and will thereby provide an effective means for reliable nationwide communication among physicians and other qualified health care professionals, patients, and third parties. CPT 2019 is the most recent revision of a work that first appeared in 1966.
CPT descriptive terms and identifying codes currently serve a wide variety of important functions in the field of medical nomenclature. The CPT code set is useful for administrative management purposes such as claims processing and for the development of guidelines for medical care review. The uniform language is also applicable to medical education and outcomes, health services, and quality research by providing a useful basis for local, regional, and national utilization comparisons. The CPT code set is the most widely accepted nomenclature for the reporting of physician and other qualified health care professional procedures and services under government and private health insurance programs. In 2000, the CPT code set was designated by the Department of Health and Human Services as the national coding standard for physician and other health care professional services and procedures under the Health Insurance Portability and Accountability Act (HIPAA). This means that for all financial and administrative health care transactions sent electronically, the CPT code set will need to be used.
