CPT, or Current Procedural Terminology, is a standardized coding system used by healthcare professionals to describe medical, surgical, and diagnostic services. Developed by the American Medical Association, CPT codes help ensure clear communication between providers, insurers, and patients regarding the services rendered. These codes are essential for billing and insurance purposes, as they provide a uniform language for reporting procedures and services. Each code corresponds to a specific service, making it easier for healthcare providers to document their work and for insurance companies to process claims accurately.
