Current Procedural Terminology (CPT) Current Procedural Terminology (CPT) is a medical code set that is used to report medical, surgical, and diagnostic procedures and services to entities such as physicians, health insurance companies and accreditation organizations.
CPT (Current Procedural Terminology) codes are numbers assigned to every task and service a medical practitioner may provide to a patient including medical, surgical, and diagnostic services. A CPT code looks like a five-digit alphanumeric code with no decimal marks. Most CPT codes consist of 5 numbers. Some are used frequently like 99213 or 99214 (for general check ups). Some CPT codes may have a letter at the end of them, using 4 numbers and one letter.
