What is Current Procedural Terminology?
Current Procedural Terminology is a medical code set used to describe medical, surgical, and diagnostic services. These codes ensure uniform communication between healthcare providers, insurance companies, and billing departments.
CPT codes are widely used in the United States for medical billing and documentation. They help standardize reporting and simplify reimbursement processes.
Who Publishes Current Procedural Terminology?
American Medical Association publishes and maintains the Current Procedural Terminology code set. The AMA updates the CPT code book annually to reflect new medical procedures, technology advancements, and regulatory changes.
The official CPT manual is released every year, including updated guidelines and revised codes for accurate billing practices.
History of Current Procedural Terminology
CPT was first introduced in 1966 to standardize reporting of medical procedures. Over time, it evolved into the primary coding system for outpatient and physician services.
With continuous updates, the CPT system now reflects modern healthcare practices, telemedicine services, and digital health advancements.
What Are CPT Codes?
CPT codes are five-digit numeric codes that represent medical services and procedures. These codes are used for billing insurance providers and documenting patient care.
There are three main categories of CPT codes that classify different types of services provided in healthcare settings.
The 3 Categories of CPT Codes
Category I Codes
These are the most commonly used CPT codes. They represent medical procedures, surgeries, evaluations, and diagnostic services.
Category II Codes
These are optional performance measurement codes used for quality reporting and tracking patient outcomes.
Category III Codes
These temporary codes are assigned to emerging technologies and experimental procedures.
Six Sections of Current Procedural Terminology
CPT Category I codes are divided into six main sections:
Section | Description |
Evaluation & Management | Office visits and consultations |
Anesthesia | Anesthesia services during procedures |
Surgery | Surgical procedures |
Radiology | Imaging services |
Pathology & Laboratory | Lab testing services |
Medicine | Immunizations, therapy, and other medical services |
These sections help organize CPT codes efficiently for medical billing professionals.
5 Common CPT Codes

CPT Code | Description |
99213 | Established patient office visit (moderate complexity) |
99214 | Established patient visit (higher complexity) |
93000 | Electrocardiogram (ECG) |
