Which organization is responsible for maintaining the CPT coding system?

The organization responsible for maintaining the Current Procedural Terminology (CPT) coding system is the American Medical Association (AMA). The AMA developed the CPT codes in the 1960s to provide a uniform language for reporting medical procedures and services. This system is crucial for accurately documenting healthcare services, facilitating billing processes, and supporting medical research and health care analysis. The AMA continuously updates and revises CPT codes to reflect new medical technologies, procedures, and services, ensuring that the coding system remains relevant and comprehensive for healthcare providers and insurers alike. This leadership role in maintaining and updating the CPT coding system underscores the AMA's commitment to enhancing healthcare communication and efficiency.

The other organizations listed have different functions; for instance, the World Health Organization (WHO) focuses on international public health, the Center for Medicare and Medicaid Services (CMS) manages national healthcare programs but does not create coding systems, and the National Institutes of Health (NIH) is primarily involved in biomedical and public health research. Hence, their roles do not encompass the maintenance of the CPT coding system.
