Which one of the following groups is responsible for developing and updating CPT codes?

The group responsible for developing and updating CPT (Current Procedural Terminology) codes is the American Medical Association (AMA). This organization has taken on the task of maintaining the CPT code set to ensure it is accurate and reflective of current medical practices and procedures.

CPT codes are essential for billing and coding in medical practices, as they provide a uniform language for reporting medical services and procedures. The AMA collaborates with various stakeholders in the healthcare system, including physicians, providers, and payers, to ensure the codes are relevant and up-to-date.

Understanding the role of the AMA in this context is crucial for those involved in medical office management, as they need to keep abreast of changes in coding for accurate billing and compliance. Other organizations listed, such as AHIMA (American Health Information Management Association) and AAMA (American Association of Medical Assistants), play important roles in health information management and professional practice but do not oversee the development of CPT codes. CMS (Centers for Medicare & Medicaid Services) focuses on payment policies and regulations rather than the creation of coding systems.
