Final answer:
Medical Assistants (CMAs) are required to recertify every 5 years to maintain their credentials and stay current with medical advancements.

The healthcare professional that must recertify their credentials every 5 years is the Medical Assistant (CMA). Recertification for CMAs is a requirement to ensure they maintain a certain level of expertise and stay updated with the latest medical practices and procedures.
