Fla. Stat. § 458.3312

A physician licensed under this chapter may not hold himself or herself out as a board-certified specialist unless the physician has received formal recognition as a specialist from a specialty board of the American Board of Medical Specialties or other recognizing agency that has been approved by the board. However, a physician may indicate the services offered and may state that his or her practice is limited to one or more types of services when this accurately reflects the scope of practice of the physician.
