The doctor of chiropractic must bring to the exercise of that person's profession a reasonable degree of care and skill, which shall include the determination of the need for chiropractic care, as defined in paragraph (2) of Code Section 43-9-1, and shall render treatment, referral to the appropriate health care provider, or both treatment and referral commensurate with that chiropractor's findings. Any failure to refer to the appropriate health care provider may subject the doctor of chiropractic to the provisions of Code Section 43-9-12. Nothing in this Code section shall be deemed to expand or limit the chiropractic scope of practice.
