(b) An insurer that issues to, delivers to, or renews medical professional liability insurance for a health care practitioner licensed, certified, or otherwise authorized by law to practice in the State may not take adverse action against a health care practitioner in whole or in part because the health care practitioner provides legally protected health care or makes a referral for legally protected health care.

(c) This section does not prohibit the medical professional liability insurer from taking adverse action against a health care practitioner for conduct that would otherwise constitute professional misconduct.
