An insurer that takes an action which adversely affects a subject of abuse, or a related individual or entity, based on an abuse-related medical condition, abuse-related claim, abuse status, or association or relationship with a subject of abuse, pursuant to an individual or group insurance policy or health benefit plan, shall advise the applicant or the insured of the specific reasons for the action in writing. Reference to general underwriting practices or guidelines shall constitute a specific reason. The specific reason for the actions of the insurer shall be stated in writing. The actions of the health carrier or insurer, and any applicable policy provisions, shall be applied equally to all applicants or insureds with similar medical conditions or similar claim or claims history without regard to whether the condition or the claims are abuse related.
