What it would have done

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

This bill prohibits health care providers from engaging in, causing the engagement in, or making referrals for, certain medical intervention practices upon an individual under 18 years of age if done for the purpose of changing the minor’s body to correspond to a sex that is discordant with the minor’s biological sex. The prohibitions under the bill do not apply to any of the following: 1) a health care provider providing a service in accordance with a good faith medical decision of a parent or guardian of a minor born with a medically verifiable genetic disorder of sex development; 2) the treatment of any infection, injury, disease, or disorder that has been caused by or exacerbated by the performance of a gender transition medical procedure, whether or not that procedure was performed in accordance with state and federal law; or 3) any procedure undertaken because the minor suffers from a physical disorder, physical injury, or physical illness that would, as certified by a physician, place the minor in imminent danger of death or impairment of a major bodily function unless surgery is performed.

Under the bill, the Board of Nursing, the Medical Examining Board, and the Physician Assistant Affiliated Credentialing Board are required to investigate any allegation that any person licensed or certified by the respective boards has violated any of the prohibitions on engaging in, causing the engagement in, or making certain referrals for the medical intervention practices described in the bill. Upon a finding by the Board of Nursing, the Medical Examining Board, or the Physician Assistant Affiliated Credentialing Board that the holder of a license or certificate has violated any of these prohibitions, the bill requires the Board of Nursing, the Medical Examining Board, or the Physician Affiliated Credentialing Board to revoke that person’s license or certificate.
