2 (intro.); and to create 146.36, 441.07 (1j), 448.02 (3m) and 448.978 (1m) of the
3 statutes; relating to: prohibiting gender transition medical intervention for
4 individuals under 18 years of age.
Analysis by the Legislative Reference Bureau
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
 2023 - 2024 Legislature -2- LRB-0191/1

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.
