Prohibits health care professionals from providing gender-affirming health care services to persons under 21 years of age.

New Jersey's A-1847 prohibits licensed health care professionals (including doctors, nurses, and therapists) from providing gender-affirming medical care - such as hormone therapy or surgery - to individuals under 21 years old. The bill defines these services as medical, surgical, or therapeutic care related to gender identity, excluding mental health or psychiatric services. Violations would result in professional disciplinary action under existing laws. The law takes immediate effect and applies to all covered health care providers statewide.
