Four families of transgender youth and two doctors have challenged an Arkansas law that would prohibit healthcare professionals from providing or even referring transgender young people for medically necessary health care. The law would also bar any state funds or insurance coverage for gender-affirming health care for transgender people under 18, and it would allow private insurers to refuse to cover gender-affirming care for people of any age. The lawsuit, filed in federal court, alleges that House Bill 1570 is a violation of the U.S. Constitution.
