A federal judge in Texas on Wednesday ruled against a mandate requiring employers to provide health care coverage for drugs that prevent the transmission of HIV, finding it is unconstitutional and that it violates the religious rights of employers.

Why was the mandate struck down? The 2020 mandate is part of the Affordable Care Act and requires employers offer insurance plans that cover HIV-prevention pills, known as PrEP drugs. Those behind the suit argued the mandate forced them to sponsor health care coverage that they object to on religious grounds.

Why it matters: 167.5 million Americans are covered under ACA-compliant private health plans, according to a recent survey by the Urban Institute think tank. HIV/AIDS advocates say the ruling would create financial hurdles for access to drugs preventing HIV and increase HIV infections, with virus already disproportionately affecting marginalized communities.

What could happen next: The ruling could be appealed by the Department of Health and Human Services, the defendant in the case.

Breaking down the lawsuit

The 2020 lawsuit that led to the ruling originated from Texas business owners and residents, who argued that the mandate violates the Religious Freedom Restoration Act. 

The lawsuit said this mandate required religious employers to provide coverage for drugs that would “facilitate and encourage homosexual behavior, prostitution, sexual promiscuity, and intravenous drug use,” according to the suit.

HIV activists dismissed that notion. “Limiting and prohibiting a preventative medication … will not prohibit homosexual behavior or drug use or sexual activity,” Gary McCoy, an HIV positive advocate in San Francisco, told USA TODAY. “Those are things that are going to happen regardless of one’s religious beliefs.”
