WASHINGTON — The Biden administration said Monday that it intends to enshrine anti-discrimination protections for gay and transgender people in the Affordable Care Act — a proposal that would officially reverse a policy adopted by the Department of Health and Human Services under former President Donald J.

Trump. The Trump rule, finalized in 2020, erased Obama-era protections for transgender patients. Last year, the Biden administration took a preliminary step toward restoring them, by announcing that H.H.S.

would draft a rule prohibiting discrimination on the basis of sexual orientation and gender identity by hospitals and other health care providers that receive federal funding.
