On May 18, 2016, the Department of Health and Human Services (HHS) published a final rule that will require many group health plans and employers to cover health care services provided to transgender individuals. Whether and to what extent the regulations apply to a particular plan or employer is complex. However, it is clear that HHS intends to encourage coverage of health care services for transgender individuals in the broadest manner possible. The effective date of the rule is plan years beginning on or after January 1, 2017.
