HHS has estimated the rule will “likely cover almost all licensed physicians because they accept Federal financial assistance” in more than one program and in more than one setting. Nondiscrimination in Health Programs and Activities, 81 Fed. Reg. 31375, 31445 (May 18, 2016).
 The Mandate says that a hospital “will be held accountable for discrimination under Section 1557” where “a doctor is an employee of a hospital.” 81 Fed. Reg. 31384. In addition, if a doctor “works as an attending physician at a hospital,” then the doctor’s practice, as well as “the hospital may be responsible for discrimination by the doctor’s practice that occurs at the hospital.” Id. Thus, if a doctor who is simply following his or her best medical judgment is found to violate the Transgender Mandate, that doctor may not be able to get a job at any hospital because the hospital will be face serious liability and financial penalties under the new rule for employing that doctor.

 Other observers have estimated that the rule will apply “to over 133,000 (virtually all) hospitals, nursing homes, home health agencies, and similar provider facilities, about 445,000 clinical laboratories, 1,200 community health centers, 171 health-related schools, state Medicaid and CHIP programs, state public health agencies, federally facilitated and state-based marketplaces, at least 180 health insurers that market policies through the FFM and state-based marketplaces, and up to 900,000 physicians.” Timothy Jost, Implementing Health Reform: HHS Proposes Rule Implementing Anti-Discrimination ACA Provisions (Contraceptive Coverage Litigation Update), Sept. 4, 2015, http://healthaffairs.org/blog/2015/09/04/implementing-health-reform-hhs-proposes-rule-implementing-anti-discrimination-aca-provisions/.
 “Based on a thorough review of the clinical evidence available at this time,” HHS wrote, “there is not enough evidence to determine whether gender reassignment surgery improves health outcomes for Medicare beneficiaries with gender dysphoria.” HHS also noted that “There were conflicting (inconsistent) study results—of the best designed studies, some reported benefits while others reported harms.” Centers for Medicare & Medicaid Services, Proposed Decision Memo for Gender Dysphoria and Gender Reassignment Surgery (June 2, 2016), at http://www.becketfund.org/wp-content/uploads/2016/08/proposed-memo.pdf (emphasis added).

Reg. at 31455. Despite significant debate in the medical community about the medical prudence of some of these procedures, the rule states that a view of “transition-related treatment” as “experimental” is “now recognized as outdated and not based on current standards of care.” Id. at 31435.
