I posted a link earlier for the text of the new guidelines. For reference this is the portion that concerns trans care. As Dean said I am also not an attorney, but the language is pretty clear.
§ 92.206
Equal program access on the basis of sex.
A covered entity shall provide individuals equal access to its health programs or activities without discrimination on the basis of sex; and a covered entity shall treat individuals consistent with their gender identity, except that a covered entity may not deny or limit health services that are ordinarily or exclusively available to individuals of one sex, to a transgender individual based on the fact that the individual's sex assigned at birth, gender identity, or gender otherwise recorded is different from the one to which such health services are ordinarily or exclusively available.
§ 92.207
Nondiscrimination in health-related insurance and other health-related coverage.
(a) General. A covered entity shall not, in providing or administering health-related insurance or other health-related coverage, discriminate on the basis of race, color, national origin, sex, age, or disability.
(b) Discriminatory actions prohibited. A covered entity shall not, in providing or administering health-related insurance or other health-related coverage:
(3) Deny or limit coverage, deny or limit coverage of a claim, or impose additional cost sharing or other imitations or restrictions on coverage, for any health services that are ordinarily or exclusively available to individuals of one sex, to a transgender individual based on the fact that an individual's sex assigned at birth, gender identity, or gender otherwise recorded is different from the one to which such health services are ordinarily or exclusively available;
(4) Have or implement a categorical coverage exclusion or limitation for all health services related to gender transition; or
(5) Otherwise deny or limit coverage, deny or limit coverage of a claim, or impose additional cost sharing or other limitations or restrictions on coverage, for specific health services related to gender transition if such denial, limitation, or restriction results in discrimination against a transgender individual.
(c) The enumeration of specific forms of discrimination in paragraph (b) does not limit the general applicability of the prohibition in paragraph (a) of this section.
(d) Nothing in this section is intended to determine, or restrict a covered entity from determining, whether a particular health service is medically necessary or otherwise meets applicable coverage requirements in any individual case.
