Far from the first time someone has explored this and I want to be clear I personally haven't vetted this article. But it does contain interesting statements from a nurse and appears to source its facts.

Right-wing source as so often has to be as Left Wing mainstream seems not to cover trans lobby critically. Aside from statements about how internal critics at hospitals are pressured to be silent. A few quotes which stood out to me:
"...a Wisconsin district court ruled that the state’s Medicaid agency had to cover "gender-conforming surgery." The court’s reasoning was the same as Human Rights Campaign’s: To cover mastectomies for breast cancer but not gender dysphoria, it said, "discriminates on the basis of diagnosis."
"Lawyers will always advise hospitals to take the most legally defensive course of action," Sapir said. "In practice, that means deferring to the network of civil rights groups that will sue them."
"Last year, for example, the Human Rights Campaign deducted points from two Texas hospitals, UT Southwestern Medical Center and Children’s Health in Dallas, because they stopped using puberty blockers to treat gender dysphoria but continued to use them to treat precocious puberty—the blockers’ original purpose. That "amounts to discrimination against transgender youth," the Human Rights Campaign argued in a press release."
It's a fairly long article and actually quite good, imo. Big photo of Trump in a sidebar may put some people off.
