Arizona Gov. Katie Hobbs this week vetoed a bill that would have required insurance companies to cover “detransitioning” procedures for transgender-identifying individuals who had undergone sex-change surgeries.

The Democratic governor vetoed state Senate Bill 1511 after it passed both houses of the state Legislature. The measure would have stipulated that health insurance plans that offer “coverage for gender transition procedures” may not “deny coverage for gender detransition procedures.”

It would have also required that physicians who perform gender transition procedures “must agree to provide or pay for the performance of gender detransition procedures.”

“Detransitioners,” or transgender-identified individuals who have ceased trying to make their bodies resemble those of the opposite sex, have been getting increased attention in the media in recent years. 

Oftentimes such people have been on cross-sex hormones for years, resulting in significant or irreversible changes to their bodies; in other cases, they have undergone irreversible surgeries. Extensive medical work can be required to attempt to return their bodies to normal function. 

In a “veto letter” provided to CNA by the governor’s office on Wednesday, Hobbs said the measure was “unnecessary and would create a privacy risk for patients.”

On its website, the Arizona State Senate Republican Caucus said Hobbs in her veto of the bill was “aiding doctors and insurance companies taking advantage of a vulnerable population.”

State Sen. Janae Shamp, who sponsored the bill, argued on Tuesday that doctors “must be prepared to undo the damage” of gender transition procedures “as much as possible.”

Insurance companies should also pay for such reparative procedures, she said.

“Shame on Gov. Hobbs for sending a message that the institutions tasked with protecting their health and well-being have turned their backs on them,” Shamp said on the state senate GOP’s website.

Advocates say detransitioners demonstrate why doctors and health officials should proceed cautiously with transgender procedures, especially given that many of those procedures cannot be easily reversed, if at all. 

Some formerly transgender-identified individuals, such as young adult Chloe Cole, have spoken out strongly against what they say is a too-permissive medical culture that rushes into “gender-affirming” models of care.

In the Netherlands earlier this year, a study found that nearly two-thirds of children who had wished that they belonged to the opposite sex as adolescents ultimately became comfortable with their biological sex in early adulthood.

In an interview with The New York Times last month, meanwhile, English pediatrician Hilary Cass warned there is no comprehensive evidence to support the routine prescription of transgender drugs to minors with gender dysphoria. 

The doctor earlier this year published the independent “Cass Review,” commissioned by the National Health Service in England, which prompted England and Scotland to halt the prescription of transgender drugs to minors until more research is conducted.

Shamp, the Arizona senator, this week pointed to Chloe Cole as an example of the perils of transgender medicine.

Cole was “given puberty blockers and underwent a double mastectomy” at a young age and now struggles with “the severe damage left behind,” the senator said.

“It’s unfathomable that we consider mutilating an undeveloped child’s body as ‘health care,’” Shamp said, “but what’s even more horrifying is the fact that we deny them access to care when they go on to suffer the mental and physical consequences.”
