Yeah, but the problem is, if tests / labs show the precursor indicators for those diseases, and you have a family history, they’ll still deny until you actually have the something like a heart attack or stroke.
GLP-1s are the hot new thing, but it’s pretty common for insurance companies to deny expensive preventative care, even after all other avenues have been thoroughly explored.

We just changed insurance and were able to get through with one provider that valued preventative care more, but our new insurance company is a complete pain in the ass. And the person in my family dealing with the insurance company actually works for the company and knows all the ins and outs.
They even give their own employees crap policies.
