Apologies, this doesn’t answer the op’s post but you are absolutely correct.
I’ve just been in Siriraj hospital Bangkok with Pneumonia, and had to leave most of it to the Thai wife. Interpreting, paying for treatment, feeding me, staying overnight to make sure I didn’t escape. Especially letting the doctor who wanted me to move to another hospital because ‘they were very full’ know I wasn’t going anywhere.
But is that any worse than going to 3 different private hospitals , receiving 3 different diagnoses and then receiving a bill double the original quote.
12k baht to come out alive from a government hospital is good value in my book.
