I've encountered mental health professionals who have flat-out told me: I diagnose every single patient as either adjustment or borderline. They're serious enough that the insurance will pay, and vague enough that I can fit just about any kind of symptom I want in there.

And it's not just a matter of getting a reimbursement check, either. It's the legal stuff, too. Someone comes to see a physician with self-injury and he/she doesn't provide a diagnosis right away, there might be real problems down the line. Let's say that patient goes home and does something even more serious a few days later. The family hires a lawyer and goes after the MD for malpractice. The lawyers say, "He wasn't providing sufficient care...he didn't even provide a diagnosis!" (Result: Bye-bye career, bye-bye license; hello trying to pay back massive medical school student loan debt with a low-paying job.)

I'm not trying to defend the doc here. Just pointing out that the system encourages this kind of crap.
