This is a link to an article in the Boston Globe that raises the question about using only DSM criteria for diagnosis. It suggests that the DSM criteria are mostly based on white western thought and culture, and that the same symptom (in this article a man who describes feeling like there are bugs crawling under his skin) could be diagnosed as anxiety or schizophrenia/psychosis.

How culture shapes your mind — and your mental illness - The Boston Globe
Culture, it says, can make a huge difference in diagnosis: and it defines culture differences as being not just skin color or country of origin, but also things such as sexual orientation, age, profession, technological immersion and some other things.

Like others on these lists, my Ts have used different diagnostic codes for billing insurance and perhaps in their notes. All of them have had access to my full psych evaluation but they don't use the same codes. I think I have seen CPTSD (which I think isn't listed in DSM anymore, but it is still on my insurance billing), Alcoholism (I've been sober over 30 years), Depression, including treatment resistant and MDD, Mixed personality disorder, and DID. I think there are some others as well. I say this because mental health diagnosis is tricky, people often disagree, and symptoms overlap quite a bit in the DSM-V. And then there is that the DSM does change, disorders are eliminated and added with each revision. So I don't think that it is completely accurate.
