re: Psych Testing for Bariatric Surgery
I wouldn't use Z04.6 because it states it's an evaluation requested by authority. I would use Z01.818 "Encounter for other preprocedural examination" and according to the chapter guidelines, it says to also assign a code for the condition to describe the reason for surgery. Code also any findings related to the pre-op evaluation.
Hope this helps.
