I think you're overthinking this whole thing. 96127 is for brief, self-scoring assessments completed by the patient. I called this a "trained monkey test" versus a "licensed clinician test". What I mean by that is, any trained monkey can score the test. You just add up the columns, there is no decision-making, no interpretation, nothing like that. Think of a urine pregnancy test which is a stick - there's a line, it's positive; no line, it's negative. Examples of 96127 are the Beck Depression Inventory, the PHQ.
A licensed clinician (or non-monkey test) is something like a pap smear, where someone is looking thru a microscope, identifying and counting abnormal cells, or an xray or other imaging where they are interpreting what they see.
