Social Security divides medical sources into two categories: “acceptable medical sources” and other health care providers who are not “acceptable medical sources”. Nurse Practitioners are in the category of other health care providers who are not “acceptable medical sources”.

In Social Security Ruling 06-03, SSA explains that it makes the distinction for three  reasons: First, SSA needs evidence from “acceptable medical sources” to establish the existence of a medically determinable impairment. Second, only “acceptable medical sources” can give SSA medical opinions.  Third, only “acceptable medical sources” can be considered treating sources whose medical opinions may be entitled to controlling weight.

This means that the medical evidence from a Nurse Practitioner can not establish your medical impairment at Step 2 of the Sequential Evaluation. You must establish your medical impairment in order to win your benefits.

This means that if all of your treatment is by a Nurse Practitioner, then you have no one who can give SSA a medical opinion about how your medical impairments restrict what you can do.

In a card game, a King beats a Jack. Social Security does not even treat a Nurse Practitioner as a Jack–more like a low card. This is not good for your case!
