There is a significant percentage of NPs, however, who never in any circumstances consult primary care physicians.
"The data revealed wide variability and inconsistency in the supervision of NPs in Florida, as detailed below. Each measure of supervision—percentage of time the physician on site,percentage of records reviewed, and percentage of required consults—ranged
from 0 to 100%, across the spectrum of NP experience. Males
worked without a physician on site more often and had fewer
record reviews than females. NPs with doctorates worked without
a physician on site more often, had fewer record reviews, and fewer
required consults than NPs without a doctorate. Twelve percent of
respondents worked with no physician on site, no record reviews,
and no required consults."
"Another wrote, “There is no supervision or collaboration. I have never met my collaborating physician and he does not
come to the clinic in which I work. He signs DME [durable medical equipment] orders for reimbursement but only after I sign
them! He never sees my patients.”

And this is Flordia, a state without independent practice for physicians. Like it or not, a significant percentage of NPs believe themselves to be be FPs and internists equals.
