NA is a very useful abbreviation and I for one would not think poorly if a specialist used that next to the PFT. At least it leads me to believe the specialist knows what PFTs are
Even as a primary care,I may not always be the doc doing the Pap or the rectal or the prostate exam. Here is where I use shorkeys such as NEGYN (not examined, performed by the gynecologist). I have acknowledged that I know what a Pap is and that certain people should have them done and who the patient or I have declared should be responsible for doing it. As a specialist, a simple DPCP (deferred to the primary care physician) would be fine. If an orthopedist sends me a note that says "The neck was without thyromegaly or lymphadenpathy" then I am going to have a lot of trouble taking any part of their note seriously.
