I think spirometry can be useful - I think it helps to instill in patients how bad their disease is, it allows you to measure change with time. It does generate revenue but I think it along with EKGs are useful in the office.
I do think most docs undercode their office visits - when you see a diabetic who comes in for recheck and you do a foot exam, order labs, renew meds and address their HTN and lipids - do you charge a level 3 ? A lot of docs do and they are short changing themselves.
