There's a big difference between "checking your insurance card" and "actually logging into the Insurer's network to verify if you are paid-up on your health insurance". I don't quite know how many times a doctor's office will do the latter. Without directly logging into the insurer's database, they have no way of knowing that your insurance is paid-up. I doubt the insurer will have a field of phone operators standing by to take calls at all hours, day and night, and on weekends (including, but not limited to, emergency room visits, which might involve several different healthcare providers in the same hospital).
