Insurance Switch Question...Please Help!?

[D.Dub622]

My employer is in the middle of an insurance provider switch. They are going from a company called Physician's Care to BCN HMO. My question is...I'm pregnant and have frequent doctor's appointments, including one very important appointment in a few days that includes an ultrasound. We don't have our insurance cards yet, nor are they giving us our group number yet. For some reason, this switch over is taking weeks...and likely another 2 weeks from now.

I still want to go to my appointments, as I really need and want to. Is it normal to tell the doctor's office/hospital that my employer is in between insurances currently but it should be resolved in a week or two and give them the name of the rep and my soc. sec. number?? I shouldn't have to re-schedule all my appointments b/c they can't seem to get this situation handled in a timely manner, should I??

Soooo...frustrated!! Help!! Thanks!!
