Should I say something to my dentist?

I went to the dentist for a check up. I’ve changed insurance since the last time I was there, so I gave them the new card.
After a minute one of the receptionists comes out, holding the card out to me as if to give it back, and said, “Do you have a dental card? This one doesn’t say anything about dental visits.”
I just kind of looked at her for a second, then took the card, called the 800 number on the back of the card, went through all the hoops and all the prompts until I got to a customer service rep.
At that point I passed the phone back through the window to the receptionist so she could talk to the lady, to find out they don’t send out a separate card, and here’s how to file.
It wasn’t an earth shattering situation but….isn’t kind of HER job to track down this information when there are questions like this?
And surely I’m not the only patient they have with CIGNA health care?
