Hello everybody!

I have health insurance with CSS, model callmed. I've seen that CSS now offers multimed model, which supposedly is a combination of callmed and familiy doctor; the multimed model is cheaper than callmed even though seems to offer callmed services plus family doctor.
I've tried to ask CSS if there is any drawback in choosing multimed (as it seems strange to me that offers more thing than callmed but it's cheaper) but they just said "multimed is a combination of callmed and family doctor models"; so I would like to know if anybody knows more or has personal experience regarding CSS multimed.

Many thanks!
