How practices handle this today, in their own words
Verbatim from recorded calls to dental offices. Names withheld.
We call the insurance, or I go on their website and do it. Yeah, we manually do it.
We have a third party insurance verification team that does it for us. I’m not too sure, maybe like seven, ten minutes.
Our system does it, and the ones that are not set up for electronic, we do ourselves.
How getting set up works
Book a discovery call
A 15-minute call with our team: we show you a check and size your plan. Then you sign up from the link we send you: create the account, sign the agreement, and put a card on file.
