Did my dentist scam me?

Hello,

Quick question.

So my mom (47f and we are located in CA) got a root canal and a crown earlier in the year. My mom has medi-cal Molina insurance.

So the dentist told us that that insurance didn’t pay for anything and so I payed $250 for the crown and $1600 monthly on a credit card they gave me.

My mom had gone back for something and one of the ladies slipped up telling her they’re waiting for the insurance authorization and my mom was like wdym since I’m gonna pay and you said they don’t cover anything? And then the last time they called her and said they’re still waiting on authorization from insurance and my mom was like again I am paying so waiting for what? And the girl got kind of nervous and said oh okay let me re check.

So my mom called our insurance company and turns out the dentist never submitted anything to them to see if We would qualify. The insurance said that they cover 100% of everything so they helped us start a claim.

The name of the form is “medi-cal claim form for reimbursement”. Has anyone ever filled that out or gone through that process or can say anything that might relate to this? It also asks for a payee data record but we are not sure what that is. Anything would help please.
