I don't qualify for Medi-Cal (California) and I am pregnant...?

I was approved for the "presumptive eligibility" for Medi-Cal when I went to the doctor at 6 weeks into my pregnancy. Then I went to the the social services office to apply for Medi-Cal for my whole pregnancy and they determined a few weeks later after looking at my paycheck stubs that I am not eligible. I make a little too much money. So, my question is, are they going to bill me for that one doctor visit I had at 6 weeks that was covered under the presumptive eligibility? Thank you .
