My care was wonderful. My issue is with coding and billing just like the lady who reviewed beneath me. I had an emergency surgery and coding thinks this is classified under maternity care because the emergency was with my fallopian tubes. No baby, no fetus, no maternity. It was a cyst. Insurance won't cover because I don't have maternity insurance. They've reviewed it and coding still thinks it's maternity. I don't know what to do anymore. They won't let me speak to anyone over at coding. I've got a pretty $16000 bill to pay all by myself.
