Dr. Monica Abreu Diaz, MD

Do not go to this doctor. She lied to me and then set up my billing for an annual preventative care visit that was to be covered by my insurance as a “medically necessary” visit, and has now billed me $800. I was very specific with her that I was only there for my Well Adult. She convinced me to do my Well Woman Exam with her since I was scheduled for it a few months later with another doctor, and she said we can just get it out of the way now. I specifically asked her will this affect my billing since this is the ONE Female Health Visit I am entitled to a year at no cost, and she said it would be fully covered by my insurance. Then her team coded it as “medically necessary” sent me a bill for $800 and won’t even get on the phone to discuss this with me. Very tired of being taken advantage of by doctors like this. Also, they won’t tell you this, but her office will charge you a $200 “facility fee” that they did not disclose.

This doctor was impatient, rude and her knowledge is poor. She has no interests in knowing her patients, unfamiliar with medications. It is a total waste of time.

I agree with the other reviews. This MD does not have a good bedside manner, is condescending, and does not listen to her patients. She also overcharged me for a short visit follow-up visit (approx $800). It was a terrible experience so needless to say I am looking for another MD.

Terrible bedside manner. Not famailiar with medications.

This was the worst doctor I've seen, they spend 20 minutes with you, they are not honest about their fees. I have insurance, and I was supposed to pay USD 25.00 co-pay, they charged me: USD 560.00 for what ? They do not want to discuss their fees with you, you can't reach them after they bill you. AETNA insurance asked me to sue the doctor and to dispute their fraudulent fees. They invent fees such as: they charge u for going to UCLA and sitting on the waiting room USD 360.00 - but her office does not tell you that. This doc is a fraud! Do not go there.
