Dr. Michael Dao

Basically Have No Accountability & Not Professional

This is a medical clinic that have multiple doctors. This negative review is based solely on Dr. Anh Thu and their billing department lead, Jessica Nguyen.

As a patient, you would hope that your primary care physician care enough about your health at a minimum. Instead, Dr. Anh Thu treated my mom as her experiment by prescribing Cologuard, new method for colorectal cancer screening (from Exact Sciences).

Once result came in, the Dr./office didn’t bother to contact my mom to provide her the result and/or request her to come in for a follow-up appt.

On top of the poor follow-up skills with patient(s), insurance company does not cover this method stating that this is considered “experimental” compare to the traditional method (which is covered by all ins. co./Medicare/Medi-Cal, etc).

Besides this, the Dr. billing dept. didn’t bother checking with insurance co. on behalf of their patient in advance to see if this is even cover (probably getting some kind of kick-back from vendor…assuming).

Unfortunately for my mom, she have PPO so no authorization is needed (wish she have HMO in this case).

What make me furious is that I had to contact the office multiple times on different occasion (at least 4x…e.g. in-person & calling) to get assistance and yet I barely had any help.

My only request from Dr. Anh Thu was for her to provide me a “Letter of Medical Necessity” (required by my mom ins.) to explain why she/Dr. chosen this method rather than the traditional one to submit it to my ins. in the process of appealing.

The office was quite unhelpful and told me that the Dr. is on vacation (I was like…you don’t have a back-up Dr. in her place while she’s out or what???) so I had to put everything on hold & wait until she get back from her vacation which is about 2 wks (ridiculous).

I then thought miracle has happened since I was able to get some assistance with their billing dept lead, Jessica Nguyen (I think that’s her last name).

She was nice enough to fax over a one time request for insurance to rethink of their decision (didn’t explain anything except asking them to rethink and pay this bill).

She never gave me a “Letter of Medical Necessity” which is the one thing I’ve requested from her multiple times & it is the main thing that’s needed by the ins. co.

I then tried to call her multiple times and leaving voicemail on her office line but she never pick up or response back.

Overall, I felt this office and Jessica/billing dept was unprofessional.

All they have to do is response to me and tell me there’s nothing they can do but yet they chosen avoidance instead.

Throughout this ordeal, the Dr. office keep blaming the vendor saying that they’re the one who lied to the office about having this procedure be covered by insurance co.

I felt that the Dr. office were not accountable for their wrong action and I’m hoping that others will learn from my experience and never to go to this unprofessional medical office/clinic (or their affiliated offices since management is questionable) as there are many other physicians/healthcare practitioners that are better and care about their patients more.

Unfortunately for my mom, she’s now stuck with an unnecessary bill due to the Dr/billing dept. not doing their due-diligence.

Once again, I’m hoping others will rethink before signing up/going to this office since they basically have no accountability & not professional what so ever.

  1. They sent my mother with low income to Labcorp for blood test without checking if her insurance will cover or not.

    ZERO Star rating – By far the WORST medical experience I’ve ever had. The high amount of error and lack of professionalism from both the physicians and staffs. They sent my mother with low income to Labcorp for blood test without checking if her insurance will cover or not.

    Then she got slapped with a medical bill for over $1000. When we went there to ask them to clear with Labcorp regarding to our medical bill. They refused to help us, they were rude and mean. The medical board should review into their unlawful and ethical practices.

    I have no respect for these dr.s and advise anyone that steps foot in this place to RUN AWAY, ask your insurance to get you an actual medical practice. Zero star rating!
