Dr. Michael Kokolis, DDS Bell Dental Care Did not bill my insurance, even after I sent them proof! ,

I do not work for Kokolis and am not related either
but have been a patient of his and cannot offer any complaint inre to his expertise and experience and professionalism as a high level of dentistry and oral surgery is provided by HIM.
It is very unfortunate how the boobettes in the business office responded and did not forward your insurance claims.
Hopefully you personally followed through with YOUR insurer and received YOUR reimbursement
and possibly you realize tha Kokolis ""shares"" that office with other practicioners ? and that business office is not his and his ALONE ?

My only complaint is that I don't live closer as getting to Bayside from our location is truly a journey involving bus/train.......BUT,as a "veteran" of multiple dental procedures--we will gladly travel over there.
He is more than qualified as a DDS and unfortunately his practice had these business associates in a shared practices OFFICE-

Before my appointment I filled out an insurance form to give them the correct information.  I went into their office twice and gave them the correct insurance information in person in addition to calling them.  Instead of billing the correct insurance, they billed an old insurance company from 5 years ago that was obviously old and incorrect. 

They have still failed to correctly bill the insurance or admit their mistake.  Have you ever met someone that is 100% sure that they are absolutely right and never makes mistakes - ever.  Like someone that will argue with you for hours that the earth is flat.  That's the office manager here.   Instead of billing insurance and setting appointments they just argue with you.

Have you gone there IN PERSON to discuss the issue? Many doctors offices will still not conduct business via fax or email. They may need to make copies of your card.

Why not try driving to their office and speaking to them?
