Advanced Medical Analysis makes plenty of billing mistakes. They will incorrectly bill your insurance company, and of course the claim will be denied. They will than bill you for the full balance. Any attempts to have them correct their mistakes will be ignored! Don't have any work done by AMA!!
You don't have to worry about that. They are bankrupt and out of business. They have closed all draw stations.
They constantly did this when I was working there. All insurance payments were stopped as they were being investigated for fraud. They ended up laying off a ton of people because of all the money NOT coming in.
Beware they are now doing business under the name of MDLab http://mdlaboratories.net/, still in Monrovia down the street from AMA. Still using the same testing and billing practices.
