I had been charged more than a years for services which I never had.
For example, for INR test I was charged Lab etc. and lab test while there I never visited or seen labs (LOL). They were using hand-held device to get atypical result to do test twice a month to collect more money from insurance. Whole thing is opposite in Mass general hospital, less charges, flexible time and accurate blood test results to save time and money.
I am still paying overcharged amount by they used incorrect code. So Be Aware.
