1 /5 Florenda Cordova: I went in for a routine wellness check up. My insurance covers it 100 percent. My Dr. who I have seen for years never mentioned a calcium blood test. Two months later I receive a bill from hospital for the calcium blood test for which my Dr never mentioned to me. This isn’t the first time I’ve had to call billing for mistakes that were made. It’s like the fifth time they made a mistake. Especially when it comes to coding. Maybe they need to give a class to everyone there in good communication and coding. I will be looking for another Dr.
