Labcorp

Is it the patient’s responsibility to ensure Labcorp has the correct address? Apparently so. My family go to the doctors for routine physical or other medical visits every year and we do not keep track which lab the doctor uses nor it is our duty to do so. Two years ago, during one of the visits, blood was drawn in the doctor office from one of the family members. We gave in to «having peace of mind» and four of us got poked at least once a year. At the time, we had no idea Labcorp was involved and worse they had our address wrong.
So when a collection letter showed up two years later, it was up to me, the customer, to trace back the healthcare inter-​web and to find out where that bill originated from. The process was quite exhausting, I gave up in the end and just paid. With patience, the insurance, the doctors office, and the doctors’ billing departments, could be reached, although not much help from them. Labcorp, however, is beyond reachable. I tried and tried, the longest time I waited was 26 minutes. I finally realized they didn’t intend for me to ever reaching them, so I went on their website and checked my info on their system. Wouldn’t you know it, they had my address completely wrong. IT IS POSSIBLE FOR THEM TO CHECK WITH THE DOCTOR’S OFFICE where they got our address at the first place. Are they too big to check with the doctor or the insurance company if they have the wrong address?
A simple doctor visit generated such a tail/​tale, it should have been the end of it after we paid bills from the doctor and whatnot. What if someone who does not use Internet or computer savvy and can’t correct the personal info online? Would he or she be able to ever correct the billing address mistake in the system? I drop my review here since this is Labcorp’s headquarter according to their website.
