This is a bigger problem because when patients get care now, they can get many bills sent to them for essentially one patient encounter or admission or whatever. You can get a bill from the hospital, the radiology group, the cardiology group, the lab, etc. Patients often have to figure out how much they really owe, which bills to pay, etc. It isn't as straightforward as it sounds. There will likely be a push over the next for years for a single bill coming out of hospital encounters. This will likely mean that everyone owed money will have to compromise when the whole bill is not paid. Who gets left out? It's kind of a quagmire.
Example: my kid had to get an xray and a CBC for a limp he had. I got bills from the pediatrician, the lab, the hospital (for the xray) and the radiologist for interpreting the image. Because we have a deductible like most people do now that hadn't been met yet.
