The reason it's going to providers is because US healthcare is extraordinarily inefficient. Providers spend too much time doing, well, everything. From admin, to medical records, to documentation. Very little of their time goes to actual, direct care and decisions around care. You can talk to a doctor about this if you want, they'll all tell you the same thing.

Even surgeons. Ask a surgeon how much time they spend in the OR. It's less than you think.

It's going to the administration overhead. If you have to document everything and argue for every medical procedure and deal with 20+ different processes for filing claims then it takes time. And, as a provider, you have to pay someone to spend that time if you want to get paid.

It doesn't help that our healthcare billing systems are so outdated and broken. I once had a doctor visit denied with the reason code that it should charge the other insurance (for people on multiple plans). I was only on one plan, but my wife was on two. The doctor and I went through all the paperwork - my name was right, my birthday was right, my policy number was right and when I got notice of the rejection it had my name on it. Eventually we traced it to an error - not in my insurance company, not in the company that handles claims in this areas for my insurance, but instead in some middle-man company that was responsible for transferring claims between the two. Nevermind that all three companies claimed to be BlueCross BlueShield. This took over a year to resolve.

> Today, many of those practices have been bought up by large corporations, including hospitals, private-equity firms and even health-insurance companies. It’s a shift that not only has changed how money moves through the health care system, but may also be helping some insurers boost their profits, according to new research published in Health Affairs.

> A study from researchers at Brown University’s Center for Advancing Health Policy through Research and the University of California Berkeley found that UnitedHealthcare, the nation’s largest health insurer, pays doctors who work for its own physician network, Optum, more than it pays independent practices for the same care.
