I worked in healthcare tech for a long time and I would say that healthcare facilities should focus on delivering healthcare. We had so much administrative overhead from dealing with this insurance bullshit that it drove up costs to staff a ton of people to deal with insurance bullshit and thus increased costs. If we had single payer it would be a single process that couldn’t possibly be more convoluted than what we have now. Sending shit to insurance clearing houses with exact ordering of diagnosis matching procedures so that they don’t get kicked back. The hospital doesn’t want you dealing with this shit either they just want the money that the insurance provider said it would pay for your treatment. It’s 90% insurance bullshit all the way down.
