At a minimum a lot of money would be saved by standardized billing practices and costs. If Medicare pays too little then reimbursement could be adjusted. It would lead to more transparency and less bureaucracy. I think that’s how it works in Germany. There are different insurers but they operate on a set of standards. It’s nuts that in the US every insurance negotiates separately with each provider. It’s extremely inefficient and also makes it basically impossible for the patient to do any price shopping.
