That's true. But I think the system could be simpler if there were fewer, and possibly just one, entities. I work in a factory, so we live by SAP. And it's complex, typical "enterprise" software, but I don't think it's even within an order of magnitude as complex as Epic.

We want an audit trail, but most of the transactions are made within a single business entity, e.g., from the stockroom to an assembly area. We've had process improvement projects that reduced the number of SAP transactions required to make something.

So maybe the key isn't so much having a government run system, but simply reducing the number of entities. For instance a hospital doesn't have to make a claim to Medicare, if the hospital is Medicare. Also, the game of figuring out how much to bill the patient goes away.

We don't even know how many entities there are in the medical system, or how much money is going to each one. Were I inclined towards cynicism, I'd suspect that this is by design.
