A lot of big numbers get thrown out there as the hospital bills are full "retail". By the time the hospital actually gets paid by insurance companies the true costs are much lower.

I spent a fair amount of time researching this and if you check the treatment codes against the published CMI rate book, something that is originally billed at $100 is paid at $10.

CMI is the official rates used by USA Medicare for reimbursements to medical services providers. It is a reasonable guide to what true payments are for services. You can use these rates as the low end of the scale.

One other side note. All radiation therapies use very expensive equipment. I came across but did not fully investigate the relationship between the medical equipment manufacturers, the medical facilities, and the government. It seemed like there are programs that basically influence the pricing of this equipment. Not some form of price fixing but more like supplemental forms of subsidies, grants, tax credits or breaks, to enable the financial equations to work out. If others have come across this sure would like to better understand just out of curiosity.
