Most hospitals send a summary bill (for example pharmacy: $5,000) hoping you’ll panic and just pay it. These are usually full of errors or huge markups. Before you pay anything, call the billing department and ask for an itemized bill with CPT codes. This will not only force a human to review it, but it also gives you the ability to spot BS. I tried this last year and the bill dropped by about 30% literally just because I asked, so don’t let them rip you off.
We live in Denmark. My wife lost her job at a senior home due to stress. 3 years later, breast cancer diagnosis followed by a quick operation. Shes waiting for the radiation sessions now. In the US, we would probably have gone bankrupt. Sorry for you guys.
