During my visit (to the ER), I received three bags of IV fluids, two rounds of blood tests, and one X-ray -- and 6 weeks later, an array of medical charges approaching $10,000. Despite my insurance company negotiating it down to $4,800, the onus of the entire amount still fell on me due to my high-deductible health plan (HDHP).
When I contested the seemingly exorbitant charges (even after they had been negotiated down) with the health system, I was met with the response that their fees were legally sound and consistent with charges for all their patients.

Although this person has an HDHP this scenario could apply to anyone with a plan that has a large OOP comprised of deductible, copay, coinsurance.
Apparently the light bulb didn't come on until HIS ox was being gored.
