Shoot, we paid about that for Canadian ER visit for stitches three years ago. We’re American, so so much for socialized healthcare, eh? No complaints on the quality of care, and TBH, here it probably would have cost $1,800 like my 45 minute local ER visit for a dislocated finger.
As for why it costs $1,800, you’re paying for a doctor, nurse(s), and supporting staff to be available 24/7 just in case you go in for stitches or a heart attack or stroke or car accident with major trauma. It’s not free to keep all those people and diagnostic and treatment equipment ready and available. The cost gets averaged out over even mundane stitches and dislocations.
