That has at least one fairly simple explanation: those centers only take lower acuity patients. If you're complex with a history of complications, it'll be "we'll do this one at an actual hospital".
(This is frequently the case for my wife.)
They may also not take Medicaid patients; my state publishes lists of ones that actually do because of this. https://www.health.ny.gov/health_care/medicaid/quality/surge...
Right, I know that surgical centers operate with a variety of important limitations (surgical centers as they exist now are not an answer to the US health spending problem, which I preemptive agree is very real). I'm just saying that they're evidence of an at least semi-functioning market; they couldn't exist without that (who would send pts to them otherwise?).
