Why prices vary - and what it means for your coverage
A small number of hospitals (2) report prices above $2,696, including Missouri Baptist Sullivan Hospital at $3,362, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $631 versus $491 inpatient, so where a procedure happens often matters more than which hospital you pick. The biggest swing for this procedure is screening versus diagnostic coding - a polyp removed during a routine screening can recode the whole visit as diagnostic and trigger cost-sharing you weren't expecting.
What you pay out of pocket on top of this depends on your deductible, your plan's out-of-pocket maximum, and whether every provider involved is in-network - not just the facility.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$662 |
| Deductible met - 20% coinsurance | ~$132 |
| Out-of-network provider | $1,456+ |
