Quick take
- Saint Thomas West Hospital is the lowest-cost option at $394 - $90 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $484, and it's often lower than what insurance pays before your deductible is satisfied.
- Ask whether this procedure can be done at a freestanding ambulatory surgical center - they're typically 30-60% cheaper than a hospital for identical care, and most aren't in this hospital-only dataset.
HCA Healthcare, headquartered in Nashville, has significant hospital presence in its home state, creating pricing patterns more aligned with for-profit hospital economics than nonprofit systems in comparable markets. Vanderbilt University Medical Center anchors the Nashville academic tier. Tennessee has not expanded Medicaid under the ACA, maintaining a high uninsured rate that influences facility pricing structures. Colonoscopy pricing is particularly sensitive to screening vs. diagnostic coding. A screening colonoscopy is typically covered at 100% under preventive care benefits, but if a polyp is removed or a finding is documented during the same visit, the claim is often re-coded as diagnostic - triggering your deductible and coinsurance. Ambulatory surgery centers perform over 70% of colonoscopies nationally and charge substantially less than hospital outpatient settings.

Why prices vary - and what it means for your coverage
A small number of hospitals (2) report prices above $2,248, including Select Specialty Hospital - Nashville at $6,374, 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 $459 versus $5,543 inpatient (about 12.1× more), 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.
None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$484 |
| Deductible met - 20% coinsurance | ~$97 |
| Out-of-network provider | $1,065+ |
