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 $844, including Select Specialty Hospital - North Knoxville at $6,435, 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 $843 versus $3,638 inpatient (about 4.3× 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.
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 | ~$843 |
| Deductible met - 20% coinsurance | ~$169 |
| Out-of-network provider | $1,855+ |
