St. Luke's Health System dominates the Boise metro and much of the state, with Saint Alphonsus (Trinity Health) as the primary competitor. Low facility density outside the Treasure Valley and Panhandle means limited price competition for most of the state's geography. Boise prices are generally moderate relative to national averages. 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
Facility classification matters as much as the hospital itself - a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. 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 | ~$419 |
| Deductible met - 20% coinsurance | ~$84 |
| Out-of-network provider | $922+ |
