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

A small number of hospitals (1) report prices above $2,648, including BOUNDARY COMMUNITY HOSPITAL at $1,949, 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 $644 versus $946 inpatient (about 1.5× 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.

On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.

Freestanding ambulatory surgery and imaging centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.

Why is a colonoscopy so much cheaper at some Idaho hospitals?

Prices vary up to 294.5× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Idaho, the median cash (self-pay) price is $688 versus a median negotiated rate of $153 - about 4.5× higher. Asking for the cash price or your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a colonoscopy in Idaho?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.
