Quick take
- Ask for the cash price if your deductible isn't met - the median cash price here is $234, and it's often lower than what insurance pays before your deductible is satisfied.
- This dataset covers hospitals only - freestanding ASCs, which routinely run 30-60% cheaper for the same procedure, aren't included, so it's worth asking your doctor whether one is an option.
Providence Health, Swedish Health Services (a Providence affiliate), and UW Medicine compete in the Western Washington market. Kaiser Permanente Washington has substantial commercial market share in the Puget Sound area. Eastern Washington operates as a distinct, lower-cost market anchored by Providence and MultiCare. Washington state has active price transparency enforcement. 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.
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.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$234 |
| Deductible met - 20% coinsurance | ~$47 |
| Out-of-network provider | $515+ |
