California has the most competitive commercial hospital market in the country, with aggressive multi-system competition in every major metro driving meaningful price variation. Kaiser Permanente's integrated payer-provider model covers roughly 40% of the insured population in the state - if you're Kaiser-enrolled, the prices here largely don't apply. California's robust price transparency enforcement under SB 1204 means the data here is more complete than in most states. 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 $980, including LOS ROBLES HOSPITAL AND MEDICAL CENTER at $1,183, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. 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 | ~$246 |
| Deductible met - 20% coinsurance | ~$49 |
| Out-of-network provider | $541+ |
