Colonoscopy Cost in California Without Insurance (2025)
California has the nation's most competitive outpatient surgery market — dozens of independently owned ambulatory surgery centers (ASCs) compete on price across the state's major metro areas. For self-pay colonoscopy patients, this means all-in prices as low as $900–$1,200 at ASCs in Los Angeles, San Diego, San Francisco, and Sacramento. Hospital outpatient departments charge 3–5x more for the same procedure.
What does a colonoscopy cost in California?
Cash pay colonoscopy prices in California by facility type:
• Ambulatory Surgery Center (ASC): $900 – $2,000 all-inclusive • Hospital Outpatient Department: $2,500 – $5,500
The 'all-inclusive' ASC price bundles the facility fee, gastroenterologist fee, and anesthesia. Hospital bills often come separately from multiple providers and include facility fees that can exceed $2,000 alone.
In Los Angeles and the Bay Area, competition among ASCs has driven cash pay prices lower than most other major markets. In rural California, prices may be higher due to less competition.
California's price transparency advantage
California's hospital price transparency law (SB 1056) requires hospitals to publish their standard charges for all services. Combined with the federal CMS price transparency rule, California patients can now compare exact cash pay prices before scheduling.
Prevu Med aggregates these published prices so you can see side-by-side comparisons from California facilities near you — no phone calls required.
Tips for getting the best price in California
1. Compare ASC prices in your city on Prevu Med before calling anywhere.
2. Ask specifically for the 'self-pay colonoscopy package' — most ASCs offer a bundled rate for cash-pay patients.
3. Consider traveling 15–30 miles for significant savings. In the Bay Area, prices at ASCs in the suburbs are often $300–$500 lower than in San Francisco proper.
4. Medi-Cal covers screening colonoscopies for eligible low-income Californians. If you might qualify, check eligibility at coveredca.com before paying out of pocket.
