How to use this estimate
- Start from the tier that matches your situation rather than the average. Screening, ambulatory surgery center is the floor at $2,270; Screening, hospital outpatient sits at $4,410.
- Ask the provider for an itemized cash-pay quote that names each of the 4 mandatory add-ons above. If a quote is far below $1,510, it almost certainly excludes one of them.
- Compare at least two providers in California. The $1,510–$6,970 range on this page exists because the same procedure is priced very differently by hospital-owned and independent practices.
