How to read these prices

The negotiated price — a median of $1,108 here, usually $905–$1,617 — is the most representative figure: it is what health insurers actually pay Riverside-area hospitals for a Colonoscopy, averaged so a single outlier contract cannot distort it.

The chargemaster list price (median $4,000) is far higher. The chargemaster (list) price is the hospital's undiscounted sticker rate. Almost no one actually pays it — insurers negotiate it down and self-pay patients are usually offered the cash price — but it shows how large the discount off list can be.

No Riverside-area hospital published a genuine self-pay cash price for this procedure, so none is shown — hospitals most often publish cash prices for outpatient imaging and lab tests, less so for surgical or inpatient care.

Important — a price reference, not a bill

These figures are aggregated from hospitals' public price-transparency files — not a quote, a bill, an insurance benefit determination, or medical advice. Your actual out-of-pocket cost depends on your insurance plan (deductible, copay, coinsurance, network), the exact service and any complications, and which hospital you use. Always confirm price and coverage with the hospital and your insurer before care.
