How much does Colonoscopy cost in Seattle?

Median insurer-negotiated rates range from $1,281 at St. Anthony Hospital (Gig Harbor) to $4,954 at MultiCare Mary Bridge Children's Hospital, based on the hospitals' own federally mandated price files.

Is it cheaper to pay cash than use insurance?

Sometimes. Several hospitals publish discounted cash prices below the rates insurers negotiate. If you haven't met your deductible, ask for the self-pay price.

Why do prices differ so much between hospitals?

Each hospital negotiates rates separately with each insurer, and hospitals in the same health system usually share one contract. The same procedure with the same insurer can cost several times more across town.
