Uninsured and self-pay patients can frequently access diagnostic colonoscopy at a lower cost than insured rates. Many hospitals in Washington offer cash discounts of 30–70% off the standard chargemaster rate.

In Washington, the average cash price for diagnostic colonoscopy is $1,099, which is 47% lower than the average list price of $2,076. This discount is typical of what self-pay patients can expect when asking for the hospital's uninsured rate.

For insured patients, the negotiated rate between your plan and the hospital determines your cost share. If you haven't met your deductible, you may pay more than the cash price. It's worth asking the hospital whether their self-pay rate is lower than what your insurance would charge — some patients save money by not filing a claim.
