Self-Pay How to get the cash price

Tell the billing desk you want to be billed as self-pay — not through insurance — before your visit.
Ask for the cash / prompt-pay discount in writing, with the exact price, before you agree to anything.
Get it in writing that they won’t also bill your insurance, so the cash price is what you owe.
Check the MS-DRG code on your bill matches exactly: 470.

Insurance Before you use insurance

Call your insurance company to confirm Tristar Centennial Medical Center is in-network.
Ask your insurer whether prior approval is required for MS-DRG code 470.
Confirm the doctor or provider is in-network too — not just the hospital building.
Check your Explanation of Benefits against the hospital’s final itemized bill.
