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 (about 4,266), 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 CPT code on your bill matches exactly: 95810.

Insurance Before you use insurance

Call your insurance company to confirm HSHS St Elizabeth's Hospital is in-network.
Ask your insurer whether prior approval is required for CPT code 95810.
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.
