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 767), 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 HCPCS code on your bill matches exactly: 90371.

Insurance Before you use insurance
