Self-Pay How to get the cash price

Ask for the cash / prompt-pay discount in writing, with the exact price (about 462), 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: 72131.
