OK so for the 90801, you would take the "par" amount of $164.03 and multiply it by 130% which is $213.24 and by 150% which is $246.05. Then you would set (or suggest) a fee for 90801of $225.00 or something else in between $213.24 and $246.05. See how it's done?
You can be a Medicare provider but be non par. They pay 5% less but you can charge up to the limiting fee. Problem is money goes to the patients. Unless you accept assignment but then you have to accept the non par amount and can't charge the limiting fee, so basically you are non par, agreeing to be par but at 5% less than what the real par provider are.
