Is there any classes I can take to learn the right way of billing for Anesthesia claims? I just started doing the billing for the Anes side of our facility and don't think something is right. We are billing for the base units, time, risk factor but only getting paid for the time due to that is what is being sent to the insurance. I'm being told we can only bill the insurance either the time or units not both. Also we are being told that we need to bill the anes code for the time and the procedure code that was done for the other is that true too? I really need a class on Anes billing.
