Hello, We sometimes use just CRNA’s with a QZ for surgeries. One will work a certain amount of time then another CRNA QZ will take over for them. We then bill the two different CRNA and their time. Insurance companies will sometimes require records documenting both CRNA’s but is there anything additional that needs done to get both paid? One insurance company is telling us that an additional modifier is required, we disagree. I would love some advise on anything we may be missing. Thank you
