I am having issues where the providers are ordering labs and they are not being covered stating they are not medically necessary due to the diagnosis they are applying to the lab. If I look in the patient's encounter for that date, they usually only have the one diagnosis code. If I look in the charted "problems list", I can find a payable diagnosis. Am I able to consult with the provider to see if they authorize a diagnosis to be used from the problems list on the claim even though they did not chart that in that specific DOS?
