I have seen a FEW minor insurance plans that have allowed a provider to bill more than 1 90801, but in the cases I saw they could only bill 2 in a row. Not sure what the logic was and it was only one plan. Dr told me that they allow him 2 sessions to do initial evaluation to determine dx. Actually I can see with some very involved cases where that can be needed. Hard to get to the bottom of 30 yrs of depression, etc, bad childhood, and more in one session. Can be overwhelming for the patient. But most carriers do not allow it. Linda's info is correct. I just wanted to mention that I have seen it allowed but on a very limited basis. It may have been something that the provider negotiated in their contract??
