    Im a psychologist here in LA. Most of my sessions are 55-1 hour. Medicare I was told will likely audit if we bill 90837 vs 45 minute code is that true in your experience? so even though I have only 4 medicare patients I dont bill 90837 even though the sessions suit that code because I dont want the hassle of getting audited. Please advise, would be much appreciated.

      That is not true based on our experience. Best to always bill the most accurate CPT code and diagnosis no matter what as that is what prevents fraudulent billing and will help you IF there were to ever be an audit. But no, we’ve never had any audit issues with 90837.
