Dislaimer: Codes in this article are examples only.  For mental health professionals, the 99355 is almost always billed with 90837 or 90847. In addition, the first amount of extra time must be billed with 99354. Only if both 90837/90847 and 99354 have been appropriately billed can the extra time be billed with 99355.  99355 cannot be billed without 99354. Until the sessions reach an appropriate length you cannot bill 99355. Make sure to document the time spent to ensure you can bill 99355.
