Our PT works with geriatric patients. His time with the patient looks like this:
97035 Ultrasounds are usually 5-6 minutes (not 8 min)
97110 15 min
97140 15 min.
1) May I bill Ultrasound for less than 1 unit (.33)? Or
2) May I bill Ultrasound for 1 unit due to the fact that the other two (2) codes are way over 8 min? Or
3) Are all Ultrasounds non-billable at this clinic?
All of his notes state Ultrasound for 5' or 6'
