Fistula Duplex Ultrasound

Please note this question was answered in 2017. The coding advice may or may not be outdated.


Patient comes to our office because he is having problems getting dialyzed. Patient is evaluated by the physician and sent for ultrasound imaging. After scanning the patient's fistula, the physician reads the ultrasound and determines that the patient will require an intervention. Can we still bill code 93990 for the scan as well as the intervention if performed on the same day or week? If so, what diagnosis code should we use with the 93990? We have not been billing them due to denials.
