Edits for cpt code 76770 & 76775 of renal ultrasound with doppler

As I have told you the Ultrasound is a part of duplex exam. Hence, when we are coding a duplex exam cpt code with ultrasound, we should use a modifier so that both procedure should get paid. Since, ultrasound is included in duplex exam we will have CCI edits when we code them together. Hence, when we are coding renal ultrasound with duplex, the cpt code with ultrasound should be appended with 59 modifier. The 59 modifier will make ultrasound a distinct procedure from duplex exam and complete separate procedure. So, next time if you are coding 93975/93976 and 76770/76775 together, do check the CCI edits and use a 59 modifier with appropriate cpt.
