Ask Dr. Z

A question has come up from a Radiology bill. The radiologist coded 76870 and 93976, the hospital coded just 76870. My question is what documentation is needed to be able to code the 93976? An example of the documentation, "Color and duplex doppler interrogation of both testicles confirms normal testicular vascular flow bilaterally" or "Color Doppler and spectral waveform analysis demonstrates normal arterial waveforms within both testicles". My understanding was that "inflow and outflow" needs to be included or "Arterial/Venous flow" must be documented. I want to code correctly but not to over code.
