I work for a nephrologist and was told by my billing department supervisor we can't bill 90945 for CAPD...we have been paid on this before and am unable to find where it says we can not bill for this. I have e-mail's in to several of our provider reps to see what they say, can't find anything on Medicare, I e-mailed RPA asking if we could (no answer yet), my supervisor, boss and office manager don't know much about coding so I just want to make sure I have a solid answer. Any help is greatly appreciated!
