I just completed a webinar on the use of ABNs. I remember nothing during the talk (and there is nothing on the handouts) regarding the use of ABNs with Chiropractic care. One of the test questions indicated that an ABN was not necessary for chiropractic. Unfortunately, I did not have the presence of mind to screen-shot the questions and I can't pull them up anymore to make sure that I read it correctly. I looked through the CMS Processing Manual Chapter 30, section 50 and nothing is explicity mentioned there. Can someone please advise? Thank you so much.
