Are you or are you NOT suppose to use what the reading physician finds AFTER the sleep study as the PRIMARY diagnosis for a sleep study? I went to a seminar Nov 2011 and was told that you NEVER use the interpretation as the primary diagnosis but should use the REASON for the study as the primary diagnosis. I know what CPT says for outpatient diagnosis selection but the guy doing the seminar indicated that these sleep studies are different in diagnosis selection! Can someone PLEASE help!?
