I finally got AC tech support's attention. Dan, one of their techs uploaded my practice data 3 days ago. They admitted that their is a bug. It affected a few other groups too. It seems that there will be problem if you have modified the description of the code in the past. We changed 327.23 "Obstructive Sleep Apnea" to 327.23 "OSA-Obstructive Sleep Apnea" years ago under the Access version. This can help the docs to pull this code easily. Just like "COPD-Chronic Obstructive Bronchitis w/o exacerbation". With the updates, bugs came up. Hopefully they can fix it in the coming AC V5.
The reason I like AC is that they are open to suggestions and they admit that they could have bugs and need feed back and improvements. The first few times we call for help, the answers are totally irresponsible, beating around the brush, wasting time. I do appreciate all your help and suggestions. Will wait for V5.
