We are having a problem in my office with ROS (what else?) I audit the hospital records and another girl does the office (we automatically do a pre-billing audit on any level 4 or 5, and random audits on lower levels). Anyway, on to my dilemma, someone told the person I work with that you can count listed medications for ROS (ie ritalin=neuro, insulin or synthorid=endocrine). I think these belong in past history, but I haven't been able to find any documentation that specifically addresses this. Any help or ideas would be appreciated.
