I work for a residential BH company that also provides medical services to the residents. Because the patients are living in such a close environment, the nurses are doing vitals daily, in the evening. The next day, when they bill 99211, the vitals are dated the day before. They were told that they could use vitals from up to 24 hours previous. I don't believe this is the case. Can someone give me a definitive answer to give them as to why they need to stop doing this, or is it truly ok?
