Question pertaining billing established patient codes versus subsequent hospital codes for an outpatient stay, POS 22:
Why we would use E/M 99212-99215 with POS 22 instead of the subsequent observation care codes 99224-99226? Is there an advantage of using one set of codes over another, or specific rules for why we would use one set over the other?
Thanks in advance for any advice--
