What does the term “separate procedure” mean at the end of a code?
Separate procedure is a confusing term. It means that the procedure is usually a component of a more complex service and is not reported in addition to the more complex service if performed in the same anatomic area. A typical example is enterolysis (lysis of adhesions) which is designated as a separate procedure and not reported separately at the same session as a more complex procedure, such as a colectomy, cholecystectomy, etc. If lysis of adhesions is extensive and the additional time and intensity is documented, a modifier 22 may be added to the primary code.
