IMHO -58 modifier isn't appropriate for the initial treatment of a surgical complication; this modifier is for subsequent, staged (preplanned), more extensive types of procedures. Think of it this way: First this, then that.
In 2008 CPT take a look at modifier -79; the wording has changed to not only include "return to OR" but also "or treatment room" (I'm paraphrasing because I don't have a CPT book with me at this moment).
I would check this to see if it's more appropriate to use for your case.
Example Scenario: if the initial treatment of the complication included the I&D for abscess, and then the patient was told to return in 3 days for another I&D, the procedure for the 2nd I&D is "preplanned" and the -58 modifier can go on the 2nd I&D procedure.
