We have some patients that come in with an abscess and extensive cellulitis or other complicating factor (e.g. location near a joint) . In addition to an incision and drainage procedure they require care in the global period which I believe is not part of the routine postoperative care following incision and drainage ( which typically would include packing changes, wound check, culture followup) in the 10-day global period. These complex patients require IV antibiotic therapy (daptomycin) which also includes monitoring for toxicity of the drug (lab tests every 3 days). I believe that (presuming the documentation supports the above services) that it would be appropriate to code a separate E&M. Do you agree? Would it be correct to use a -24 modifier on the E&M service?
