I think you might be able to get an E/M with -24 mod in this instance. I'm not saying for certain, because I can't review your record...
Case in point, this "displaced" fracture . . . I'm pretty sure this is going to code to a complication in ICD. Although most minor post-op complications are included in the global package, if there's more to the story (so to speak) with this displaced, subsequent fracture, I think you're justified in adding a -24. This subsequent fracture we're assuming is related to the previous surgery. That may not pan out to be true from the clinical standpoint. I'd at least consider reviewing the record and op report to determine if we had a mechanical failure of the previous pinning, a subsequent fall or overexertion or an underlying clinical picture that resulted in a return for fracture re-reduction.
I am simply suggesting to look more closely at the information (include it here if you want); I find that situations like this sometimes have features that are out of the ordinary and require some added research and perhaps coding that's "outside the box."
Hope this helps and I look forward to hearing more about this situation.
