Wiki post op complications

[solocoder]

Per CPT global guidelines: Complications, exacerbations, recurrence, or the presence of other disease or injuries requiring additional services should be separately reported. [emphasis added]

So for non-medicare patients who have complications requiring an in-office procedure within the global period, what modifier would be correct to use on the procedure?
It is related, it is unplanned, but no return to the OR/procedure room.

Any thoughts? Please?
