Has anyone had any issues with payers "screening" for dates of service which occur just outside the global follow-up period for surgery? For example, a patient had surgery on 9-1-10 and the global follow-up for the procedure is 90 days (covering post-op care during Sept, Oct, and Nov) then the patient presents again in early December (just outside of the 90 day follow-up period) for another visit related to the surgery. The physician wants to bill for that visit since it is technically "outside" the post-op period. I get a little nervous when I see visits like this starting to get scheduled on a "routine" basis - any thoughts?
