19301 Follow ups/global rules

Best answers
One of my surgeons wants to charge a follow up visit when having a "cancer discussion" and reviewing a current MRI and deciding to return to surgery for Axillary node Disection - is the office visit chargable - or is it still part of global - example - DOS --6/8/9 19301 w/global of 90 - pt returns on 6/11/9 for results and is scheduled for MRI - this is part of global - correct? (suregeon wants to charge f/u visit) - pt returns on 7/7/9 to review MRI result and is scheduled for Axillary node disection - again surgeon wants to charge f/u visit - I say this is all part of global - HELP!!!!!
