We have a patient scheduled for an annual Medicare px (not a preop px) G0438 but he is having surgery with another provider prior to our physical appointment so the physical will be within the global period of the sx.

His surgery will have a global period. Will be get paid for the G0438 since I can’t put a 24 modifier on the G code? If they sign an ABN won’t the patient be responsible if Medicare denies the G0439.
I know Medicare won’t accept a mod 25 on the G code so I am assuming they won’t accept a mod 24 either.
