Wiki Aetna denying two specialties to bundling

[treinemer]

I have an inpatient that Aetna is denying the 99223 that the Hospitalist charged for the admit because the patient had surgery that morning by a general surgeon (43830). They paid the 43830 but are denying the 99223 unless it has a modifier on it.

I am confused because they are different specialties 99223 shouldn't need a modifier but am being told by my follow up person that Aetna has it's own edits. HELP
