My cardiologists have recently started billing the tobacco cessation counseling codes 99406 and 99407. I know when billing these codes with a separate E&M, we need the 25 modifier on the E&M. Sometimes, an EKG 93000 is also done. My question is, do we need a 59 modifier on the EKG when billing all three codes together? I've found one online source that specifically says we do need the 59 in this scenario, but nothing else addressing billing the three services on the same date by the same doctor. Any help with this would be appreciated!
