I had a doc ask me yesterday about this scenario--

Pt has glaucoma and is taking meds to control it. Pt needs cataract surgery so we stop that med as it can crease the chances of complications after cataract surgery. Then after surgery during the 90 day global period everything looks fine so we start up the medication again. At that visit the docs want to charge an office call with the modifier 24 as it's a different diagnosis-glaucoma. I said the starting and stopping of the med was related to the cataract surgery and during the global period so I thought we would not be able to charge an office visit.

As the doc's disagree, I wanted further insight from other coders.
Thanks in advance for your opinion.
