Let the Global Period Guide Your Post-Op Coding

Question: A Medicare patient undergoes panretinal laser photocoagulation (67228) in the left eye and, three weeks later, is seen for a possible retinal tear in the right eye. How should we code the office visit, and is a modifier necessary?

Answer: The key here is recognizing that 67228 (Treatment of extensive or progressive retinopathy (eg, diabetic retinopathy), photocoagulation) has a 10-day global period. Since the office visit occurred three weeks after the laser procedure, it falls outside the global period, so you only need to report an evaluation and management (E/M) or eye exam visit code. No modifier is needed.
