When billing an E&M code along with 66821 to Medicare, is modifier 57 required?

Thanks for your question. You would append modifier 57 to an E/M service if the provider decides to perform surgery the day of the E/M service. The selection of a modifier will depend on whether the provider has decided to do the surgery at the time of the office visit or if the E/M is separately identifiable from the surgery. Other modifiers may also apply so be sure that you know the exact circumstances of the reason why the surgery was done on the same day.
