I have a question about the new 2023 requirements for an E/M visit in an office that is classified as a hospital outpatient department. I have a physician that does a shared visit with his NP. He doesn't document time spent, or if he does, he just documents total time, not individual time by both of them. In his note, he documents " The plan, assessment and decision was done by me (MD NAME). (NP Name), contributed to the history and exam". Is that sufficient to show that he performed the substantive portion of the visit, or by new guidelines, does he and the NP both need to document how much time they each spent?
