I work for a daytime hospitalist group. Another practice (not affiliated with me) runs the night shift. We are having a debate on what is billed and what is not in the following two scenarios. Any feedback is appreciated. thank you!

1)If the night person admits a patient (let us say at 3:00a.m.) then the day person takes over at 8:00 a.m. (providers are not in the same practice) and sees the patient again is this billable for both parties?

2)If a night shift person sees a patient at 3:00 am, then someone from their own practice sees the patient again at 8:00 a.m. is this billable only once?
