We are a teaching hospital and we often have hospital medicine residents that will see/admit a patient at night and then attending will see them the next morning. We want to make sure we are billing correctly for this.

Scenario:
Patient admitted to inpatient by resident at 10:00pm on 4/1/2019.
Attending sees patient at 8:00am on 4/2/2019. Attending makes their note, attests to resident note and decides to discharge the patient. There is an H&P and a Discharge summary.

What should be billed?

Also, same scenario, but admitted to Observation.
What should be billed?

Thank you.
