Can any one help me out.

1) Scenario 1: A patient was seen at Office in the morning for Asthma and discharged while returning home got injured and presents to the same ER for injury to the leg and was seen by the same physician. Can the physician bill for two OV on the same day? Is the same applicable for inpatient care and for consultation also?

2) Scenario 2: A patient was seen at Office in the morning for Asthma and discharged. The patient returned home and the asthma got exacerbated and presents to the same Office for for further evaluation and was seen by the same physician. Can the physician bill for two OV? Is the same applicable for inpatient care and for consultation also?
