If the patient comes to the OB/GYN office, sees a provider and confirms that she is pregnant-that visit gets billed for confirmation of the pregnancy. Then on the next visit, the patient comes in to see the nurse who does a history and lab work on the patient-is this nurse visit a billable service? Then the provider sees the patient for 2 more visit and decides to transfer the care to other office. Can the Nurse visit be billed?
