Question: One of our providers recently left our office, so all the patients were transferred to the other providers in the practice. Because these providers are in different facilities, I am wondering if I should bill antepartum visits for all the patients, and then bill delivery and postpartum follow-up services only for those who actually deliver with us. What should I do? Iowa Subscriber Answer: If these physicians are all billing under the same Tax I.D., you bill globally no matter where the patient was actually seen. It is transfer of care within your practice, not a transfer of care from an unaffiliated practice.
