My provider had a patient come in at 39 weeks stating she wanted to transfer care so pre-natal record was started. He only saw her for 1 visit and the Doctor on call delivered her 3 days later who is also a part of our group. The proveder the patient is not in our group so I called to see if she had officially transferred her care. They only had a note saying patient cancelled her appointment because it wasn't a convient time. There is an on call arrangement between the providers. Because she never officially transferred care from her primary OB to us would I just bill for the one visit and her first OB provider bill for global charges since they have an arrangement?
