Fetal MR Billing

Could anyone tell me what billing code they are using for Fetal MR? The only code we have is ‘Pelvic MR’. Is that everyone else is using?
I was just curious-I read one of the practices speak of generating 2 reports, one by the Neuroradiologist and the other by a Pediatric radiologist. How is the billing done in such cases?
