Has anyone had a one time referral done by their dependent's PCM during a PCS?

I am PCSing and my daughter has an appointment set up at the new children's hospital prior to my report date. I am going out early to get daycare and everything set up before I sign in. The nurse there mentioned I should have a referral in prior to the appointment so TRICARE doesn't send me a bill.

I talked to the nurse case manager for pediatrics at the new hospital on base. She said there is an option for a one time consult during PCS from the soon to be old PCM to cover anything needed during the PCS. I sent that to the NCM at my daughter's current doctor. She said she talked to Patient Advocate at TRICARE who said that's wrong. That I have to set up an appointment at the new base hospital and they do the referral. The NCM at the new hospital said they can't do anything for her until I in process and am assigned there.

Has anyone else dealt with this?
