Hello. i am a US expat here in Portugal and I have GeoBlue. GeoBlue is the international insurance arm of BlueCross. Blue Cross only provides coverage in the US, which is why they are switching you.
I have been very happy with them. You can check their online directory, and if they have agreements with the facility you are going to, you contact them in advance and they usually will do direct billing/payment. (for example, here in the Algarve they have agreements with many Doctors and facilities within the Groupo HPA network).
Be aware: you DO have to get the letter from GeoBlue and take it with you to the doctor when you go, if you want them do do this direct bill though… in my experience, the facilities here in the Algarve do not have a clue who GeoBlue is (even if they are listed as a partner facility) so they will typically not have any agreement information in the local offices/facilities - they only have local Portuguese private insurances in their system. I have successfully given them the pre-pay agreement letter that GB mailed me, and got the direct bill, but sometimes its a bridge a bit too far, and I simply can't make the direct bill work, so I just end up paying for it and get reimbursed.
i have also successfully just paid out of pocket (medical is not even close to the cost it is in the US, so its really never been a burden) and submitted my receipts online to GB. They have been excellent about timely review and reimbursement of my bills within the rules of my specific plan, and I get the reimbursement direct deposited in my bank. I tell them if I want reimbursement in € or $, they do the conversion and boom. the arrives.
Also, you are not limited to any specific facility or doctor if you do the reimbursement route. If the facility is not in their directory network as a partner that does direct bill, not a problem. it's not at all like the US where they will only cover facilities/doctors in their network. As far as GB is concerned, it is my understanding that pretty much any doctor/facility outside of the US is considered in-network. I would call them to confirm this has not changed, but I have not encountered a single rejection from them when using it abroad, and also do not need prior approval to go to anyone I choose. Your plan may or may not have this same coverage.
I have had them for 3 years, and also pay (through the nose) for their coverage on the US—be aware, you wont be able to have ACA insurance in the US if you have an international insurance plan (I cannot speak for Medicare). In the US, you must go to a GB network doc/facility - and it is possible that your current docs/clinics are NOT covered. BCBS networks are different for different plans. They do direct bill to the US in-network facilities though. Another good thing about GB is that they allow me to be in the US up to 9 months a year. Every other company I looked at only allows you to be in the US for 6 months in a 12 month period.
I hope this helps… It has been awhile since you posted, but if it doesn't help you, then hopefully it will help someone else.
