Are you moving to Fargo for work, school, or other reasons? I ask because if you are moving for work, your employer should be able to assist you in working out all of the details ahead of time. Contact the Employee Benefits office or whomever you are working with to facilitate your move. If you are moving for school, the University should have a department that assists foreign students transition to the US. Call them and ask for help. If you are moving for personal reasons, unfortunately you may have a bit less support, but there are things you can do in advance of your move to make things run smoothly.
Will your health coverage in Portugal cover you for any period of time after your move? Regardless of the reason for the move, find out from them if there is any way to get an additional month or two of medication before your move. (What would you do if you were traveling on an extended vacation instead of moving?)
Prior to your move to the US, contact the insurance company and let them know that you are a long time Enbrel patient and ask for their help in making sure that there is no lapse in your shot schedule. They will be able to give you contact information for Rheumatologists in Fargo that accept your insurance. Call and make an appointment for as soon as you arrive. Let the appointments clerk know that you are a long time Enbrel patient moving to the area with no (or limited) overlap of medication. Have your doctors in Portugal send this rheumatologist your medical records now. You should also get a copy of the records for your self just in case of a problem.
Prior to your move, contact the Enbrel co-pay assistance plan. https://www.enbrel.com/support/fina....ds&dclid=CKCa5Pe8jdsCFY8ehwodsEIGPw
This program covers all of the cost of Enbrel for the first 6 months and all but $10 per month for the next 6 months. They can also be very helpful in helping you find a Rheumatologist, making sure your insurance covers Enbrel, and other forms of support.
When my son did his (high school) junior yer abroad, the copay assistance program for Remicade was an invaluable resource in helping us to make sure that he did not have a lapse in his care or his infusions. It is obviously a different company, but in my experience, they all pretty much operate the same way. In my son's case, it was simpler and easier to keep his Remicade treatment under our US Health insurance. He saw a French Rheumatologist for care and infusions, and our insurance company shipped the medication directly to the doctor and paid the doctor and infusion center charges. His case was different though since he wouldn't have qualified for Remicade treatment under standard the French healthcare system's protocol. I don't tell you that to worry you. From what I have seen, if you qualify for Enbrel treatment in Portugal, you will qualify in the US.
Your prescription from Portugal will not be valid in the US as the Portuguese doctor is unlikely to be licensed in the US. Generally, you will need to get a prescription from a Rheumatologist in North Dakota. Although there is no rule that General Practitioners can't write prescriptions for medications like Enbrel, generally they won't and generally insurance companies would question it if they did. Depending on your insurance, you will either fill the prescription at your local pharmacy or through a mail order pharmacy. Your Rheumatologist likely will have samples that they could give you to tide you over any delay in insurance approval. Enbrel is an expensive medication, but your insurance company will pay a large portion of the cost and, as mentioned above, Enbrel Copay Support will cover all or most of the remainder.
Good Luck with your move.
