I too am self pay and had the surgery done in Mexico. I went to two doctors who said they would give me fills in California, the first said he wasn't Internationally approved, the 2nd said he couldn't locate the port due to either scar tissue or flippage. I called me surgeon in Mexico flew down and in 2 minutes he accessed the port and gave me my first fill the cost was $95 for fluoro and about $115 for the flight plus two $6 cab fares and $5 for the bus and train. I will probably go to Mexico everytime I need a fill because I really only trust my surgeon Dr. Kuri he knows what he's doing and I believe he's the best. Good luck to you and perhaps you'll think of seeing my Dr. he is 5 minutes from TJ.
