If I move abroad, can I keep my American health insurance to travel back to the states for an upcoming surgery?

I am an American living in Michigan currently. I was unexpectedly offered a job in the Netherlands that wants me to start in September. My hesitation about taking this job revolves around an upcoming surgery that I have scheduled here in Michigan at the end of this year. I unfortunately have to have corrective jaw surgery. The preparation for the surgery is a long process that involves about a year of orthodontics prior to actually being able to get the surgery, which is why I can’t get it before I move. My current health insurance will cover the surgery. I have health insurance through my husband’s employer. We are on very good terms, but my husband and I are separated and he will not be coming with me to the Netherlands. He will continue to work at his existing job and live in Michigan. I don’t know anything about health insurance and even though I am from the US it confuses the hell out of me. Will the health insurance I have through my husband’s employer still apply if I move abroad and travel back for the surgery? Or would any American health insurance I have no longer apply and the surgery would be an out of pocket cost? I would simply just look into getting the surgery in the Netherlands except my orthodontist who is aligning my bite and teeth is working very closely with my oral surgeon to make sure I have the best surgical outcome. I am very hesitant to just try and find a new surgeon at this point with how far I am in the orthodontics process.
