Health Insurance/Domicile State

Domicile in SD
So you have your SD drivers license, you have your SD vehicle registration(s), you have your SD vehicle insurance, your SD voters registration, all the mail that is sent to your SD address.

Should be able to prove your SD domicile.

Course SD does not participate in the Multi-plan Program within the Health Insurance Marketplace.
Meaning that the medical insurance coverage you have via ACA using SD as domicile is only good for medical coverage within the state of SD.

Any medical coverage/treatment outside the state of SD is cash out of your pocket....on your own---no coverage.

We found out we had no medical insurance for the month of December. The only way we new this is because of a trip to the ER and one night stay in the hospital Dec.31st. I spent Jan. 2nd on the phone trying to straighten all this mess out. It ended up being a typo error between human resources and Blue Cross.

I too would go with federal documents like the Social Security statement, and phone bills, and the rent for your PO box and of course your Driver's license (photo of it) and registration.

We really need to establish a 51st state (Might as well call it the state of confusion) that would be for full time RVers.. Basically all e would need is senators, a representive or two, and a DMV. oh, and the Office in Chicago. (That part is half joke.. Many states have offices in Chicago).

What kind of documentation were they requesting? As a full-timer I can provide several years of cell phone bills as well as Social Security and pension statements all of which show my domicile address in SD. I also have a driver's license dated more than two years ago and a voter registration card. In order for your domicile to be taken seriously you need to transfer your affairs to that address.
