I am self employed and 35 on a hdhp from the marketplace. Yearly oop max is like 8k. I want to go to rehab for drug use that I just can't seem to shake on my own. Would going to rehab increase my future rates? Am I better off just saying I don't have insurance? I probably won't use other health care services this year so it's not like I'll have to pay another 8k on other stuff.
