Usually, how HMO thru employer health coverage works is this:
Single: $X amount
Employee plus spouse: $Y amount (usually X plus 25-50%)
Family: $Z amount (usually roughly double of X)
So for family coverage, if you want to get the "most bang for your buck", you are better off having a bunch of kids, because you'll pay the same for 11 kids as you will for one.
Many (most?) people do not understand this. I, myself, am unsure why it works like this. So if hairstylist and her dh have a child together, they are paying the family rate. It makes sense to sign up DSD, too, because chances are they aren't paying any more.
Having said that, it seems like hairstylist's DH shouldn't have to pay any out of pocket costs regarding his daughter's health care if she is insured thru him and has Medicaid. If there are any left over, uncovered health expenses, it seems to me only fair that the parents split them 50-50. (Not that I'm a family court judge or anything.
And yes, I agree wholeheartedly with the pp who said that it's silly to mandate in a custody agreement that a parent provide their child with health insurance, since this is not done when parents are married/living together. Seems like discrimination to me.
Thank God DH has good relationship with DSS's mom, and we've never gone to court.
