you'll want to shop your options on healthcare. gov. both your wife and your wife's income will be counted so it sounds like she'll likely have to buy a private insurance policy through your state's marketplace. she may qualify for subsidies to help lower the cost.
we are a retired couple. i am on medicare and my wife doesn't have health insurance. her income qualifies her for medicaid but if my income is included she does not qualify. being on medicare the affordable care act doesn't affect me. shouldn't we be looking for an individual plan for her?
