I am single working adult and my mom (a legal permanent resident) lives with me. She is 78 years old and has no income. While trying to seek clarification if she is required to have health insurance, I called the local organization in Georgia who advised that she would be exempt primarily because she is not a working adult. She is neither eligible for medicare nor medicaid.
We are in Georgia.
I have been researching on this and came across your nice / simple site. It talks about many scenarios but does not have any sections for 65/older, retired/non working, income-less dependent exemption.
Please share me any documentation that can help
A 65 plus senior who is not eligible for Medicare can get Marketplace subsidies through a family plan or on their own. Medicare disqualifies one from Marketplace cost assistance, as does retiree, but age alone doesn't. There is no specific exemption, but if she was not claimed as a dependent then she could probably get an exemption due to income.
You can find more information on this page from HealthCare.Gov.
