Christy, you are reading it right, and better than most caseworkers will. 1634(c) is the DAC protection: when someone loses SSI only because they became entitled to Disabled Adult Child benefits, the state has to keep treating her as an SSI recipient for Medicaid. The DAC money gets disregarded. That is the entire point of the provision, and Darling is the case that says Missouri does not get to skip it by hiding behind 209(b). On the void of the void: get the appeal and hearing request in within 10 days of the notice date, not the 90. Ten days is what keeps her coverage in place while you fight - past that she goes on spend-down 10/1 and you are arguing to get it back instead of to keep it. Name the provision by cite in the request and ask them, in writing, which specific state regulation they used to count the DAC at full value. That question alone ends a lot of these, because there is not one. With MO P&A out of money, look at Legal Services of Eastern Missouri or Legal Aid of Western Missouri depending on your county, and the National Health Law Program takes exactly this kind of DAC case.
