Medicaid cancels coverage in California (Medi-Cal)?

Medi-Cal cancels coverage for disabled woman in nursing home too long?

So a friend of mine told me his stepdaughter is being kicked out of a nursing home because she has been there too long and her Medi-Cal coverage was terminated. Now him and his wife are besides themselves because they don't know what to do and she has to be out in 30 days. Does Medi-Cal do this to people who require around the clock nursing care due to a traumatic brain injury? I wouldn't think this could even be possible. Is it? Or is there possibly something he is confused about where I'm not getting the true picture of what the issue is?
