Can medicaid deny my severely disabled mothers medicaid

Medicaid lost my mother's online renewal through my Texas Benefits , that forced me to file a paper claim and it looks like if they don't renew the medicaid for nursing home resident that my mother has had for the past 8 years then she may loose her benefits , I've only got until June 2021 for them to renew the claim that they screwed up , they are telling me to be patient and wait but I don't trust them after they lost her online renewal and if my mother looses her benefits I won't be able to keep her in the nursing home financially and I don't know what to do.
