I have been purchasing items for my mother (personal care item, clothing, vitamins, incontinence supplies etc.) & she pays me back by writing a check. I am thinking it would be easier if I could just charge everything to her credit card & she could pay the bill at the end of the month. If she adds me as an authorized user on her credit & needs to apply for Medicaid down the road will this cause a problem? She is needing more & more assistance & I think she may exhaust all her money in a few years. Would these credit card payments cause a problem with the 5 year look back rule?
