I received 10,000. as a gift for Xmas 3-4 years ago, Do I have to pay this back before Medicaid pays at LTC?

Mother is out of money at LTC. Each of my Mothers 5 Children recieved 10,000 as a Xmas gift about 3-4 years ago and another 5,000 as a gift at Easter 3 years ago. Mother went to Nursing home 9 months ago and was private pay, she is out of money at end of month, We haven't filed for Medicaid yet as we was told that Medicaid would look at all her banking for last 5 years and any large amounts of money given out would have to be paid back before Medicaid would pay. Is this true even if money was given as a gift? does anyone know who I should talk to for an answer.
