Can i be responsible for my 24 year old daughters medical bill

(Texas)

My daughter was 24 when she went to a doctor in a diffent city. She was technically on my medical insurance but was self supporting. I didn't sign anything guarantee payment on her behalf, i didn't live in the city where she sought treatment. Can i be held responisble for her bills because she was on my employer's group policy? We both live in TX.
