Oops, I did it too quickly too; just checked my age category. I am 51; have group insurance (HMO), have been on betaseron (3 weeks), copaxone (4 1/2 months) and now tysabri. All of this has been covered 100%. I am having problems with getting my neuro to order a MRI after 6 months on tysabri. He says it is not necessary if I am doing well.
