can a 501 or not for profit be set up to fund the cost of treatments not covered by insurance?

My son is autistic and in talking with the teachers and other parents our biggest issue is insurance not covering the treatments needed to make our kids the most productive citizens possible. They get you to functional but leave you there when so much more is possible…

We thought if we did collective fundraisers that possibly we could get some things paid for that our kids do without-like adaptive equipment for writing or more therapy for increased motor skills. I realize we could get more big business type donations as a non profit.

I dont know if its possible but we would like to hire an accountant to oversee the moneys and distrubution of it. We also would like to set up an application process to have a impartial person to set up grants for projects, treatments or equipment being funded.
