If he is a veteran and you are in financial stress, you should be able to get the treatments through the VA. You don't need a disability rating to do that. Co pays are $9. Sign up for healthcare at the nearest VA Hospital if you haven't already. If he is already in the system, then go to the hospital's nursing station and see if you can get a referral to where you need to go. Or talk to the patient advocate and see what you can do.
