If you are rated 100% with the VA you will not pay for any medical services at a VA facility. Also the VA cannot bill Medicare or TriCare because they are Federal entities. You do not pay a premium (like Medicare's $104.90 and TriCare Prime) to have VA medical coverage, there are only co-payments but due to your 100% rating you should not have any co-payments. I'm not sure what other answers you are looking for but I can try to assist with clarification. Additionally, you may want to speak with a Veterans Service Officer (VSO) in your area as they may be able to better explain your benefits to you. You can find a VSO through the VA's website at OGC - Accreditation Search
. All VSO services are provided free of charge.
