Its really important to understand that if you have private insurance like BlueCross etc.,  the VA will charge your deductible for some services.  Which once you hit your deductible out of pocket expenses for a regular doctor are ZERO.  The following info is from a question posed to AI:  The U.S. Department of Veterans Affairs (VA) typically does not charge an insurance deductible for the care they provide through their healthcare system. VA healthcare is generally provided at no cost to veterans, though there are some exceptions. If you're receiving care outside the VA system (e.g., through community care programs or non-VA providers), your private insurance might be billed, and your deductible could apply. In this case, the VA may coordinate with your insurance, and you could be responsible for your deductible or any co-pays based on your insurance plan. If you have a VA health plan, the costs should be minimal unless you're seeking care outside the VA system, so it's best to check with your VA care coordinator to understand what specific charges may apply in your case.
