The cut off point for a category 7 veteran is about $24,000.
"Draft legislation to change the means test by the VA in determining whether veterans will be placed in enrollment priority group 5 or 7. The current placement eligibility threshold is set at approximately $24,000 regardless of where in the country the veteran is living."
So if you are a Veteran with health problem but not technically disabled and make over 24,000 you help fund the VA.
