In 2013, the Senate sent Bill 944, "Veterans Health and Benefits Improvement Act of 2013" to the Senate Committee on Veterans' Affairs. That committee ordered the Congressional Budget Office to prepare a report on the cost effectiveness of Senate Bill 944. On November 12, 2013, the CBO issued its report. The new rules would cost $7 million per year to enforce. The new rules would "save" the VA $5 million per year. That means the new rules will cost the VA $2 million per year.
As we know, Congress never passed the rule changes into law, despite attempts in 2013 and 2014. I like to think that the changes did not pass because our country honors our veterans and the sacrifices they make. But, perhaps this report played another factor.
