The cost of war -- on veterans' health and taxpayer wallets -- will loom a little larger in the new year when the Department of Veterans Affairs issues a final rule to claim adjudicators to presume three more diseases of Vietnam veterans, including heart disease, were caused by exposure to Agent Orange.

The rule, expected to be published soon, will make almost any veteran who set foot in Vietnam, and is diagnosed with Parkinson's disease, B cell leukemia or ischemic heart disease (known also as coronary artery disease), eligible for disability compensation and VA medical care. The exception would be if credible evidence surfaces of a non-service cause for the ailment.

Katie Roberts, VA press secretary, said no estimates will be available on numbers of veterans impacted or the potential cost to VA until after the rule change takes effect sometime in 2010. But the National Association for Uniformed Services was told by a VA official that up to 185,000 veterans could become eligible for benefits and the projected cost to VA might reach $50 billion, said Win Reither, a retired colonel on the association's executive board.

The association also advised members that VA, to avoid aggravating its claims backlog, intends to "accept letters from family physicians supporting claims for Agent Orange-related conditions." It said thousands of widows whose husbands died of Agent Orange disabilities also will be eligible for retroactive benefits and VA Dependency and Indemnity Compensation.
