WASHINGTON (AP) — A Veterans Affairs psychologist denies that she was trying to save money when she suggested that counselors make fewer diagnoses of post-traumatic stress disorder in injured soldiers.

Norma Perez, who helps coordinate a post-traumatic stress disorder clinical team in central Texas, indicated she might have been out of line to cite growing disability claims in her March 20 e-mail titled "Suggestion." She said her intent was simply to remind staffers that stress symptoms could also be adjustment disorder. The less severe diagnosis could save the VA millions of dollars in disability payouts.

"In retrospect, I realize I did not adequately convey my message appropriately, but my intent was unequivocally to improve the quality of care our veterans received," Perez said in testimony prepared for delivery Wednesday before a Senate panel.

The Senate Veterans' Affairs Committee and the VA inspector general are investigating whether there were broader VA policy motives behind the e-mail, which was obtained and disclosed last month by two watchdog groups. The VA has strenuously denied that cost-cutting is a factor in its treatment decisions.

"One question that was raised repeatedly about this latest e-mail was, 'Why would a clinician be so concerned about the compensation rolls?'" said Sen. Daniel Akaka, D-Hawaii, who chairs the Senate panel. "As an oversight body, we must know whether the actions of these VA employees point to a systemic indifference to invisible wounds."
