From EM-15034, just issued by Social Security:
Beginning September 25, 2015, the Social Security Administration (SSA) and VA initiated a weekly information exchange agreement in which the VA provides SSA with information concerning veterans who received the VA 100% P&T [Permanent and Total] disability compensation rating. With this release, when an individual contacts SSA, and their social security number is on our database as having the 100% P&T rating, our users will receive an immediate alert that we must expedite the case.
Additionally, when an alert identifies the individual as having this VA rating, no additional proof of the 100% P&T rating is necessary to expedite the case. ...We owe our veterans a lot but we don't owe veterans who have 100% VA ratings expediting on their Social Security disability claims. These vets aren't in great financial distress. They have their VA benefits. Other disabled people hurtle towards homelessness while vets who don't really need it get expediting. This is wrong.
