SSI Payment Change Language

The Budget Reconciliation bill finally passed by Congress on February 1 includes the following language on payment of SSI back benefits:

Section 1631(a)(10)(A)(i) (42 U.S.C. 1383(a)(10)(A)(i)) is amended by striking `12' and inserting `3'.

(b) Effective Date- The amendment made by subsection (a) shall take effect 3 months after the date of the enactment of this Act.

This makes the effective date a bit ambiguous. Does it apply to decisions made three months after the President signs the bill or does it apply to decisions implemented three months after the President signs the bill?

The bill also includes language which will require Social Security to do more reviews of Disability Determination Services decisions approving SSI claims.
