Section 222(d) of the Social Security Act authorizes the transfer from the Federal Old-Age and Survivors Insurance Trust Fund and the Federal Disability Insurance Trust Fund of such sums as may be necessary to pay for the reasonable and necessary costs of vocational rehabilitation (VR) services provided certain disabled individuals entitled under section 223, 225(b), 202(d), 202(e) or 202(f) of the Social Security Act. The purpose of this provision is to make VR services more readily available to disabled individuals and ensure that savings accrue to the Federal Old-Age and Survivors Insurance Trust Fund and the Federal Disability Insurance Trust Fund. Payment will be made for VR services provided on behalf of such an individual in cases where—

(a) The furnishing of the VR services results in the individual's completion of a continuous 9-month period of substantial gainful activity (SGA) as specified in §§ 404.2110 through 404.2111; or

(b) The individual continues to receive disability payments from us, even though his or her disability has ceased, because of his or her continued participation in an approved VR program which we have determined will increase the likelihood that he or she will not return to the disability rolls (see § 404.2112).
