20 C.F.R. § 404.2111
The State VR agency may be paid for VR services if such services contribute to the individual's performance of a continuous 9-month period of SGA. The following criteria apply to individuals who received more than just evaluation services. If a State VR agency claims payment for services to an individual who received only evaluation services, it must establish that the individual's continuous period or medical recovery (if medical recovery occurred before completion of a continuous period) would not have occurred without the services provided. In applying the criteria below, we will consider services described in § 404.2114 that were initiated, coordinated or provided, including services before October 1, 1981.
(a) Continuous period without medical recovery. If an individual who has completed a “continuous period” of SGA has not medically recovered as of the date of completion of the period, the determination as to whether VR services contributed will depend on whether the continuous period began one year or less after VR services ended or more than one year after VR services ended.
(2) More than one year.
(b) Continuous period with medical recovery occurring before completion.
(1) If an individual medically recovers before a continuous period has been completed, VR services under paragraph (a) of this section will not be payable unless some VR services contributed to the medical recovery. VR services will be considered to have contributed to the medical recovery if—
(2) In some instances, the State VR agency will not have provided, initiated, or coordinated medical services. If this happens, payment for VR services may still be possible under paragraph (a) of this section if:
