20 CFR § 404.1506 - When we will not consider your impairment.
(a)Permanent exclusion of felony-related impairment. In determining whether you are under a disability, we will not consider any physical or mental impairment, or any increase in severity (aggravation) of a preexisting impairment, which arises in connection with your commission of a felony after October 19, 1980, if you are subsequently convicted of this crime. Your subsequent conviction will invalidate any prior determination establishing disability if that determination was based upon any impairment, or aggravation, which we must exclude under this rule.
(b)Limited use of impairment arising in prison. In determining whether you are under a disability for purposes of benefit payments, we will not consider any physical or mental impairment, or any increase in severity (aggravation) of a preexisting impairment, which arises in connection with your confinement in a jail, prison, or other penal institution or correctional facility for conviction of a felony committed after October 19, 1980. The exclusion of the impairment, or aggravation, applies in determining disability for benefits payable for any month during which you are confined. This rule does not preclude the establishment of a period of disability based upon the impairment or aggravation. You may become entitled to benefits upon release from prison provided that you apply and are under a disability at the time.
(c)Felonious offenses. We will consider an offense a felony if -
(1) It is a felony under applicable law; or
(2) In a jurisdiction which does not classify any crime as a felony, it is an offense punishable by death or imprisonment for a term exceeding one year.
(d)Confinement. In general, a jail, prison, or other penal institution or correctional facility is a facility which is under the control and jurisdiction of the agency in charge of the penal system or in which convicted criminals can be incarcerated. Confinement in such a facility continues as long as you are under a sentence of confinement and have not been released due to parole or pardon. You are considered confined even though you are temporarily or intermittently outside of the facility (e.g., on work release, attending school, or hospitalized).
