Upon a determination by the Commissioner of Social Security that the interest of such individual would be served thereby, such payments shall be made, regardless of the legal competency or incompetency of the individual or eligible spouse, to another individual, or an organization, with respect to whom the requirements of subparagraph (B) have been met (in this paragraph referred to as such individual’s “representative payee”) for the use and benefit of the individual or eligible spouse.

In the case of an individual eligible for benefits under this subchapter by reason of disability, the payment of such benefits shall be made to a representative payee if the Commissioner of Social Security determines that such payment would serve the interest of the individual because the individual also has an alcoholism or drug addiction condition (as determined by the Commissioner) and the individual is incapable of managing such benefits.
