An individual may qualify for SSI benefits based on eligibility under more than one
category, i.e., aged, blind, or disabled. Benefits under section 1619(a) will only
be paid for months when eligibility is based on disability. Eligibility under 1619(b)
is available to the individual only in those months when eligibility is based on disability
or blindness. Use the category that is most advantageous to the individual, given
their overall circumstances. See SI 00501.300 for more information on multi-category eligibility. SM 01005.010 shows how to properly
code the type of claim.
