Parents applying for childhood SSI benefits are often confused by how the Social Security Administration evaluates the claim. The SSA looks at the child's functioning in terms of six domains. This entry dealing with Health and Physical Well-Being is the sixth in a series discussing domains of function. In this domain, SSA considers the cumulative physical effects of physical or mental impairments and their associated treatments or therapies on a child's functioning that were not considered in other domains. When the physical impairment(s), mental impairment(s), or combination of physical and mental impairments has physical effects that cause "extreme" limitation in functioning, the child will generally have an impairment(s) that "meets" or "medically equals" a listing.
