What is the last of the six “functional domains”?
The sixth domain is “health and physical well-being”. This domain considers the cumulative physical effects of physical and mental impairments and any associated treatments or therapies on a child’s functioning that were not considered in the evaluation of the child’s ability to move about and manipulate objects (20 CFR 416.929a(l)).
Social Security regulation 20 CFR416.926a(l)(3) sets forth some examples of limited functioning in this domain that children of any age might have; however the examples do not necessarily describe “marked” or “extreme” limitation in the domain. Some examples of difficulty children could have involving their health and physical well-being are: (i) generalized symptoms, such as weakness, dizziness, agitation (e.g., excitability), lethargy (e.g., fatigue or loss of energy or stamina), or psychomotor retardation because of any impairment(s); (ii) somatic complaints related to an impairment (e.g., seizure or convulsive activity, headaches, incontinence, recurrent infections, allergies, changes in weight or eating habits, stomach discomfort, nausea, headaches or insomnia); (iii) limitations in physical functioning because of treatment (e.g., chemotherapy, multiple surgeries, chelation, pulmonary cleansing, or nebulizer treatments); (iv) exacerbations from an impairment(s) that interfere with physical functioning; or (v) medical fragility requiring intensive medical care to maintain level of health and physical well-being.
If a claimant has no marked limitation in health and physical well-being, she does not fulfill the domain criteria.
