An ad hoc committee will provide an analysis of health care utilizations as they relate to impairment severity and SSA's definition of disability. The committee will identify utilizations that might be good proxies for "listing-level" severity; that is, what represents an impairment, or combination of impairments, that is severe enough to prevent a person from doing any gainful activity, regardless of age, education, or work experience.

The task order objectives for the ad hoc committee are to:

1. Provide a general description of the health care delivery system (for example, Affordable Care Act, move to patient-centered care, medical homes, bundled payments, and other significant changes in the delivery of care);

2. Identify factors that influence a person’s use of health care services;

3. Identify health care utilizations that represent and are a good indicator of impairment severity for the purposes of the disability program;

4. Explain how intervals between utilizations and duration of utilizations affect whether a health care utilization is a good indicator of impairment severity;

5. Explain how types of utilizations are more or less probable for particular medical conditions or combinations of medical conditions;

6. Describe how factors such as poverty and urbanization level affect health care utilizations; and

7. Describe how the health care utilizations interfere with a person’s ability to work.
