In this section, we explain how we consider age when we decide whether you are disabled.
Your age may or may not be a factor in our determination whether your impairment(s)
meets or medically equals a listing, depending on the listing we use for comparison.
However, your age is an important factor when we decide whether your impairment(s)
is severe (see DI 25220.005) and whether it functionally equals the listings (see DI 25225.001). Except in the case of certain premature infants, as described in DI 25215.010, age means chronological age.
