In determining whether your physical or mental impairment or impairments are of a sufficient medical severity that such impairment or impairments could be the basis of eligibility under the law, we will consider the combined effect of all of your impairments without regard to whether any such impairment, if considered separately, would be of sufficient severity. If we do find a medically severe combination of impairments, the combined impact of the impairments will be considered throughout the disability determination process. If we do not find that you have a medically severe combination of impairments, we will determine that you are not disabled (see § 404.1520).
