As used in this subpart—
Acceptable medical source refers to one of the sources described in § 416.913(a) who provides evidence about your impairments. It includes treating sources, nontreating sources, and nonexamining sources.
Adult means a person who is age 18 or older.
Child means a person who has not attained age 18.
Commissioner means the Commissioner of Social Security.
Disability redetermination means a redetermination of your eligibility based on disability using the rules for new applicants appropriate to your age, except the rules pertaining to performance of substantial gainful activity. For individuals who are working and for whom a disability redetermination is required, we will apply the rules in §§ 416.260 ff. In conducting a disability redetermination, we will not use the rules for determining whether disability continues set forth in § 416.994 or § 416.994a. (See § 416.987.)
Impairment(s) means a medically determinable physical or mental impairment or a combination of medically determinable physical or mental impairments.
The listings means the Listing of Impairments in appendix 1 of subpart P of part 404 of this chapter. When we refer to an impairment(s) that “meets, medically equals, or functionally equals the listings,” we mean that the impairment(s) meets or medically equals the severity of any listing in appendix 1 of subpart P of part 404 of this chapter, as explained in §§ 416.925 and 416.926, or that it functionally equals the severity of the listings, as explained in § 416.926a.
Marked and severe functional limitations, when used as a phrase, means the standard of disability in the Social Security Act for children claiming SSI benefits based on disability. It is a level of severity that meets, medically equals, or functionally equals the listings. (See §§ 416.906, 416.924, and 416.926a.) The words “marked” and “severe” are also separate terms used throughout this subpart to describe measures of functional limitations; the term “marked” is also used in the listings. (See §§ 416.924 and 416.926a.) The meaning of the words “marked” and “severe” when used as part of the phrase marked and severe functional limitations is not the same as the meaning of the separate terms “marked” and “severe” used elsewhere in 20 CFR 404 and 416. (See §§ 416.924(c) and 416.926a(e).)
Medical sources refers to acceptable medical sources, or other health care providers who are not acceptable medical sources.
Nonexamining source means a physician, psychologist, or other acceptable medical source who has not examined you but provides a medical or other opinion in your case. At the administrative law judge hearing and Appeals Council levels of the administrative review process, it includes State agency medical and psychological consultants, other program physicians and psychologists, and medical experts or psychological experts we consult. See § 416.927.
Nontreating source means a physician, psychologist, or other acceptable medical source who has examined you but does not have, or did not have, an ongoing treatment relationship with you. The term includes an acceptable medical source who is a consultative examiner for us, when the consultative examiner is not your treating source. See § 416.927.
State agency means that agency of a State which has been designated by the State to carry out the disability or blindness determination function.
Treating source means your own physician, psychologist, or other acceptable medical source who provides you, or has provided you, with medical treatment or evaluation and who has, or has had, an ongoing treatment relationship with you. Generally, we will consider that you have an ongoing treatment relationship with an acceptable medical source when the medical evidence establishes that you see, or have seen, the source with a frequency consistent with accepted medical practice for the type of treatment and/or evaluation required for your medical condition(s). We may consider an acceptable medical source who has treated or evaluated you only a few times or only after long intervals (e.g., twice a year) to be your treating source if the nature and frequency of the treatment or evaluation is typical for your condition(s). We will not consider an acceptable medical source to be your treating source if your relationship with the source is not based on your medical need for treatment or evaluation, but solely on your need to obtain a report in support of your claim for disability. In such a case, we will consider the acceptable medical source to be a nontreating source.
We or us refers to either the Social Security Administration or the State agency making the disability or blindness determination.
You, your, me, my and I mean, as appropriate, the person who applies for benefits, the person for whom an application is filed, or the person who is receiving benefits based on disability or blindness.
