General

§ 416.901 Scope of subpart.

In order for you to become entitled to any benefits based upon disability or blindness you must be disabled or blind as defined in title XVI of the Social Security Act. This subpart explains how we determine whether you are disabled or blind. We have organized the rules in the following way.

(a) We define general terms, then discuss who makes our disability or blindness determinations and state that disability and blindness determinations made under other programs are not binding on our determinations.

(b) We explain the term disability and note some of the major factors that are considered in determining whether you are disabled in §§ 416.905 through 416.910.

(c) Sections 416.912 through 416.918 contain our rules on evidence. We explain your responsibilities for submitting evidence of your impairment, state what we consider to be acceptable sources of medical evidence, and describe what information should be included in medical reports.

(d) Our general rules on evaluating disability for adults filing new applications are stated in §§ 416.920 through 416.923. We describe the steps that we go through and the order in which they are considered.

(e) Our general rules on evaluating disability for children filing new applications are stated in § 416.924.

(f) Our rules on medical considerations are found in §§ 416.925 through 416.930. We explain in these rules—

(1) The purpose and use of the Listing of Impairments found in appendix 1 of subpart P of part 404 of this chapter;

(2) What we mean by the terms medical equivalence and functional equivalence and how we make those findings;

(3) The effect of a conclusion by your physician that you are disabled;

(4) What we mean by symptoms, signs, and laboratory findings;

(5) How we evaluate pain and other symptoms; and

(6) The effect on your benefits if you fail to follow treatment that is expected to restore your ability to work or, if you are a child, to reduce your functional limitations to the point that they are no longer marked and severe, and how we apply the rule in § 416.930.

(g) In §§ 416.931 through 416.934 we explain that we may make payments on the basis of presumptive disability or presumptive blindness.

(h) In § 416.935 we explain the rules which apply in cases of drug addiction and alcoholism.

(i) In §§ 416.945 through 416.946 we explain what we mean by the term residual functional capacity, state when an assessment of residual functional capacity is required, and who may make it.

(j) Our rules on vocational considerations are in §§ 416.960 through 416.969a. We explain in these rules—

(1) When we must consider vocational factors along with the medical evidence;

(2) How we use our residual functional capacity assessment to determine if you can still do your past relevant work or other work;

(3) How we consider the vocational factors of age, education, and work experience;

(4) What we mean by “work which exists in the national economy”;

(5) How we consider the exertional, nonexertional, and skill requirements of work, and when we will consider the limitations or restrictions that result from your impairment(s) and related symptoms to be exertional, nonexertional, or a combination of both; and

(6) How we use the Medical-Vocational Guidelines in appendix 2 of subpart P of part 404 of this chapter.

(k) Our rules on substantial gainful activity are found in §§ 416.971 through 416.974. These explain what we mean by substantial gainful activity and how we evaluate your work activity.

(l) In §§ 416.981 through 416.985 we discuss blindness.

(m) Our rules on when disability or blindness continues and stops are contained in §§ 416.986 and 416.988 through 416.998. We explain what your responsibilities are in telling us of any events that may cause a change in your disability or blindness status and when we will review to see if you are still disabled. We also explain how we consider the issue of medical improvement (and the exceptions to medical improvement) in determining whether you are still disabled.

§ 416.902 Definitions for this subpart.

As used in the subpart—

(1) Licensed physician (medical or osteopathic doctor);

(2) Licensed psychologist, which includes:

(i) A licensed or certified psychologist at the independent practice level; or

(5) Qualified speech-language pathologist for speech or language impairments only. For this source, qualified means that the speech-language pathologist must be licensed by the State professional licensing agency, or be fully certified by the State education agency in the State in which he or she practices, or hold a Certificate of Clinical Competence in Speech-Language Pathology from the American Speech-Language-Hearing Association;

(6) Licensed audiologist for impairments of hearing loss, auditory processing disorders, and balance disorders within the licensed scope of practice only (with respect to claims filed (see § 416.325) on or after March 27, 2017);

(d) Commissioner means the Commissioner of Social Security or his or her authorized designee.

(e) 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 through 416.269. 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.)

(f) Impairment(s) means a medically determinable physical or mental impairment or a combination of medically determinable physical or mental impairments.

(g) Laboratory findings means one or more anatomical, physiological, or psychological phenomena that can be shown by the use of medically acceptable laboratory diagnostic techniques. Diagnostic techniques include chemical tests (such as blood tests), electrophysiological studies (such as electrocardiograms and electroencephalograms), medical imaging (such as X-rays), and psychological tests.

(h) 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 404 and 416. (See §§ 416.924(c) and 416.926a(e).)

(i) Medical source means an individual who is licensed as a healthcare worker by a State and working within the scope of practice permitted under State or Federal law, or an individual who is certified by a State as a speech-language pathologist or a school psychologist and acting within the scope of practice permitted under State or Federal law.

(j) Nonmedical source means a source of evidence who is not a medical source. This includes, but is not limited to:

(1) You;

(2) Educational personnel (for example, school teachers, counselors, early intervention team members, developmental center workers, and daycare center workers);

(3) Public and private social welfare agency personnel; and

(4) Family members, caregivers, friends, neighbors, employers, and clergy.

(k) Objective medical evidence means signs, laboratory findings, or both.

(l) Signs means one or more anatomical, physiological, or psychological abnormalities that can be observed, apart from your statements (symptoms). Signs must be shown by medically acceptable clinical diagnostic techniques. Psychiatric signs are medically demonstrable phenomena that indicate specific psychological abnormalities, e.g., abnormalities of behavior, mood, thought, memory, orientation, development, or perception and must also be shown by observable facts that can be medically described and evaluated.

(m) State agency means an agency of a State designated by that State to carry out the disability or blindness determination function.

(n) Symptoms means your own description of your physical or mental impairment.

(o) 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.

(p) We or us means, as appropriate, either the Social Security Administration or the State agency making the disability or blindness determination.

(q) 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.
