20 CFR § 404.1512 - Responsibility for evidence.
(a) Your responsibility -
(1) General. In general, you have to prove to us that you are blind or disabled. You must inform us about or submit all evidence known to you that relates to whether or not you are blind or disabled (see § 404.1513). This duty is ongoing and requires you to disclose any additional related evidence about which you become aware. This duty applies at each level of the administrative review process, including the Appeals Council level if the evidence relates to the period on or before the date of the administrative law judge hearing decision. We will consider only impairment(s) you say you have or about which we receive evidence. When you submit evidence received from another source, you must submit that evidence in its entirety, unless you previously submitted the same evidence to us or we instruct you otherwise. If we ask you, you must inform us about:
(i) Your medical source(s);
(ii) Your age;
(iii) Your education and training;
(iv) Your work experience;
(vi) Your efforts to work; and
(vii) Any other factors showing how your impairment(s) affects your ability to work. In §§ 404.1560 through 404.1569, we discuss in more detail the evidence we need when we consider vocational factors.
(2) Completeness. The evidence in your case record must be complete and detailed enough to allow us to make a determination or decision about whether you are disabled or blind. It must allow us to determine -
(i) The nature and severity of your impairment(s) for any period in question;
(ii) Whether the duration requirement described in § 404.1509 is met; and
(b) Our responsibility -
(1) Development. Before we make a determination that you are not disabled, we will develop your complete medical history for at least the 12 months preceding the month in which you file your application unless there is a reason to believe that development of an earlier period is necessary or unless you say that your disability began less than 12 months before you filed your application. We will make every reasonable effort to help you get medical evidence from your own medical sources and entities that maintain your medical sources' evidence when you give us permission to request the reports.
(i) Every reasonable effort means that we will make an initial request for evidence from your medical source or entity that maintains your medical source's evidence, and, at any time between 10 and 20 calendar days after the initial request, if the evidence has not been received, we will make one follow-up request to obtain the medical evidence necessary to make a determination. The medical source or entity that maintains your medical source's evidence will have a minimum of 10 calendar days from the date of our follow-up request to reply, unless our experience with that source indicates that a longer period is advisable in a particular case.
(ii) Complete medical history means the records of your medical source(s) covering at least the 12 months preceding the month in which you file your application. If you say that your disability began less than 12 months before you filed your application, we will develop your complete medical history beginning with the month you say your disability began unless we have reason to believe your disability began earlier. If applicable, we will develop your complete medical history for the 12-month period prior to the month you were last insured for disability insurance benefits (see § 404.130), the month ending the 7-year period you may have to establish your disability and you are applying for widow's or widower's benefits based on disability (see § 404.335(c)(1)), or the month you attain age 22 and you are applying for child's benefits based on disability (see § 404.350).
(2) Obtaining a consultative examination. We may ask you to attend one or more consultative examinations at our expense. See §§ 404.1517 through 404.1519t for the rules governing the consultative examination process. Generally, we will not request a consultative examination until we have made every reasonable effort to obtain evidence from your own medical sources. We may order a consultative examination while awaiting receipt of medical source evidence in some instances, such as when we know a source is not productive, is uncooperative, or is unable to provide certain tests or procedures. We will not evaluate this evidence until we have made every reasonable effort to obtain evidence from your medical sources.
(3) Other work. In order to determine under § 404.1520(g) that you are able to adjust to other work, we must provide evidence about the existence of work in the national economy that you can do (see §§ 404.1560 through 404.1569a), given your residual functional capacity (which we have already assessed, as described in § 404.1520(e)), age, education, and work experience.
