20 CFR § 404.1527 - Evaluating opinion evidence for claims filed before March 27, 2017.
(1) Medical opinions. Medical opinions are statements from acceptable medical sources that reflect judgments about the nature and severity of your impairment(s), including your symptoms, diagnosis and prognosis, what you can still do despite impairment(s), and your physical or mental restrictions.
(2) Treating source. Treating source means your own 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.
(b) How we consider medical opinions. In determining whether you are disabled, we will always consider the medical opinions in your case record together with the rest of the relevant evidence we receive. See § 404.1520b.
(c) How we weigh medical opinions. Regardless of its source, we will evaluate every medical opinion we receive. Unless we give a treating source's medical opinion controlling weight under paragraph (c)(2) of this section, we consider all of the following factors in deciding the weight we give to any medical opinion.
(2) Treatment relationship. Generally, we give more weight to medical opinions from your treating sources, since these sources are likely to be the medical professionals most able to provide a detailed, longitudinal picture of your medical impairment(s) and may bring a unique perspective to the medical evidence that cannot be obtained from the objective medical findings alone or from reports of individual examinations, such as consultative examinations or brief hospitalizations. If we find that a treating source's medical opinion on the issue(s) of the nature and severity of your impairment(s) is well-supported by medically acceptable clinical and laboratory diagnostic techniques and is not inconsistent with the other substantial evidence in your case record, we will give it controlling weight. When we do not give the treating source's medical opinion controlling weight, we apply the factors listed in paragraphs (c)(2)(i) and (c)(2)(ii) of this section, as well as the factors in paragraphs (c)(3) through (c)(6) of this section in determining the weight to give the medical opinion. We will always give good reasons in our notice of determination or decision for the weight we give your treating source's medical opinion.
(i) Length of the treatment relationship and the frequency of examination. Generally, the longer a treating source has treated you and the more times you have been seen by a treating source, the more weight we will give to the source's medical opinion. When the treating source has seen you a number of times and long enough to have obtained a longitudinal picture of your impairment, we will give the medical source's medical opinion more weight than we would give it if it were from a nontreating source.
(ii) Nature and extent of the treatment relationship. Generally, the more knowledge a treating source has about your impairment(s) the more weight we will give to the source's medical opinion. We will look at the treatment the source has provided and at the kinds and extent of examinations and testing the source has performed or ordered from specialists and independent laboratories. For example, if your ophthalmologist notices that you have complained of neck pain during your eye examinations, we will consider his or her medical opinion with respect to your neck pain, but we will give it less weight than that of another physician who has treated you for the neck pain. When the treating source has reasonable knowledge of your impairment(s), we will give the source's medical opinion more weight than we would give it if it were from a nontreating source.
(3) Supportability. The more a medical source presents relevant evidence to support a medical opinion, particularly medical signs and laboratory findings, the more weight we will give that medical opinion. The better an explanation a source provides for a medical opinion, the more weight we will give that medical opinion. Furthermore, because nonexamining sources have no examining or treating relationship with you, the weight we will give their medical opinions will depend on the degree to which they provide supporting explanations for their medical opinions. We will evaluate the degree to which these medical opinions consider all of the pertinent evidence in your claim, including medical opinions of treating and other examining sources.
(4) Consistency. Generally, the more consistent a medical opinion is with the record as a whole, the more weight we will give to that medical opinion.
(5) Specialization. We generally give more weight to the medical opinion of a specialist about medical issues related to his or her area of specialty than to the medical opinion of a source who is not a specialist.
(6) Other factors. When we consider how much weight to give to a medical opinion, we will also consider any factors you or others bring to our attention, or of which we are aware, which tend to support or contradict the medical opinion. For example, the amount of understanding of our disability programs and their evidentiary requirements that a medical source has, regardless of the source of that understanding, and the extent to which a medical source is familiar with the other information in your case record are relevant factors that we will consider in deciding the weight to give to a medical opinion.
(d) Medical source opinions on issues reserved to the Commissioner. Opinions on some issues, such as the examples that follow, are not medical opinions, as described in paragraph (a)(1) of this section, but are, instead, opinions on issues reserved to the Commissioner because they are administrative findings that are dispositive of a case; i.e., that would direct the determination or decision of disability.
(1) Opinions that you are disabled. We are responsible for making the determination or decision about whether you meet the statutory definition of disability. In so doing, we review all of the medical findings and other evidence that support a medical source's statement that you are disabled. A statement by a medical source that you are “disabled” or “unable to work” does not mean that we will determine that you are disabled.
(2) Other opinions on issues reserved to the Commissioner. We use medical sources, including your treating source, to provide evidence, including opinions, on the nature and severity of your impairment(s). Although we consider opinions from medical sources on issues such as whether your impairment(s) meets or equals the requirements of any impairment(s) in the Listing of Impairments in appendix 1 to this subpart, your residual functional capacity (see §§ 404.1545 and 404.1546), or the application of vocational factors, the final responsibility for deciding these issues is reserved to the Commissioner.
(e) Evidence from our Federal or State agency medical or psychological consultants. The rules in § 404.1513a apply except that when an administrative law judge gives controlling weight to a treating source's medical opinion, the administrative law judge is not required to explain in the decision the weight he or she gave to the prior administrative medical findings in the claim.
(f) Opinions from medical sources who are not acceptable medical sources and from nonmedical sources.
(1) Consideration. Opinions from medical sources who are not acceptable medical sources and from nonmedical sources may reflect the source's judgment about some of the same issues addressed in medical opinions from acceptable medical sources. Although we will consider these opinions using the same factors as listed in paragraph (c)(1) through (c)(6) in this section, not every factor for weighing opinion evidence will apply in every case because the evaluation of an opinion from a medical source who is not an acceptable medical source or from a nonmedical source depends on the particular facts in each case. Depending on the particular facts in a case, and after applying the factors for weighing opinion evidence, an opinion from a medical source who is not an acceptable medical source or from a nonmedical source may outweigh the medical opinion of an acceptable medical source, including the medical opinion of a treating source. For example, it may be appropriate to give more weight to the opinion of a medical source who is not an acceptable medical source if he or she has seen the individual more often than the treating source, has provided better supporting evidence and a better explanation for the opinion, and the opinion is more consistent with the evidence as a whole.
(2) Articulation. The adjudicator generally should explain the weight given to opinions from these sources or otherwise ensure that the discussion of the evidence in the determination or decision allows a claimant or subsequent reviewer to follow the adjudicator's reasoning, when such opinions may have an effect on the outcome of the case. In addition, when an adjudicator determines that an opinion from such a source is entitled to greater weight than a medical opinion from a treating source, the adjudicator must explain the reasons in the notice of decision in hearing cases and in the notice of determination (that is, in the personalized disability notice) at the initial and reconsideration levels, if the determination is less than fully favorable.
