After we review all of the evidence relevant to your claim, including medical opinions (see § 404.1527), we make findings about what the evidence shows. In some situations, we may not be able to make these findings because the evidence in your case record is insufficient or inconsistent. We consider evidence to be insufficient when it does not contain all the information we need to make our determination or decision. We consider evidence to be inconsistent when it conflicts with other evidence, contains an internal conflict, is ambiguous, or when the medical evidence does not appear to be based on medically acceptable clinical or laboratory diagnostic techniques. If the evidence in your case record is insufficient or inconsistent, we may need to take additional actions, as we explain in paragraphs (b) and (c) of this section.
(a) If all of the evidence we receive, including all medical opinion(s), is consistent and there is sufficient evidence for us to determine whether you are disabled, we will make our determination or decision based on that evidence.
(b) If any of the evidence in your case record, including any medical opinion(s), is inconsistent, we will weigh the relevant evidence and see whether we can determine whether you are disabled based on the evidence we have.
(c) If the evidence is consistent but we have insufficient evidence to determine whether you are disabled, or if after weighing the evidence we determine we cannot reach a conclusion about whether you are disabled, we will determine the best way to resolve the inconsistency or insufficiency. The action(s) we take will depend on the nature of the inconsistency or insufficiency. We will try to resolve the inconsistency or insufficiency by taking any one or more of the actions listed in paragraphs (c)(1) through (c)(4) of this section. We might not take all of the actions listed below. We will consider any additional evidence we receive together with the evidence we already have.
(1) We may recontact your treating physician, psychologist, or other medical source. We may choose not to seek additional evidence or clarification from a medical source if we know from experience that the source either cannot or will not provide the necessary evidence. If we obtain medical evidence over the telephone, we will send the telephone report to the source for review, signature, and return;
(d) When there are inconsistencies in the evidence that we cannot resolve or when, despite efforts to obtain additional evidence, the evidence is insufficient to determine whether you are disabled, we will make a determination or decision based on the evidence we have.
