Plaintiff Victoria Flaherty appeals the district court’s order upholding the Commissioner’s denial of her application for social security disability insurance benefits. We exercise jurisdiction under 28 U.S.C. § 1291 and affirm.
Background
Ms. Flaherty alleges disability since March 5, 2002, due to complications from an on-the-job injury in November 2001 in which she was caught in the closing doors of an elevator. She was previously found to be disabled based on an October 1996 application. In 2000, her disability ended. She received a post-secondary education and then worked as a medical assistant and a receptionist. She does not assert that her present claim relates back to her previous disability.
Ms. Flaherty contends that the following conditions have rendered her disabled: migraine, degenerative joint disease, fi-bromyalgia, pain syndrome, limitations in the use of her upper extremities, sleep disorder or sleep apnea, affective disorder, chronic depression, obesity, diabetes, and peripheral neuropathy. An administrative law judge (ALJ) held a hearing at which Ms. Flaherty, her neighbor, and a vocational expert testified. The ALJ determined that Ms. Flaherty retained the residual functional capacity (RFC) to perform her past relevant work as a receptionist. Accordingly, he denied benefits at step four of the five-part sequential evaluation process.
See Fischer-Ross v. Barnhart,
The Appeals Council denied Ms. Flaherty’s request for review, making the ALJ’s decision the final decision of the Commissioner.
Jensen v. Barnhart,
The parties do not dispute that the date Ms. Flaherty was last insured for disability benefits was December 31, 2002. Her last day of work was March 5, 2002. Therefore, she must establish disability between March 5, 2002 and December 31, 2002, the “relevant period.”
See Henrie v. United States Dep’t of Health & Human Servs.,
We review the Commissioner’s decision to ascertain whether it is supported by substantial evidence in the record and to evaluate whether he applied the correct legal standards.
Grogan v. Barnhart,
In this context, “disability” requires both an “inability to engage in any substantial gainful activity” and “a physical or mental impairment, which provides reason for the inability.”
Barnhart v. Walton,
Migraine Evidence
We first address Ms. Flaherty’s claim that the ALJ erred in finding that her migraines were not severe. She relies on a report dated December 7, 2002, prepared by Dr. Van de Graaff following a consultative evaluation, as well as her own reports to various medical providers that headaches were among her complaints. Dr. Van de Graaff stated that Ms. Flaherty had “limitations in her ability to hold down gainful employment secondary to her recurrent and severe migraines, which are not optimally treated at this time.” R. Vol. I, at 273.'
The ALJ gave no weight to Dr. Van de Graaffs opinion that Ms. Flaherty’s migraines were disabling because he did not have a treating relationship with her, he based his opinion on a single, subjective report given to him by Ms. Flaherty, and his opinion was not supported by the evidence of record. We conclude that the ALJ’s reasons for not crediting Dr. Van de Graaffs opinion are in accordance with the governing regulation and case law.
See
20 C.F.R. § 404.1527(d) (listing factors to be considered when “deciding the weight [to be given] to any medical opinion”);
White v. Barnhart,
The ALJ considered both Ms. Flaherty’s reports to medical sources during the relevant period and her testimony at the hearing. R. Vol. I, at 54. He concluded that her claims of “incapacitating migraines [were] not credible to the extent and severity alleged during the relevant period.”
Id.
He noted that none of her treating sources diagnosed her with migraine syndrome and she had not been prescribed medication for migraine. These were appropriate factors for assessing credibility.
See Barnett v. Apfel,
Combination of Impairments
Ms. Flaherty also argues that the ALJ failed to consider the combined impact of all of her impairments. She further maintains that the ALJ did not accord enough weight to her fibromyalgia and that he placed undue weight on the opinion of a State agency physician who did not examine her.
At step four, the ALJ must consider whether the claimant’s “impairment or combination of impairments prevents [her] from performing [her] past work.”
Grogan,
The non-examining physician’s opinion is an acceptable medical source, which the ALJ was entitled to consider.
See
20 C.F.R. § 404.1513(a)(1). Ms. Flah-erty asks us to reweigh the non-examining physician’s opinion and the effect of her fibromyalgia. “[0]ur limited scope of review precludes this court from reweighing the evidence or substituting our judgment for that of the [Commissioner].”
Hamilton v. Sec’y of Health & Human Servs.,
Duty to Develop Record
Ms. Flaherty next contends that the ALJ failed to develop the record to establish the onset date of her disabling migraines. In a social security disability case, the claimant bears the burden to prove her disability.
Hawkins v. Chater,
Ms. Flaherty argues that the ALJ’s duty to develop the record arose from the “conflict or ambiguity in the record” con
Ms. Flaherty also claims the ALJ should have considered Dr. Setty’s April 2003 records and migraine diagnosis. She points to no opinion, however, relating her April 2003 condition to the relevant period — March 5, 2002 to December 31, 2002. Therefore, this evidence did not create a duty to develop the record.
Cf. Potter v. Sec’y of Health & Human Servs.,
RFC Determination
Finally, Ms. Flaherty claims that the ALJ’s RFC determination was flawed because it did not take into account Dr. Van de GraafPs manipulative limitations. She claims she could not perform the frequent handling required of the receptionist position. The ALJ rejected Dr. Van de Graaff s limitations on handling and grasping because the limitations were not only contrary to the other evidence in the record, but also contrary to Dr. Van de Graaff s own examination findings. As discussed above, these were legitimate reasons for rejecting Dr. Van de Graaffs opinion. Accordingly, we find no error.
Conclusion
The judgment of the district court is AFFIRMED.
