The opinion of the court was delivered by: Sam A. Crow, U.S. District Senior Judge
This is an action reviewing the final decision of the Commissioner of Social Security denying the plaintiff disability insurance benefits and supplemental security income payments. The matter has been fully briefed by the parties.
I. General legal standards
The court's standard of review is set forth in 42 U.S.C. § 405(g), which provides that "the findings of the Commissioner as to any fact, if supported by substantial evidence, shall be conclusive." The court should review the Commissioner's decision to determine only whether the decision was supported by substantial evidence and whether the Commissioner applied the correct legal standards. Glenn v. Shalala, 21 F.3d 983, 984 (10th Cir. 1994). Substantial evidence requires more than a scintilla, but less than a preponderance, and is satisfied by such evidence that a reasonable mind might accept to support the conclusion. The determination of whether substantial evidence supports the Commissioner's decision is not simply a quantitative exercise, for evidence is not substantial if it is overwhelmed by other evidence or if it really constitutes mere conclusion. Ray v. Bowen, 865 F.2d 222, 224 (10th Cir. 1989). Although the court is not to reweigh the evidence, the findings of the Commissioner will not be mechanically accepted. Nor will the findings be affirmed by isolating facts and labeling them substantial evidence, as the court must scrutinize the entire record in determining whether the Commissioner's conclusions are rational. Graham v. Sullivan, 794 F. Supp. 1045, 1047 (D. Kan. 1992). The court should examine the record as a whole, including whatever in the record fairly detracts from the weight of the Commissioner's decision and, on that basis, determine if the substantiality of the evidence test has been met. Glenn, 21 F.3d at 984.
The Social Security Act provides that an individual shall be determined to be under a disability only if the claimant can establish that they have a physical or mental impairment expected to result in death or last for a continuous period of twelve months which prevents the claimant from engaging in substantial gainful activity (SGA). The claimant's physical or mental impairment or impairments must be of such severity that they are not only unable to perform their previous work but cannot, considering their age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy. 42 U.S.C. § 423(d).
The Commissioner has established a five-step sequential evaluation process to determine disability. If at any step a finding of disability or non-disability can be made, the Commissioner will not review the claim further. At step one, the agency will find non-disability unless the claimant can show that he or she is not working at a "substantial gainful activity." At step two, the agency will find non-disability unless the claimant shows that he or she has a "severe impairment," which is defined as any "impairment or combination of impairments which significantly limits [the claimant's] physical or mental ability to do basic work activities." At step three, the agency determines whether the impairment which enabled the claimant to survive step two is on the list of impairments presumed severe enough to render one disabled. If the claimant's impairment does not meet or equal a listed impairment, the inquiry proceeds to step four, at which the agency assesses whether the claimant can do his or her previous work; unless the claimant shows that he or she cannot perform their previous work, they are determined not to be disabled. If the claimant survives step four, the fifth and final step requires the agency to consider vocational factors (the claimant's age, education, and past work experience) and to determine whether the claimant is capable of performing other jobs existing in significant numbers in the national economy. Barnhart v. Thomas, 124 S. Ct. 376, 379-380 (2003).
The claimant bears the burden of proof through step four of the analysis. Nielson v. Sullivan, 992 F.2d 1118, 1120 (10th Cir. 1993). At step five, the burden shifts to the Commissioner to show that the claimant can perform other work that exists in the national economy. Nielson, 992 F.2d at 1120; Thompson v. Sullivan, 987 F.2d 1482, 1487 (10th Cir. 1993). The Commissioner meets this burden if the decision is supported by substantial evidence. Thompson, 987 F.2d at 1487.
Before going from step three to step four, the agency will assess the claimant's residual functional capacity (RFC). This RFC assessment is used to evaluate the claim at both step four and step five. 20 C.F.R. §§ 404.1520(a)(4), 404.1520(e,f,g); 416.920(a)(4), 416.920(e,f,g).
On June 10, 2011, administrative law judge (ALJ) James Harty issued his decision (R. at 14-24). Plaintiff alleges that she has been disabled since July 2, 2009 (R. at 14). Plaintiff is insured for disability insurance benefits through December 31, 2013 (R. at 16). At step one, the ALJ found that plaintiff has not engaged in substantial gainful activity since plaintiff's alleged onset date (R. at 16). At step two, the ALJ found that plaintiff had the following severe impairments: post traumatic stress disorder; bipolar disorder I; personality disorder, NOS; schizophrenia; anxiety disorder; and rule out obsessive-compulsive disorder (R. at 17). At step three, the ALJ determined that plaintiff's impairments do not meet or equal a listed impairment (R. at 17). After determining plaintiff's RFC (R. at 19), the ALJ determined at step four that plaintiff is unable to perform her past relevant work (R. at 22). At step five, the ALJ determined that plaintiff could perform other jobs that exist in significant numbers in the national economy (R. at 23). Therefore, the ALJ concluded that plaintiff was not disabled (R. at 24).
III. Did the ALJ err at step two by failing to find that plaintiff's borderline intellectual functioning is a severe impairment?
The burden of proof at step two is on the plaintiff. See Nielson v. Sullivan, 992 F.2d 1118, 1120 (10th Cir. 1993)(the claimant bears the burden of proof through step four of the analysis). A claimant's showing at step two that he or she has a severe impairment has been described as "de minimis." Hawkins v. Chater, 113 F.3d 1162, 1169 (10th Cir. 1997); see Williams v. Bowen, 844 F.2d 748, 751 (10th Cir. 1988)("de minimis showing of medical severity"). A claimant need only be able to show at this level that the impairment would have more than a minimal effect on his or her ability to do basic work activities. Williams, 844 F.2d at 751. However, the claimant must show more than the mere presence of a condition or ailment. If the medical severity of a claimant's impairments is so slight that the impairments could not interfere with or have a serious impact on the claimant's ability to do basic work activities, the impairments do not prevent the claimant from engaging in substantial work activity. Thus, at step two, the ALJ looks at the claimant's impairment or combination of impairments only and determines the impact the impairment would have on his or her ability to work. Hinkle v. Apfel, 132 F.3d 1349, 1352 (10th Cir. 1997). A claimant must provide medical evidence that he or she had an impairment and how severe it was during the time the claimant alleges they were disabled. 20 C.F.R. § 404.1512(c), § 416.912(c).
In his report, Dr. Moeller stated that the WAIS-IV (Wechsler Adult Intelligence Scale-IV) test showed that plaintiff was in the borderline range of intelligence (R. at 420, 414). However, Dr. Moeller did not diagnose plaintiff with borderline intellectual functioning, as noted by the ALJ (R. at 421, 20). In addition, Dr. Moeller never indicated that this impairment would have more than a minimal impact on plaintiff's ability to work. Furthermore, plaintiff does not cite to any evidence that this impairment would have more than a minimal impact on plaintiff's ability to work. For these reasons, the court finds that the ALJ did not err by failing to include this limitation as a severe impairment at step two.
Furthermore, once the ALJ finds that the claimant has any severe impairment, he has satisfied the analysis for purposes of step two. The ALJ's failure to find that additional alleged impairments are also severe is not in itself cause for reversal. However, the ALJ, in determining plaintiff's RFC, must consider the effects of all of the claimant's medically determinable impairments, both those he deems "severe" and those "not severe." Hill v. Astrue, 289 ...
