Opinion

UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS EASTERN DIVISION

BARBARA L. ON BEHALF OF M.D.L.,

Plaintiff,

No. 24 CV 50350 v.

Magistrate Judge McShain FRANK BISIGNANON, COMMISSIONER OF SOCIAL SECURITY,

Defendant.

MEMORANDUM OPINION AND ORDER

Plaintiff Barbara L. appeals the Commissioner of Social Security’s decision denying the application for benefits she filed on behalf of her minor son, M.D.L. For the following reasons, plaintiff’s motion for summary remand [16] is denied, defendant’s motion for summary judgment [22] is granted, and the denial of benefits is affirmed.1

Background

In October 2021, plaintiff applied for supplemental security income on behalf of M.D.L., alleging that M.D.L. became disabled on August 1, 2015. [13-1] 17. The claim was denied initially, on reconsideration, and after a hearing before an administrative law judge (ALJ). [Id.] 17-27, 66-72, 74-79. The Appeals Council denied review in June 2024, making the ALJ’s decision the agency’s final decision. See 20 C.F.R. §§ 404.955 & 404.981. Plaintiff then appealed to this Court [1], and the Court has subject-matter jurisdiction pursuant to 42 U.S.C. § 405(g).2

The ALJ reviewed the application in accordance with the Social Security Administration’s three-step process for determining whether a minor claimant is disabled. At step one, the ALJ found that M.D.L. had not engaged in substantial gainful activity since the application date. [13-1] 18. At step two, the ALJ determined

Referenced page numbers are taken from the CM/ECF header placed at the top of filings, except for citations to the administrative record [13-1], which refer to the page numbers in the bottom right corner of each page. 2 The parties have consented to the exercise of jurisdiction by a United States Magistrate Judge [6]. that M.D.L. had the following severe impairments: attention deficit hyperactivity disorder (ADHD) and oppositional defiance disorder (ODD). [Id.] 18-19. At step three, the ALJ concluded that M.D.L.’s impairments did not meet, medically equal, or functionally equal the severity of a listed impairment. [Id.] 19-27. The ALJ accordingly ruled that M.D.L. was not disabled.

Legal Standard

Children are considered disabled if they have a “medically determinable physical or mental impairment, which results in marked and severe functional limitations,” that “has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 1382c(a)(3)(C)(i). The regulations establish a three- step process to evaluate whether a child is disabled: (1) the child cannot be engaged in any “substantial gainful activity,” 20 C.F.R. § 416.924(b); (2) the child must have a medically determinable impairment or combination of impairments that qualifies as “severe,” 20 C.F.R. § 416.924(c); and (3) the impairment or impairments must meet, medically equal, or functionally equal the severity of one of the listings in the Social Security regulations, 20 C.F.R. § 416.924(d). The disability analysis for children is not work-focused (as it is for adults), and the relevant question is “whether the child's limitations meet one of the many listed categories of disability or are functionally equivalent to one of them.” McCavitt v. Kijakazi, 6 F.4th 692, 693 (7th Cir. 2021).

At step three, if an impairment does not meet or medically equal a listing, the ALJ considers six domains of functioning to evaluate whether an impairment functionally equals a listing. 20 C.F.R. § 416.926a(b)(1). “These domains are (1) acquiring and using information, (2) attending and completing tasks, (3) interacting and relating with others, (4) moving about and manipulating objects, (5) caring for yourself, and (6) health and physical well-being.” Kristin H. v. O’Malley, No. 20 CV 6362, 2024 WL 1677403, at *2 (N.D. Ill. Apr. 18, 2024). “To functionally equal a listing, the impairment must produce a ‘marked’ limitation in at least two domains of functioning or an ‘extreme’ limitation in one domain.” Id. “If a child meets the above requirements–in other words, does not engage in substantial gainful activity and has a severe impairment that meets, medically equals, or functionally equals a listing– the child will be found disabled.” Id. (internal quotation marks omitted).

The Court reviews the ALJ’s decision to determine if it is supported by substantial evidence. 42 U.S.C. § 405(g). Substantial evidence is “not a high threshold: it means only such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Karr v. Saul, 989 F.3d 508, 511 (7th Cir. 2021) (internal quotation marks omitted). “When reviewing a disability decision for substantial evidence, we will not reweigh the evidence, resolve debatable evidentiary conflicts, determine credibility, or substitute our judgment for the ALJ’s determination so long as substantial evidence supports it.” Warnell v. O’Malley, 97 F.4th 1050, 1052-53 (7th Cir. 2024) (internal quotation marks and brackets omitted).

Discussion

The ALJ ruled that M.D.L. had no limitations in two functional domains (moving about and manipulating objects and health and physical well-being) and less than marked limitations in three other domains (acquiring and using information, attending and completing tasks, and ability to care for himself). [13-1] 20. The ALJ also concluded that M.D.L. had a less-than-marked limitation in interacting and relating with others until December 2022, when the limitation became marked. [Id.] Plaintiff contends that substantial evidence does not support the ALJ’s ruling as to M.D.L.’s limitations with acquiring and using information, attending and completing tasks, and caring for himself. [16] 8-12. Plaintiff maintains that the ALJ merely summarized the evidence in the record without building a logical bridge from that evidence to her conclusion that M.D.L.’s limitations were less than marked. [Id.] 8-9. Plaintiff argues that the ALJ’s errors were harmful because the ALJ “found marked limitations in the domain of interacting with others,” such that a finding that M.D.L. had a marked limitation in any of these three domains would have resulted in a finding that M.D.L. was disabled. [Id.] 13.3 The Court rejects these arguments for the following reasons.

A. Acquiring and Using Information

First, the ALJ’s decision refutes plaintiff’s argument that the ALJ “never explained how [the evidence] supported less than marked limitations” in acquiring and using information. [16] 9.
