UNITED STATES DISTRICT COURT MIDDLE DISTRICT OF FLORIDA TAMPA DIVISION

STACEY ZAYAS o/b/o K.K.,

Plaintiff,

v. Case No.: 8:25-cv-02885-AAS

KILOLO KIJAKAZI, Acting Commissioner, Social Security Administration,

Defendant. ________________________________________/

ORDER

Stacey Zayas, on behalf of her minor grandchild, K.K., requests judicial review of the Commissioner of Social Security’s (Commissioner) decision denying K.K.’s claim for Supplemental Security Income (SSI). After reviewing the record, including a transcript of the proceedings before the Administrative Law Judge (ALJ), the administrative record, the pleadings, and the parties’ memoranda, the Commissioner’s decision is AFFIRMED. I. Background A. Procedural Background On January 10, 2022, Ms. Zayas applied for SSI on behalf of K.K., claiming disability beginning June 1, 2021. (Tr. 67, 179, 181–86). Disability examiners denied Ms. Zayas’s application initially and on reconsideration. (Tr. 68–73, 75–82). Ms. Zayas requested and received an administrative hearing before the ALJ, which was held on September 25, 2024. (Tr. 170–73). On

November 4, 2024, the ALJ issued a decision finding K.K. not disabled. (Tr. 21–36). The Appeals Council denied Ms. Zayas’s request for a review of the ALJ’s decision, making the ALJ’s decision the final decision of the Commissioner. (Tr. 8–13). Ms. Zayas now requests review of the

Commissioner’s final decision. (Doc. 1). B. Factual Background K.K. was four years old on his application date, January 10, 2022, and seven years old on the date of the ALJ’s decision, November 4, 2024. (Tr. 31,

68, 181). Ms. Zayas alleged K.K. was disabled due to kidney issues, scoliosis, autism, oppositional defiant disorder, and attention deficit hyperactivity disorder (ADHD). (Tr. 68, 210). II. The Disability Evaluation Process for Children

An individual “under the age of 18 [is] consider[ed] . . . disabled if [the individual] ha[s] a medically determinable physical or mental impairment or combination of impairments that causes marked and severe functional limitations, and that can be expected to cause death or that has lasted or can

be expected to last for a continuous period of not less than 12 months.” 20 C.F.R. § 416.906; see 42 U.S.C. § 1382c(a)(3)(C)(i). When determining whether an individual under the age of eighteen is disabled, an ALJ must follow the three-step sequential inquiry outlined in the Code of Federal Regulations

(Regulations), determining as appropriate whether (1) the claimant is engaging in substantial gainful activity; (2) the claimant has a severe impairment or combination of impairments; and (3) the impairment(s) meet, medically equal, or functionally equal any of the impairments outlined in the

Listings. 20 C.F.R. § 416.924; see also Shinn ex rel. Shinn v. Comm’r of Soc. Sec., 391 F.3d 1276, 1278–79 (11th Cir. 2004) (explaining the three-step sequential evaluation process for children); Banks ex rel. Hunter v. Comm'r of Soc. Sec. Admin., 686 F. App’x 706, 712 (11th Cir. 2017).

With respect to the analysis conducted at step three, an ALJ considers the combined effect of all medically determined impairments, even those that are not severe. 20 C.F.R. §§ 416.923, 416.924a(b)(4), 416.926a(a) and (c). The ALJ then looks to “objective criteria set forth in [the Regulations]” to determine

whether the impairment(s) cause severe and marked limitations. Shinn, 391 F.3d at 1278. The Regulations contain the Listings “specifying almost every sort of [impairment] from which a person can suffer, sorted into general categories.” Id. (citing 20 C.F.R. § 416.925(a)). Each listed impairment contains

a discussion of the different limitations on the child’s abilities that the impairment may impose. Id. (citing 20 C.F.R. § 416.925(a)). Limitations appearing in the Listings “are considered ‘marked and severe.’” Id. (citing 20 C.F.R. § 416.925(a)). Limitations resulting from a child's

impairment(s) meet “the Listings if the child actually suffers from the limitations specified in the Listings for that child's severe impairment.” Id. Limitations resulting from a child's impairments medically equal “the Listings if the child's limitations ‘are at least of equal medical significance to those of a

listed impairment.’” Id. (quotation omitted); see 20 C.F.R. § 416.926). Even if the child’s limitations do not medically equal the Listings, “the ALJ can still conclude that those limitations are ‘functionally equivalent’ to those in the Listings.” Id. To make that determination, “the ALJ assesses the

degree to which the child's limitations interfere with the child's normal life activities,” using “six major domains of life[.]” Id. Those domains are: (i) Acquiring and using information; (ii) Attending and completing tasks; (iii) Interacting and relating with others; (iv) Moving about and manipulating objects; (v) Caring for [one]self; and, (vi) Health and physical well-being.

20 C.F.R. § 416.926a(b)(1); see also T.R.C. v. Comm’r, Soc. Sec. Admin., 553 F. App’x 914, 918 (11th Cir. 2014) (citation omitted). “A child’s impairment is ‘of listing-level severity,’ and so ‘functionally equals the listings,’ if as a result of the limitations stemming from that impairment the child has ‘marked limitations in two of the domains [above], or an extreme limitation in one domain.’” Shinn, 391 F.3d at 1279 (quoting 20 C.F.R. § 416.926a(d) and citing 20 C.F.R. § 416.925(a)).

III. The ALJ’s Decision The ALJ followed the required three-step sequential evaluation process for children. (Tr. 24–31). At step one, after recognizing that K.K. was a preschooler on the date the application was filed and is currently school-aged,

the ALJ determined that K.K. had not engaged in substantial gainful activity since January 10, 2022, the application date. (Tr. 25). Next, at step two, the ALJ found K.K. had these severe impairments: ADHD; autism disorder; idiopathic scoliosis; renal agenesis; oppositional defiance disorder; and anxiety.

(Id.). At step three, the ALJ found that K.K. did not have an impairment or combination of impairments that functionally equals the severity of the Listings. (Tr. 26). In terms of the six major domains of life, the ALJ ascertained

the following: K.K. has less than a marked limitation in the domains of acquiring and using information; attending and completing tasks; interacting and relating with others; moving about and manipulating objects; ability to care for himself; and health and physical well-being. (Id.). Accordingly, the ALJ
