ORDER

ROY B. DALTON, JR., District Judge.

In this social security appeal, Plaintiff Jane Jimenez seeks review of the Commissioner of Social Security's final decision denying her application for social security disability benefits. (Doc. 1.) On referral, U.S. Magistrate Judge Daniel C. Irick recommends affirming the Commissioner's final decision. (Doc. 20 ("R&R").) Both Plaintiff and the Commissioner objected to the R&R (Doc. 21 ("Plaintiff's Objection"); Doc. 22 ("Commissioner's Objection")), and the Commissioner responded to Plaintiff's Objection (Doc. 25). On de novo review, the Court finds: (1) the Commissioner's Objection is sustained; (2) Plaintiff's Objection is overruled; (3) the R&R is adopted in part and rejected in part;1 and (4) the Commissioner's final decision is affirmed.

I. BACKGROUND

On October 11, 2012, Plaintiff applied for disability insurance benefits. (Doc. 1; see also R. 112.)2 She alleged a disability onset date of March 30, 2009 and her last date of insured was December 31, 2014. (R. 12.)

After her claims were denied initially and on reconsideration, she requested a hearing before an Administrative Law Judge ("ALJ"). (R. 112.) On March 24, 2015, following a hearing, the ALJ found that Plaintiff was not disabled within the meaning of the Social Security Act ("SSA") between March 30, 2009 and December 31, 2014. (R. 112-125.) Plaintiff sought review of the ALJ's decision, and the Appeals Council remanded the matter to the ALJ to further evaluate Plaintiff's mental impairments "in accordance with the special technique described in 20 CFR 404.1520a." (R. 133-34.) On remand, the ALJ conducted a hearing on April 20, 2017, at which Plaintiff and her attorney appeared. (R. 44-65.)

On May 8, 2017, the ALJ entered an unfavorable decision finding that Plaintiff was not disabled. (R. 10-27.) Following the SSA's five-step sequential process, the ALJ found that Plaintiff had these severe impairments: affective disorder, thyroid disorder, and drug and alcohol abuse. (R. 12.) The ALJ then found that Plaintiff had no impairment or combination of impairments that met or medically equaled the severity of one of the listed impairments in the SSA regulations. (R. 13-14.) The ALJ assessed Plaintiff's residual functional capacity ("RFC"):

(R. 14.) The ALJ found that Plaintiff had no past relevant work and considered whether any jobs existed in significant numbers in the national economy she could perform, finding:

(R. 25-26.)

The ALJ concluded that Plaintiff was "not disabled." (R. 26.) Plaintiff then requested review of the decision by the Appeals Council. (R. 1-6.) Her request was denied, so the ALJ's decision became final. (R. 1.) Plaintiff then sued requesting review of the Commissioner's decision and reversal for an award of benefits or remand. (Doc. 1.) As grounds, Plaintiff cited three assignments of error: (1) the ALJ failed to properly weigh the medical opinion evidence pertaining to her mental impairments; (2) the ALJ failed to properly weigh the medical opinion evidence pertaining to her physical impairments; and (3) the ALJ erred in finding she could perform other work in the national economy. (Doc. 19, pp. 20-48.)

On referral, Magistrate Judge Irick issued a comprehensive report and recommendation finding the Commissioner's decision should be affirmed on all assignments of error. (Doc. 20.) Both parties objected. (Docs. 21, 22.) Plaintiff asserted the Court should reject Magistrate Judge Irick's findings regarding: (1) Plaintiff's mental limitations; (2) the RFC determination; and (3) Plaintiff's ability to perform work that exists in significant numbers in the national economy. (Doc. 21.) The Commissioner responded to Plaintiff's Objection (Doc. 25) and separately objected to the R&R's assumption that Dr. Raul Zimmerman was Plaintiff's treating physician and footnote 9 regarding an acceptable medical source (Doc. 22). Magistrate Judge Irick then issued the Supplemental R&R recommending the Court disregard footnote 9, which neither party objected to. (Doc. 27.) So the Court now reviews the R&R de novo based on Plaintiff's Objection and the remainder of the Commissioner's Objection. The matter is ripe.

II. LEGAL STANDARDS

When a party objects to a magistrate judge's findings, the district court must "make a de novo determination of those portions of the report . . . to which objection is made." 28 U.S.C. § 636(b)(1). The district court "may accept, reject, or modify, in whole or in part, the findings or recommendations made by the magistrate judge." Id. The district court must consider the record and factual issues based on the record independent of the magistrate judge's report. Ernest S. ex rel. Jeffrey S. v. State Bd. of Educ., 896 F.2d 507, 513 (11th Cir. 1990).

III. DISCUSSION

Plaintiff's Objection raises three issues (Doc. 21) and the Commissioner's Objection now raises one (Doc. 22).3 The Court addresses each.

A. Treating Physician Argument

The Commissioner objects to the R&R's recommendation this Court assume Dr. Zimmerman was Plaintiff's treating physician ("Dr. Zimmerman Recommendation"). (Doc. 22, pp. 2-3; see Doc. 20, p. 8 n.6.) The Commissioner contends Plaintiff never challenged the Commissioner's determination that Dr. Zimmerman was not her treating physician, so Plaintiff waived the right to challenge that issue and the "Court should not simply assume for the sake of analysis that Dr. Zimmerman was a treating physician." (Doc. 22, pp. 2-3.)

In the R&R, Magistrate Judge Irick explained that determining whether Dr. Zimmerman was Plaintiff's treating physician was a preliminary issue for the Court to consider before evaluating the weight assigned to the opinions of Dr. Zimmerman and Nurse Brooks. (Doc. 20, p. 8 n.6.) And although Magistrate Judge Irick stated that "the ALJ explicitly found" Dr. Zimmerman was not Plaintiff's treating physician, Magistrate Judge Irick recommended the Court not directly address the issue and simply assume that he was for purposes of the analysis. (Id.) Now, the Commissioner challenges that assumption, arguing that Plaintiff never challenged the ALJ's finding that Dr. Zimmerman was not a treating physician. (Doc. 22, pp. 2-3.)

An ALJ is "required to state with particularity the weight he [gives] the different medical opinions and the reasons therefor." Sharfarz v. Bowen, 825 F.2d 278, 279 (11th Cir. 1987) (per curiam). Without such a statement, a reviewing court cannot determine whether the ultimate decision was supported by substantial evidence. Hudson v. Heckler, 755 F.2d 781, 786 (11th Cir. 1985) (per curiam). Here, the ALJ explicitly found Dr. Zimmerman was not Plaintiff's treating physician—"A review of the treatment records demonstrates that claimant met with Ms. Brooks, not Dr. Zimmerman. There is no evidence that Dr. Zimmerman treated the claimant."—and afforded Dr. Zimmerman's opinion "little weight." (R. 19-20.) The ALJ properly articulated that he found Dr. Zimmerman was not Plaintiff's treating physician and assigned his opinions little weight.

To the extent Plaintiff intended to challenge the weight the ALJ assigned to Dr. Zimmerman's opinion,4 Plaintiff never specifically objected to the ALJ finding he was not a treating physician, and waived any argument on that determination. (See Doc. 19, pp. 24-27); See Sanchez v. Comm'r of Soc. Sec., 507 F. App'x 855, 856 n.1 (11th Cir. 2013) (explaining that the plaintiff "effectively abandoned" a challenge that was not explicitly raised).5 So the Commissioner's Objection is sustained and the R&R is overruled to the extent it assumed Dr. Zimmerman was Plaintiff's treating physician. Dr. Zimmerman is not be considered a treating physician for the analysis.6

B. Mental Impairment Argument

Now the Court turns to Plaintiff's Objection. First, Plaintiff argued the R&R wrongly rejected her first assignment of error—that the ALJ improperly weighed the medical opinion evidence offered to support her mental impairments. (Doc. 21, pp. 1-3.) Plaintiff claims the ALJ erred in according greater weight to the opinion of the non-examining medical expert than to the opinions of Dr. Zimmerman and Nurse Brooks.7 (Id.) The Commissioner responds that Plaintiff waived any challenge to the ALJ's reasons for discounting the opinions of Dr. Zimmerman and Nurse Brooks and Plaintiff's request improperly asks the Court to reweigh the medical evidence. (Doc. 25, pp. 2-3.)

At step four of the sequential evaluation process, the ALJ assesses the claimant's RFC and ability to perform past relevant work. Phillips v. Barnhart, 357 F.3d 1232, 1238 (11th Cir. 2004). In performing its assessment, the ALJ must consider all relevant evidence, including the medical opinions of treating, examining, and non-examining medical sources. See 20 C.F.R. § 404.1545(a)(3); see also Rosario v. Comm'r of Soc. Sec., 490 F. App'x 192, 194 (11th Cir. 2012). Absent good cause, the ALJ gives a treating physician's medical opinion "substantial or considerable weight." Winschel v. Comm'r of Soc. Sec., 631 F.3d 1176, 1179 (11th Cir. 2011). Good cause exists "when the: (1) treating physician's opinion was not bolstered by the evidence; (2) evidence supported a contrary finding; or (3) treating physician's opinion was conclusory or inconsistent with the doctor's own medical records." Id. (quoting Phillips, 357 F.3d at 1241). The ALJ must specify the weight given to each medical opinion and the explain the reasons for assigning such weight to each opinion. Id.

Here, the ALJ assigned "little weight" to the opinions of Dr. Zimmerman and Nurse Brooks. (R. 20.) The ALJ explained that Dr. Zimmerman and Nurse Brooks' opinions were accorded little weight because their opinions were "primarily based on the claimant's report that she experiences exacerbation in her symptoms when she is under stress and that she cannot manage the stress of full time work," which the ALJ concluded was "inconsistent with the record as a whole that shows that the claimant's symptoms are generally well controlled." (R. 20.) In deciding to discount their opinions, the ALJ cited to Plaintiff's hospital admissions, progress reports, and medical evaluation records. (See R. 19-22.)

Plaintiff argues the R&R erred in affirming the ALJ's decision to assign "little weight" to the opinions of Dr. Zimmerman and Nurse Brooks. (Doc. 21, pp. 1-3.) But this argument fails for two reasons. First, Plaintiff did not challenge the ALJ's decision to assign Dr. Zimmerman and Nurse Brooks' opinion "little weight." (Doc. 20, p. 9.) Rather, Plaintiff only argued that the record is replete with evidence supporting Dr. Zimmerman and Nurse Brooks' opinions, but Plaintiff fails to argue that substantial evidence does not support the ALJ's decision to assign the opinions little weight. (See Doc. 19, pp. 20-27.) Plaintiff waived any challenge on this point. See Sanchez, 507 F. App'x at 856 n.1 (explaining that the plaintiff "effectively abandoned" a challenge not explicitly raised).

Second, even if Plaintiff properly raised the challenge, the argument still fails because her objection would require the Court to reweigh the evidence to determine whether the ALJ's finding is supported by substantial evidence. See Dyer v. Barnhard, 395 F.3d 1206, 1210 (11th Cir. 2005) (explaining that when reviewing the Commissioner's decision the Court "may not decide facts anew, reweigh the evidence, or substitute [its] judgment for that of the [Commissioner]." (citations omitted)). And there is substantial evidence, including numerous medical records, supporting the ALJ's decision. (See R. 19-22.) So Plaintiff's argument that "the ALJ erred in according greater weight to the opinion of the [non-examining medical expert] than to Plaintiff's treating physicians," is unavailing.8 (Doc. 21, p. 3) Even if the Court disagrees with the Commissioner's determination, it would not reconsider the weight the Commissioner assigned to the various medical opinions because the ALJ's decision is supported by the record. See D'Andrea v. Comm'r of Soc. Sec. Admin., 389 F. App'x 944, 948 (11th Cir. 2010) (rejecting the argument that the ALJ failed to assign the appropriate weight to the treating physician's opinion "because the ALJ articulated at least one specific reason for disregarding the opinion and the record supports it"). Plaintiff's Objection regarding the mental impairment finding is overruled.

C. RFC Argument

Next, Plaintiff objects to the R&R's finding that substantial evidence existed to support the ALJ's determination she could perform medium work.9(Doc. 21, pp. 3-5.) Specifically, Plaintiff argues that the ALJ had to evaluate the entire record, and she provided sufficient support for a determination she is more limited than the ALJ found. (Id.) She also asserts the ALJ failed to consider her difficulties concentrating and the side effects caused by her medication, which further limit her abilities. (Id.) In opposition, the Commissioner argues that the ALJ did not err in finding that evidence from after the date of insured did not undermine the substantial evidence supporting the RFC determination. (Doc. 25, pp. 3-5.)

First, the Court considers Plaintiff's argument that the ALJ failed to consider evidence that undermines the ALJ's conclusion she could perform medium work. (Doc. 21, pp. 4-5.) Plaintiff contends her physical ailments do not support the ALJ's finding she could perform medium work. (Doc. 21, pp. 3-5; see also Doc. 19, pp. 26-30.) Plaintiff argues the record contains significant evidence that she has degenerative disc disease, osteopenia of the bone, and degenerative scoliosis, which undermine the ALJ's RFC determination. (Doc. 21, pp. 4-5.)

The RFC "is an assessment, based upon all the relevant evidence, of a claimant's remaining ability to do work despite [her] impairments." Lewis v. Callahan, 125 F.3d 1436, 1440 (11th Cir. 1997). Here, the ALJ found Plaintiff had the RFC to perform medium work, with specific limitations. (R. 14.) The ALJ relied on medical evidence in the record to conclude that Plaintiff has "no work preclusive physical limitations" and accorded "little weight" to Plaintiff's own subjective testimony because it was "inconsistent with objective treatment records." (R. 14-25.)

Plaintiff must prove that she is disabled and entitled to disability benefits. Doughty v. Apfel, 245 F.3d 1274, 1278 (11th Cir. 2001). But she failed to raise these physical ailments in her application or at the hearing before the ALJ. (See R. 44-65, 370-71; see also Doc. 1, ¶ 4.) Instead, Plaintiff, represented by counsel, focused the inquiry at the hearing on her mental impairments and did not mention her physical limitations. (See R. 44-65.) While the ALJ must consider all impairments, the ALJ is not required to "scour the medical record searching for other impairments that might be disabling, either individually or in combination, that have not been identified by the claimant." East v. Barnhart, 197 F. App'x 899, 902 (11th Cir. 2006). The ALJ did not have to consider the records Plaintiff now cites to support her Plaintiff's physical impairment argument because she never raised them during the administrative process. See Sullivan v. Comm'r of Soc. Sec., 694 F. App'x 670, 671 (11th Cir. 2017) (holding the ALJ had no duty to investigate a claim the claimant did not present during the application for benefits or offered for disability); see also Robinson v. Astrue, 365 F. App'x 993, 996-97 (11th Cir. 2010) (same); East, 197 F. App'x at 902 (same); Street v. Barnhart, 133 F. App'x 621, 627 (11th Cir. 2005) (same).

Furthermore, many of the records Plaintiff now cites to support her argument are from after the last insured date,10 which the ALJ does not have to consider.11 See Robinson v. Astrue, 235 F. App'x 725, 727 n.1 (11th Cir. 2007) (stating that evidence of disability after the last insured date is not pertinent); Hughes v. Comm'r Soc. Sec. Admin., 486 F. App'x 11, 13-14 (11th Cir. 2012) (finding medical opinions from after the last date insured "not particularly relevant to whether [plaintiff] was disabled"). Plaintiff's Objection on the ALJ's failure to consider certain physical impairments is overruled.12

Next is Plaintiff's argument that the ALJ did not account for the limitations caused by her inability to concentrate. Specifically, she contends the hypothetical questions posed to the vocational expert ("VE") failed to account for her concentration limitations, and the ALJ erred in finding she could perform simple tasks. (Doc. 21, pp. 3-4; see also Doc. 19, pp. 27-28.)

Plaintiff relies on Winschel to assert that an ALJ does not account for a claimant's limitations in concentration, persistence, and pace by restricting the hypothetical question to simple, routine, tasks or unskilled work. (Doc. 21, p. 3-4 (citing Winschel, 631 F.3d at 1180).) But in Winschel the U.S. Court of Appeals for the Eleventh Circuit also explained that "other circuits have held that hypothetical questions adequately account for a claimant's limitations in concentration, persistence, and pace when the questions otherwise implicitly account for these limitations." 631 F.3d at 1180; see also Hines-Sharp v. Comm'r Soc. Sec., 511 F. App'x 913, 916 (11th Cir. 2013) (explaining the ALJ can implicitly account for a claimant's limitations in a hypothetical without specifically using "the magic words concentration, persistence, and pace").

Here, the ALJ's hypothetical posed to the vocational expert included "simple tasks," but also included tasks that "do not require the assistance of other [sic] or require her to assist others in performance of their tasks." (R. 61-62.) That hypothetical was explicitly incorporated into the RFC finding. (R. 14) And the ALJ decision specifically addressed Plaintiff's difficulty concentrating:

(R. 13.) Because the ALJ implicitly, if not expressly, accounted for Plaintiff's limitations concentrating in the VE hypothetical and addressed her limitations in the RFC finding, the ALJ's determination had the requisite evidentiary support. Plaintiff's Objection on this issue is overruled.

Last is Plaintiff's argument that the ALJ failed to consider the side effects caused by her medications. Plaintiff asserts that she took Seroquel to treat her bipolar disorder, which causes various side effects including sleepiness. (Doc. 21, p. 5; see also Doc. 19, p. 31.) And the ALJ's medium work conclusion is faulty because it failed to consider those side effects. (Doc. 21, p. 5.)

But Plaintiff's assertion is belied by the record. The ALJ specifically noted in its decision that Plaintiff informed Nurse Brooks that "Seroquel, which she took at night, was sedating." (R. 20.) And more important, even if Plaintiff is correct, she failed to explain how the alleged error was harmful—i.e. would cause a different RFC finding. See Shineski v. Sanders, 556 U.S. 396, 409 (2009) ("The burden of showing harmfulness is normally on the party attacking an agency's determination."). So Plaintiff's side effect argument fails too. With that, all of Plaintiff's arguments pertaining to the RFC determination are rejected.

D. Ability to Perform Other Work in the National Economy Argument

Last, Plaintiff argues the R&R misinterprets the ALJ's step five finding regarding Plaintiff's ability to perform work that exists in significant numbers in the national economy. (Doc. 21, p. 5; see Doc. 20, pp. 19-23.) Specifically, Plaintiff contends the Medical-Vocational Guidelines ("Grids") direct a finding of disabled because of her limitation to sedentary work, and substantial evidence does not support the ALJ's finding. (Doc. 21, p. 5.) The Commissioner responds that Plaintiff inappropriately asks the Court to reweigh the evidence and decide the facts anew. (Doc. 25, p. 5 (citing Doc. 20, p. 20).) On review, Plaintiff's Objection is overruled.

At step five of the sequential evaluation process, the ALJ considers the claimant's RFC, age, education, and work experience to determine whether he or she can perform other work in the national economy. 20 C.F.R. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v). Here, the ALJ found "there were jobs that existed in significant numbers in the national economy that the claimant could have performed." (R. 25.) That decision was based on the testimony of the VE and consideration of Plaintiff's "age, education, work experience, and [RFC]." (R. 26.) The ALJ concluded Plaintiff was "not disabled." (R. 26.)

Plaintiff argues, as she did in her initial brief, that she should have been deemed disabled based on the Grids, and the ALJ's contrary finding lacks substantial evidentiary support. (Doc. 19, pp. 46-47; Doc. 21, p. 5.) Specifically, she states that "Grid rules 201.04 (sedentary) or 201.06 (sedentary), finds disabled an individual with [her] identical vocational factors." (Doc. 19, p. 46.) Plaintiff argues the ALJ's decision she could perform other work in the national economy was not supported by substantial evidence. (Doc. 21, p. 5.)

But Plaintiff's argument inappropriately invites the Court to find her disabled under the Grids by deciding facts anew and reweighing the evidence. See Dyer, 395 F.3d at 1210 (explaining that when reviewing the Commissioner's decision the Court "may not decide facts anew, reweigh the evidence, or substitute [its] judgment for that of the [Commissioner]." (citations omitted). And further, the Court finds substantial evidence existed to support the ALJ's conclusion that Plaintiff could perform other work in the national economy.

Although the ALJ must use the Grids to determine whether Plaintiff could perform other jobs that exist in the national economy, the ALJ cannot rely exclusively on the Grids when Plaintiff "is unable to perform a full range of work at a given residual functional level or when a claimant has non-exertional impairments that significantly limit basic work skills." Phillips, 357 F.3d at 1242 (collecting cases). Here, the ALJ stated:

(R. 26.) It is clear the ALJ did not mechanically apply the Grids, but, correctly incorporated the VE's testimony to determine whether many jobs existed in the national economy that Plaintiff could perform. The Court overrules Plaintiff's Objection to the finding she could perform work that exists in significant numbers in the national economy.

IV. CONCLUSION

In conclusion, the Commissioner's Objection on the Dr. Zimmerman Recommendation is sustained and Plaintiff's Objection is overruled in its entirety. The Commissioner's final decision denying Plaintiff's claim for disability benefits is affirmed.

Accordingly, it is ORDERED AND ADJUDGED:

DONE AND ORDERED.
