MEMORANDUM OPINION AND ORDER

ROZELLA A. OLIVER, Magistrate Judge.

I.

INTRODUCTION

Carolyn Braddock Townsend ("Plaintiff") challenges the Commissioner's denial of her protectively filed application for supplemental security income ("SSI") following an administrative law judge's ("ALJ") decision that she had not been under a disability, as defined in the Social Security Act. Administrative Record ("AR") 22. For the reasons stated below, the Commissioner's decision is AFFIRMED.

II.

PROCEEDINGS BELOW

On September 28, 2011, Plaintiff protectively filed an application for SSI1 alleging disability beginning September 30, 2009 (her alleged onset date ("AOD")). AR 13. Plaintiff's claim was denied initially on January 11, 2012 and on reconsideration on August 22, 2012. Id. On September 6, 2012, Plaintiff filed a written request for hearing, which occurred on February 27, 2013. Id. Represented by a non-attorney representative, Plaintiff appeared and testified, as did an impartial vocational expert ("VE"). Id. On March 22, 2013, the ALJ found that Plaintiff was not disabled, pursuant to the Social Security Act,2 from the AOD through the date of the decision. Id. at 22. The ALJ's decision became the Commissioner's final decision when the Appeals Council denied Plaintiff's request for review. Id. at 5-8. Plaintiff filed the instant action in this Court on January 30, 2015. Dkt. No. 1.

The ALJ followed a five-step sequential evaluation process to assess whether Plaintiff was disabled. 20 C.F.R. §§ 404.1520, 416.920; see also Lester v. Chater, 81 F.3d 821, 828 n.5 (9th Cir. 1995). At step one, the ALJ found that Plaintiff had not engaged in substantial gainful activity since the AOD. AR 15. At step two, the ALJ found that Plaintiff has the following severe impairment: diabetes with possible peripheral neuropathy. Id. at 16. At step three, the ALJ found that Plaintiff "does not have an impairment or combination of impairments that meets or medically equals the severity of one of the listed impairments in 20 CFR Part 404, Subpart P, Appendix 1." Id. at 18 (citations omitted).

At step four, the ALJ found that Plaintiff possessed the residual functional capacity ("RFC") to "perform the full range of medium work as defined in 20 CFR 404.1567(c) and 416.967(c)." Id. Based on Plaintiff's RFC, and the testimony of the VE, the ALJ determined that Plaintiff could perform her past relevant work "as actually and generally performed in the regional and national economy." Id. at 22. Accordingly, the ALJ did not proceed to step five, and instead found that Plaintiff was not disabled pursuant to the Social Security Act. Id.

III.

STANDARD OF REVIEW

Under 42 U.S.C. § 405(g), a district court may review the Commissioner's decision to deny benefits. A court must affirm an ALJ's findings of fact if they are supported by substantial evidence, and if the proper legal standards were applied. Mayes v. Massanari, 276 F.3d 453, 458-59 (9th Cir. 2001). "`Substantial evidence' means more than a mere scintilla, but less than a preponderance; it is such relevant evidence as a reasonable person might accept as adequate to support a conclusion." Lingenfelter v. Astrue, 504 F.3d 1028, 1035 (9th Cir. 2007) (citing Robbins v. Soc. Sec. Admin., 466 F.3d 880, 882 (9th Cir. 2006)). An ALJ can satisfy the substantial evidence requirement "by setting out a detailed and thorough summary of the facts and conflicting clinical evidence, stating his interpretation thereof, and making findings." Reddick v. Chater, 157 F.3d 715, 725 (9th Cir. 1998) (citing Magallanes v. Bowen, 881 F.2d 747, 751 (9th Cir. 1989)).

"[T]he Commissioner's decision cannot be affirmed simply by isolating a specific quantum of supporting evidence. Rather, a court must consider the record as a whole, weighing both evidence that supports and evidence that detracts from the Secretary's conclusion." Aukland v. Massanari, 257 F.3d 1033, 1035 (9th Cir. 2001) (citations and internal quotations omitted). "`Where evidence is susceptible to more than one rational interpretation,' the ALJ's decision should be upheld." Ryan v. Comm'r of Soc. Sec., 528 F.3d 1194, 1198 (9th Cir. 2008) (citing Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005)); see also Robbins, 466 F.3d at 882 ("If the evidence can support either affirming or reversing the ALJ's conclusion, we may not substitute our judgment for that of the ALJ."). The Court may review only "the reasons provided by the ALJ in the disability determination and may not affirm the ALJ on a ground upon which he did not rely." Orn v. Astrue, 495 F.3d 625, 630 (9th Cir. 2007) (citing Connett v. Barnhart, 340 F.3d 871, 874 (9th Cir. 2003)).

IV.

DISCUSSION

Plaintiff raises two issues: (1) whether the ALJ erred at step two of the five-step sequential evaluation process in finding that Plaintiff's mood disorder and right leg lipoma were not severe impairments; and (2) whether the ALJ erred at step four in finding that Plaintiff would be able to perform her past relevant work. Plaintiff's Memorandum in Support of Complaint ("Pl. Memo.") at 2-8, Dkt. No. 23.

A. Plaintiff's "Severe" Impairments At Step Two

Plaintiff contends that the ALJ committed reversible error by not finding that her "right lower extremity lipoma/cyst" and "schizo affective disorder" were severe impairments. Pl. Memo. at 2-3. Defendant, in turn, contends that the ALJ's finding was supported by substantial evidence in the record. See Memorandum in Support of Defendant's Answer ("Def. Memo.") at 1-15, Dkt. No. 25.

The step two inquiry is meant to be a de minimis screening device. Smolen v. Chater, 80 F.3d 1273, 1290 (9th Cir. 1996) (citing Bowen v. Yuckert, 482 U.S. 137, 153-54, 107 S.Ct. 2287, 96 L. Ed. 2d 119 (1987)). At step two, the ALJ identifies a claimant's severe impairments, i.e., impairments that significantly limit his or her ability to do basic work activities.3 20 C.F.R. § 404.1520(a)(4)(ii); Smolen, 80 F.3d at 1290. A determination that an impairment is not severe requires evaluation of medical findings describing the impairment, and an informed judgment as to its limiting effects on a claimant's ability to do basic work activities. Social Security Ruling ("SSR") 85-28, 1985 WL 56856, at *4 (Jan. 1, 1985).4

The ALJ must take into account subjective symptoms in assessing severity, Smolen, 80 F.3d at 1290, but "medical evidence alone is evaluated . . . to assess the effects of the impairment(s) on ability to do basic work activities." SSR 85-28 at *4. An impairment or combination thereof may properly be found not severe if the clearly established objective medical evidence shows only slight abnormalities that minimally affect a claimant's ability to do basic work activities. Webb v. Barnhart, 433 F.3d 683, 687 (9th Cir. 2005); Smolen, 80 F.3d at 1290.

1. Plaintiff's Right Leg Lipoma

At step two, the ALJ found that Plaintiff's "diabetes with possible peripheral neuropathy" was a severe impairment but that Plaintiff's "right leg lipoma" was not because it caused no more than a minimal limitation in Plaintiff's ability to do basic work activities. AR 16. Plaintiff disagrees, and argues that the "medical evidence. . . supports the fact that [her] impairments are clearly severe. . . ." Pl. Memo. at 3.

Plaintiff cites three objective medical records to support her contention. On May 27, 2010, Plaintiff presented at Barstow Community Hospital complaining of right leg pain and swelling. AR 224, 321, 323-25. Plaintiff was discharged with a prescription for pain medications and was instructed to follow-up with her private doctor. Id. at 324. Nearly 16 months later, on September 20, 2011, Plaintiff again presented at Barstow Community Hospital with similar complaints. Id. at 222, 272-77. Diagnostic testing done that day revealed the right leg lipoma.5 Id. at 225, 275, 288-89. And then, nearly eight months later, on May 9, 2012, Plaintiff complained of pain associated with her right leg lipoma during what appears to be an unrelated medical visit. Id. at 264 ("The patient is here to see podiatry clinic today.").

The foregoing establishes that Plaintiff has a right leg lipoma. However, that fact is not in dispute; the ALJ found that Plaintiff's lipoma constitutes a medically determinable impairment. But mere diagnosis of an impairment—or even treatment for it—is insufficient to establish severity at step two, especially when the objective medical evidence in the record fails to show any work-related limitations connected to the impairment. See Harvey v. Colvin, 2013 WL 3899282, at *5 (C.D. Cal. July 29, 2013) (citing Matthews v. Shalala, 10 F.3d 678, 680 (9th Cir. 1993)). There are no medical source statements in the record that support Plaintiff's allegations as to the effect of her lipoma on her ability to do basic work activities. Plaintiff cites her own subjective complaints to support her position. Pl. Memo. at 3 ("Ms. Townsend testified that she was limited to standing only 10 to 15 minutes and walking up to 2 to 3 blocks . . . [and] that she was only able to lift approximately 10 pounds and sit for only 30 minutes at a time.") (citing AR 31-32), 4 ("Plaintiff maintains that her right leg impairment would severely impact . . . her ability to sustain full time . . . employment if she were required to stand and/or walk more than just a few minutes at a time. Thus, her right leg impairment is indeed a "severe" impairment under the Social Security's definition."). In fact, the objective evidence suggests otherwise.

For example, the ALJ accorded the "greatest weight" to the opinion of Robin Alleyne, M.D.,6 a board-certified physician who personally observed and examined Plaintiff on December 6, 2011, less than three months after her September 20, 2011 lipoma-related hospital visit. AR 21. Dr. Alleyne opined that Plaintiff could lift 50 pounds occasionally and 25 pounds frequently; could stand and walk for six hours of an eight-hour workday; had no sitting restrictions; and could frequently climb, balance, kneel, and crawl. Id. at 21, 237-41. The state agency medical consultants reached similar conclusions in August 2012. Id. at 72-91. Thus, the Court finds that the ALJ properly concluded that Plaintiff's right leg lipoma was not a "severe" impairment based on the objective evidence, which shows only an abnormality that minimally affects Plaintiff's ability to do basic work activities.

2. Plaintiff's "Mood Disorder"

The ALJ further found Plaintiff's "mental impairment of a mood disorder" to be non-severe because it only minimally limited her ability to do basic mental work activities. AR 16. Plaintiff disagrees with the ALJ's analysis and maintains that his failure to deem her "schizo affective disorder" severe "constitutes reversible error." Pl. Memo. at 4. However, Plaintiff's argument is unpersuasive because there is no objective medical evidence to support reversing the ALJ's severity determination.

The record clearly establishes that Susan Templeton, a licensed marriage and family therapist, assessed Plaintiff with a schizoaffective disorder, depressed type, on October 17, 2012. AR 376. The record further establishes that Ms. Templeton's assessment was repeated by Denise Persichino, D.O., on December 19, 2012 and on January 30, 2013. Id. at 371-73. But a medical diagnosis, alone, is insufficient to establish a "severe" impairment. Febach v. Colvin, 580 F. App'x 530, 531 (9th Cir. 2014) ("Although [claimant] was diagnosed with depression, that diagnosis alone is insufficient for finding a `severe' impairment[.] . . . There was sufficient evidence. . . for the ALJ to conclude that [his] depression is not `severe,' including reports by at least three of [his] physicians suggesting that his impairment is `non-severe.'"). Indeed, as the Ninth Circuit, in Parks v. Astrue, 304 F. App'x 503 (9th Cir. 2008), noted in affirming an ALJ's step two finding:

Id. at 506.

Here, neither Ms. Templeton nor Dr. Persichino expressed an opinion as to the effect(s), if any, of Plaintiff's diagnosed impairments on her ability to do basic work activities. See AR 371-73, 376. Furthermore, as noted by the ALJ, Plaintiff's "treatment notes indicate sparse treatment." Id. at 16. Plaintiff's primary doctor's treatment notes occasionally reference depression and anxiety, but before Plaintiff's three visits to Barstow Counseling center, it does not appear as though Plaintiff ever sought regular treatment. See, e.g., AR 224, 243-46, 248, 250, 253-56.

Plaintiff argues that because Margaret Donohue, Ph.D., a psychologist who evaluated Plaintiff on November 25, 2011, see AR 230-36, found "that [she] may have difficulty interacting with others based on her interactions with individuals at the time of the consultative examination[,]" the ALJ erred in finding that Plaintiff could perform the duties of a home health aide and child-care worker. Pl. Memo. at 5 (emphasis added); see also AR 235. But Dr. Donohue's finding that Plaintiff may have interactional difficulties, at most, represents a minimal limitation in Plaintiff's ability to do basic mental work activities, and does not support concluding that her impairments were severe. See Webb, 433 F.3d at 687; Smolen, 80 F.3d at 1290. Moreover, Plaintiff failed to mention that most of Dr. Donohue's findings support the ALJ's severity conclusion. For example, Dr. Donohue stated that:

AR 235.

Dr. Donohue was unable to assess whether Plaintiff had "problems with pace and persistence due to [her] lack of cooperation." Id. In fact, Dr. Donohue accused Plaintiff of malingering, which casts doubt upon Plaintiff's credibility. Id.; Mohammad v. Colvin, 595 F. App'x 696, 697 (9th Cir. 2014) (citing Benton ex rel. Benton v. Barnhart, 331 F.3d 1030, 1040-41 (9th Cir. 2003)) (finding that evidence of malingering is sufficient to support a negative credibility determination).7

Thus, the Court finds that the objective medical evidence supports the ALJ's conclusion that Plaintiff's "medically determinable impairment of a mood disorder does not cause more than a minimal limitation in [her] ability to perform basic work activities and is therefore nonsevere." AR 16.

3. Harmless Error

Even assuming that the ALJ incorrectly found that Plaintiff's right leg lipoma and mood disorder did not constitute "severe" impairments, any error was harmless.

First, step two was resolved in Plaintiff's favor, i.e., the ALJ found Plaintiff's "diabetes with possible peripheral neuropathy" to be severe, and properly continued the process until finding that Plaintiff was able to perform past relevant work at step four. Hickman v. Comm'r Soc. Sec. Admin., 399 F. App'x 300, 301 (9th Cir. 2010) (any error in the ALJ's failure to find an impairment severe was harmless, in part, because the ALJ found that claimant "suffered from other severe impairments and, thus, step two was . . . resolved in [her] favor"); Burch, 400 F.3d at 682 ("Assuming without deciding that [omitting obesity at step two] constituted legal error, it could only have prejudiced [claimant] in step three (listing impairment determination) or step five (RFC) because the other steps . . . were resolved in her favor.").

Second, the ALJ considered all of Plaintiff's impairments during his analysis at step four. See, e.g., AR 18 ("[T]he undersigned has considered all symptoms and the extent to which these symptoms can reasonably be accepted as consistent with the objective medical evidence and other evidence[.]"), 19 ("[Plaintiff's] allegations of debilitating pain and mental problems are inconsistent with the objective medical evidence, which indicates an attempt by the claimant to exaggerate the severity of her symptoms."), 20 ("The medical evidence indicates the claimant received routine conservative treatment for complaints of diabetes with neuropathy, right leg pain, and depression."); see also Lewis v. Astrue, 498 F.3d 909, 911 (9th Cir. 2007) (even if the ALJ erred by not including an impairment at step two, any error was harmless because the ALJ considered the limitations posed thereby at step four).

Thus, the ALJ's supposed step two error does not warrant reversal.

B. "Past Relevant Work" At Step Four

Plaintiff contends that the ALJ "committed reversible error at step . . . four of the sequential evaluation process in failing to properly assess Plaintiff's past work history." Pl. Memo. at 6. Defendant, in turn, contends that the ALJ properly found Plaintiff capable of performing her past relevant work. See Def. Memo. at 15-21.

1. ALJ's Decision

The ALJ found that Plaintiff could perform her past relevant work as a home health aide and child-care worker because neither would "require the performance of work-related activities precluded" by her RFC. AR 21. The ALJ explained his finding as follows:

AR 22. Based on the foregoing, the ALJ concluded that Plaintiff was not disabled pursuant to the Social Security Act. Id.

2. Analysis

Plaintiff offers three arguments to support her claim of reversible error. First, Plaintiff argues that neither occupation identified by the ALJ (i.e., home health aide and child-care worker) was "performed at a significant gainful activity level[] such that [it] should be considered as past relevant work." Pl. Memo. at 6. Second, Plaintiff argues that because the record does not contain a description of Plaintiff's child-care worker job, it was improper for the ALJ to find that the job could be performed by Plaintiff "as performed." Id. at 7. Third, Plaintiff argues that she never acquired the skills to perform those "occupations as described in the [DOT]." Id.

a. Substantial Gainful Activity

At step four, the ALJ must decide whether a claimant is able to perform past relevant work ("PRW") given her RFC. See 20 C.F.R. § 416.920(f); Lewis v. Apfel, 236 F.3d 503, 515 (9th Cir. 2001). Prior work is PRW for purposes of a disability benefits application "when it was done within the last 15 years, lasted long enough for [the claimant] to learn to do it, and was substantial gainful activity." 20 C.F.R. § 416.965(a) (emphasis added); Andry v. Colvin, 2013 WL 5305903, at *3 (E.D. Cal. Sept. 19, 2013) (citing SSR 82-62, 1982 WL 31386 (Jan. 1, 1982)) ("[T]here are three elements to the existence of PRW: (1) `recency,' (2) duration, and (3) SGA.") (emphasis in original). Here, the third element is at issue.

Substantial gainful activity is work that is done for pay or profit that involves significant mental or physical activities. Lewis, 236 F.3d at 515. "Earnings can be a presumptive . . . sign of whether a job is substantial gainful activity." Id. Plaintiff contends that her prior jobs (i.e., home health aide and child-care worker) were not performed at "significant gainful activity levels such that they should be considered as [PRW]." Pl. Memo. at 6. Plaintiff explains her contention as follows:

Pl. Memo. at 6-7 (citations omitted). Defendant concedes Plaintiff's argument as to her health aide earnings, but contends that "Plaintiff is wrong in how she calculated, per SSR 83-35, [1983 WL 31257 (Jan. 1, 1983),] her monthly income for her child-care work." Def. Memo. at 16. This Court agrees.

The regulations state, in pertinent part, that if "your work as an employee . . . was continuous without significant change in work patterns or earnings, and there has been no change in the substantial gainful activity earnings levels, your earnings will be averaged over the entire period of work requiring evaluation to determine if you have done substantial gainful activity." 20 C.F.R. § 416.974a(a); see also 20 C.F.R. § 404.1574a(a); SSR 83-35 at *1 ("Earnings are generally averaged over the actual period of time in which work was performed.") (emphasis added). Averaged monthly earnings are then compared to regulatory limits to determine if substantial gainful activity has been presumptively performed. See 20 C.F.R. § 404.1574(b)(2) & 416.974(b)(2); see also Lewis, 236 F.3d at 515; SSR 83-35 at *3. Earnings are averaged over separate periods, not the "the entire period of work," (1) "[w]hen an individual works over a period of time during which the SGA level changes," in which case the earnings are averaged "over each period for which a different SGA level applies," or (2) "when there is significant change in work patterns or earnings during the period of work requiring evaluation[.]" SSR 83-35 at *4.

Plaintiff reported two jobs in the 15 years before she became unable to work due to her impairments: home health aide and child-care worker. AR 181. Plaintiff worked as a child-care worker from March 3, 2008 to September 30, 2009. Id. In 2009, Plaintiff's earnings from her child-care worker job were $10,290. Id. at 174. In 2008, work presumptively constituted substantial gainful activity if the monthly amount earned, on average, exceeded $940. Monthly Substantial Gainful Activity Amounts Chart, available at http://www.ssa.gov/OACT/COLA/sga.html. In 2009, that amount increased to $980. Id. Because Plaintiff worked "over a period of time during which the SGA level change[d]," the Court may properly look at Plaintiff's 2009 earnings rather than the entire period of work. SSR 83-35 at *4. Plaintiff's average monthly earnings in 2009—which is calculated by dividing her earnings by the nine months that she worked (i.e., January 2009 until September 2009)—were approximately $1,143.33. Thus, contrary to Plaintiff's assertion, her 2009 earnings exceed the amount which presumptively constitutes substantial gainful activity.

b. Child Care Worker Description

At step four, the ALJ must determine whether a claimant can perform his or "her [PRW] either as actually performed or as generally performed in the national economy." Lewis v. Barnhart, 281 F.3d 1081, 1083 (9th Cir. 2002) (citing Pinto v. Massanari, 249 F.3d 840, 845 (9th Cir. 2001)); SSR 82-61, 1982 WL 31387, at *1-2 (Jan. 1, 1982). Explicit findings on PRW "as generally performed and as actually performed" are not required. Pinto, 249 F.3d at 845 (emphasis in original). Thus, here, even if Plaintiff's claim (that "[t]here is simply no factual basis" in the record to support the ALJ's finding that she can perform the job of child care worker "as performed," see Pl. Memo. at 7) is correct, her claim is incomplete in that it ignores the fact that the ALJ also found—based on Plaintiff's RFC, the VE's testimony and the DOT—that Plaintiff could perform PRW as generally performed in the national economy as well. AR 22; see also 20 C.F.R. §§ 404.1560(b)(2) & 416.960(b)(2).10

c. Occupational Skills

Plaintiff "maintains that she at no time acquired the skill levels necessary for the performance of [the home health aide and child-care worker] occupations as described in the [DOT]". Pl. Memo. at 7. As Plaintiff notes, "home health aide" is listed as SVP 3, and "child-care worker" is listed as SVP 4 in the DOT. Id.

"`SVP' refers to the `specific vocational preparation' level which is defined in the DOT as `the amount of lapsed time required by a typical worker to learn the techniques, acquire the information, and develop the facility needed for average performance in a specific job-worker situation.'" Bray v. Comm'r of Soc. Sec. Admin., 554 F.3d 1219, 1230 (9th Cir. 2009) (citing Dictionary of Occupational Titles, Appendix C, page 1009 (4th ed.1991)). SVP 3 is "over 1 month up to and including 3 months." Dictionary of Occupational Titles, Appendix C, page 1009 (4th ed.1991). SVP 4 is "over 3 months up to and including 6 months[.]" Id.

As stated in SSR 00-4p, 2000 WL 1898704, at *3 (Dec. 4, 2000):

In her Disability Report, Plaintiff reported working as a home health aide for three years and three months, which is more than the one to three months required by typical workers to learn the techniques, acquire the information, and develop the facility for average performance in that occupation according to the DOT. AR 181. Similarly, Plaintiff reported working as a child-care worker for nine months, which is more than the three to six months required according to the DOT. Id.

Thus, the Court finds that Plaintiff had enough time to acquire the necessary skills for the home health aide and child-care worker occupations. Accordingly, the Court finds that the ALJ properly found that Plaintiff could perform her PRW.

d. Harmless Error

Defendant contends that even "if the ALJ had erred in his Step Four finding, the error would be at most harmless because if the ALJ had proceeded to Step Five (determining whether Plaintiff was able to do any other work), Plaintiff would still be found not disabled under the Medical-Vocational Guideline (the Grids)." Def. Memo. at 19. However, while the ALJ may have satisfied his burden at step five by relying on the Grids, he did not do so in his decision. Rather, the ALJ ended his analysis at step four without making any step five findings. See AR 22. The ALJ's determination of non-disability cannot be affirmed on grounds not articulated by the ALJ. See Molina v. Astrue, 674 F.3d 1104, 1121 (9th Cir. 2012) (reviewing courts may not uphold an agency decision on a ground not relied on by the agency) (citing Sec. & Exch. Comm'n v. Chenery Corp., 332 U.S. 194, 196, 67 S.Ct. 1575, 91 L. Ed. 1995 (1947)). However, because the Court has found that the ALJ's step four finding was proper, harmless error need not be shown here.

V.

CONCLUSION

IT IS ORDERED that Judgment shall be entered AFFIRMING the decision of the Commissioner denying benefits.

IT IS FURTHER ORDERED that the Clerk of the Court serve copies of this Order and the Judgment on counsel for both parties.
