George Meuser suffers from schizophrenia and applied for Disability Insurance Benefits principally because of that impairment. But an administrative law judge concluded at Step 2 of the 5-step disability
I. BACKGROÜND
Meuser, who is 46 years old, was diagnosed with schizophrenia in 1996, and for 15 years he managed his symptoms with the antipsychotic drug Zyprexa. Throughout that time, from 1995 through March 2012, Meuser worked in the mail-room at a publishing company. Although he described himself as “socially impaired somewhat,” he generally got along well with his coworkers.
But Meuser’s health began deteriorating in late 2011 after his pharmacist gave him the generic version of Zyprexa. Before that switch, as evidenced by nearly two years of physicians’ progress notes, Meu-ser was sleeping eight to ten-hours per night, was not experiencing side effects from his medication, and was showing “good” and “euthymic” mood and affect, meaning neither elevated nor depressed, see Dorland’s Medical-Dictionary 655 (32d ed. 2012). But after the drug substitution, Meuser started having insomnia and would sleep only four to six hours per night. He said that he could not focus at work. He told clinicians that an increased work load over the preceding six or seven months was causing him stress. Hoping that a break would improve his symptoms, Meu-ser took a leave of absence from his job in December 2011. He apparently was living with his parents at the time, and he continues to live with them.
Meuser changed psychiatrists in January 2012. At that time he began seeing Dr. Charles Rhoton, who rediagnosed Meu-ser’s schizophrenia from.“undifferentiated” to “paranoid type,” which involves “prominent delusions or auditory hallucinations,” see Am. PsyChiatric Ass’n, Diagnostic and Statistical Manual of Mental Disorders 313 (4th ed. text- revision 2000) (DSM-IV-TR). Dr. Rhoton also noted “[pjroblems related to social environment” and assessed Meuser’s Global Assessment of Functioning (GAF) score
The next month Meuser reported to Dr. Rhoton that he was “doing pretty well,” had more energy, was falling asleep easier, and had “been getting out of the house a little more.” Dr. Rhoton noted that Meuser was responding well to his medication and that his mood and affect were normal. Nevertheless, Meuser said, he was not feeling well enough to return to work. Faced with the choice of returning to work
Meuser had applied for DIB on February 27, 2012, and based on medical records through March 2012, psychologist F. Klad-der, an agency consultant, opined that Meuser’s schizophrenia was not a severe impairment. He noted that Meuser’s symptoms had been well controlled for over 15 years and that, although his symptoms were not well controlled with generic medication, Meuser was again “doing well” after switching back to Zyprexa. Dr. Klad-der checked boxes indicating only mild difficulties in activities of daily living, social functioning, and concentration, persistence, and pace. A month later William Shipley, an agency consultant with a Ph.D. in an unspecified field, agreed with Dr. Kladder’s assessment without explanation.
Meuser’s application for benefits then was denied initially and on reconsideration. For the next year and a half, until his hearing before the ALJ, Meuser visited Dr. Rhoton six times as his symptoms waxed and waned. Although at each visit Meuser reported tó Dr. Rhoton that he was “well,” “stable,” “fairly well,” or “okay,” Dr. Rhoton noted during four of those visits that Meuser was exhibiting a blunted affect, and on a fifth visit that he was'dysthymic. Meuser continued to complain about erratic sleep. In November 2012, for example, Meuser reported that sleep was “an issue” but said he did not want to change his medication. Then in February 2013 he reported sleeping only three or four hours some nights and other nights twelve to fourteen hours. And as late as August 2013 he reported sleeping “poorly” and having difficulty “falling asleep and staying asleep.” But Meuser did not report “psychotic symptoms” or “positive symptoms” such as hallucinations, paranoia, or “thought broadcasting/insertion,” see Am. PsyChiateic Ass’n, Diagnostic and Statistical Manual op Mental DISORDERS. 94 (5th ed. 2013) (DSM-V). At Meuser’s last appointment before the September 2013 hearing, Dr. Rhoton noted that his “negative symptoms” (i.e., limited emotional expression and disinterest in work or social activities) “remain prominent,” see DSM-V at 88.
A week after this appointment, Dr. Rhoton completed a mental residual functional capacity assessment, marking boxes for the degree of Meuser’s limitations in various categories. Dr. Rhoton opined that Meuser, in addition to being “moderately” limited in many areas, was “markedly” limited in his abilities to (1) maintain, attention and concentration for extended periods, (2) regularly attend scheduled activities and be punctual, (3) “sustain an ordinary routine without special supervision,” (4) “make simple work-related decisions,” (5) “ask simple questions or request assistance,” (6) accept instructions and criticism, and (7) set realistic goals and make plans. Dr. Rhoton further opined that Meuser was experiencing “extreme” limitations in the abilities to (1) “work in coordination with or proximity to others without being distracted,” (2) “complete a normal workday and workweek:without interruptions from psychologically based symptoms and ... perform at a consistent pace without an unreasonable number and length of rest periods,” and (3) “respond appropriately to changes in the work setting.” Dr. Rhoton wrote that these limitations had been present for over a year and a half, since February 2012.
Prior to the hearing Meuser submitted reports completed by himself and his parents describing his functional limitations. Meuser’s mother described how Meuser’s
Meuser then testified about his schizophrenia at the hearing before the ALJ in September 2013. He said that he cannot sleep more than three to five hours a night. This sleep deprivation left him so tired that he “couldn’t function” at work, and after quitting his job, Meuser said, his condition had not improved. The lack of sleep also affects his short-term memory, Meuser explained, and thus he must write reminders to himself or rely on his parents to help him remember things like doctor’s appointments. He also said that his parents help him with the laundry because he forgets clothes in the dryer. He said he would “really be in a bad spot” without his parents. Meuser described his daily- activities as doing house chores, doing laundry, and “sometimes”, cooking. He said he could drive but had not ventured beyond Henderson, Kentucky, in the previous year (about 87 miles from his home in Princeton, Indiana). He stays “at home most of the time,” said Meuser, and sometimes does not leave the house for days. He testified that he had become more socially withdrawn, and that he had no close friends, only .acquaintances. And when asked about his reaction to social situations, Meuser said: “I just don’t even want to be there. It’s not anything specific with nervousness, or anything like that. It’s just, shut it down, don’t even go. Don’t even think about it.”
The ALJ, in finding at Step 2 that Meu-ser’s schizophrenia was not a severe impairment, asserted that “[sjigns and findings upon objective examination simply do not reflect the presence of a severe physical or mental impairment that more than minimally affects claimant’s ability to perform basic work functions.” The ALJ reasoned, first, that Meuser had been “very stable” on Zyprexa for 14 years,' with no side effects from the medication and GAF scores of 61 to 70. Second, after acknowledging what he described as “some complaints” from Meuser about his sleep while taking the generic form of Zyprexa, the ALJ implied (without saying directly) that Meuser had gotten better after switching back to the brand-name drug. As support for this apparent conclusion that Zyprexa effectively had controlled Meuser’s symptoms, the ALJ asserted that “[throughout the record” Meuser had “denied any psychotic symptoms” and in February 2013 had reported having “no hallucinations or other thought problems.” The ALJ suggested that, although Meuser had reported “some” problems with concentration and sleep in August.2013, his condition was not severe at the time because “his schizophrenia was negative and he was doing okay.” The ALJ. gave “little .weight” to Dr. Rho-
The Appeals Council denied review, thus making the ALJ’s ruling the final decision of the Commissioner of Social Security. See Liskowitz v. Astrue, 559 F.3d 736, 739 (7th Cir. 2009).
II. Analysis
We will uphold an ALJ’s decision if it is supported by substantial evidence, but that standard is not satisfied unless the ALJ has adequately supported his conclusions. See Jelinek v. Astrue, 662 F.3d 805, 811 (7th Cir. 2011).
On appeal, Meuser first argues that a diagnosis of schizophrenia is enough, standing alone, to satisfy the “severe impairment” requirement at Step 2 because that diagnosis, by definition, requires “marked” social or occupational dysfunction, see DSM-V at 99. We have difficulty imagining how an uncontested diagnosis of'schizophrenia (which describes Meuser’s situation) could not survive Step 2. An impairment is “not severe” only if it is “a slight abnormality” that has “no more than a minimal effect on the ability to do basic work activities,” SSR 96-3p, 1996 WL 374181, at *1 (July 2, 1996), such as “[understanding, carrying out, and ' remembering simple instructions,” “[responding appropriately” to supervisors and co-workers, and “[d]ealing with changes in a routine work setting,” 20 C.F.R. § 404.1521. We recently emphasized in rejecting an ALJ’s determination at Step 2 that a claimant’s impairments were not severe, “[t]he Step 2 determination is ‘a de minimis screening for groundless claims.’ ” O’Connor-Spinner v. Colvin, 832 F.3d 690, 697, 2016 WL 4197915, at *6 (7th Cir. Aug. 9, 2016) (quoting Thomas v. Colvin, 826 F.3d 953, 960 (7th Cir. 2016)); see Newell v. Comm’r of Soc. Sec., 347 F.3d 541, 546 (3d Cir. 2003); Smolen v. Chater, 80 F.3d 1273, 1290 (9th Cir. 1996); McDonald v. Sec’y of Health & Human Serus., 795 F.2d 1118, 1122 (1st Cir. 1986).
■Essentially, the ALJ has conflated Steps 2, 4, and 5. Although the ALJ could still find that Meuser, with medication, can perform work and is not disabled, an assessment of the functional limitations caused by an impairment is more appropriate for Steps 4 and 5, not Step 2, See, e.g., Spiva v. Astrue, 628 F.3d 346, 348 (7th Cir. 2010) (schizophrenia severe but not disabling at Step 4); Milcanovic v. Colvin, 572 Fed.Appx. 587, 590-91 (10th Cir. 2014) (schizophrenia severe but not disabling at Step 5); Ferguson v. Comm’r of Soc. Sec., 628 F.3d 269, 271 (6th Cir. 2010) (schizophrenia severe but not disabling at Step 4); Sultan v. Barnhart, 368 F.3d 857, 861-62 (8th Cir. 2004) (schizophrenia severe but not disabling at Step 5); Matlock v. Barnhart, 90 Fed.Appx. 208, 209-10 (9th Cir. 2004) (schizophrenia severe but not disabling at Step 4); Moore v. Sullivan, 895 F.2d 1065, 1068 (5th Cir. 1990) (schizophrenia
We need not resolve this issue, however, because the ALJ made other errors that alone warrant a conclusion that the ALJ’s decision is not supported by substantial evidence. First, Meuser argues, correctly, that the ALJ fundamentally misunderstood the diagnosis and symptoms of schizophrenia by focusing solely on the “positive symptoms,” such as hallucinations, and thinking that “negative symptoms” meant no symptoms. For example, the ALJ reasoned that Meuser’s description of his limitations is not fully credible in part because, although Meuser had problems with sleep, he “had no hallucinations or other thought problems” and “his schizophrenia was negative and he was doing okay” (emphasis added). The ALJ’s mistaken understanding of the medical evidence led him to conclude that Meuser’s mental status' was “essentially normal” when, in fact, Dr. Rhotón’s finding that Meuser’s “[njegative symptoms remain prominent” meant just the opposite—that his emotional expression was impaired and he showed disinterest in work or social activities. Thus, the ALJ improperly played doctor when he ignored expert opinions to arrive at his own, incorrect, interpretation of the medical evidence. See Stage v. Colvin, 812 F.3d 1121, 1125 (7th Cir. 2016); Moon v. Colvin, 763 F.3d 718, 722 (7th Cir. 2014).
The Commissioner does not explicitly deny that the ALJ misunderstood the meaning of “negative symptoms” but contends that any misunderstanding is harmless because the reference to “negative symptoms” in the medical record was merely a “single notation” on which the ALJ did not place undue weight. To the contrary, the ALJ clearly misunderstood the medical evidence and repeatedly relied on the lack of “positive” symptoms and the reference to negative symptoms to conclude that Meuser’s schizophrenia was not severe. The Commissioner further argues that any error with respect to this issue was harmless because Meuser did not show that any limitations lasted for 12 months as required to move on to Step 3, see 20 C.F.R. § 404.1509. But this duration requirement is not part of the definition of “severe.” See id. § 404.1520. Regardless, despite a perfunctory reference to the duration requirement, the ALJ did not rely on this rationale in his opinion, so the Commissioner cannot now rely on it. See SEC v. Chenery Corp., 318 U.S. 80, 87-88, 63 S.Ct. 454, 87 L.Ed. 626 (1943); Kastner v. Astrue, 697 F.3d 642, 648 (7th Cir. 2012).
The ALJ’s misunderstanding of the symptoms of schizophrenia was compound
Next, Meuser argues that the ALJ incorrectly rejected Dr. Rhoton’s opinion that he was markedly or extremely limited in several areas of functioning. Because Dr. Rhoton was Meuser’s treating psychiatrist, his opinion was entitled to controlling weight if “well-supported and not inconsistent with other substantial evidence.” Stage, 812 F.3d at 1126; see Bauer v. Astrue, 632 F.3d 606, 608 (7th Cir. 2008). The ALJ rejected Dr. Rhoton’s opinion because it did not align with his own, incorrect, interpretation of the medical evidence; as such the ALJ’s refusal to give controlling weight to the opinion, is not supported by substantial evidence.
- Moreover, even assuming that there had been a reason to deny controlling weight to Dr. Rhoton’s opinion, the ALJ was “not permitted simply to discard it.” Scrogham v. Colvin, 766 F.3d 686, 697 (7th Cir. 2014). Rather, the ALJ was required to explicitly consider the details of the treatment relationship and explain the weight he was giving the opinion. See 20 C.F.R. § 404.1527; Yurt v. Colvin, 758 F.3d 850, 860 (7th Cir. 2014). He did not. The Commissioner- contends that the ALJ “properly weighed” Dr. Rhoton’s opinion “under the regulatory factors.” This contention is frivolous. The ALJ did not mention any “regulatory factors” when evaluating Dr. Rho-ton’s opinion; the ALJ said only that the opinion merited “little weight.” Looking at the factors, this conclusion is not supportable. Dr. Rhoton is a psychiatrist and for a year and a half was personally responsible for treating Meuser’s schizophrenia. See 20 C.F.R. § 404.1527(c) (explaining that more weight is given to opinions by specialists, to examining and treating relationships, to longer treatment relationships where there are frequent examinations); Bauer, 532 F.3d at 608. The ALJ instead gave “significant weight” to the agency consultants’ opinions, but these consultants did not ex-aminé Meuser, they are not psychiatrists (though one was a psychologist), and they had-reviewed only a fraction of Meuser’s treatment records that were available before Meuser submitted additional evidence. See Goins v. Colvin, 764 F.3d 677, 680 (7th Cir. 2014) (criticizing ALJ’s reliance on consulting physicians’ conclusions that were based on incomplete medical record); Campbell v, Astrue, 627 F.3d 299, 309 (7th Cir. 2010) (same). This error, too, is reason enough to remand the case. See Bauer, 532 F.3d at 608-09.
The preceding errors are sufficiently serious to warrant remanding the case, but we note additional issues that the ALJ must address on remand. Meuser argues that the ALJ’s misunderstanding of the medical evidence led to a flawed finding that Meuser’s testimony about the severity of his schizophrenia was “not fully credible.” The Commissioner contends that Meuser forfeited any challenge to the
Meuser further contends that the ALJ overstated both the effectiveness of his medication and the extent of his daily activities. Regarding the effectiveness of the medication, it is true that, about a month after switching back to Zyprexa, Meuser reported that he was “doing pretty well,” had more energy, was sleeping better, and was getting out of the house more. But “[tjhere can be a great distance between a patient who responds to treatment and one who is able to enter the workforce.” Scott v. Astrue, 647 F.3d 734, 739-40 (7th Cir. 2011). The ALJ acknowledged that Meuser reported “some” problems with sleep; in fact, Meuser consistently complained about his sleep for over a year and a half, reporting as late as February 2013 that he was sleeping only three or four hours some nights and twelve to fourteen hours other nights. The ALJ also emphasized that Meuser was “very stable” on Zyprexa for 14 years, but this evidence was from before the alleged onset date and therefore irrelevant. See Wiese v. Astrue, 652 F.3d 728, 731 (8th Cir. 2009).
And regarding the extent of Meu-ser’s daily activities, the ALJ determined that Meuser was- only mildly limited in activities of daily living and in social functioning. But “[a]n ALJ cannot disregard a claimant’s limitations in performing” daily activities. Moss v. Astrue, 555 F.3d 556, 562 (7th Cir. 2009); see Craft v. Astrue, 539 F.3d 668, 680 (7th Cir. 2008). When assessing Meuser’s activities of daily living, the ALJ relied on Meuser’s ability to, for example, do laundry, cook meals, and complete chores, but the ALJ ignored evidence that Meuser gets help with the laundry from his parents when they retrieve the clothes he leaves in the dryer, that the meals he cooks are simple and prepackaged, and that he rarely leaves the house. Meuser, after all, is not claiming that he is disabled by physical limitations, so the proper focus—ignored by the ALJ—is the effect of Meuser’s schizophrenia on his mental functioning, including his abilities to concentrate, perform work tasks without constant supervision, maintain a consistent pace, and work around and with other persons. Whether or not he can pop a frozen dinner into the microwave or occasionally clean the litterbox is irrelevant. Moreover, the ALJ asserted that Meuser was only mildly limited in social functioning in part because he was able to spend time with his parents and he got along well with coworkers when he did work. But the ALJ disregarded evidence that Meuser was “extremely reclusive,” that he seemed to spend time only with his parents, and that his only interactions with coworkers were before his alleged onset date.
III. Conclusion
Because the ALJ misunderstood the medical evidence and improperly rejected the treating psychiatrist’s opinion, the ALJ’s conclusion that Meuser did not have a severe impairment is not supported by substantial evidence. We therefore REVERSE the judgment of the district court and REMAND the matter to the agency for further proceedings.’
