Harmless Error for Misapplied § 404.1520c Medical-Opinion Factors When Only One Potential “Marked” Mental Limitation Would Not Change Disability Outcome

Introduction

Dimitrios Liapis v. Frank Bisignano is a Seventh Circuit Social Security disability appeal addressing how Administrative Law Judges (ALJs) must evaluate medical opinions under 20 C.F.R. § 404.1520c—and when errors in that evaluation justify remand.

The claimant, Dimitrios George Liapis, alleged disability beginning in December 2019 based on multiple physical conditions (back, knee, ankle/foot injury, chronic pain requiring cane use) and mental conditions (bipolar disorder and anxiety, treated with significant psychotropic medications with documented management issues).

A key dispute centered on consultative psychologist Dr. Mark Pushkash, Ph.D., who opined that Liapis’s ability to concentrate and persist in a work environment would be markedly impaired due to chronic pain and anxiety/depression. The ALJ found Dr. Pushkash’s opinion “generally unpersuasive,” denied benefits, and the district court affirmed. On appeal, Liapis challenged only the ALJ’s handling of Dr. Pushkash’s opinion.

The Seventh Circuit identified multiple errors in the ALJ’s opinion-evaluation analysis but held them harmless because, even crediting Dr. Pushkash, Liapis still would not meet the regulatory threshold for disability based on the “paragraph B” mental-functioning criteria.

Summary of the Opinion

The Seventh Circuit affirmed the denial of benefits. It held:

• The ALJ committed several legal and logical errors in evaluating Dr. Pushkash’s opinion under § 404.1520c, including failing to explain the required factors of supportability and consistency.
• The ALJ also erred by discounting Dr. Pushkash for performing a one-time exam while crediting other one-time examiners; by treating pain-related mental effects as outside a psychologist’s competence; and by asserting “good symptom control” and “conservative treatment” without engaging contrary record evidence.
• Despite these errors, the court held remand was unnecessary because the mistakes did not affect the outcome: at most, Dr. Pushkash would support one “marked” limitation (concentration/persistence/pace), which is insufficient to establish disability under the relevant listings framework requiring two “marked” limitations or one “extreme” limitation.

Analysis

Precedents Cited

1) Finality and posture of review

Poole v. Kijakazi framed the procedural posture: once the Appeals Council declines review, the ALJ decision is the agency’s final word. This mattered because the Seventh Circuit reviewed the ALJ’s reasoning as the operative administrative decision.

2) Standard of review: substantial evidence, legal error, and “logical bridge”

Gedatus v. Saul supplied the core review standards: the court reviews the district court de novo but applies a deferential standard to the ALJ, reversing only for lack of substantial evidence or legal error. Gedatus also reinforced the Seventh Circuit’s “logical bridge” requirement—i.e., the ALJ must connect evidence to conclusions in a reasoned way.

Lopez v. Barnhart was cited (via Gedatus) for the same substantial-evidence/legal-error review framework under 42 U.S.C. § 405(g).

Moore v. Colvin further articulated the “logical bridge” standard, which the court used repeatedly to identify internal inconsistencies and unexplained conclusions in the ALJ’s handling of Dr. Pushkash’s opinion.

Warnell v. O'Malley provided an important constraint: while ALJs must build a logical bridge, they need not address every piece of evidence or fully summarize the record. The Seventh Circuit used Warnell to avoid imposing an “exhaustive discussion” requirement, while still faulting the ALJ for missing required regulatory explanations and for making conclusory assertions.

3) The revised medical-opinion regulation and factor articulation

Albert v. Kijakazi was used to situate the dispute in the post-update regulatory regime. Under the updated framework, the opinion emphasized the text of § 404.1520c(b)(2): ALJs must explain supportability and consistency, but they are not required to articulate the “relationship,” “specialization,” and “other factors” unless special circumstances apply. The court rejected the claimant’s argument that those latter factors always require “some consideration,” distinguishing older cases decided under the prior regime.

4) Selective consideration, internal inconsistency, and improper medical judgment

Myles v. Astrue supported the proposition that ALJs may not selectively consider medical reports. The court used Myles to criticize the ALJ’s inconsistent reliance on one-time consultative examiners: discounting Dr. Pushkash for a one-time exam while crediting other one-time examiners suggests impermissible selectivity rather than neutral factor application.

Lothridge v. Saul was invoked for the rule that internal inconsistency in an ALJ’s opinion can undermine the logical bridge. The opinion applied this when the ALJ discounted Dr. Pushkash for referencing pain’s impact on mental function while crediting another psychologist who similarly tied chronic pain to functional limitations.

Goins v. Colvin was cited to caution that ALJs may not make medical-severity assessments that require physician expertise. The court relied on Goins when criticizing the ALJ’s unsupported characterization of the claimant’s symptom control and treatment conservativeness—particularly given extensive medication regimens and significant surgery.

5) Pain as a source of mental functional limitations

Simila v. Astrue and Carradine v. Barnhart were central to rejecting the ALJ’s notion that a psychologist lacks competence to opine on how physical pain affects mental functioning. These cases recognize that pain can impair concentration, persistence, and pace and that mental health professionals may assess pain-related cognitive/attention impacts.

6) Treatment characterization and evidentiary meaning

Scrogham v. Colvin was used to show that extensive treatment—powerful medications and willingness to undergo risky or invasive procedures—can corroborate, rather than undermine, allegations of severity. The Seventh Circuit used Scrogham to reject the ALJ’s conclusory description of “conservative treatment,” noting the record’s heavy psychotropic regimen and ankle fusion surgery.

7) Harmless error in administrative review

Butler v. Kijakazi and McKinzey v. Astrue provided the operative harmless-error test. Butler recognized harmless error’s applicability to administrative review, and McKinzey supplied the “predict with great confidence” formulation: remand is unnecessary when the court is convinced the agency would reach the same result.

Legal Reasoning

1) What the ALJ did wrong under § 404.1520c

The court identified four principal errors in the ALJ’s evaluation of Dr. Pushkash:

1. Failure to articulate supportability and consistency: The ALJ did not explain how Dr. Pushkash’s opinion was unsupported by his own objective findings or inconsistent with other evidence. Instead, the ALJ emphasized factors that do not require articulation (one-time exam; specialization), effectively reversing the regulation’s hierarchy. This was treated as legal error.
2. Illogical reliance on “one-time exam”: The ALJ discounted Dr. Pushkash for evaluating Liapis once, yet credited multiple other doctors who also evaluated him once. The Seventh Circuit viewed this as a logical-bridge failure and a form of selective reasoning.
3. Improper dismissal of pain-related psychological effects: The ALJ suggested a psychologist lacked expertise to opine on the effect of chronic pain on concentration/persistence. The court rejected this as inconsistent with Seventh Circuit precedent recognizing pain’s mental-functional impacts.
4. Unsupported “good symptom control” and “conservative treatment” characterization: The ALJ asserted overall good control with conservative treatment without analyzing contrary evidence, including strong psychotropic and pain medications, lithium toxicity, ongoing anxiety/racing thoughts, and major ankle surgeries.

2) Why the errors did not matter (harmless error)

The court’s harmless-error conclusion turned on (a) the limited scope of the appeal and (b) the structure of the mental-impairment listings criteria.

• Scope of challenge: Liapis challenged only the ALJ’s treatment of Dr. Pushkash. The remainder of the ALJ decision was not placed in dispute on appeal, narrowing what could change on remand.
• Regulatory threshold for disability based on “paragraph B” mental functioning: Under 20 C.F.R. Part 404, Subpart P, Appendix 1, § 12.00A(2)(b), a claimant must show two “marked” limitations among four functional areas, or one “extreme” limitation. Dr. Pushkash’s distinctive finding was a single marked limitation in concentrating, persisting, or maintaining pace.
• No second marked/extreme limitation identified: Dr. Pushkash’s own report supported adequate functioning in understanding/remembering instructions and relating to supervisors/coworkers (with medication), aligning with the ALJ’s non-marked findings in other domains.
• Overwhelming contrary medical consensus on concentration/persistence/pace: Four other doctors concluded Liapis could sustain simple tasks within acceptable attention/persistence/pace tolerances. The court stated Dr. Pushkash’s contrary view would be outweighed and would not alter the ALJ’s functional ratings.

Putting these points together, the Seventh Circuit applied McKinzey v. Astrue to conclude it could “predict with great confidence” that the ALJ would deny benefits again—even if Dr. Pushkash were found persuasive—because a single marked limitation cannot establish disability under the governing criteria.

Impact

The opinion has three practical effects in Seventh Circuit Social Security litigation:

1. Reinforces the post-2017 articulation rule’s structure: It underscores that ALJs must explain supportability and consistency, and confirms that the regulation’s text does not require articulation of the other factors in ordinary cases.
2. Limits remands where the challenged evidence cannot change the legal outcome: The decision illustrates a rigorous harmless-error approach: even significant analytical defects may not justify remand if the claimant cannot, as a matter of regulatory thresholds, reach disability (e.g., only one possible marked limitation).
3. Rejects categorical skepticism toward pain-based mental limitations by psychologists: By invoking Simila v. Astrue and Carradine v. Barnhart, the court signals that ALJs should not dismiss psychological opinions merely because they discuss pain’s cognitive/attention effects.

Complex Concepts Simplified

Substantial evidence

A deferential standard asking whether a reasonable person could accept the evidence as adequate to support the ALJ’s conclusion—even if other evidence might support a different result.

Logical bridge

The ALJ must explain reasoning in a way that connects evidence to conclusions so a reviewing court can follow how the result was reached.

§ 404.1520c “supportability” and “consistency”

Supportability asks whether the doctor’s own explanations and objective findings support the opinion. Consistency asks whether the opinion aligns with the rest of the record evidence. These are the two factors the ALJ generally must explain.

Harmless error

Even if the ALJ made mistakes, a court will not remand if it is confident the agency would reach the same result on remand.

“Marked” vs. “extreme” limitations (mental functioning)

These are severity ratings for functional limits. For many mental-disorder listings, disability generally requires either two marked limitations across the four “paragraph B” domains, or one extreme limitation in a single domain.

Five-step disability evaluation

A sequential Social Security process that considers (1) work activity, (2) severity of impairments, (3) whether impairments meet/equal listed criteria, (4) ability to perform past work, and (5) ability to perform other work in the national economy.

Conclusion

The Seventh Circuit’s decision affirms that ALJs must correctly apply 20 C.F.R. § 404.1520c by articulating supportability and consistency—and it sharply criticizes reasoning that selectively discounts a medical opinion, mischaracterizes treatment as conservative, or treats pain’s mental effects as outside psychological expertise.

Yet the case’s lasting significance lies in its outcome-determinative harmless-error analysis: when the disputed medical opinion, even if fully credited, would establish at most one “marked” mental limitation and no second marked (or extreme) limitation is identified, remand may be denied because the regulatory framework would still compel the same non-disability result.
