Listing 12.07 in 2026: Somatic Symptom, Illness Anxiety, and Conversion Disorder SSDI Claims

By Anthony Albert, Benefits Research Director, Disability Exchange. Published June 27, 2026. Disability Exchange is privately owned and not affiliated with the SSA.

Somatic symptom disorder, illness anxiety disorder, and conversion disorder (functional neurological symptom disorder) are some of the toughest SSDI claims to win. The physical symptoms feel real to the claimant. The medical workup keeps coming back normal or near normal. The claimant gets bounced between primary care, neurology, gastroenterology, cardiology, and pain clinics. Doctors stop returning calls. Examiners read the file and assume the claimant is exaggerating. Listing 12.07 exists to push back on that assumption. SSA recognizes these conditions as real psychiatric disorders that can be disabling. The trick is building a file the examiner can actually score.

This page walks Listing 12.07 line by line. The three Paragraph A pathways. The four Paragraph B mental functioning areas. The reason 12.07 has no Paragraph C and what that means for your Step 5 strategy. The assessment instruments examiners trust. The treatment record that proves the disorder is being managed rather than ignored. And two worked Massachusetts and Florida cases that show how the listing applies in real life.

The Listing 12.07 Text Read Word by Word

Listing 12.07 reads: somatic symptom and related disorders (see 12.00B6), satisfied by A and B. There is no third pathway. You need Paragraph A plus Paragraph B. Period. The absence of Paragraph C is one of the most important features of this listing and it shapes the entire claim strategy.

Section 12.00B6 of the preamble tells you what category of disorder fits. The verbatim text reads: "These disorders are characterized by physical symptoms or deficits that are not intentionally produced or feigned, and that, following clinical investigation, cannot be fully explained by a general medical condition, another mental disorder, the direct effects of a substance, or a culturally sanctioned behavior or experience. These disorders may also be characterized by a preoccupation with having or acquiring a serious medical condition that has not been identified or diagnosed. Symptoms and signs may include, but are not limited to, pain and other abnormalities of sensation, gastrointestinal symptoms, fatigue, a high level of anxiety about personal health status, abnormal motor movement, pseudoseizures, and pseudoneurological symptoms, such as blindness or deafness."

That paragraph carries three pieces of legal weight. First, the symptoms cannot be intentionally produced. That distinguishes 12.07 from factitious disorder and from malingering. SSA examiners are trained to read for evidence of secondary gain, but the listing assumes good faith unless contradicted. Second, the symptoms cannot be fully explained by a general medical condition. That is the diagnostic gate. The medical chart needs to show a workup that ruled out organic causes. Third, the preamble names the categories explicitly: somatic symptom disorder, illness anxiety disorder, and conversion disorder. Pseudoseizures (psychogenic non-epileptic seizures, PNES) sit here too. Functional movement disorder sits here. Functional weakness sits here.

Paragraph A: Three Pathways, Pick One

Paragraph A requires medical documentation of one or more of the following:

Pathway 1: Symptoms of altered voluntary motor or sensory function that are not better explained by another medical or mental disorder. This is the conversion disorder pathway. Functional weakness, functional movement disorder, functional sensory loss (psychogenic blindness, deafness, anesthesia), pseudoseizures. The DSM-5-TR criterion is one or more symptoms of altered voluntary motor or sensory function, clinical findings provide evidence of incompatibility between the symptom and recognized neurological or medical conditions, and the symptom is not better explained by another medical or mental disorder. SSA mirrors the DSM-5-TR almost verbatim but adds the diagnostic gate language. The chart needs neurology workup that includes MRI, EEG (for PNES), nerve conduction studies if relevant, and clinical exam findings that affirmatively support a functional diagnosis. Hoover sign for functional leg weakness. Tremor entrainment for functional tremor. Video EEG for PNES. Without those rule-out findings, examiners discount the claim.

Pathway 2: One or more somatic symptoms that are distressing, with excessive thoughts, feelings, or behaviors related to the symptoms. This is the somatic symptom disorder pathway. DSM-5-TR Criterion A: one or more somatic symptoms that are distressing or result in significant disruption of daily life. Criterion B: excessive thoughts, feelings, or behaviors related to the somatic symptoms or associated health concerns as manifested by at least one of disproportionate and persistent thoughts about seriousness, persistently high anxiety about health or symptoms, or excessive time and energy devoted to symptoms or health concerns. Criterion C: persistent symptomatic state, typically more than 6 months.

Pathway 3: Preoccupation with having or acquiring a serious illness without significant symptoms present. This is the illness anxiety disorder pathway (formerly hypochondriasis). DSM-5-TR Criterion A: preoccupation with having or acquiring a serious illness. Criterion B: somatic symptoms are not present or, if present, are only mild in intensity. Criterion C: high level of anxiety about health and easily alarmed about personal health status. Criterion D: excessive health-related behaviors (repeated body checking) or maladaptive avoidance (avoiding medical appointments out of fear).

You need to satisfy one of the three pathways. Not all three. The chart should make clear which pathway the claim is built on. The pathway choice also shapes the medical evidence. Conversion disorder needs neurology rule-out. Somatic symptom disorder needs documentation of repeated normal workups across multiple specialties. Illness anxiety disorder needs documentation of the preoccupation pattern itself with limited or no genuine physical symptoms.

Paragraph B: Four Mental Functioning Areas

Paragraph B requires extreme limitation of one, or marked limitation of two, of the following areas of mental functioning. The four areas come from Section 12.00E and they are identical across every Section 12 listing. Understand, remember, or apply information. Interact with others. Concentrate, persist, or maintain pace. Adapt or manage oneself.

The first area, understand, remember, or apply information, is rarely the strongest area for somatic disorder claims. Most claimants have normal cognition on standard testing. The exception is somatic symptom disorder with cognitive complaints (sometimes called functional cognitive disorder). The claimant reports memory problems and word-finding difficulty. Neuropsychological testing shows variable effort patterns and inconsistent performance. The Test of Memory Malingering (TOMM) and Word Memory Test results need careful interpretation because functional cognitive disorder often produces failed effort indicators that look like malingering but reflect true cognitive disengagement under stress. The skilled neuropsychologist scores this differently.

The second area, interact with others, is often a strong area for somatic symptom disorder. The claimant avoids social settings because of pain, fatigue, or fear of symptoms recurring in public. Family relationships strain under the weight of repeated medical complaints and doctor shopping. Pseudoseizure patients often withdraw from school, work, and family events because they cannot predict when a seizure will occur. Conversion patients with functional weakness avoid public outings because mobility aids draw attention. The chart needs to document concrete examples of social withdrawal, conflict, or avoidance.

The third area, concentrate, persist, or maintain pace, is often the strongest area for these claims. Chronic pain interrupts concentration. Fatigue limits persistence. Symptom monitoring (constant body checking in illness anxiety disorder) destroys pace. Pseudoseizure unpredictability prevents sustained task completion. The chart needs to document specific functional examples. Cannot read for more than 10 minutes without losing place. Cannot complete a meal preparation task without sitting down to recover. Cannot follow a conversation because attention drifts to bodily sensations. Cannot complete paperwork because of intrusive worry about symptoms.

The fourth area, adapt or manage oneself, captures the broader functional collapse. Self-care declines because of pain or fatigue. Schedule keeping breaks down because of medical appointments and symptom flares. Stress tolerance is gone. Medication adherence is poor because of side effect intolerance or skepticism about psychiatric treatment. The chart needs examples of these specific deficits.

The 12.00F severity scale runs from none through mild, moderate, marked, to extreme. Marked means seriously limited functioning in a given area. Extreme means inability to function in that area on a sustained basis. A claimant who can leave the house twice a week with great difficulty is marked in adapt or manage oneself. A claimant who cannot leave the house at all without crisis-level distress is extreme.

Why 12.07 Has No Paragraph C and What It Means

Most Section 12 listings have a Paragraph C alternative for chronic, treatment-supported claims that fall just short of Paragraph B. Listing 12.04 (depressive and bipolar disorders) has one. Listing 12.06 (anxiety and OCD) has one. Listing 12.03 (schizophrenia spectrum) has one. Listing 12.15 (PTSD) has one. Listings 12.07 (somatic), 12.08 (personality), 12.10 (autism), 12.11 (neurodevelopmental), and 12.13 (eating disorders) do not.

The reason is policy choice. Paragraph C was designed for conditions where well-documented treatment can hold the claimant in a fragile equilibrium that breaks under added demand. SSA decided that somatic, personality, autism, neurodevelopmental, and eating disorders do not fit that profile as cleanly. The chronicity in 12.07 is captured by the DSM-5-TR 6-month criterion baked into Paragraph A. The functional impact has to be proved through Paragraph B without the safety net.

This matters for strategy. If your Paragraph B case is borderline (one marked area instead of two markeds, or two moderates instead of one extreme), you cannot win at Step 3. You have to drop down to Step 5 and win on residual functional capacity. The mental RFC for a 12.07 claim that falls short of Step 3 should reflect specific functional limitations: off-task percentage (often 20 to 25 percent because of pain or symptom intrusion), absences per month (often 3 to 4 because of medical appointments and flares), and inability to sustain even simple, routine, repetitive tasks for an 8-hour workday. SSR 85-15 lets a VE testify that those limitations preclude competitive employment.

Assessment Instruments SSA Examiners Trust

The assessment battery for a 12.07 claim should include both somatic symptom severity scales and general psychiatric measures. The Patient Health Questionnaire 15 (PHQ-15) scores somatic symptom severity from 0 to 30. A score of 15 or higher reflects severe somatic symptoms. The Somatic Symptom Scale 8 (SSS-8) is a short version that scores from 0 to 32, with 12 or higher indicating very high severity. The Whiteley Index 14 scores illness anxiety with a cutoff of 8 to 10 for clinical concern. The Health Anxiety Questionnaire scores the cognitive, behavioral, and affective components of illness anxiety.

For conversion disorder, the chart needs the structured neurological exam findings that confirm functional diagnosis. Hoover sign (positive when contralateral hip extension returns during contralateral hip flexion). Tremor entrainment (positive when functional tremor changes frequency to match a voluntary task). Give-way weakness. Inconsistent visual field defects. For pseudoseizures, the gold standard is video EEG capturing a typical event without ictal EEG changes. SSA examiners specifically look for video EEG documentation in PNES claims.

General psychiatric measures add weight. PHQ-9 for depression overlay (which is common). GAD-7 for anxiety overlay. PCL-5 for PTSD overlay (also common, especially in conversion disorder where past trauma is a strong risk factor). MMPI-2-RF can be useful but interpretation requires a skilled psychologist. The Restructured Clinical Scales (RC1 Somatic Complaints, RC2 Low Positive Emotions, RC7 Dysfunctional Negative Emotions) tend to be elevated in genuine somatic symptom disorder, but the Validity Scales (F-r, Fp-r, Fs, FBS-r, RBS) need careful interpretation because somatic disorder patients often produce elevated F-r and Fs scores that look like over-reporting but reflect genuine symptom intensity.

The Treatment Record That Wins

Examiners want to see that the claimant is engaged in psychiatric or psychological treatment specific to the somatic disorder. Treatment as usual for somatic symptom disorder includes cognitive behavioral therapy targeting symptom appraisal and health behaviors. The standard CBT-SS protocols run 12 to 16 sessions and target catastrophic thinking, body vigilance, and avoidance behaviors. Mindfulness-based therapy has growing evidence. Acceptance and Commitment Therapy works for chronic pain overlay. Trauma-focused therapy matters for conversion disorder cases where past trauma is documented.

Pharmacologic treatment for somatic symptom disorder relies on SSRIs and SNRIs, even though no medication is FDA approved specifically for the disorder. Sertraline 50 to 200 mg, fluoxetine 20 to 60 mg, escitalopram 10 to 20 mg, and duloxetine 30 to 120 mg are common choices. Duloxetine pulls double duty for somatic disorder with chronic pain. Mirtazapine 15 to 45 mg is used when sleep and appetite are also affected. Pregabalin and gabapentin are used off-label for pain components. The chart should show medication trials of adequate dose and duration, not just one-shot prescriptions.

For conversion disorder, physical therapy is a recognized treatment. Specialized FND physical therapy programs (like those described by the Stone and Edwards groups) use distraction-based retraining and motor reprogramming. The chart should document referral to and participation in this kind of program. For pseudoseizures, the standard approach is psychiatric or psychological treatment paired with antiepileptic taper if the patient was wrongly placed on AEDs. Discontinuation of unnecessary AEDs is itself a treatment marker that the diagnosis is being managed correctly.

Examiners also look for what the chart does not show. They look for absence of evidence of malingering. They look for absence of evidence of factitious disorder (no fabrication, no medication tampering, no induction of symptoms). They look for cooperation with treatment (attendance at therapy, medication adherence, willingness to taper unnecessary medications). They look for absence of egregious doctor-shopping or hospital-shopping unless it is documented as a feature of the disorder itself.

Worked Example: Maria, 44, Worcester, Massachusetts, Conversion Disorder

Maria worked as a unit secretary at UMass Memorial Hospital for 14 years. In May 2023 she developed sudden left leg weakness after witnessing a code blue. She was admitted to the neurology service. MRI brain and spine were normal. EMG and nerve conduction were normal. Hoover sign was positive. Diagnosis: functional neurological symptom disorder, weakness subtype. She was discharged to outpatient FND physical therapy and to psychiatry.

Over the next 18 months Maria developed additional symptoms. Functional tremor in the left arm. Three pseudoseizure events with normal video EEG during a 5-day epilepsy monitoring unit admission at UMass in October 2024. Right-sided sensory loss with non-anatomic distribution. She filed for SSDI in March 2025. Initial denial. Reconsideration denial. ALJ hearing scheduled for September 2026.

Her treatment record by the hearing showed 24 months of weekly individual psychotherapy with a clinical psychologist, 8 months of trauma-focused CBT addressing past childhood medical trauma (multiple surgeries for cleft palate repair between ages 2 and 14), four 12-week FND physical therapy cycles, sertraline titrated to 150 mg with partial response, and gabapentin 900 mg daily for pain overlay. She had also completed a 4-week intensive outpatient program at Spaulding Rehabilitation Hospital in Boston for functional neurological disorders.

Her 12.07 analysis. Paragraph A1 satisfied. Conversion disorder with positive Hoover sign, normal MRI and EMG, captured pseudoseizures on video EEG without ictal changes. The diagnostic gate cleared on objective evidence.

Paragraph B analysis. Understand, remember, or apply information: moderate. Cognitive testing showed mild attention and processing speed deficits but no major impairment. Interact with others: marked. Maria had withdrawn from her church choir, stopped attending family gatherings because of unpredictable pseudoseizures, and had three documented arguments with her husband over symptom severity. Concentrate, persist, or maintain pace: marked. She could not complete a 30-minute task without symptom intrusion, could not read for more than 15 minutes, and could not sustain pace at simple household tasks. Adapt or manage oneself: marked. She could not leave the house alone, could not drive, required her husband to accompany her to all medical appointments after a pseudoseizure in a parking lot, and had developed avoidance behaviors around any setting that resembled the hospital where her symptoms started.

Three markeds plus a moderate. Paragraph B satisfied with two markeds. Maria's file met Listing 12.07 at the ALJ level. The treating psychologist's HA-1152 statement, the video EEG documentation, and the longitudinal physical therapy record carried the case. See the Massachusetts state page for SSDI and SSI numbers.

Worked Example: Eric, 37, Tampa, Florida, Illness Anxiety Disorder

Eric worked as an IT support analyst at a Tampa hospital system. After his father died of pancreatic cancer in 2022, Eric became preoccupied with the idea that he had cancer. Over the next 18 months he saw his primary care physician 47 times, requested 14 different imaging studies, scheduled 6 colonoscopies (two were performed, both normal), demanded 4 endoscopies (two performed, both normal), and had 23 different blood test panels including 8 tumor marker panels. All workups were negative or showed clinically insignificant findings.

His primary care office eventually invoked their patient agreement policy and limited him to one visit per month. Eric began seeking care at urgent care centers and emergency departments. He was seen at Tampa General Hospital ED 19 times in 2024 for various symptom complaints. He scheduled multiple second opinions across the Tampa Bay area and accumulated bills exceeding $80,000 in out-of-pocket costs even with employer insurance.

Eric was let go from his IT job in November 2024 after using 78 sick days in a calendar year. He filed for SSDI in February 2025. Denied at initial. Denied at reconsideration. ALJ hearing in October 2026.

By the hearing, Eric had been in treatment with a psychiatrist for 14 months. Diagnosis: illness anxiety disorder, care-seeking type, with comorbid generalized anxiety disorder. He had failed two SSRI trials due to side effect catastrophizing. He was now stable on fluoxetine 40 mg paired with cognitive behavioral therapy for health anxiety. He attended weekly therapy with a clinical psychologist trained in the Salkovskis cognitive model for health anxiety. The Whiteley Index 14 score at intake was 12, dropped to 9 after one year of treatment. PHQ-15 was 18 at intake, 14 at the year mark.

The 12.07 analysis. Paragraph A3 satisfied. Preoccupation with having or acquiring a serious illness without significant symptoms present. The diagnostic gate cleared on the documented pattern of repeated normal workups and the clinical diagnosis from a board-certified psychiatrist.

Paragraph B analysis. Understand, remember, or apply information: moderate. Cognitive testing was normal. The deficit was attentional, not cognitive. Interact with others: marked. Eric had alienated his primary care office, his family avoided his calls because of constant health discussions, and his marriage was in crisis with documented couples therapy notes from his psychologist. Concentrate, persist, or maintain pace: extreme. Eric spent an estimated 6 to 8 hours per day on health-related behaviors. Symptom checking, internet searches, scheduling appointments, calling insurance, requesting records. He could not sustain attention to work tasks. Adapt or manage oneself: marked. He could not adapt his routine to limit health behaviors despite cognitive understanding that the behaviors were harmful. He had repeated decompensations during attempted treatment phases, including one Baker Act commitment in March 2025 after a panic attack in the ED.

One extreme plus two markeds. Paragraph B satisfied. Eric's file met Listing 12.07 at the ALJ level. The detailed psychiatric record, the Whiteley Index documentation, and the treating psychiatrist's HA-1152 statement that mapped each B area to specific clinical examples carried the case. See the Florida state page for SSDI and SSI numbers.

How To Build the 12.07 File That Wins

The file that wins at Step 3 has six components. First, a confirmed psychiatric or psychological diagnosis from a board-certified psychiatrist, psychologist, or neuropsychiatrist. Primary care diagnoses are weaker. The diagnosis needs to specify the subtype (somatic symptom disorder, illness anxiety disorder, conversion disorder with specific symptom type, or PNES). Second, the medical workup that ruled out organic causes. For conversion disorder, this means neurology workup with rule-out imaging and clinical exam findings that affirmatively support functional diagnosis. For PNES, video EEG. For somatic symptom disorder, the chart should document the multispecialty workup history. For illness anxiety disorder, the chart should document the pattern of repeated negative workups. Third, standardized assessment scores. PHQ-15 or SSS-8 for somatic severity. Whiteley Index or HAQ for illness anxiety. PHQ-9 and GAD-7 for comorbid depression and anxiety. PCL-5 for trauma overlay.

Fourth, a treatment record showing engagement with psychiatric or psychological care. Medication trials of adequate dose and duration. Therapy attendance with frequency and modality. Documented response or non-response. Fifth, function reports from the claimant and at least one third party (spouse, sibling, adult child, or close friend) that map specific functional examples to the four B areas. Sixth, a treating source statement on form HA-1152 from the psychiatrist or psychologist that scores each B area as marked or extreme with specific clinical examples drawn from progress notes.

The treating source statement carries the most weight. SSA 20 CFR 404.1520c requires examiners to evaluate persuasiveness on supportability and consistency. A statement that quotes the 12.00E language, references assessment scores, and ties them to functional examples from progress notes is the most persuasive evidence in the file. A box-checked generic form is almost worthless. The strongest statements include 2 or 3 paragraphs per B area with specific incidents, dates, and clinical observations.

What To Do If You Lose at the Initial Level

The reconsideration step rarely changes the outcome on 12.07 files. The ALJ hearing is where these cases get fixed. Three moves matter. First, obtain updated standardized assessments (PHQ-15, SSS-8, Whiteley Index, PHQ-9, GAD-7) within 90 days of the hearing. Second, obtain a treating source statement that explicitly maps each B area to the 12.00E language and the 12.00F severity scale with clinical examples. Third, consider requesting a medical expert at the hearing. The medical expert is appointed by the ALJ and is typically a board-certified psychiatrist or psychologist who can testify on whether the listing is met or, if not met, what mental RFC limitations apply at Step 5.

If Step 3 fails, the Step 5 RFC analysis is where you win. The mental RFC should reflect specific limitations: off-task 20 to 25 percent of the workday because of symptom intrusion, absences of 3 to 4 days per month because of medical appointments and flares, inability to maintain pace at even simple routine repetitive tasks for 8 hours, and inability to interact with the public or coworkers on a sustained basis. The vocational expert will testify that those limitations preclude competitive employment. SSR 85-15 supports this analysis.

Massachusetts ALJ hearings are heard at the Boston OHO and the Lawrence OHO. Average wait at filing through hearing decision is 14 to 16 months in 2026. Florida ALJ hearings are heard at the Orlando, Miami, Tampa, Fort Lauderdale, and Jacksonville OHOs. Average wait is 12 to 14 months. Hearing-level allowance rates for somatic disorder cases vary widely by hearing office but cluster around 38 to 45 percent for well-developed files. Properly developed 12.07 claims that combine strong Paragraph A documentation, standardized assessments, and a detailed treating source statement push allowance rates closer to 55 to 60 percent.

Related deep dives that cross-reference 12.07: Listing 12.06 anxiety and OCD for the anxiety overlay that often coexists with somatic and illness anxiety disorders, Listing 12.04 depressive and bipolar disorders for the depression overlay common in chronic somatic disorder, and Listing 12.15 PTSD and trauma related disorders for the trauma history that is a strong risk factor for conversion disorder and PNES.
