Chronic Fatigue Syndrome and SSDI Under SSR 14-1p

Chronic fatigue syndrome (CFS) can qualify for Social Security Disability Insurance (SSDI), but only after the Social Security Administration (SSA) finds an objective abnormality in the medical record. Social Security Ruling (SSR) 14-1p, effective April 3, 2014, lists the medical signs and laboratory findings SSA accepts before it will evaluate how disabling the fatigue actually is.

SSR 14-1p rescinded and replaced the older SSR 99-2p, and it governs claims under both title II and title XVI as well as continuing disability reviews. The ruling treats myalgic encephalomyelitis (ME) as a subtype of CFS, so claimants whose records use the terms ME, CFS, or ME/CFS are evaluated under the same policy.

The Core Rule: Signs or Laboratory Findings First

SSR 14-1p states that CFS constitutes a medically determinable impairment (MDI) when it is accompanied by medical signs or laboratory findings. This threshold matters more in a CFS claim than in almost any other type of claim.

The Social Security Act and SSA's regulations require that an impairment result from anatomical, physiological, or psychological abnormalities shown by medically acceptable clinical and laboratory diagnostic techniques, as set out in 20 CFR 404.1508 and 404.1521. A claimant may not be found disabled based on a statement of symptoms alone. Fatigue, no matter how real, is a symptom.

SSA also acknowledges the diagnostic problem directly. SSR 14-1p notes that there is no single definitive laboratory test for CFS and that standard laboratory results in the normal range are characteristic of many people with CFS. Those normal results should not be relied upon to the exclusion of all other clinical evidence when SSA decides whether the impairment exists.

Who Can Establish the Diagnosis

Under SSR 14-1p, a licensed physician (a medical or osteopathic doctor) is the only acceptable medical source who can provide evidence to establish an MDI of CFS. The physician's diagnosis, by itself, is not enough.

The evidence must document that the physician reviewed the person's medical history and conducted a physical examination. SSA then reads the treatment notes to see whether they are consistent with the diagnosis, whether symptoms have improved, worsened, or stayed stable, and what the physician concluded about physical strength and functional ability.

Other acceptable medical sources, such as licensed psychologists, still matter. SSR 14-1p explains that SSA may request evidence from them to identify other impairments and to evaluate the severity and functional effects of CFS. Evidence from nonmedical sources, including family members, former employers, and teachers, can help show day-to-day function over time.

The Medical Signs SSA Accepts

SSR 14-1p requires that qualifying medical signs be clinically documented over a period of at least 6 consecutive months. The signs listed in the ruling are:

• Palpably swollen or tender lymph nodes on physical examination
• Nonexudative pharyngitis, meaning a persistent sore, red throat without discharge
• Persistent, reproducible muscle tenderness on repeated examinations, including positive tender points
• Any other medical signs consistent with medically accepted clinical practice and with the rest of the record

For that final catchall category, the ruling points to signs described in the Canadian Consensus Criteria and the International Consensus Criteria, such as frequent viral infections with prolonged recovery, sinusitis, ataxia, extreme pallor, and pronounced weight change.

Tender points deserve a special note. SSR 14-1p explains that a person with CFS who also has tender points has an MDI even if the count falls short of the American College of Rheumatology criteria for fibromyalgia under SSR 12-2p.

The Laboratory Findings SSA Accepts

SSR 14-1p identifies a short list of laboratory findings that establish the impairment:

• An elevated antibody titer to Epstein-Barr virus (EBV) capsid antigen equal to or greater than 1:5120, or early antigen equal to or greater than 1:640
• An abnormal magnetic resonance imaging (MRI) brain scan
• Neurally mediated hypotension as shown by tilt table testing or another clinically accepted form of testing
• Other laboratory findings consistent with medically accepted clinical practice and with the rest of the record, for example an abnormal exercise stress test or abnormal sleep studies

The list is expressly not all-inclusive. Because research into CFS continues, SSA may accept signs and findings that are not on the list as long as they are consistent with accepted clinical practice and the other evidence.

Cognitive Symptoms Can Be Evidence Too

Many people with CFS report problems with short-term memory, information processing, visual-spatial function, comprehension, concentration, speech, word-finding, and calculation. SSR 14-1p addresses these neurocognitive complaints directly.

When deficits in these areas are documented by a mental status examination or psychological testing, the findings may constitute medical signs or, in the case of psychological testing, laboratory findings that establish the presence of an MDI. This is one of the most underused tools in a CFS claim, because a treating physician who notes only "memory complaints" produces a symptom, while one who documents abnormal mental status testing produces a sign.

The CDC Case Definition SSA Borrowed From

SSR 14-1p adopts the framework of the 1994 case definition developed by an international panel convened by the Centers for Disease Control and Prevention. Under that definition, the fatigue must be clinically evaluated, persistent or relapsing, and present for 6 months or more, and it must have a new or definite onset, remain unexplained by another physical or mental disorder, not result from ongoing exertion, not be substantially alleviated by rest, and cause a substantial reduction in previous levels of occupational, educational, social, or personal activity.

The definition also requires at least 4 of the following symptoms persisting or recurring during 6 or more consecutive months of illness, none of them predating the fatigue:

• Postexertional malaise lasting more than 24 hours
• Impaired short-term memory or concentration severe enough to cause a substantial reduction in activity
• Sore throat
• Tender cervical or axillary lymph nodes
• Muscle pain
• Multi-joint pain without joint swelling or redness
• Headaches of a new type, pattern, or severity
• Waking unrefreshed

A physician can make the clinical diagnosis from reported symptoms after ruling out other causes. SSA still needs its own objective evidence before the impairment counts for disability purposes.

What Happens After the Impairment Is Established

Once an MDI of CFS exists, SSA runs the standard five-step sequential evaluation. At step 2 the impairment must have lasted or be expected to last 12 continuous months under 20 CFR 404.1509, and symptoms must have more than a minimal effect on basic work activities.

At step 3, CFS has no listing of its own. SSR 14-1p states that SSA cannot find a person with CFS alone meets a listing, but it must compare the specific findings to pertinent listings for medical equivalence. The ruling's own example is listing 14.06B, and it directs adjudicators to the mental disorders listings when psychological manifestations are present.

At steps 4 and 5, SSA assesses residual functional capacity (RFC) under 20 CFR 404.1545, which defines what the person can still do despite the limitations. Statements about symptoms are then evaluated under the two-step process in 20 CFR 404.1529. Note that SSR 14-1p still cites the older credibility rule, SSR 96-7p, which SSA rescinded in 2016 with SSR 16-3p. The current approach looks at how consistent your statements are with the whole record rather than at a credibility judgment.

Building the Record

SSR 14-1p asks for longitudinal evidence because CFS signs and symptoms fluctuate. Records covering treatment, response to treatment, and a detailed description of functional limits over many months carry more weight than a single visit. SSA generally requests evidence from medical sources for the 12 months preceding the month of application.

If the evidence is insufficient, SSR 14-1p permits SSA to recontact treating sources, request additional existing records, ask the claimant for more information, or purchase a consultative examination at SSA expense. Finally, co-occurring conditions common in CFS, including fibromyalgia, irritable bowel syndrome, migraines, and Sjogren's syndrome, are considered together with CFS under the combined effects rule in 20 CFR 404.1523.

Frequently Asked Questions

Can you get SSDI for chronic fatigue syndrome? Yes, but only after SSA confirms a medically determinable impairment. SSR 14-1p requires objective medical signs or laboratory findings, such as tender lymph nodes or an abnormal brain MRI, before severity is even evaluated.

Does a CFS diagnosis from my doctor prove the impairment for SSA? No. SSR 14-1p states that SSA cannot rely on a physician's diagnosis alone, and a statement of symptoms alone can never establish disability under the law.

Which laboratory findings count under SSR 14-1p? SSR 14-1p lists an elevated Epstein-Barr virus capsid antigen titer of 1:5120 or higher, or early antigen of 1:640 or higher, an abnormal brain MRI, and neurally mediated hypotension on tilt table testing.
