Also called CF, mucoviscidosis (CF).
Cystic fibrosis can support SSDI or SSI when pulmonary findings meet Listing 3.04, after a qualifying lung transplant, or when residual lung, nutrition, and treatment limits rule out sustained work. A positive newborn screen, a CFTR mutation report, or modulator therapy is not an approval. SSA needs current respiratory evidence matching the listing’s measurement rules.
What is Cystic Fibrosis?
NHLBI describes cystic fibrosis as a genetic disorder affecting salt and water transport, with thick mucus in the lungs, pancreas, and other organs. Adults may have recurrent lung infections, bronchiectasis, pancreatic insufficiency, CF-related diabetes, sinus disease, and liver involvement. CFTR modulators have changed the course for many people, but they do not erase the need for objective pulmonary evidence in a disability claim.
Common symptoms of Cystic Fibrosis
- Chronic cough, sputum, or recurrent lung infections
- Shortness of breath and reduced exercise tolerance
- Difficulty maintaining weight or pancreatic enzyme dependence
- CF-related diabetes in some adults
- Sinus disease or liver complications in some people
How can Cystic Fibrosis affect a person’s ability to work?
- Absences for IV antibiotics, hospitalizations, or clinic airway-clearance time
- Reduced standing, walking, and environmental exposure to dust or fumes
- Fatigue and off-task time during pulmonary exacerbations
- Nutrition, enzyme, and insulin management during a workday
- Infection risk around ill coworkers during exacerbations
Does Social Security have a Listing for Cystic Fibrosis?
Social Security currently has listing criteria that may apply: 3.04 (Cystic fibrosis); 3.11 (Lung transplantation). Meeting a listing requires the specific medical findings in that listing, not only the diagnosis.
Listing 3.04 requires CF documented as described in 3.00J2, plus paragraph A through G. 3.04A uses FEV1 at or below the official Table VII values for age, gender, and height. 3.04B is three hospitalizations for exacerbations or complications within 12 months, at least 30 days apart. 3.04C is spontaneous pneumothorax requiring a chest tube. 3.04D is respiratory failure requiring invasive ventilation, BiPAP, or both for specified continuous periods. 3.04E is pulmonary hemorrhage requiring vascular embolization. 3.04F is specified pulse-oximetry values twice in 12 months. 3.04G requires two listed exacerbations or complications in 12 months (IV antibiotics, hospitalized pulmonary hemorrhage, specified nutrition support, or CFRD requiring daily insulin for at least 90 consecutive days). Pancreatic or hepatobiliary CF complications may also be evaluated under 5.00. Listing 3.11 considers disability for three years after lung transplant. This page does not copy FEV1 or SpO2 tables; the official listing controls.
SSA first confirms CF under 3.00J2 (typically clinical plus laboratory or genetic evidence). Listing 3.04 is then applied to spirometry, hospitalizations, or the other listed complications. If 3.04 is not met, digestive or endocrine complications may still meet 5.00 or be assessed in RFC. Lung transplant follows 3.11. Modulator therapy is relevant to current function; it is not a separate listing.
Can you qualify if you do not meet an SSA Listing?
Yes. CF that misses a 3.04 paragraph may still preclude work through combined pulmonary, digestive, and endocrine RFC.
What medical evidence may help document Cystic Fibrosis?
- CF-clinic records documenting the diagnosis under 3.00J2
- Spirometry performed to listing testing standards
- Hospitalization and IV-antibiotic timelines
- Pulse-oximetry reports that meet 3.00H when 3.04F is considered
- Nutrition, CFRD, and hepatobiliary records
Testing, imaging, and laboratory studies
- FEV1 compared with official Table VII, not an informal percent-predicted cutoff invented here
- Pulse oximetry compared with official Table VIII when 3.04F is used
- Sweat chloride or CFTR genetics as part of establishing CF
- Sputum cultures and imaging as used clinically
Airway clearance, inhaled antibiotics, modulators, enzymes, and insulin should be dated with response. A person who is stable on modulators may still meet 3.04 if spirometry or complications match the listing.
How SSA may evaluate residual functional capacity
Daily airway-clearance time, frequent clinic visits, and exacerbation recovery often drive RFC when 3.04 is not met.
Exertional limits usually follow lung function, nutrition, and CFRD. Environmental restrictions should track treating-source advice.
Common issues that can weaken a disability claim involving Cystic Fibrosis
Submitting only a genetic report; using a hospital FEV1 during an exacerbation as if it were listing-stable spirometry; or calling all CF a CAL condition.
What may strengthen the medical documentation
Listing-compliant spirometry, a hospitalization calendar, and CF-clinic notes covering lungs, nutrition, and CFRD.
Cystic Fibrosis and related medical conditions
- Asthma — Asthma causes variable airway inflammation and narrowing. Current Listing 3.03 requires both qualifying pulmonary-function results and the specified hospitalization history.
- Chronic Liver Disease — Listing 5.05 evaluates chronic liver disease by documented complications such as variceal bleeding, ascites, peritonitis, hepatorenal or hepatopulmonary syndrome, encephalopathy, or specified SSA CLD scores. A cirrhosis label is not an approval.
- Chronic Obstructive Pulmonary Disease — COPD causes persistent airflow obstruction. Listing 3.02 uses standardized respiratory testing; claims below listing level may still turn on exertion, exposure, and exacerbations.
- Diabetes — Diabetes has no standalone adult listing. SSA evaluates its documented effects on other body systems and the combined functional limits those complications cause.
- Sleep Apnea — Sleep apnea has no dedicated adult listing. SSA evaluates the medically documented sleep disorder and daytime limits—and any listing-level heart, lung, or neurologic complications—rather than an AHI number alone.
How Brock & Stout may help
We compare CF-clinic evidence with Listing 3.04, gather digestive and diabetes records when relevant, and develop RFC for residual disease. Representation cannot guarantee approval.
Frequently asked questions
Cystic fibrosis is not treated as a named CAL condition on SSA’s current list. Adult claims are evaluated under Listing 3.04, related digestive listings when those criteria are met, and residual functional capacity.
No. SSA looks at current spirometry, exacerbations, and complications. Improvement on modulators is relevant, but it does not replace the official 3.04 criteria.
