How SSA Evaluates ILD and Pulmonary Fibrosis Under Blue Book §3.02 and Related Listings

Pulmonary fibrosis and interstitial lung disease (ILD) are among the most serious respiratory disorders evaluated by the Social Security Administration (SSA). These conditions cause scarring and inflammation in the lungs, making it increasingly difficult for oxygen to pass into the bloodstream. Over time, even simple activities—walking across a room, climbing stairs, or carrying light objects—can become exhausting.

For many Texans, ILD and pulmonary fibrosis lead to severe breathing limitations, chronic fatigue, and reduced stamina that make full‑time work impossible. If you are struggling with these conditions, you may qualify for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI).

At MLF Legal, our Texas social security disability lawyers help people gather the right medical evidence, document their symptoms, and build strong interstitial lung disease, pulmonary fibrosis and social security disability claims.

Understanding Pulmonary Fibrosis & Interstitial Lung Disease

Pulmonary fibrosis and ILD refer to a group of disorders that cause scarring (fibrosis) and inflammation in the lungs. This scarring stiffens the lung tissue, making it difficult to inhale fully and reducing the lungs’ ability to transfer oxygen into the bloodstream.

Common types of ILD include:

  • Idiopathic pulmonary fibrosis (IPF)

  • Hypersensitivity pneumonitis

  • Sarcoidosis with lung involvement

  • Autoimmune‑related ILD (lupus, rheumatoid arthritis, scleroderma)

  • Occupational lung disease (asbestosis, silicosis)

  • Drug‑induced lung disease

  • Radiation‑induced fibrosis

Common symptoms include:

  • Shortness of breath

  • Dry, persistent cough

  • Fatigue

  • Chest discomfort

  • Reduced exercise tolerance

  • Low oxygen levels

  • Clubbing of the fingers (in advanced cases)

These symptoms often worsen over time, making daily activities and work increasingly difficult.

How SSA Evaluates Pulmonary Fibrosis & ILD Under Listing 3.02

Pulmonary fibrosis and social security disability claims are primarily evaluated under Blue Book Listing 3.02 – Chronic Respiratory Disorders, which focuses on objective medical testing.

1. DLCO Testing (Diffusing Capacity of the Lungs for Carbon Monoxide)

This is the most important test for ILD claims. A low DLCO indicates impaired gas exchange and may meet Listing 3.02B.

2. Spirometry (FEV1 and FVC)

Measures airflow and lung volume. Reduced values may support Listing 3.02A.

3. Arterial Blood Gas (ABG) Testing

Evaluates oxygen and carbon dioxide levels. Low oxygen levels may support disability.

4. Pulse Oximetry

Shows oxygen saturation at rest and during exertion.

5. Imaging

High‑resolution CT (HRCT) scans are critical for diagnosing ILD and showing the extent of fibrosis.

6. 6‑Minute Walk Test (6MWT)

Shows how exertion affects oxygen levels and stamina.

7. Hospitalizations & Exacerbations

SSA reviews:

  • ER visits

  • Inpatient stays

  • Exacerbations requiring steroids or oxygen therapy

FAQs About Pulmonary Fibrosis & ILD Social Security Disability Benefits

Does pulmonary fibrosis automatically qualify for disability?

Not automatically. You must show that your condition meets Listing 3.02 or prevents you from sustaining full‑time work through RFC limitations.

DLCO testing, HRCT scans, spirometry, ABG studies, and 6‑minute walk tests are key.

Yes. The need for supplemental oxygen is strong evidence of severe respiratory impairment and often supports disability approval.

SSA reviews ER visits, hospitalizations, and exacerbations requiring steroids or oxygen therapy. Frequent flare‑ups strengthen your claim.

Yes. ILD caused by lupus, rheumatoid arthritis, scleroderma, or other autoimmune diseases may qualify under respiratory or autoimmune listings.

A lawyer helps gather medical evidence, coordinate with your pulmonologist, prepare RFC documentation, and appeal denials.

Pulmonary Fibrosis and Social Security Disability

Do You Need to Meet Listing 3.02 to Qualify?

No. Many ILD and pulmonary fibrosis and social security disability claimants are approved through Residual Functional Capacity (RFC) instead of meeting the listing.

You may qualify if your condition prevents you from:

  • Walking more than short distances

  • Standing for long periods

  • Lifting or carrying objects

  • Working around dust, fumes, smoke, or chemicals

  • Maintaining a full‑time schedule

  • Performing your past work or adjusting to new work

Even if your test results do not meet SSA’s exact thresholds, your symptoms and limitations may still support disability.  The SSA evaluates these cases under the sequential evaluation process.

How Pulmonary Fibrosis & ILD Limit Work Ability

ILD and pulmonary fibrosis affect both physical and environmental work functions.

Physical limitations include:

  • Shortness of breath with minimal exertion

  • Reduced stamina

  • Difficulty lifting or carrying

  • Needing frequent breaks

  • Inability to walk long distances or climb stairs

Environmental limitations include:

  • Inability to tolerate dust, fumes, smoke, or chemicals

  • Sensitivity to temperature extremes

  • Difficulty working outdoors or in poorly ventilated areas

Attendance issues:

  • Frequent medical appointments

  • Exacerbations requiring rest

  • Hospitalizations

These limitations often make full‑time work unsustainable.
