What is the SSA Blue Book?

Key takeaways

• The Social Security Administration's Blue Book breaks down the SSA’s disability criteria for physical and mental conditions considered severe enough to prevent an adult from performing substantial gainful activity.

• If your condition meets or equals a Blue Book listing, the SSA will generally consider you disabled for SSDI or SSI, as long as you also meet the program's non-medical rules.

• If your condition isn't listed, or doesn't fully meet a listing, you may still qualify by showing that your limitations keep you from working.

• The Blue Book covers both physical and mental health conditions, organized by body system.

The SSA Blue Book is a valuable guide that outlines the medical conditions Social Security uses to evaluate disability benefits claims. It’s a great starting point for anyone applying for SSDI or SSI and can help you better understand the qualifications and medical evidence Social Security looks for.

In this guide, we’ll break down how the SSA Blue Book works, which conditions it covers, and how you can use it to build a stronger disability application.

What is the SSA Blue Book?

The Blue Book is a nickname for a document created by the SSA. Its official title is Disability Evaluation Under Social Security. 

The Social Security Disability Blue Book explains how the SSA’s disability criteria work. It includes a “Listing of Impairments” that covers the conditions that qualify for SSDI and SSI. These listings explain how the SSA defines your medical eligibility for benefits. Each listing includes information on health records or tests that help prove your condition is sufficiently disabling. 

The Blue Book contains many different conditions, ranging from epilepsy to kidney disease to obsessive-compulsive disorders and more. However, the SSA is slow to update the Blue Book, so it doesn’t cover every condition that can qualify you for disability. For example, “long COVID” is not in the Blue Book even though it can qualify for disability.

In addition to the Blue Book, the SSA also has a resource called the Red Book. This book (available online as a PDF or in print) provides information on income requirements and employment opportunities for people with disabilities. 

Is there an SSA Blue Book PDF?

The SSA does not offer a downloadable PDF of the SSA Blue Book. But you can view and print the various sections on the Disability Evaluation Under Social Security page.

How the Blue Book listings are organized by bodily system

If you’re wondering whether your condition will qualify for disability benefits, the Social Security Blue Book can be a helpful place to start. Remember, the SSA considers each disability application on a case-by-case basis — but the Blue Book is still a good resource for disability applicants.

#1. Musculoskeletal Disorders

Musculoskeletal disorders affect the bones, joints, muscles, and connective tissues, and this section of the Blue Book also covers orthopedic conditions. These disorders often cause chronic pain and make it hard to walk, stand, lift, or use your hands. According to the SSA's most recent data, they're the most common reason people receive SSDI, accounting for about 34% of disabled workers getting benefits at the end of 2024.

You might fall into this Blue Book category if you live with pain and limited mobility symptoms that prevent you from performing basic daily tasks (or make those tasks difficult). If you struggle to walk, stand, sit, or pick up or lift items, finding a job that works for you can be difficult. 

#2. Special Senses and Speech

The Blue Book's section on special senses and speech covers conditions like vision loss, hearing loss, and trouble speaking. To meet the SSA's listing for vision loss, you'll generally need to meet one of these criteria:

• “Central visual acuity of 20/200 or less in the better eye with the use of a correcting lens. We use your best-corrected central visual acuity for distance in the better eye when we determine if this definition is met.”

• “An eye that has a visual field limitation such that the widest diameter of the visual field subtends an angle no greater than 20 degrees is considered as having a central visual acuity of 20/200 or less.”

People with hearing loss can meet the Blue Book listing in a few ways. If you've had cochlear implant surgery, the SSA considers you disabled for one year after the implant. After that, you can still qualify if tests show you have serious trouble understanding speech. If you don't have implants, you'll need medical records showing your hearing test results, such as audiometry and word recognition tests.

This category also covers conditions beyond vision and hearing loss, including loss of speech, which means being unable to speak in a way others can hear, understand, or keep up with.

#3. Respiratory Disorders

Respiratory conditions like asthma, cystic fibrosis, or sleep apnea can qualify you for disability if they prevent you from working. In general, applicants with respiratory disorders must meet at least some of the following criteria:

• You’ve been hospitalized multiple times.

• You are seeing a pulmonologist.

• You require the use of oxygen.

• You have testing that shows airflow obstruction.

• You’ve had recent respiratory failure.

Respiratory disorders like COPD, asthma, and cystic fibrosis can range from mild to severe. Whether yours qualifies usually depends on test results, like lung function tests, and how often you need hospital care. If you're not sure where you stand, check the SSA's Blue Book listing for respiratory disorders or talk with a disability lawyer.

#4. Cardiovascular System

According to the SSA, a cardiovascular impairment is any condition that affects how your heart or circulatory system works. That includes your heart, arteries, veins, capillaries, and lymphatic system. Common examples include heart failure, coronary artery disease, and irregular heart rhythms.

To qualify for disability based on a heart or circulatory issue, you’ll likely need to have at least one of the following:

• Central cyanosis

• Chronic heart failure or ventricular dysfunction

• Discomfort or pain due to myocardial ischemia

• Inadequate cardiac output

• Pulmonary vascular disease

• Syncope or near syncope

Plus, some or most of the following likely need to apply to you:

• You become winded or feel breathless after any activity.

• You experience leg swelling.

• You experience lightheadedness, chest pain, palpitation, or fatigue.

• You’ve undergone a stress test, ECG, or angiogram — or your doctor says your condition is too severe to undergo a stress test.

• Your condition has not improved with medication.

#5. Digestive System

Digestive system disorders, like Crohn's disease and ulcerative colitis, can qualify for disability benefits when they're severe enough to keep you from working. The exact requirements depend on your condition, but the SSA often looks at whether you've had serious complications like bowel obstructions, significant weight loss, or repeated hospital stays, and whether your symptoms continue despite treatment.

#6. Genitourinary Disorders

About 2.2% of disabled workers getting SSDI have a genitourinary disorder, according to the SSA's most recent data. Chronic kidney disease is the most common example. If you have kidney failure and need ongoing dialysis, you should actually qualify as a CAL/TERI claimant, and your application will be fast-tracked, as long as you also meet the program's non-medical rules.

When it comes to genitourinary disorders, you’ll likely qualify for benefits if some or most of the following are true:

• You’ve been diagnosed using a kidney or bone biopsy.

• You’ve received hemodialysis or peritoneal dialysis.

• You’ve experienced fluid buildup.

• You’ve experienced excessive weight loss due to kidney disease.

• You’ve been hospitalized at least three times in the last 12 months, at least 30 days apart.

• You’ve received a kidney transplant.

#7. Hematological Disorders

Hematological disorders affect the blood and the organs that make it. Examples include sickle cell disease, severe anemia, hemophilia, and bone marrow failure. These conditions are less common among SSDI recipients, about 0.3% according to the SSA's most recent data, but you can still qualify. Up-to-date lab results and records of complications, like hospital stays or blood transfusions, are key to proving your claim.

Your specific blood disorder may qualify if at least some of the following are true for you:

• You’ve been hospitalized at least three times within the last 12 months.

• You require RBC transfusions every six weeks.

• You have documented painful (vaso-occlusive) crises that require medication.

• Your complications (anemia, skin ulcers, pain, fatigue, etc.) limit your ability to complete tasks, function socially, or pursue the activities of daily living.

#8. Skin Disorders

Skin disorders are another less common category, making up about 0.3% of SSDI recipients according to the SSA's most recent data. Conditions like severe burns, psoriasis, and hidradenitis suppurativa can still qualify you, especially when flare-ups last a long time or keep coming back despite treatment. You might be eligible based on your skin condition if:

• You experience regular pain as a result of either your condition or your treatment.

• You have skin lesions in sensitive areas that prevent you from completing tasks (e.g., skin lesions on your hands that limit your fine motor skills, skin lesions on your feet that impact your ability to walk, or skin lesions on your joints that limit your use of an extremity).

• Your skin condition impacts your other senses (e.g., facial lesions that prevent you from comfortably talking or chewing) or your mental health.

• Your flare-ups are frequent enough to prevent you from keeping a consistent work schedule. 

#9. Endocrine Disorders

Diabetes is one of the most common endocrine disorders that can qualify for disability, but other conditions, like thyroid disorders and Addison's disease, can qualify too. The Blue Book doesn't have separate listings for endocrine disorders. Instead, the SSA looks at how your condition affects other parts of your body, like nerve damage, vision loss, or heart problems, and evaluates it under those listings.

You’re likely to qualify for benefits if some of the following are true for you:

• You’re insulin-dependent.

• You experience neuropathy or brain fog.

• You suffer from open wounds or require amputation.

• You experience numbness or tingling in your feet or hands, or have lost sensation in a limb.

• You have vision problems (e.g., diabetic retinopathy).

• You have severe gastrointestinal problems, such as constipation and incontinence.

#10. Congenital Disorders That Affect Multiple Body Systems

Congenital disorders are conditions present at birth, and some affect several body systems at once. In this section of the Blue Book, the SSA has one listing: non-mosaic Down syndrome. If lab tests confirm this diagnosis, such as a chromosome (karyotype) analysis signed by a doctor, you'll generally meet the listing without needing to show how the condition limits you. Other congenital disorders, including mosaic Down syndrome, are evaluated based on the body systems they affect. If you're applying for a child, learn more about SSI for children.

#11. Neurological Disorders

Neurological disorders cover a wide range of conditions, from stroke and epilepsy to neuropathy. Many of them can qualify you for disability benefits when they affect your ability to work, and the exact requirements depend on the condition. A few, like ALS, meet the Blue Book listing once they're diagnosed.

#12. Mental Disorders

Mental health conditions, which the SSA calls mental disorders, can qualify for disability benefits when they keep you from working. They're one of the most common reasons people get benefits. According to the SSA's most recent data, about 28% of disabled workers getting SSDI have a mental disorder, including conditions like depression, anxiety, and PTSD. To meet the listings for mental disorders, you need a combination of symptoms and limitations.

Still, qualifying with a mental health condition alone can be harder. Symptoms vary from person to person and don't always show up on tests, so strong evidence matters. That includes treatment records, notes from your therapist or psychiatrist, and a medical source statement describing how your symptoms affect your focus, memory, or ability to show up to work.

Many people who qualify have both mental and physical conditions, like PTSD with chronic pain, or anxiety with inflammatory bowel disease. The SSA looks at how all of your conditions affect you together. A disability lawyer can help you gather the right evidence and present your full picture.

#13. Cancer (Malignant Neoplastic)

Cancer can qualify you for disability benefits. Some cancers, especially aggressive ones or those that have spread or can't be removed with surgery, are on the SSA's Compassionate Allowances list, which can speed up approval. Your cancer may qualify you for benefits if any of the following are true:

• You’ve had a biopsy or procedure to remove cancer.

• You receive ongoing treatment and have recent scans.

• You have an oncology team (a specialist and a radiologist).

• You experience long-lasting side effects from treatment, such as chemo symptoms that last more than 12 months.

If you are in partial remission but still struggling to work due to your symptoms, you should still apply for disability benefits. 

#14. Immune System Disorders

Immune system disorders such as lupus, HIV/AIDS, and gout often make you eligible for SSDI. Symptoms and qualifications vary based on your exact condition, but you might qualify if:

• You have diagnostic testing to confirm your diagnosis (X-Rays, MRIs, CT scans).

• You experience fatigue, fevers, or involuntary weight loss.

• You have more than one organ affected by your condition.

• You have limited mobility or movement in your joints.

• You seek treatment from a neurologist, rheumatologist, or infectious disease doctor.

What if your condition is not in the Blue Book?

If your condition isn't in the Blue Book, you may still qualify for disability benefits. You'll need medical evidence showing that your condition keeps you from working, and you'll need to meet the program's other rules. For SSDI, that means having enough work credits, earning less than $1,690 a month from work in 2026, and being under full retirement age (67 for most people). If you don't have enough work credits, you may still qualify for SSI based on financial need.
