Congestive Heart Failure: Meeting Listing 4.02

Congestive heart failure (CHF) is evaluated for Social Security Disability Insurance (SSDI) under Blue Book Listing 4.02, and the listing always demands two showings at once. Paragraph A requires objective imaging evidence of ventricular dysfunction, either systolic or diastolic, and paragraph B requires a separate measure of functional severity. The listing appears in 20 CFR Part 404, Subpart P, Appendix 1, and applies only while the claimant is on a regimen of prescribed treatment.

The Social Security Administration (SSA) treats heart failure as a single category whether it flows from coronary artery disease, cardiomyopathy, hypertension, or valve disease, as explained in section 4.00D1. What separates approved from denied claims is usually the fit between the echo numbers in paragraph A and the treatment history in paragraph B.

Two Kinds of Failure, Two Sets of Measurements

Section 4.00D1a divides chronic heart failure into two types. Systolic dysfunction is the inability of the heart to contract normally and expel enough blood. It produces a dilated, poorly contracting left ventricle and a reduced ejection fraction, the percentage of blood in the ventricle pumped out with each contraction.

Diastolic dysfunction is the inability of the heart to relax and fill normally. It produces a thickened, stiff ventricular muscle, increased filling pressure, and a normal or even increased ejection fraction. Because the pumping percentage looks fine, the listing relies on structural measurements instead.

Paragraph A1: The Systolic Criteria

Listing 4.02A1 is satisfied by systolic failure with either of two findings on appropriate medically acceptable imaging:

• A left ventricular end diastolic dimension (LVEDD) greater than 6.0 centimeters, or
• An ejection fraction of 30 percent or less.

Both measurements must be taken during a period of stability, not during an episode of acute heart failure. Section 4.00D2a makes the same point: an ejection fraction recorded in the middle of a crisis, or a transiently improved reading after hospital treatment, does not establish the chronic level of severity the listing describes.

Acceptable imaging under 4.00D2a includes chest x-ray, echocardiography (M-mode, 2-dimensional, and Doppler), radionuclide studies, and cardiac catheterization. Echocardiogram reports are the workhorse evidence because they capture chamber size, wall thickness, and ejection fraction in one document. SSA will not purchase catheterization studies, as section 4.00B6 explains, but it will consider catheterization results that already exist in the record.

Paragraph A2: The Diastolic Criteria

Listing 4.02A2 covers diastolic failure with a different set of numbers:

• A left ventricular posterior wall plus septal thickness totaling 2.5 centimeters or greater on imaging, and
• A left atrium enlarged to 4.5 centimeters or greater, with
• A normal or elevated ejection fraction, again during a stable period.

Section 4.00D2a(iii) notes that this thick-wall and enlarged-atrium combination is the pattern clinically associated with diastolic failure. The chronic thickened heart cannot fill, pressure backs up into the left atrium, and the atrium stretches. Claimants with this pattern often carry a diagnosis of heart failure with preserved ejection fraction, and paragraph A2 is where their claims live.

Whichever type applies, section 4.00D2b requires that the medical history and physical examination describe characteristic symptoms and signs of congestion or limited cardiac output, not just numbers. Symptoms SSA names include fatigue, weakness, shortness of breath at rest or with activity, cough, chest discomfort, breathlessness lying flat (orthopnea), and episodes that wake a person from sleep (paroxysmal nocturnal dyspnea). Signs include an enlarged liver, ascites, elevated jugular venous pressure, rales, peripheral edema, and rapid weight gain from fluid.

Paragraph B1: Persistent Symptoms When Exercise Testing Is Too Risky

The first functional route is persistent symptoms of heart failure that very seriously limit the ability to independently initiate, sustain, or complete activities of daily living, in a person for whom a medical consultant (MC) has concluded that an exercise tolerance test would present a significant risk. This path fits claimants too sick to be safely exercised, and the record should show treating sources describing how bathing, dressing, and walking across a room are limited by fatigue and breathlessness.

Paragraph B2: Recurrent Acute Episodes With Fluid Retention

The second route targets the revolving-door pattern of decompensated failure. Listing 4.02B2 requires three or more separate episodes of acute congestive heart failure within a consecutive 12-month period, with evidence of fluid retention from clinical and imaging assessments at the time of the episodes, each requiring acute extended physician intervention such as hospitalization or emergency room treatment lasting 12 hours or more, and separated by periods of stabilization.

Section 4.00D4c defines those periods of stabilization. For at least 2 weeks between episodes, the record must show objective evidence of clearing of the pulmonary edema or pleural effusions and evidence that the claimant returned to, or was medically considered able to return to, the prior level of activity. Emergency department records, admission notes, chest imaging during each episode, and daily weights documenting fluid shifts are the evidence that satisfies this paragraph.

Paragraph B3: Failing an Exercise Tolerance Test at 5 METs

The third route is an inability to perform on a sign-or symptom-limited exercise tolerance test (ETT) at a workload equivalent to 5 METs (metabolic equivalents) or less due to any of the following:

• Dyspnea, fatigue, palpitations, or chest discomfort.
• Three or more consecutive premature ventricular contractions (ventricular tachycardia), or increasing ventricular ectopy with at least 6 premature ventricular contractions per minute.
• A decrease of 10 mm Hg or more in systolic blood pressure below the baseline or the preceding exercise reading, due to left ventricular dysfunction despite increasing workload.
• Signs attributable to inadequate cerebral perfusion, such as ataxic gait or mental confusion.

Section 4.00C3b explains that the ETT must continue until a sign or symptom indicates the claimant has exercised as much as is safely possible. An inability to sustain even 5 METs, roughly the demand of casual walking, marks an exertional ceiling far below any full-time job. Sections 4.00C6 through 4.00C8 govern when SSA will purchase an ETT, including the requirement that an MC assess risk first, and section 4.00C9 treats test results as timely for 12 months.

Treatment, Timing, and the Longitudinal Record

The listing applies while on a regimen of prescribed treatment, and section 4.00B1 calls for a longitudinal record covering not less than 3 months of observation and treatment in most cases. Section 4.00B4 adds that SSA will generally wait 3 months after a heart attack, bypass surgery, another open-heart procedure, or angioplasty before evaluating, unless the existing evidence already supports a decision, and it will wait out periods of instability before assessing severity.

Section 4.00D2b also notes that signs of fluid retention need not appear on every examination because prescribed treatment can suppress them. A controlled exam therefore does not sink a claim, but a pattern of severity across the record must still be established, consistent with the definition of persistent at 4.00A3b, meaning present for at least 12 months with few exceptions.

When Heart Failure Does Not Meet 4.02

If the criteria are not met, section 4.00I3 directs the next steps. SSA considers other body systems, then medical equivalence under 20 CFR 404.1526, then residual functional capacity (RFC) under 20 CFR 404.1545 with the claimant's age, education, and work experience. Related routes exist for arrhythmias under Listing 4.05, ischemic disease under Listing 4.04, and aneurysm under Listing 4.10. A heart transplant earns 1 year of disability under Listing 4.09, after which SSA evaluates the residual impairment.

At steps four and five of the sequential evaluation under 20 CFR 404.1520, exertional limits documented by an ETT failure or repeated hospitalizations, combined with the medical-vocational guidelines in 20 CFR Part 404, Subpart P, Appendix 2, often decide older claimants' cases at the sedentary or light level.

NonMedical Requirements in 2026

SSDI additionally requires insured status under 20 CFR 404.130, generally 20 work credits earned in the 10 years ending with onset. In 2026, one credit is granted for each $1,860 of covered earnings, up to four per year. Earnings must also stay below the substantial gainful activity level of 20 CFR 404.1574, which is $1,670 per month for non-blind claimants and $2,780 for statutorily blind claimants in 2026.

Frequently Asked Questions

What ejection fraction meets Listing 4.02 for systolic heart failure? Under Listing 4.02A1, systolic failure is documented by a left ventricular end diastolic dimension greater than 6.0 centimeters or an ejection fraction of 30 percent or less, measured during a period of stability and not during an episode of acute heart failure.

Can you meet Listing 4.02 with a normal ejection fraction? Yes. Listing 4.02A2 covers diastolic failure, where the stiffened ventricle does not fill properly and the ejection fraction is normal or elevated. It requires a left ventricular posterior wall plus septal thickness of 2.5 centimeters or greater together with a left atrium enlarged to 4.5 centimeters or greater.

Does fluid retention matter under Listing 4.02? Yes. Under 4.02B2, SSA looks for three or more separate episodes of acute congestive heart failure within a consecutive 12-month period, each with evidence of fluid retention from clinical and imaging assessments, each requiring hospitalization or emergency room treatment lasting 12 hours or more, and separated by periods of stabilization.
