COPD Spirometry FEV1 Criteria: Listing 3.02

Listing 3.02A is the spirometry route to disability for chronic obstructive pulmonary disease (COPD), and it comes down to a number on a table. Your forced expiratory volume in one second (FEV1) must be less than or equal to the cutoff SSA publishes for your age, sex, and height without shoes. The test itself must pass quality rules in section 3.00E of the respiratory listings, which is where many claims are won or lost. The listing sits in 20 CFR Part 404, Subpart P, Appendix 1.

What FEV1 Measures

Section 3.00E1 explains the test. Spirometry involves at least three forced expiratory maneuvers in one session, each a maximum inhalation followed by a forced maximum exhale. FEV1 is the volume of air you exhale in the first second of that maneuver; FVC is the total volume over the whole maneuver.

SSA uses your highest FEV1 from the session to evaluate you under 3.02A, even if that value came from a different maneuver than your best FVC. Values are reported in liters at body temperature and pressure saturated with water vapor (BTPS), the standard pulmonary lab format.

How Age, Sex, and Height Set Your Cutoff

Criterion A keys the qualifying value to your age, sex, and height without shoes, not to a percentage of your predicted normal value. Taller people have larger lungs and therefore higher cutoffs, and the values differ between men and women. Ages 18 through 19 use Table I-A, which sets higher cutoffs; for example, a man under 60.25 inches tall meets 3.02A at 1.45 liters or less on Table I-A.

For age 20 and older, Table I-B of the current Blue Book sets these cutoffs, in liters (BTPS):

Your height is measured without shoes, and SSA assumes the recorded height on the test date was shoeless unless the evidence says otherwise. If your spine is abnormally curved, as in kyphoscoliosis, section 3.00E3a substitutes the distance between your outstretched fingertips, arms out to the sides, whenever that span exceeds your standing height.

The Post-Bronchodilator Rule

Section 3.00E2b adds a step for obstructive disease. If your FEV1 during testing is less than 70 percent of your predicted normal value, SSA requires repeat spirometry after you inhale a bronchodilator, unless a bronchodilator is medically contraindicated for you. The same repeat is required even if you used a bronchodilator before the test and your FEV1 still fell below 70 percent of predicted.

If no post-bronchodilator study exists, the test report must explain why. Results from testing done without bronchodilators remain usable when taking one would be unsafe for you, and the supervising physician may reschedule instead.

When SSA Will Not Use the Results

Section 3.00E2a requires you to be medically stable on the day of testing, with four examples that disqualify a study: being within 2 weeks of a change in prescribed respiratory medication; experiencing or being within 30 days of finishing treatment for a lower respiratory tract infection; experiencing or being within 30 days of finishing treatment for an acute exacerbation of a chronic respiratory disorder; and being hospitalized, or within 30 days of discharge, for a heart attack. Wheezing alone does not make you medically unstable.

The maneuvers themselves must be satisfactory, meaning maximum effort after a full inhalation, a sharp takeoff and rapid rise to peak flow, a smooth contour, and a duration of at least 6 seconds or a plateau of at least 1 second. The report must show the date, your name, age or date of birth, sex, and height without shoes, include legible volume-time tracings, and note anything that affected your effort.

Other Ways Through Listing 3.02

Spirometry is only the first of four doors. Criterion B uses FVC against Table II, which matters more in restrictive disease. Criterion C covers impaired gas exchange three ways: an average of two unadjusted single-breath diffusing capacity (DLCO) measurements at or below the Table III value for your sex and height (for example, 12.5 or below for men and 11.5 or below for women at 72.75 inches or taller); concurrent resting or exercise arterial blood gas values at or below the altitude-specific Table IV figures (a PaO2 of 55 mm Hg or less with a PaCO2 of 40 or higher at sites below 3,000 feet); or pulse oximetry at or below 87 percent at test sites below 3,000 feet, measured at rest or during or after a six minute walk test.

Criterion D takes a different shape entirely: exacerbations or complications requiring three hospitalizations within a 12-month period and at least 30 days apart, each lasting at least 48 hours, counting emergency department hours immediately before admission. SSA also considers the combined effects of obesity with COPD under section 3.00O.

If the Numbers Fall Short

A FEV1 above your table value does not end the claim. Under section 3.00R, SSA looks at listings in other body systems and at medical equivalence under 20 CFR 404.1526, where COPD combined with heart disease, obesity, or other impairments can equal a listing in severity.

Otherwise SSA assesses residual functional capacity under 20 CFR 404.1545, rating how long you can sit, stand, walk, and lift, and then applies steps four and five of the sequential evaluation in 20 CFR 404.1520, where the medical-vocational guidelines in 20 CFR Part 404, Subpart P, Appendix 2 weigh your age, education, and past work. Application procedures and appeals are outside the scope of this article.

Frequently Asked Questions

What FEV1 meets Listing 3.02A for COPD? Your FEV1 must be less than or equal to the Table I value for your age, sex, and height without shoes. For example, under Table I-B, which covers age 20 and older, a man 66.50 to under 68.50 inches tall meets 3.02A at 1.60 liters or less, and a woman of the same height meets it at 1.45 liters or less.

Is post-bronchodilator spirometry always required? If your FEV1 during testing is less than 70 percent of your predicted normal value, section 3.00E requires a repeat test after you inhale a bronchodilator, unless it is medically contraindicated. If no post-bronchodilator study exists, the report must explain why.

Can SSA refuse to use my spirometry results? Yes. Section 3.00E requires you to be medically stable at testing, and lists examples that disqualify results, including testing within 2 weeks of a medication change or within 30 days of an exacerbation or lower respiratory infection.
