According to code 6602 I would think so. My FEV-1 is 52% on average and I have been rated 60% for it. Best of luck.
6602 Asthma, bronchial:
FEV-1 less than 40-percent predicted, or; FEV-1/FVC less than
40 percent, or; more than one attack per week with episodes of
respiratory failure, or; requires daily use of systemic (oral or
parenteral) high dose corticosteroids or immuno-suppressive
medications 100
FEV-1 of 40- to 55-percent predicted, or; FEV-1/FVC of 40 to 55
percent, or; at least monthly visits to a physician for required
care of exacerbations, or; intermittent (at least three per year)
courses of systemic (oral or parenteral) corticosteroids 60
FEV-1 of 56- to 70-percent predicted, or; FEV-1/FVC of 56 to 70
percent, or; daily inhalational or oral bronchodilator therapy,
or; inhalational anti-inflammatory medication 30
FEV-1 of 71- to 80-percent predicted, or; FEV-1/FVC of 71 to 80
percent, or; intermittent inhalational or oral bronchodilator therapy 10
Note: In the absence of clinical findings of asthma at time of examination, a verified history of asthmatic attacks must be of record.
6603 Emphysema, pulmonary:
FEV-1 less than 40 percent of predicted value, or; the ratio of Forced
Expiratory Volume in one second to Forced Vital Capacity
(FEV-1/FVC) less than 40 percent, or; Diffusion Capacity of the
Lung for Carbon Monoxide by the Single Breath Method (DLCO
(SB)) less than 40-percent predicted, or; maximum exercise capacity
less than 15 ml/kg/min oxygen consumption (with cardiac or respiratory
limitation), or; cor pulmonale (right heart failure), or; right
ventricular hypertrophy, or; pulmonary hypertension (shown by
Echo or cardiac catheterization), or; episode(s) of acute respiratory
failure, or; requires outpatient oxygen therapy. 100
FEV-1 of 40- to 55-percent predicted, or; FEV-1/FVC of 40 to 55
percent, or; DLCO (SB) of 40- to 55-percent predicted, or;
maximum oxygen consumption of 15 to 20 ml/kg/min (with
cardiorespiratory limit) 60
FEV-1 of 56- to 70-percent predicted, or; FEV-1/FVC of 56 to 70
percent, or; DLCO (SB) 56- to 65-percent predicted 30
FEV-1 of 71- to 80-percent predicted, or; FEV-1/FVC of 71 to 80
percent, or; DLCO (SB) 66- to 80-percent predicted 10
