Rating

Note 1: Evaluate cor pulmonale, which is a form of secondary heart disease, as part of the pulmonary condition that causes it.

Note 2: One MET (metabolic equivalent) is the energy cost of standing quietly at rest and represents an oxygen uptake of 3.5 milliliters per kilogram of body weight per minute. When the level of METs at which dyspnea, fatigue, angina, dizziness, or syncope develops is required for evaluation, and a laboratory determination of METs by exercise testing cannot be done for medical reasons, an estimation by a medical examiner of the level of activity (expressed in METs and supported by specific examples, such as slow stair climbing or shoveling snow) that results in dyspnea, fatigue, angina, dizziness, or syncope may be used.

7000 Valvular heart disease (including rheumatic heart disease):

During active infection with valvular heart damage and for three months following cessation of therapy for the active infection 100

Thereafter, with valvular heart disease (documented by findings on physical examination and either echocardiogram, Doppler echocardiogram, or cardiac catheterization) resulting in:

Chronic congestive heart failure, or; workload of 3 METs or less results in dyspnea, fatigue, angina, dizziness, or syncope, or; left ventricular dysfunction with an ejection fraction of less than 30 percent 100

More than one episode of acute congestive heart failure in the past year, or; workload of greater than 3 METs but not greater than 5 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; left ventricular dysfunction with an ejection fraction of 30 to 50 percent 60

Workload of greater than 5 METs but not greater than 7 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; evidence of cardiac hypertrophy or dilatation on electro-cardiogram, echocardiogram, or X-ray 30

Workload of greater than 7 METs but not greater than 10 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; continuous medication required 10

7001 Endocarditis:

For three months following cessation of therapy for active infection with cardiac involvement 100

Thereafter, with endocarditis (documented by findings on physical examination and either echocardiogram, Doppler echocardiogram, or cardiac catheterization) resulting in:

Chronic congestive heart failure, or; workload of 3 METs or less results in dyspnea, fatigue, angina, dizziness, or syncope, or; left ventricular dysfunction with an ejection fraction of less than 30 percent 100

More than one episode of acute congestive heart failure in the past year, or; workload of greater than 3 METs but not greater than 5 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; left ventricular dysfunction with an ejection fraction of 30 to 50 percent 60

Workload of greater than 5 METs but not greater than 7 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; evidence of cardiac hypertrophy or dilatation on electrocardiogram, echocardiogram, or X-ray 30

Workload of greater than 7 METs but not greater than 10 METs results in dyspnea, fatigue, angina, dizziness, or syncope, or; continuous medication required 10

7002 Pericarditis:

For three months following cessation of therapy for active infection with cardiac involvement 100

Thereafter, with documented pericarditis resulting in:

Chronic congestive heart failure, or; workload of 3 METs or less results in dyspnea, fatigue, angina, dizziness, or syncope, or; left ventricular dysfunction with an ejection fraction of less than 30 percent 100

More than one episode of acute congestive heart failure in the past year, or; workload of greater than 3 METs but not
