What you have to prove
Meet via: (1) cyanosis at rest with specific hematocrit, oxygen saturation, or pulmonary vascular resistance values; OR (2) intermittent right-to-left shunting with documentation of specific oxygen saturation levels; OR (3) secondary pulmonary vascular obstructive disease with specified pulmonary pressures.
Medical evidence SSA expects
Echocardiogram, cardiac catheterization, pulmonary function testing, ABG analysis, and pediatric and adult cardiology records.
Common misconceptions
Many adults with surgically corrected congenital heart disease don't qualify because correction resolves the hemodynamic findings SSA requires.
