What you have to prove
Mean pulmonary artery pressure equal to or greater than 40 mm Hg as determined by cardiac catheterization while medically stable.
Medical evidence SSA expects
Right heart catheterization results, echocardiogram, 6-minute walk test, RVSP measurements, and pulmonologist notes.
Common misconceptions
Echocardiogram estimates of pulmonary pressure aren't sufficient — SSA typically wants right heart catheterization, which is the gold standard.
Didn't meet the listing? You can still qualify via a Medical-Vocational
Allowance — SSA's determination that your residual functional capacity, combined with
your age, education, and work history, leaves no jobs you can do. See our
appeals guide for what to do after an initial denial.
