Social Security Ruling 16-4p will appear in the Federal Register tomorrow. It concerns the use of genetic tests in determining disability. The bottom line on the Ruling seems to be that, yes, Social Security will consider genetic testing results but that, no, they won't pay for it. Their reason for not paying for it is that they say genetic testing isn't necessary to establish a finding of disability even though the Ruling itself admits that at least in the case of non-mosaic Down syndrome or Edward's syndrome or cystic fibrosis or chronic myelogenous leukemia such testing may be necessary. Maybe they ought to be more honest and say they don't want to spend the money and they really don't care if a few claims are unjustly denied.
