I've been schooled recently and I hear on good word that the way the SSA respiratory regulations are about as good as they're ever going to get, with respect to SSDI requirements. It's said that summertime would bring an announcement for proposed changes, if any. But the general consensus is that it is hoped that things stay as they are. So for those who are considering application, you better get on it and fast. Talk to the CF legal team. Don't go it alone or hire some DUI lawyer who spends an hour on your case. You're wasting your time, otherwise.

And as fanciful as the prospect, a disability declaration would literally be an act of God to achieve. The government has all but closed the door on the "compassionate allowance" prospect for just about all diseases unless there is very specific treatment and basically an immediate clear and present time constraint for life. SSA did it for two other diseases, (ALS and kidney) and that was it. They were done because it opened the door for others. By default, the requirement focus is extremely narrow so given that CF patients have a variety of expression and treatments, it would be extremely difficult to achieve a disability declaration as a default for all patients. It's already been tried years ago...and as difficult and well intended as the fight was, it ultimately failed. So enough of that.
The bigger issue is the expense of medications. No offense to any pharmaceutical but it's hard for me to understand why any of the medication we take is so darned expensive and as a result, life-limiting. Yes, it's unique and CF-specific but $300,000/year? I dunno. No wonder the government chokes at the prospect of paying under Medicare/Medicaid. So just imagine how they feel about disability. So who do we blame, if there is blame? The government who is cost-conscious and don't want to pay or pharmaceuticals who don't want to lower costs? Hmmm...
There you have it.
