I am strictly Medicare part A and B, D as far as coverage goes with a medigap insurance... From what I understand, what is covered under part B is are albuterol, duonebs, pulmozyme, TOBI, and NAC (Mucomyst) and a few others, but not Cayston (as far as I know). Part B pays for 80% of the costs, the rest is your financial obligation. This is where my medigap insurance kicks in, my policy picks up the remaining 20%, so I pay nothing, no co pays. I would be flat broke if I were on TOBI and had to pay 20% out of my pocket! Yes, it costs extra money per month for a medigap policy, but it has saved me thousands when it comes to admissions, part B meds, doctor's visits etc. You just need to figure out what will work best for you, sometimes you need to be a little creative to get around some of Medicare's pitfalls (such as home IV's, they don't cover supplies, but if you have part D insurance, you could get some meds ordered ahead of time to keep on hand for when it is needed, which is exactly what I do with my doc's blessing)
If you have any more questions, shout it out and we'll see what we can come up with!
