Jeanette,
Yes, a deductible means you pay the full cost of healthcare until you have paid that amount. So January can be a very expensive month...we just save up knowing it is coming.
Most plans I believe do have an out of pocket max, but the range varies widely. My husbands employer offers a few medical plans to choose from. There is one that has an out of pocket max of $5,500 per individual or $16,500 per family! And remember the cost of your prescription medications are normally NOT included in this amount. So you would have to pay this amount, PLUS the cost of medications.
As far as the i-neb...I'm not familiar with this, but you normally only get an e-flow if you are on inhaled antibiotics. My daughter nebs: albuterol, hypertonic saline & pulmozyme - and we use a "mobileaire" compressor with a "pari lc plus" nebulizers. If you only neb saline then most likely you will get whatever "brand" your insurance has contracted with. If you start nebbing something like pulmozyme, there are certain compressor/nebulizer combos that are recommended for using that drug.
Julie will probably be the best person to answer your question about pre-existing conditions. But generally, pre-existing conditions are not a problem with an employers group plan. My husband changed jobs a few years ago and we had no problem with the getting coverage under the new plan. But we had no gap in coverage...so that may be something to look into.
Feel free to ask anything that comes to mind. I'll do what I can to help.
