Hi, welcome and congratulations for making the decision to donate.
I live in the San Francisco Bay Area and donated in Chicago. I too did my testing at home, but the transplant center required me to have the CT scan in their facility. They also wanted me to meet the surgeon. So I flew out for three days, had the CT and a consultation with the surgeon. Before that I spoke to the coordinator many times on the phone, and had the social worker evaluation over the phone also. I definitely asked all the questions of the surgeon when I met him. The surgery was scheduled for six weeks later. However, my recipient became too ill and it was postponed several months. By that time, my surgeon had left the program and there was a new one. I met him two days prior to the procedure and asked him even more questions. I was fortunate. Both surgeons were very passionate and eager to explain everything.
For the actual procedure, my husband and stayed in a local hotel for the week of the surgery but I recovered for an additional 10 days at the home of a relative. The hotel was near the transplant center and had special rates for hospital patients and their families. I had to do some calling around and also had to ask people to honestly tell me about the neighborhoods where the hotels were located before I chose one. Oh yes, the airline also credited me enough miles to bump me up to first class flying home, since I had to be able to stretch my legs and get up. I registered for the Frequent Flyer program and called them directly about it, and they made the arrangements. It was American Airlines.
The airfare for you and a companion, and any travel expenses related to the transplant, are all tax-deductible as medical expenses. If you have access to a Flexible Spending Account through an employer plan, the expenses are eligible for pre-tax withholding. But if you're doing it this year, it's too late to arrange for that, so keep track for 2011 income taxes.
Your medical expenses should all be paid by your recipient's insurance. You should not have any medical expenses due to the transplant.
I hope this helps. I did not have small children so I cannot give you any insight there. But there are many on here who will chime in with their experiences in that respect.
Best wishes!
