I broke my leg in Europe in January 2014, see attached, and had Westpac CC insurance via Zurich. They paid for everything, but I had to do all the chasing. They would not start the claim until they had proof that I was covered. So I had to call Westpac and ask them to close off my statement early so I had a statement I could send Zurich - from my hospital bed while doped up!
They tried to get me to wait five more days after ready to go home and go home on my original Qanats flights, with a 10 hour stop -over in Dubai, so I found a Singapore Airlines flight out of Geneva the next day and pleaded with them to get me on it. In the end they did as end of school holidays and no other suitable (needed a long haul, lie down business seat as leg was in a frame) available flights. The only good part of the whole experience is that used some of my Krisflyer points to upgrade me and the two children from Business to Suites, which had a real bed and so made a nightmare trip home a little easier.
They also got me to do the run-around between them and the lift ticket ski insurance to work out who was going to pay for the refund of unused lift ticket, on-mountain rescue and helicopter to the hospital. With the different time zones and both insurance companies demanding I provide information as to if the other would or would not pay. In the end, I gave Zurich the phone number of the Ski Insurance company and they sorted it out.
Finally, I also had to cancel a later ski trip to Japan, due to the same accident, where the flights to Japan were on Qantas and Zurich wanted me to produce a value for a commercial flight of the same booking class on the same day (ha!) and Qantas would not give it to me as they reasonably argued many ticket buckets. So I spent ages going back and forth and then submitted a best guess estimate, to find out that the actual assessors just used the value on the Qantas top-up points system to value my points. What a PITA!

So, to sum up, the credit card insurance works well, but you have to be proactive and look out for yourself or you will get the cheapest, easiest option for them. You can call the Zurich credit card insurance line and you will hear how many CC companies use them: "Press one for ANZ, 2 for Westpac, etc etc" Same insurer, but it is a bit tricky as all policies are quite similar in most of what they provide but can be different in small ways. EG some cover recreational skiing, but only on piste, some don't cover skiing and some, like Westpac don't mention skiing at all as an exclusion, but when I called up they asked if I was skiing on piste as skiing off-piste was not covered. I think that the call centre operator was wrong, but luckily 1) I was skiing in bounds and 2) I don't think anyone ever checked.
Hope this helps, and that you like my holiday "snaps", below.
