We have a LOT of experience in health/medical insurance admin systems across Australia, New Zealand, Asia, South Africa.
About 2 years ago we built a health insurance admin system using Aware. It was a prototype for demo purposes. It was for a tender for a Chinese insurance company who had literally millions of policy holders. It was multi-lingual too. We never got the contract so we never had to scale it, or make it production ready, but I did look into it and concluded that with the right structure/design we could scale it.
It was pretty much a full fledged admin system... Pm me if you're interested and I can share with you some learnings.
