Your individual pre-existing condition does not bubble up to the group. However, when negotiating as an individual, then each pre-existing condition does get considered and factored into the cost. There's power in groups.
Well, in most situation yes. You as an individual. There other problem with pre-condition, it's very broad. They can make up all kinds of BS and claim your application must be filed different because of some "magical" precondition.
So at the same time, if one has no health conditions, one could expect to get a cheaper rate on an individual plan?
