@galileogirl – most important thing there though is, yes, you are right, if you go don’t lock into an individual plan now, and end up losing domestic partner benefits and exhaust COBRA, if ALL that happens, AND in the interim you develop a “pre-existing condition”, you could have a VERY hard time getting on an individual plan. However, two things to consider.
1) As I said, MOST employer based plans (not all, but if your SO checks with her benefits administrator you will be able to find out), have a conversion option once COBRA runs out. I have a pre-existing condition, and that’s the reason I have good health coverage is that I was able to get a conversion plan. If that’s the case, the reason they have a conversion option is so that if you can’t get private insurance, you have a plan you CAN get on. Sure, I have a $1,000 deductible, but it’s less than $300/mo, I get drug coverage, and I pay a reduced rate on all my medical billings up to that first $1,000. Again, I wouldn’t automatically say “get your own plan” because the reality might be that this is a worse option, because…
2) An individual plan, hey, they can change the rules, they can jack up the rates, there is no group behind it to keep them honest, there is no incentive not to start reducing your level of benefits or start adding uninsured conditions. What you’re fearing could happen if you went with the employer plan could just as easily happen with an individual plan. Even with individual plans, you have annual renewals. If your company gets an annual renewal, they may jack rates by as much as 20%, and your company might shop around for another group plan and maybe switch providers. But you as an individual, you get to annual renewal and they could a) jack the rates up so you could no longer afford it, b) add a list of conditions which as of renewal time are no longer covered or are covered at a significantly reduced rate, or c) increase annual out of pocket deductibles to the point where you might as well have no insurance at all (not to mention d) all of the above). The benefit to being on an employer plan as long as possible is, if they try to pull all this on a company, the company has leverage to negotiate or go somewhere else. But you, especially if you now have a pre existing condition, have nowhere else to turn and are essentially at their mercy.
