Some questions:
1. Did you pay the full premium for KP, or was some of it employer funded?
2. How many people are you paying for?
I once had KP through an employer. Best provider ever. However, at some point I was pondering quitting my job and looked up how much I'd have to pay in premiums to get the same copay, coverage, etc. It came out to over $900/mo for me + my spouse. That's almost $11K per year. Imagine how much more it would be if I had 2 kids.
I thought I'd just check now to see what the cheaper plans look like. The cheapest plan is $527/mo. Deductible is $6550/person (over $13K for household). So I'd pay over $6K if I didn't seek any treatment. And I could pay as much as $19K out of pocket (premium + deductible) before insurance kicks in.
KP is an awesome provider when I'm not paying for it :-)
BTW, I do have KP currently, under a different employer. Current wait time to see my PCP is 3 weeks (I've seen as high as 4 weeks). It used to be 1-3 days - I always wonder if changing employer plays a role (same PCP).
