How will you protect your business when they decide to cut out the middle-man(you) and begin working with their networks directly to renogotiate procedure costs and kick-back discounts to employers for using these selective Cost+Quality networks? Truth is they're already doing this.
EDIT: My points may be moot - Are you only working with self-insured companies? That's the only thing that makes sense here given that you're splitting costs with the employer.
The premise of centres of excellence is that paying fair rates for top quality providers gives better outcomes over the long term and reduces overall costs to the company - not specifically the procedure costs.
Medical care free at point of use is one of the best things to aspire to in the world imo, I'm just trying to make sense of your model.
I.e., absent this service, would employees find it considerably more difficult to get treatment? (The article doesn't exactly say this, but hints in that direction.)
If so, I'd be concerned that it induces employees to consume more medicine. So while one might save money on cost per procedure, the # of procedures would go up.
(Due to RAND/Oregon, we also know it's unlikely that marginal increases in medical consumption would improve health, so regardless of how much I might care about my employees, this would be a bad thing.)
This is one case of "I'll believe it when I see it."
EDIT: I didn't notice this at first, but the first paragraph of the TechCrunch article says "workers of the world," so this wild dream isn't limited to the US, it seems.
If you want to see little government involvement, look at India (that's where I go when I need work done).
I'm not sure how your question relates to my comment.
My current insurance only has a small list of specialists in my area, and only one who was actually accepting patients and didn't have a 3 month wait list.
