There’s not a whole lot to it, it starts with finding a good doctor and practice which isn’t unique to concierge. Beyond that you pay an annual fee per person, around me that’s in the $2-3k range. That fee is out of pocket and outside insurance: this fee doesn’t cover specialists, surgery, etc. In exchange for the fee you typically get more attention and appointments on demand. The downside is that the cost is on top of insurance and you could argue its buying into or supporting a two tiered healthcare system, where the benefits you’re getting are because you’re pricing out people who can’t afford to do the same.
