Cost per individual per group depends greatly on what the employer is able to negotiate. Our family policy is from a group with significantly older than norm population also considered high use. It is also small enough that catastrophic coverage of several individuals (transplants, cancer-especially treated at out of state facilities, etc) affects the cost more so than a much larger employee base. It has actually decreased in cost (7/8 years ago it was over $900/mo) since they changed carriers but the coverage is less (higher copays, deductables).
It will also change depending on the location and medical costs in that location. Policies that cover out of network at a reasonable copay are much more costly than those that provide only emergency out of network. If you travel, be sure to select good out of network coverage.
Some employers bundle short term disability with health care and that will make coverage more difficult to compare.
You have to have it, so you pay whatever it costs.
