Demand Studios has posted their new health insurance plan on their site, and sent a mass email out to (I suppose) anyone who is or has signed up as a provider. If you didn't get that mass email, the info is available to the general public without a sign in at Demand Studios Health Insurance.
I'm not a health insurance expert, but coverage and payouts look similar to other freelance offerings such as those available through memberships with the Editorial Freelancers Association or MediaBistro's freelance health insurance plans.
Demand Studios' costs range from approximately $50 to $400 per month. To be eligible, writers must write 30 articles per month, and copyeditors must review 200 articles per month.
Don't miss my multiple articles with more information on how to manage health insurance as a freelance writer.
