Best Health Insurance in Washington, D.C.

Kaiser Permanente has the best health insurance in Washington, D.C., with Silver HMO plans averaging $607 per month for a 40-year-old. That's $69 less per month, or $828 less per year, than Blue Cross Blue Shield's Silver PPO at $676.

Kaiser is the better fit for shoppers comfortable receiving care within its network. Its HMO requires members to use in-network providers for non-emergency care.

Blue Cross Blue Shield costs more but provides PPO plans, which include access to out-of-network providers and specialist care without referrals. It's worth the higher premium if you regularly use providers outside Kaiser's network.

Washington, D.C.'s marketplace has only these two carriers, so your choice largely comes down to lower HMO premiums versus broader PPO provider access.
