Important notice

NPI Profile is not an insurance company, agent or broker. We do not sell insurance, enroll anyone in a plan, or give tax, legal, financial or insurance advice. This free tool organizes public files from CMS and insurers so you can compare Marketplace plans and check whether your current or future doctor is in a plan’s network. It is not affiliated with CMS, HealthCare.gov, any state exchange or any insurer.

Premiums, costs, coverage, provider networks and plan availability can change and may differ from what is shown here. Premiums are full prices before subsidies (premium tax credits), and your actual cost depends on your household and income. Before you enroll, confirm the details with the insurer and the doctor’s office, and enroll through Get Covered Illinois. For help choosing a plan, HealthCare.gov lists free local assisters and licensed agents.
