About these numbers
Premiums are the CMS-listed rate for a single non-smoking adult, before any premium tax credit. Most marketplace buyers qualify for a credit based on household income — the actual price can be far lower than the list rate, especially for silver plans. Deductibles and out-of-pocket maximums are for in-network care and vary by plan design. Check doctor and hospital networks before enrolling: a cheaper plan that excludes your doctors is not cheaper.
