CMS files as loaded on 17 September 2026. Premiums, deductibles, maximum out-of-pocket amounts, star ratings and sanctions are reproduced from the Centers for Medicare & Medicaid Services landscape file as published in the September 2026 release. Enrolment counts are from the CMS monthly enrolment file; CMS suppresses any count of ten or fewer, which is why many plans show “fewer than 11” rather than a number. The only figures we calculate are the averages and medians marked as ours, from those same files. This is not a complete list of your options and it is not advice: see Medicare.gov or call 1-800-MEDICARE.
