Corrections

If a star rating, premium, enrollment count, supplemental benefit, or Part D figure on PlainMedicare looks wrong, report it with enough detail to reproduce the page and compare it with the CMS Medicare Advantage and Part D public files for that plan year. The same process is documented in our editorial and corrections policy.

How to report

  1. Report. Email corrections@plainmedicare.com or use the contact page with the page URL, the figure that looks off, and what you think it should be.
  2. Source. Include a link to the CMS Plan Finder record, a CMS Star Ratings public-use file, or another primary source you think we should match.
  3. Scope. Say whether the issue is a raw CMS field, a derived ranking or aggregate, or a stale plan-year badge.

What happens next

We verify reports against the published CMS source for that plan, county, and plan year, and correct confirmed issues in the canonical database or pipeline so affected pages update together. Material fixes are noted on the public data changelog. PlainMedicare is an informational research reference, not medical, insurance, or enrollment advice.

When the figure is correct on our side but the upstream CMS release is the latest published file, we will say so and point you to the official record. We mirror the public CMS release and cannot rewrite a plan's filing on an insurer's behalf.

For how figures are derived, see the methodology page. For publisher accountability, see About PlainMedicare.
