Corrections
If a premium, a copay, a status or a count on PlainMedicare looks wrong, write to hello@plainmedicare.com with the page address and the figure. Confirmed errors are fixed at their source and listed here.
Which errors have been fixed?
- A table of insurers with five-star plans showed an enrollment column that read zero for every insurer, because the file it drew on held no enrollment for them; the column was removed.
No error has been reported against the 2027 pages published on October 7, 2026. Reported ones will be listed here with the date they were fixed.
What counts as an error here?
A figure that differs from the CMS file it names, a plan shown in the wrong county, a status the crosswalk does not support, or a sentence that says more than the file does. A plan's network, a drug price at your pharmacy, or a benefit your plan's letter describes differently are outside the files; ask the plan, and if the CMS file itself is wrong, CMS publishes revisions that the site loads when they appear.
What is checked before a rebuild goes live?
Each rebuild stops, rather than publish, if a county in a CMS file matches no county, if a 2026 plan has no crosswalk row, if one CMS spending row would appear on two drug pages, if a page shows an empty value, or if a plan that folds into another would be shown as ending. The full list is on the methodology page.
How do you report one?
Include the page address, the figure, the value you expected and where you saw it: Medicare Plan Finder, the plan's Annual Notice of Change, or a CMS file. If the page matches the latest CMS file, we reply with the file and its date; if CMS revises the file, the page follows when the site is rebuilt.
