A dated record of real changes to PlainHealthPlan's dataset and site: data refreshes, corrections, and trust improvements. See the editorial & corrections policy for how reports are verified. We never backfill or invent an entry; an empty gap between dates means nothing material changed.

PlainHealthPlan launched on March 18, 2026. See the methodology page for how the dataset is built, and corrections to report an issue.

1. 2026-08-10 Correction

   Finished folding CMS Expanded Bronze into Bronze-tier prose and aggregates so bronze coverage is not understated while plan-level rows keep the source label.

2. 2026-08-07 Correction

   Fixed year-over-year premium change that divided mismatched metal populations, and folded Expanded Bronze into Bronze-tier county/trend averages.

3. 2026-07-09 Correction

   Corrected ACA enhanced-subsidy expiration wording and two stale figures that no longer matched the current CMS release.

4. 2026-07-08 Correction

   Stopped fabricating guide Published dates in production so editorial timestamps only appear when a real review date exists.

5. 2026-07-05 Correction

   Fixed the ACA subsidy calculator that still used 2024 Federal Poverty Level figures while labeling them as 2026.

6. 2026-03-18 Launch

   PlainHealthPlan launched with ACA marketplace premium and plan data for HealthCare.gov counties from CMS Public Use Files.
