How these numbers are made
- Members are visible members: CMS suppresses any plan-county cell of ten or fewer, so small counties undercount. Market share excludes employer group plans.
- Enrollment is Oct 2026; the twelve months run Nov 2025 to Oct 2026; the election step compares December 2025 with January 2026.
- UnitedHealth is the parent organization UnitedHealth Group, Inc.; its 90 plans in Texas may sell under other brand names. The rating is the 2027 overall Star Rating of its contracts weighted by members in Texas; $0 premium and the in-network maximum are the 2027 filings weighted by members today.
- Plan fates are the ones assigned for contract year 2027.
- Every figure comes from public CMS data as Livmor reads it, and the page is rebuilt when a new month posts. Livmor Carrier Command, public CMS data.
