Scott and White Marketplace plans ending: Dallas, Texas

Dallas: confirm your home county

CMS's 2026 individual-market Service Area file identifies 104 counties for Baylor Scott and White Health Plan (issuer 40788). These are the former plan's enrollment area, not a guarantee of replacement-plan availability or a provider-network list. This inventory uses both TXS001 and TXS002; the older map alone is not the source.

Census lists Dallas across Collin County, Dallas County, Denton County, Kaufman County, Rockwall County. The 2026 Marketplace service-area records include Collin County, Dallas County, Rockwall County for this locality. Other portions of this city are outside that recorded footprint; use your exact home address and current policy notice.

Use the linked county guide to find neighboring communities and county-specific Marketplace resources. If you visit a facility across county lines, check its network separately from your enrollment county.

Geography verified October 30, 2026 against CMS PY2026 Service Area data and Census place–county relationships. Census geography is dated 2020; newer incorporations may not be included. Carrier documents and Marketplace eligibility determine individual coverage.

Why a Dallas mailing address is not enough

The Census reference places Dallas in 5 counties. A residence in Collin County or Dallas County or Rockwall County intersects the recorded former Marketplace footprint; that does not establish the replacement plans offered at that address.

The Denton County and Kaufman County portions are not in this issuer's recorded 2026 service area. Do not assume every Dallas resident held one of the affected plans. Check the county on your Marketplace application and compare it with your policy notice.

Arrange January coverage in Dallas

Select a replacement plan by December 15, 2026 for a January 1, 2027 start. A selection from December 16 through January 15 generally starts February 1, 2027, which may leave a January gap. Coverage requires eligibility, enrollment acceptance and the first premium payment.

Review any automatic replacement shown in your HealthCare.gov account rather than assuming the new plan has the same doctors or benefits. Keep the selection confirmation and verify the effective date with the new insurer before changing existing coverage.

Dallas provider and plan checklist

1. Use your residential address to find available plans. A Dallas provider may treat people from several counties.
2. Check the exact 2027 plan name and network, the clinician's practice address and the facility—not just the carrier or health-system name.
3. Check prescriptions, pharmacy access, referrals and prior authorization in the replacement plan's documents.
4. Confirm acceptance and the coverage start date; ask the carrier about transition-of-care rules if needed.

The Marketplace plan exit does not mean Baylor Scott & White facilities are closing or that employer-group and Medicare Advantage plans are ending. The health system says it will continue accepting Marketplace insurance, but individual network participation requires verification.

Sources and next steps for Dallas
