The Dallas–Fort Worth Metroplex is one of the largest Medicare markets in Texas, and one of the most competitive. Across Dallas, Tarrant, Collin, and Denton counties, beneficiaries often have dozens of Medicare Advantage plans to choose from each year — plus the option of Original Medicare paired with a Medicare Supplement and a Part D drug plan.
But here's what surprises many people in DFW: the plans available to you, and the networks behind them, depend heavily on which county you live in. A plan that's a great fit in downtown Dallas can look very different from one in Plano, Fort Worth, or Frisco. Understanding that county-level variation is the key to choosing well.
Why plan choices vary across the Metroplex
Medicare Advantage plans are sold by private insurers and approved by Medicare county by county. Each plan builds a network of doctors, hospitals, and pharmacies — and those networks tend to follow the dominant health systems in each area. So as you move across the Metroplex, the "best" plan changes with the providers around you.
Three things drive the differences:
- Provider networks. DFW networks are often built around systems like UT Southwestern, Baylor Scott & White, Texas Health Resources, Methodist, and Medical City — but which ones a plan includes varies by plan and county.
- Plan availability. The number and type of plans offered can differ from one county to the next.
- Drug coverage and pharmacies. Part D formularies and preferred pharmacies change by plan, which affects what you actually pay for your medications.
A county-by-county look
Dallas County
The urban core of the Metroplex — Dallas, Irving, Garland, Richardson, and Mesquite — is among the most plan-rich Medicare markets in Texas. Networks here frequently center on UT Southwestern, Baylor Scott & White, Methodist Dallas, Parkland, and Texas Health. See Medicare in Dallas County.
Tarrant County
Anchored by Fort Worth and Arlington, Tarrant County has its own distinct set of plans and networks, often built around Texas Health Fort Worth, Baylor Scott & White All Saints, JPS Health Network, and Medical City. See Medicare in Tarrant County.
Collin County
Plano, McKinney, Frisco, and Allen sit in one of the fastest-growing areas in the country, with deep plan options and networks like Texas Health Plano, Baylor Scott & White McKinney, and Medical City. See Medicare in Collin County.
Denton County
Denton, Lewisville, and Flower Mound round out the northern Metroplex, with networks that often include Texas Health Denton, Presbyterian Flower Mound, and Medical City Denton and Lewisville. See Medicare in Denton County.
How to choose the right plan in DFW
Whichever county you're in, the process is the same:
- Start with your doctors and hospitals. Make a list and confirm they're in a plan's network before anything else.
- Check your prescriptions. Run your medications against each plan's formulary — the same drug can cost very different amounts from one plan to the next.
- Compare total cost, not just premium. A $0-premium plan can still cost more once you factor in copays and your out-of-pocket maximum.
- Review every year. Networks and formularies change annually, especially in fast-growing DFW counties, so the best plan last year may not be the best this year.
