Dallas Insurance Claim Denied? Your Rights and How to Appeal

Dallas is one of the largest cities in the United States and a major economic center — home to American Airlines, AT&T, Bank of America's operations hub, Toyota's North American headquarters, and scores of Fortune 500 companies. The city's economy spans finance, technology, telecommunications, healthcare, and retail. Dallas is also home to UT Southwestern Medical Center, Baylor Scott & White Health, Parkland Health, and Texas Health Resources — four major health systems that together serve millions of patients across the DFW metroplex. Blue Cross Blue Shield of Texas is the dominant commercial insurer in the area, with Aetna, UnitedHealthcare, Cigna, and Humana serving large employer groups. Many of Dallas's major corporate employers self-fund their health plans under ERISA. Texas Medicaid managed care and ACA marketplace plans cover residents without employer coverage.
