Health Insurance in Port Arthur, Texas — The Largest Refinery and the Coverage Gap

Updated March 2026 · Southern Plan Finder — Licensed Health Insurance Agency · (877) 224-8539

Port Arthur is an industrial city on the Texas Gulf Coast best known for one thing: the Motiva Enterprises refinery — the largest oil refinery in North America, with a capacity of over 600,000 barrels per day. The city's approximately 56,000 residents live in one of the most diverse small cities in the United States, with significant African American, Vietnamese, and Hispanic populations. Port Arthur's economy revolves almost entirely around the petrochemical industry, and its health insurance landscape is defined by the gap between direct refinery employees with benefits and the broader community that depends on the ACA marketplace.

Port Arthur also illustrates one of the sharpest state-line health insurance contrasts on the Gulf Coast. Lake Charles, Louisiana — just 60 miles east — sits in a state that expanded Medicaid in 2016. Port Arthur sits in Texas, which has not expanded Medicaid. A low-income refinery contractor living in Port Arthur falls into a coverage gap that the same person living in Lake Charles would not face.

Healthcare in Port Arthur

The Medical Center of Southeast Texas in Port Arthur provides local acute care and emergency services. For specialist care, advanced diagnostics, and many surgical procedures, Port Arthur residents typically travel to Beaumont — approximately 20 miles north — where Baptist Hospitals of Southeast Texas and Christus Southeast Texas provide broader services.

When choosing an ACA plan, ensure your network covers both The Medical Center locally and the Beaumont hospitals you would use for referral care. For the most complex cases, Houston's Texas Medical Center is approximately 90 miles west.

Motiva Refinery and the Contract Workforce

The Motiva refinery dominates Port Arthur's economy. Valero and Total Energies also operate significant refining capacity in the area. The health insurance divide in Port Arthur is stark:

Refinery Employment and Insurance Direct employees of Motiva, Valero, and Total typically have comprehensive employer-sponsored health insurance. The contractor workforce — turnaround crews, maintenance workers, scaffolders, insulation workers, sandblasters, and crane operators — often lacks employer coverage. During major turnarounds, the contractor population in Port Arthur can swell by thousands. These workers are the core of the local ACA marketplace population and may qualify for substantial premium tax credits.

The Texas-Louisiana Border

Texas Coverage Gap vs. Louisiana Medicaid Port Arthur is 60 miles from Lake Charles, Louisiana. Louisiana expanded Medicaid — residents below 138% FPL qualify for Medicaid coverage. Texas has NOT expanded Medicaid — Port Arthur residents at the same income fall into a coverage gap with no subsidized option. A refinery contractor earning $14,000/year in Port Arthur has no Medicaid eligibility and no ACA subsidy. The same worker living in Lake Charles would qualify for Louisiana Medicaid. This is one of the starkest health insurance disparities along any state border in the US.
