Health Insurance in Hidalgo County, Texas: 2026 Marketplace Guide

Updated July 2026 · Texas-Plans.com — Licensed Health Insurance Producer (NPN #21249133)

Hidalgo County is one of the most active ACA marketplace counties in the United States. With a population of approximately 914,820 — making it the ninth most populous county in Texas — and 200,636 marketplace enrollees in 2025, it ranks fifth in Texas for total ACA enrollment despite its ranking ninth by population, according to Texas Tribune reporting from December 2025. Approximately 98% of those enrollees received premium tax credits, and roughly 70% paid $10 or less per month in premiums. These figures reflect the county's income profile: a median household income of approximately $52,281, an unemployment rate consistently above state and national averages, and a population that is 91.9% Hispanic or Latino with 26% born outside the United States. Despite this enrollment activity, the county's uninsured rate remains approximately 28% — among the highest of any large U.S. county — driven primarily by immigration-related coverage restrictions and Texas's decision not to expand Medicaid. In 2026, three carriers offer marketplace plans in Hidalgo County's McAllen ACA rating area.

What Hidalgo County Residents Most Often Get Wrong About Health Coverage

The most consequential misunderstanding in Hidalgo County involves eligibility boundaries. Because 26% of the county's population was born outside the United States, many households include members with different immigration statuses — and different eligibility rules. U.S. citizens and lawfully present immigrants are eligible for ACA marketplace plans and, if income qualifies, for premium tax credits. Undocumented immigrants are not eligible for marketplace plans or subsidies, though their citizen or lawfully present family members remain eligible. Mixed-status households must apply for coverage on behalf of the eligible members only; the presence of an ineligible household member does not prevent eligible members from enrolling.

A second widespread error involves Medicaid. Texas has not expanded Medicaid under the Affordable Care Act. Adults between ages 19 and 64 without dependent children are not eligible for Medicaid in Texas regardless of income. With a median household income of approximately $52,281 and a poverty rate substantially above the Texas average, many Hidalgo County residents fall in the income range where expanded Medicaid would apply in other states. Those who earn below 100% of the federal poverty level and do not have qualifying dependent children face the Texas coverage gap: no Medicaid access and no marketplace premium tax credit eligibility. For the portion of the county's uninsured population that falls in this range, no subsidized coverage pathway currently exists under Texas law.

The 2026 carrier landscape in Hidalgo County also changed significantly from prior years. Molina Healthcare — which had been one of the active marketplace carriers in the Rio Grande Valley — exited Hidalgo County and other Valley counties for the 2026 plan year. Residents who were enrolled in Molina plans needed to actively select a replacement carrier during open enrollment. Those who did not re-enroll may have been auto-assigned to an alternative plan but should verify their current coverage status.

Step-by-Step: Finding Coverage in Hidalgo County

Step 1 — Confirm eligibility for each household member separately. In Hidalgo County's mixed-status households, eligibility must be evaluated for each person individually. U.S. citizens and qualifying immigrants are eligible to enroll. When applying, include income from all household members but only request coverage for those who are eligible. Inaccurate household composition or income reports can create repayment obligations at tax time.

Step 2 — Estimate annual household income carefully. Many Hidalgo County households include self-employed individuals, agricultural workers, and informal-sector workers whose income varies seasonally. Use projected annual net income — not gross receipts — when applying for marketplace coverage. If income is genuinely uncertain, a conservative estimate prevents an unexpectedly large tax-time repayment, but understating income artificially creates its own risks if actual income comes in higher.

Step 3 — Review the three confirmed carriers for 2026. Ambetter, Blue Cross and Blue Shield of Texas, and UnitedHealthcare are the confirmed marketplace carriers in the McAllen rating area for 2026. Compare plan tiers, networks, and premiums (after applying your estimated premium tax credit) for all three before selecting a plan. The loss of Molina Healthcare from this market means residents who were previously enrolled in Molina should evaluate all three remaining options rather than defaulting to the plan closest to their prior coverage.

Step 4 — Verify your preferred providers and hospitals. South Texas Health System McAllen — a Level I Trauma Center and major acute care facility — and DHR Health (Doctors Hospital at Renaissance) in Edinburg are two of the county's primary hospital systems. Before enrolling, use each carrier's provider directory to confirm your preferred hospitals and any current specialist relationships are covered in-network.

Step 5 — Enroll November 1 through January 15. Federal marketplace open enrollment runs annually from November 1 through January 15. Coverage beginning January 1 requires enrollment by December 15. Loss of Medicaid (for those who had it), loss of employer coverage, or change in immigration status to a qualifying category are all events that may trigger a Special Enrollment Period outside the standard window.

Health Insurance Carriers in Hidalgo County

In 2026, three carriers offer marketplace plans in Hidalgo County's McAllen ACA rating area: Ambetter, Blue Cross and Blue Shield of Texas, and UnitedHealthcare. This represents a reduction from prior years following Molina Healthcare's exit from the Rio Grande Valley for the 2026 plan year — a change that directly affected the carrier options available to Hidalgo County's large marketplace enrollment population.

Ambetter, administered by Superior HealthPlan, has been one of the larger marketplace carriers in South Texas, offering HMO plans with networks built around the Rio Grande Valley's provider community. Blue Cross and Blue Shield of Texas offers its statewide Blue Advantage HMO network, which includes providers throughout the McAllen–Edinburg–Mission metropolitan area. UnitedHealthcare explicitly identifies Hidalgo County within its South Texas service area, covering Hidalgo, Cameron, Starr, and several other adjacent counties.

For Hidalgo County's 200,000-plus marketplace enrollees, the shift from four to three confirmed carriers is meaningful — it reduces premium competition and removes a plan option that some residents had chosen specifically for its network or price point. Residents who were previously enrolled in Molina plans should compare the three remaining carriers carefully, including running provider directory checks for their current doctors, clinics, and specialists.

South Texas Health System McAllen (owned by Universal Health Services) serves as a Level I Trauma Center and Comprehensive Stroke Center for the region. DHR Health, a physician-owned health system headquartered in Edinburg, operates a full-service regional hospital and specialty institutes across the McAllen metro. Network access to both systems should be verified against your chosen plan's provider directory, as these are the county's primary acute care resources. Plan types in Hidalgo County are HMO and EPO — PPO plans are not available on the Texas federal marketplace.

Common Mistakes to Avoid in Hidalgo County

Not re-enrolling after Molina Healthcare's exit. Residents who were enrolled in Molina Healthcare plans and did not actively re-enroll during the 2025-26 open enrollment period should verify their current coverage status immediately. Automatic reassignment to another plan is not guaranteed to have selected the plan that best matches your providers, premium preferences, or cost-sharing needs.

Assuming all household members are covered under one application. In mixed-immigration-status households, each eligible member must be properly included in the marketplace application and each ineligible member excluded. Including ineligible members in a coverage application creates legal compliance issues. The eligible members of any household retain full marketplace access regardless of other members' immigration status.

Reporting income incorrectly for seasonal or informal work. Hidalgo County's agricultural and informal-sector workers often have seasonal income patterns. Failing to accurately project annual income — by using only peak-season earnings or only a partial year of work — can result in a tax-time repayment obligation if actual annual income exceeds the enrollment estimate. For workers with highly seasonal income, working with a navigator or licensed enrollment broker helps ensure accurate projection.

Missing the Special Enrollment Period when circumstances change. In a county with high immigrant and agricultural worker populations, life circumstances change frequently. Loss of employer coverage, a qualifying change in immigration status, or a household member turning 26 are all qualifying events that open a 60-day Special Enrollment Period. These windows matter in a county where many residents are uninsured — missing a Special Enrollment Period means waiting until the next open enrollment period with no coverage in between.
