Small Employer Health, ACA, and HMOs

Texas small employer health insurance (TIC Chapter 1501; TAC § 26.8)

Texas defines a “small employer” under TIC 1501.002(14) as a person who employed an average of at least 2 but not more than 50 employees on business days during the preceding calendar year, and who employs at least 2 employees on the first day of the plan year. Small-employer plans are subject to several consumer-protection mechanics:

• Guaranteed availability (TIC 1501.151). A small-employer carrier must issue the plan a small employer chooses to any small employer that elects coverage and agrees to the plan’s other requirements, such as participation and contribution, without regard to health status.
• Initial enrollment — 31 days (TIC 1501.156). Employees and dependents have at least 31 days from eligibility to enroll, plus a 31-day annual open enrollment.
• Waiting period — 90-day max. A small employer may impose a waiting period of no more than 90 days from the first day of employment (TIC 1501.156(b)); federal law sets the same 90-day ceiling for every group health plan (42 U.S.C. 300gg-7).
• Late enrollees. Employees who decline initial coverage may be excluded until the next annual open enrollment (TIC 1501.156(d)). Federal law bars a group health plan or health insurer from imposing any preexisting condition exclusion (42 U.S.C. 300gg-3), so a late enrollee’s coverage cannot exclude a preexisting condition.
• Guaranteed renewability (TIC 1501.108). A small-employer carrier must renew coverage at the employer’s option, with limited exceptions: nonpayment of premium, fraud or intentional misrepresentation of a material fact, noncompliance with the plan’s terms (such as participation requirements), no enrollee living or working in the carrier’s service area, or the end of the employer’s membership in an association through which it was covered.
• Participation and contribution (TAC § 26.8). TDI’s rule on guaranteed issue and on the employer contribution and employee participation requirements a carrier may apply.

The Affordable Care Act in Texas

Texas relies on the federal Health Insurance Marketplace (HealthCare.gov) rather than operating its own state-based exchange: it is not among the state-based exchanges CMS lists for plan year 2026. Texas residents who buy individual coverage on the Marketplace go through HealthCare.gov, and essential health benefits apply to non-grandfathered individual and small-group plans.

• Marketplace (ACA Section 1321). Federally facilitated in Texas.
• Premium tax credits and cost-sharing reductions (ACA Sections 1401 and 1402). The premium tax credit (26 U.S.C. 36B) helps eligible people who buy a plan through the Marketplace pay its premium; cost-sharing reductions lower out-of-pocket costs for eligible enrollees. Under current federal law the credit goes to households with income from 100 to 400 percent of the federal poverty line; a temporary rule lifted the 400 percent cap for 2021 through 2025 (26 U.S.C. 36B(c)(1)).
• Medicaid expansion. Texas has not adopted the ACA’s optional expansion of Medicaid to low-income adults. An adult whose income is below the federal poverty line and who does not qualify for Texas Medicaid falls into a coverage gap, because the premium tax credit starts at 100 percent of the poverty line.
• Essential health benefits (ACA Section 1302, 42 U.S.C. 18022). Ten categories, including emergency services, hospitalization, maternity and newborn care, mental health and substance use disorder services, prescription drugs, preventive and wellness services, and pediatric services (including oral and vision care). Separately, recommended preventive services are covered in network without cost sharing (42 U.S.C. 300gg-13).
• Employer notification responsibilities (ACA Sections 1511–1515). The notice requirement is ACA section 1512 (29 U.S.C. 218b): an employer covered by the Fair Labor Standards Act must give each new employee written notice of the Marketplace and of the employee’s possible eligibility for a premium tax credit.

Health maintenance organizations in Texas (TIC Chapter 843; TIC Chapter 1271; TAC Chapter 11)

Texas regulates HMOs under a distinct statutory chapter (TIC 843) and a parallel administrative rules chapter (TAC Chapter 11). Four HMO-specific topics are tested:

Evidence of coverage (TIC 843.002, 1271.002–.003; TAC § 11.501)

In an HMO, the document each enrollee is entitled to is called an Evidence of Coverage (EOC), and an EOC is not a health insurance policy (TIC 1271.002, 1271.003). The EOC must include defined disclosures: covered services, benefits, copayments and deductibles, exclusions and limitations, the network of providers, prior authorization requirements, complaint and appeal procedures, and continuation of coverage rights. TAC § 11.501 sets the minimum content requirements; the EOC must be filed with TDI for review.

Nonrenewal and cancellation (TIC 843.208; TAC § 11.506)

An HMO may cancel or refuse to renew an enrollee’s coverage only for failure to pay the charges for the coverage or for another reason the Commissioner’s rules allow (TIC 843.208). The rules list those reasons and the written notice each requires: for example, fraud or intentional misrepresentation of a material fact, fraud in the use of services or facilities, the subscriber no longer living, residing, or working in the service area, or the HMO’s discontinuing a particular type of coverage uniformly (TAC § 11.506).

Enrollment

Group HMO coverage, like any group health plan, must offer special enrollment to an eligible employee or dependent who loses other coverage, and to a person who becomes a dependent through marriage, birth, or adoption (42 U.S.C. 300gg-3(f)). For a small employer plan, the initial enrollment period is at least 31 days, with a 31-day open enrollment period each year (TIC 1501.156).

Out-of-network claims (TAC § 11.1611)

HMOs are network-based — services from non-network providers generally are not covered. There are critical exceptions:

• Emergency services. An HMO must cover emergency care, including a screening examination and the treatment and stabilization of an emergency medical condition, and must pay a non-network physician or provider for emergency care at the usual and customary rate or an agreed rate (TIC 1271.155).
• No in-network availability. If medically necessary covered services are not available through network physicians or providers, the HMO, on a network physician’s request, must allow a referral to a non-network physician or provider and fully reimburse that provider at the usual and customary rate or an agreed rate (TIC 1271.055).
• Continuity of care. When a physician or provider leaves the network for a reason other than medical competence or professional behavior, the HMO must keep paying that provider, for a limited period, to continue treating an enrollee with a special circumstance — a disability, an acute condition, a life-threatening illness, or a pregnancy past the 24th week (TIC 843.362).

TAC § 11.1611 supplies the procedural and billing rules for out-of-network claims. The federal No Surprises Act, part of the Consolidated Appropriations Act, 2021, applies to plan years beginning on or after January 1, 2022, and layers on additional protections against balance billing in defined situations.

CORE IDEA — HMOs trade choice for cost

The HMO bargain: lower premiums and tighter network in exchange for cost-sharing rules that work only inside the network. The exam loves the exception fact patterns — emergency, no in-network availability, continuity of care — where Texas law requires the HMO to cover services even outside the network.
