What Domain 13 Actually Tests
The Texas Life and Health Insurance licensing exam is organized into thirteen domains. The first nine cover general Life and Health knowledge applicable nationwide. Domains 10 through 13 are Texas-specific, and Domain 13 stands alone: Texas Statutes and Rules Pertinent to Health Maintenance Organizations (HMOs).
This domain does not simply ask you to recall what an HMO is in the abstract. It tests your working knowledge of the Texas Insurance Code provisions, Texas Department of Insurance (TDI) regulations, and the specific rights and obligations that apply when a licensed agent sells, services, or explains an HMO product to a Texas consumer. Every question in this domain requires you to think like a Texas-licensed agent operating under state law - not just a generic health insurance professional.
Domain 13 pairs naturally with Domain 12 (Texas Statutes and Rules Pertinent to Accident and Health Insurance Only) and Domain 10 (Texas Statutes and Rules Common to Life and Health Insurance). If you have already worked through those domains, you have important context. But HMO law in Texas has its own framework, its own vocabulary, and its own consumer protection structure that you must master independently.
How Texas Defines an HMO
The Statutory Definition
Under the Texas Health Maintenance Organization Act, an HMO is an entity that delivers or arranges for the delivery of basic health care services to enrollees on a prepaid basis. The prepaid nature is fundamental - enrollees pay a fixed periodic premium in exchange for comprehensive services, rather than paying per service as they would under a traditional indemnity plan.
Texas law requires that an HMO provide or arrange for basic health care services, which typically include physician services, inpatient hospital services, outpatient medical services, emergency care, and preventive services. The scope of what constitutes "basic" services is defined in statute, and the exam tests whether you can identify what must be included versus what is permissible as an optional supplemental benefit.
Enrolled vs. Covered
Texas HMO statutes use the term enrollee rather than "insured" or "policyholder." This terminology distinction appears on the exam. An enrollee is an individual who has enrolled in the HMO plan and is entitled to receive services. A group contract holder - such as an employer - is distinct from the enrollee. Understanding which rights and obligations attach to each party is a tested concept.
Domain 13: Core Definitional Concepts to Master
The exam expects you to identify and apply these HMO-specific terms accurately under Texas law.
- HMO (Health Maintenance Organization) - prepaid, comprehensive care model
- Enrollee - the individual entitled to receive HMO services
- Basic health care services - the minimum package an HMO must offer
- Primary Care Physician (PCP) - gatekeeper role and referral requirements
- Service area - the geographic boundary within which the HMO provides coverage
- Evidence of Coverage - the document replacing a traditional insurance policy
HMO Licensure and Certificate of Authority
Certificate of Authority Requirement
No entity may operate as an HMO in Texas or enroll Texas residents without first obtaining a Certificate of Authority (COA) from TDI. This is not optional and is not a formality. Operating without a COA exposes an entity to significant regulatory penalties. For the exam, you should know that the COA is the operative license for the HMO entity itself - it is separate from the individual agent license you are working toward.
TDI evaluates applications for a COA based on the applicant's financial condition, organizational structure, network adequacy, and ability to deliver the promised services. The exam may present scenarios in which you must determine whether a described entity is required to hold a COA or whether its activities fall outside HMO regulation.
Agent Licensing in the HMO Context
Individual agents who sell HMO products in Texas do so under their Life & Health license - the same license you are studying for now. There is no separate "HMO agent license" in Texas. This means the L&H license you earn grants you authority to sell HMO products, provided you understand the additional regulatory requirements that apply specifically to those products.
This has a practical implication for exam questions: when a scenario describes an agent selling an HMO enrollment, the question may test whether the agent's L&H license covers that activity (it does), or whether the agent is subject to HMO-specific disclosure obligations (they are). Both answers flow from Domain 13.
Enrollee Rights and Protections
Texas law grants HMO enrollees a robust set of rights that are more detailed and specific than the general health insurance consumer protections tested in Domain 12. The exam focuses heavily on these rights because they define what a compliant HMO must provide and what an agent must communicate to prospective enrollees.
Right to Choose and Change a PCP
Texas HMO enrollees have the right to choose a Primary Care Physician from within the HMO's participating provider network. They also have the right to change their PCP, subject to procedural requirements set by the HMO. The exam may test the timeline and process for changing a PCP, as well as the circumstances under which an HMO may limit a change.
Right to Emergency Care
Texas law requires HMOs to cover emergency care services even when the enrollee receives that care from a non-network provider. The "prudent layperson" standard applies: if a reasonable person with average health knowledge would believe the situation was an emergency, the HMO must cover it. This standard overrides strict network requirements in emergency situations and is a frequently tested concept.
Right to Independent Review
When an HMO denies, reduces, or terminates a covered service, the enrollee has the right to request an independent review by an independent review organization (IRO) that is not affiliated with the HMO. Texas was among the first states to establish this right in statute, and TDI maintains oversight of the IRO process. Exam questions on this topic often focus on which adverse determinations trigger the right to independent review and the timelines involved.
Enrollee Rights: High-Frequency Exam Topics
These rights appear regularly in Domain 13 scenario questions. Know the statutory basis for each.
- Right to select and change a PCP within the network
- Right to emergency care under the prudent layperson standard
- Right to independent review of adverse determinations
- Right to receive the Evidence of Coverage document
- Right to continuity of care when a provider leaves the network
- Right to appeal grievances through the HMO's internal process before external review
Provider Networks and Access Standards
Network adequacy is one of the defining features of HMO regulation and a topic that distinguishes Domain 13 from the general health insurance content in Domain 5 (Accident and Health - Types of Policies). An HMO must maintain a network of participating providers that is sufficient in number and geographic distribution to deliver all covered basic health care services to enrollees in the HMO's service area.
Service Area and Out-of-Area Coverage
Every Texas HMO operates within a defined service area - the geographic region where it has established a provider network and within which it accepts enrollees. Outside the service area, the HMO generally has no obligation to cover non-emergency services. This creates important exam scenarios: an enrollee who moves outside the service area, or who travels and requires non-emergency care, is typically not covered for routine services.
Continuity of Care
When an enrollee is in the middle of an active course of treatment and their provider leaves the HMO network, Texas law provides a right to continuity of care - the ability to continue treatment with that provider for a transitional period, subject to statutory limits. This protection prevents abrupt disruptions in care and is tested as part of the broader network adequacy framework.
Grievance and Appeals Procedures
Texas HMO law establishes a structured grievance and appeals process that enrollees must follow before accessing external review. Understanding the sequence and timelines in this process is essential for Domain 13 questions.
| Step | Process | Key Feature |
|---|---|---|
| 1 | Internal Grievance | Enrollee submits complaint to HMO; HMO must respond within statutory timeframe |
| 2 | Internal Appeal | Formal review of adverse determination by HMO's appeals committee |
| 3 | Independent Review (IRO) | External review by TDI-approved IRO; binding on the HMO for clinical decisions |
| 4 | TDI Complaint | Enrollee may file complaint with TDI for regulatory review of HMO conduct |
The exam tests whether candidates can identify which step an enrollee is at based on a scenario description, and what the HMO's obligations are at each stage. Pay particular attention to the distinction between a grievance (any complaint about the HMO's conduct or service) and an appeal (a formal challenge to a specific adverse coverage determination).
Key Takeaway
Independent review by an IRO is a right triggered by adverse clinical determinations - not by billing disputes or administrative complaints. Knowing which category a scenario falls into determines the correct regulatory response under Texas HMO law.
Agent Responsibilities in HMO Sales
Domain 13 does not exist in isolation from the other Texas-specific domains. When you sell an HMO product, you are simultaneously subject to the general agent conduct rules in Domain 10 and the HMO-specific obligations in Domain 13. Understanding where these overlap - and where Domain 13 adds requirements - is a sophisticated skill the exam rewards.
Required Disclosures
Before enrollment, an agent must ensure that the prospective enrollee understands the HMO's service area, the requirement to use network providers, the PCP selection process, and the procedures for obtaining referrals to specialists. These are not optional disclosures - they are legally required elements of a compliant HMO sales interaction. Exam questions often present a scenario where an agent fails to make one of these disclosures and ask you to identify the regulatory violation.
Evidence of Coverage Delivery
Unlike a traditional insurance policy, an HMO provides enrollees with an Evidence of Coverage (EOC) document rather than a policy in the conventional sense. The EOC describes benefits, limitations, exclusions, and the procedures the enrollee must follow to access care. Agents should understand that the EOC is the governing document for the enrollee's rights - and that TDI must approve the EOC before it can be issued to Texas enrollees.

HMO vs. Traditional Insurance: Key Distinctions for the Exam
A significant portion of Domain 13 questions tests your ability to distinguish HMO-specific rules from the general accident and health insurance rules you learned in Domains 5 through 9. The following comparison captures the most frequently tested distinctions.
| Feature | Traditional (Indemnity) Plan | Texas HMO |
|---|---|---|
| Governing document | Insurance policy | Evidence of Coverage (EOC) |
| Provider choice | Any licensed provider | Network providers only (except emergencies) |
| Payment model | Fee-for-service reimbursement | Prepaid, capitation or salary arrangements |
| Geographic scope | Typically nationwide | Defined service area |
| Regulatory license (entity) | Certificate of Authority (insurer) | Certificate of Authority (HMO-specific) |
| Dispute resolution | Internal appeals, state complaint | Internal grievance → IRO → TDI complaint |
Fitting Domain 13 Into Your Study Plan
Because Domain 13 is Texas-specific and statute-heavy, it benefits from being studied after - not before - you have a solid foundation in the general health insurance concepts from Domains 5 through 9. The HMO rules make more intuitive sense when you already understand how traditional health insurance works and can identify what the HMO framework changes or supplements.

Frequently Asked Questions
No. Your Texas Life & Health license authorizes you to sell HMO products. There is no separate HMO agent license in Texas. However, you must understand the HMO-specific regulatory requirements covered in Domain 13, because those obligations apply to you when you sell these products.
A grievance is any complaint an enrollee files with the HMO about services, conduct, or administration. An appeal is a formal challenge to a specific adverse determination - a denial, reduction, or termination of a covered service. Appeals follow a defined statutory process that can culminate in independent review by a TDI-approved IRO.
Texas law requires the HMO to cover emergency services regardless of whether they are provided by a network provider and regardless of geographic location. The prudent layperson standard applies: if a reasonable person would have believed it was an emergency, the HMO must cover the care. Non-emergency out-of-area services are generally not covered.
The Evidence of Coverage (EOC) is the governing document that describes an HMO enrollee's rights, benefits, limitations, and procedures for accessing care. It functions similarly to a policy but uses HMO-specific terminology and must be approved by TDI before issuance. The term "enrollee" replaces "insured," and the document reflects the prepaid, network-based nature of HMO coverage.
Domain 13 is one of four Texas-specific domains (Domains 10-13) on the exam. While the exact weighting is not published in the publicly available exam outline, the Texas-specific domains collectively represent a substantial portion of the state-law section. Because HMO products are widely sold in Texas, TDI treats Domain 13 as a core competency for licensed agents - not a minor topic.
