If you have compared Medicare Advantage notes with a friend across town and found that you were looking at different plans, you have run into the county rule. Medicare Advantage plans are approved and sold by county, and Texas has 254 of them. This guide explains why that is, what it means in the big Texas metros and in rural areas, what to check before you enroll, and how a licensed agent who knows your county can help at no cost.
Key takeaways
- Every Medicare Advantage plan has a service area defined by county. Your options depend on where you live, not just your state.
- Houston, Dallas-Fort Worth, San Antonio, Austin, and El Paso typically have many plans and several competing hospital networks. Rural counties have fewer.
- Check your doctors, your hospital, your prescriptions, and the plan's out-of-pocket maximum before the premium.
- If you move to a county outside your plan's service area, you get a Special Enrollment Period.
- A licensed agent can pull every plan in your county from the carriers they represent and check your providers against each one.
What Medicare Advantage is
Medicare Advantage, also called Part C, is a way to get your Medicare benefits through a private insurance plan approved by Medicare. The plan covers everything Part A and Part B cover, usually includes Part D drug coverage, and often adds benefits Original Medicare does not, such as dental, vision, hearing, or fitness programs. In exchange, you typically use the plan's network and follow its rules, such as referrals or prior authorization.
You still pay your Part B premium, and the plan may charge its own premium on top. Your costs then depend on the care you use, up to a yearly out-of-pocket maximum that Original Medicare does not have. The full comparison with the other path is in Medicare Advantage vs. Medigap.
Why plans are sold by county
Insurers apply to Medicare each year with a proposed service area, listed county by county, and a provider network that meets Medicare's access standards in each of those counties. Medicare reviews and approves the plan for that area only. The result:
- A plan can be offered in Harris County but not in Fort Bend or Montgomery County next door.
- A plan with the same name can have a different premium, copays, and extra benefits in different counties.
- Star ratings, which measure quality and member experience, apply to the plan contract, which may span many counties.
This is why the Medicare Plan Finder asks for your ZIP code and sometimes your county before showing anything. It is also why advice from someone in another county, however well meant, needs to be checked against your own list.
Big metros versus rural Texas
In the largest Texas metros, Medicare Advantage is highly competitive. That is good for choice, but it also means more homework.
| Where you live | What to expect | The key question |
|---|---|---|
| Houston and Harris County | Many plans, several large hospital systems, networks often built around one system | Which hospital system is my doctor part of, and is it in this plan's network? |
| Dallas-Fort Worth | Many plans across Dallas, Tarrant, Collin, and Denton counties; lineups differ by county | Is the plan I like offered in my county, and does it include my specialists? |
| San Antonio and Bexar County | Broad lineup, strong HMO presence, many Special Needs Plans | Do I qualify for a Special Needs Plan, and does the HMO include my clinic? |
| Austin and Travis County | Competitive but with networks that can differ sharply between plans | Does the plan include the practice I already use? |
| El Paso | Distinct market with its own hospital systems and cross-county considerations | Does the network cover care on both sides of the county line I use? |
| Rural counties | Fewer plans, sometimes only PPOs or a single HMO, smaller networks | Is my local hospital in network, and what happens if I need care in a city? |
In a metro, the danger is choosing a plan built around the wrong hospital system. In a rural county, the danger is a network that does not include the nearest hospital or that forces long drives for specialists.
Plan types you will see
- HMO. You choose a primary care doctor and generally need referrals to see specialists. Out-of-network care is not covered except in emergencies. Often the lowest premiums.
- HMO-POS. An HMO with limited out-of-network options for certain services.
- PPO. You can see out-of-network providers, usually at a higher cost. Helpful if you travel or split time between Texas and another state.
- Special Needs Plans (SNPs). Plans designed for people with both Medicare and Medicaid (D-SNPs), specific chronic conditions (C-SNPs), or those living in institutions. D-SNPs are common in Texas metros and often include extra benefits for people who qualify.
- Private Fee-for-Service. Less common; you can see any provider who accepts the plan's terms.
What to check before you enroll
Work through this list for each plan on your short list. The order is deliberate: the premium comes last.
- Your doctors. Search the plan's directory for each doctor and specialist, then call the office and ask, "Are you in network for this specific plan next year?" Directories can be out of date.
- Your hospital. Confirm the hospital you would want to use for surgery or an emergency is in network.
- Your prescriptions. Check the plan's formulary, the tier of each drug, and whether your pharmacy is preferred. See how to compare Part D plans.
- Out-of-pocket maximum. This is your worst-case yearly cost for covered medical services. Compare it across plans.
- Prior authorization and referrals. Ask which services need approval. This affects how quickly you get care.
- Extra benefits. Dental, vision, hearing, over-the-counter allowances, and transportation vary widely. Read the limits, not just the headline.
- Star rating. Medicare rates plans from one to five stars. A five-star plan can be joined during a special window once a year.
- Premium. Only after the above. A zero-premium plan is not free if its network excludes your cardiologist.
Enrollment windows
- Initial Enrollment Period. The seven months around your 65th birthday month.
- Annual Enrollment Period. October 15 to December 7 for coverage starting January 1.
- Medicare Advantage Open Enrollment Period. January 1 to March 31, when people already in Medicare Advantage can switch to another plan once or return to Original Medicare.
- Special Enrollment Periods. Moving out of your plan's service area, losing employer coverage, your plan leaving your county, and other events.
One Texas-specific caution: if you leave Medicare Advantage and want a Medigap policy, insurers in Texas can ask health questions unless you have a guaranteed-issue right. The trial right protects you if you joined Medicare Advantage when you first became eligible and leave within the first year. Read Medicare in Texas for the details.
How an agent helps with county-level choices
A licensed Medicare agent who works your county knows which hospital systems anchor which networks, which plans have had provider disputes, and how the lineups change from year to year. Specifically, an agent can:
- Pull every plan in your county from the carriers they are appointed with
- Check each of your doctors and drugs against those plans
- Explain the trade-offs between an HMO with lower costs and a PPO with travel flexibility
- Complete the Scope of Appointment and enrollment paperwork
- Review your plan with you every fall, since benefits and networks change
Agents are paid by the carriers, so this help does not add to your premium. Ask which carriers they represent in your county, and verify their license before you share your Medicare number. You can browse Medicare agents in Texas, including Houston, Dallas, Fort Worth, San Antonio, Austin, and El Paso. Free, unbiased counseling is also available through Texas's State Health Insurance Assistance Program.
Talk to a licensed agent for free
Medicare agents are paid by the insurance carriers whose plans they sell, so you pay nothing extra for their time, and your premium is the same either way. A licensed Texas agent can compare the Medicare Advantage plans in your county, check your doctors and prescriptions against each one, and help you enroll before the deadline. When you are ready, you can find a licensed health insurance agent near you and get connected at no cost.
Frequently asked questions
Why are Medicare Advantage plans different from one Texas county to the next?
Each plan has a service area approved by Medicare, defined by county. Insurers choose which counties to serve and build a provider network for each. A plan in Harris County may not be offered in a neighboring county, and the same plan name can have different benefits in different counties.
How do I see which Medicare Advantage plans are available where I live?
Use the Medicare Plan Finder on Medicare.gov and enter your ZIP code. If your ZIP code spans more than one county, it will ask which county you live in. A licensed agent can also pull the list for your county.
What happens to my Medicare Advantage plan if I move to another county in Texas?
If your new county is outside the plan's service area, you get a Special Enrollment Period to pick a new plan or return to Original Medicare. Tell the plan as soon as you know your move date.
Are there fewer Medicare Advantage options in rural Texas?
Usually, yes. Rural counties tend to have fewer plans and smaller networks than Houston, Dallas-Fort Worth, San Antonio, Austin, or El Paso. In some rural areas, checking that the local hospital is in network is the single most important step.
Can I go back to Medigap if Medicare Advantage does not work out?
You can return to Original Medicare during the Annual Enrollment Period or the Medicare Advantage Open Enrollment Period, but buying a Medigap policy may require health underwriting in Texas unless you have a guaranteed-issue right, such as the trial right during your first year in Medicare Advantage.
