Comparing Medicare plans in Texas
Medicare Advantage (also known as Medicare Part C) is a bundled, all-in-one alternative to Original Medicare, offered by private insurance companies approved by the federal government. If you live in Texas and are eligible for Medicare, a Medicare Advantage plan replaces the way you receive your Part A (hospital) and Part B (medical) benefits, wraps them into a single plan, and typically includes Part D prescription drug coverage. Most plans also layer on additional benefits that Original Medicare does not cover, such as dental, vision, hearing, and fitness memberships. The trade-off for these bundled benefits is that you must agree to follow the plan’s specific rules, use their established network of local doctors and hospitals, and often navigate a different cost-sharing structure than you would under the traditional government program.
Navigating Medicare in Texas is a major financial and healthcare decision. This comprehensive guide serves as the foundation for understanding what Medicare Advantage is, how it operates under Centers for Medicare & Medicaid Services (CMS) regulations, the landscape of carriers operating in the state, and how to determine if Part C is the right structural fit for your health and budget.
To understand Medicare Advantage, you must first understand the baseline it replaces. Original Medicare is administered directly by the federal government and is split into two primary parts:
Original Medicare has significant gaps. It covers roughly 80% of approved medical costs, leaving you responsible for the remaining 20% with absolutely no annual cap on your out-of-pocket spending. Furthermore, it does not cover prescription drugs (which require a separate Part D plan), nor does it cover routine dental, vision, or hearing care.
Medicare Advantage (Part C) was created to provide a private-market alternative to this system. When you enroll in a Medicare Advantage plan in Texas, you are still officially in the Medicare program, and you still have the exact same rights and protections. However, instead of the government paying your doctors directly when you receive care, the government pays the private insurance company a set monthly fee to manage your care. The insurance company then pays your providers according to the terms of your specific plan.
By law, every Medicare Advantage plan must cover everything that Original Medicare Part A and Part B cover. The difference lies in how they cover it (copays vs. coinsurance), the networks you are required to use, and the extra benefits they bundle in to attract enrollees.
Texas has one of the largest, most competitive, and most diverse Medicare Advantage markets in the country. Because Medicare Advantage plans are offered on a county-by-county basis, the options available to a resident in urban Harris County (Houston) will look vastly different than the options available to a resident in rural Brewster County.
Across the state, there are 398 individual Medicare Advantage plans available for this plan year. This immense volume is supported by a mix of massive national insurers and highly specialized regional health systems. If you reside in Texas, your carrier options may include:
National carriers like UnitedHealthcare, Humana, and Aetna typically offer broad networks that span multiple states, which can be advantageous if you split your time between Texas and another state. Conversely, regional provider-sponsored plans like KelseyCare Advantage (in the Houston area) or Baylor Scott & White Health Plan (in Central and North Texas) are built directly around specific, highly-rated local hospital systems, often resulting in tighter care coordination.
To enroll in a Texas Medicare Advantage plan, you must meet a few strict baseline requirements set by CMS.
The decision to choose Medicare Advantage over Original Medicare (often paired with a Medicare Supplement/Medigap plan and a Part D drug plan) is the most critical fork in the road for any Medicare beneficiary.
| Feature | Original Medicare (Government) | Medicare Advantage (Private) |
|---|---|---|
| Doctor Network | Any doctor or hospital in the U.S. that accepts Medicare. No networks. | Usually restricted to a local network of contracted providers (HMO or PPO). |
| Referrals | Not required. You can see any specialist directly. | Often required (especially in HMOs) before seeing a specialist. |
| Prescription Drugs | Not included. Must buy a standalone Part D plan. | Usually bundled into the plan (MA-PD) at no extra premium. |
| Out-of-Pocket Maximum | None. You are liable for 20% of costs indefinitely. | Yes. By law, plans cap your annual medical spending, protecting you from catastrophic bills. |
| Extra Benefits | None. Does not cover routine dental, vision, or hearing. | Frequently includes dental, vision, hearing, OTC allowances, and fitness memberships. |
| Premium | You pay the standard Part B premium. | You pay the Part B premium PLUS the plan's premium (many plans charge $0). |
Understanding what a Medicare Advantage plan actually costs day-to-day requires looking past the monthly premium. The financial architecture of these plans is built around several cost-sharing mechanisms.
This is the single most misunderstood aspect of Medicare Advantage. Even if you select a Medicare Advantage plan that advertises a “$0 monthly premium,” you must continue to pay your Medicare Part B premium to the federal government. For most Texans, this premium is deducted automatically from their Social Security check. The Medicare Advantage plan’s premium (if it has one) is charged in addition to your Part B premium.
While many Texas plans offer a $0 monthly premium, others charge anywhere from $15 to over $100 per month. Plans with higher monthly premiums often offer lower out-of-pocket costs when you actually go to the doctor, or they provide vastly expanded extra benefits, such as a higher annual dental allowance.
A deductible is the amount you must pay out of pocket before the plan begins covering its share.
When you receive medical services, you will share the cost with the insurance company through either a copayment or coinsurance.
This is the most critical financial safety net in a Medicare Advantage plan. The MOOP is the absolute maximum amount of your own money you will have to spend on approved, in-network medical services during the calendar year. Once your deductibles, copayments, and coinsurance payments hit this threshold, the plan pays 100% of your covered medical costs for the rest of the year.
In Texas, MOOP limits range widely depending on the plan you choose. A plan with a $0 premium might have a MOOP of $7,500, while a plan that charges $45 a month might cap your MOOP at $3,400. Note: Prescription drug costs (Part D) do not count toward your medical MOOP.
Not all Medicare Advantage plans are structured the same way. The type of plan you choose dictates how freely you can seek care and whether your care is covered outside of your home network. Using real examples from the Texas market, here is how the primary plan architectures function.
HMOs are generally the most restrictive plan type, but they often feature the lowest monthly premiums and the richest extra benefits. In an HMO, you are required to use the plan’s specific network of doctors and hospitals for all non-emergency care. If you go outside the network, the plan will pay nothing, and you will be responsible for the entire bill.
Furthermore, HMOs typically require you to designate a Primary Care Provider (PCP). Your PCP acts as the gatekeeper for your healthcare; if you need to see a specialist (like a cardiologist or a dermatologist), you must first get a referral from your PCP.
An HMO-POS plan operates like a traditional HMO but offers slightly more flexibility by allowing you to seek certain services out-of-network, usually at a higher copayment or coinsurance rate.
Texas has a high volume of HMO-POS plans. For example, the AARP Medicare Advantage CareFlex from UHC TX-44 (HMO-POS) and the AARP Medicare Advantage Essentials from UHC TX-12 (HMO-POS) fall into this category. These plans give beneficiaries the structured, coordinated care of an HMO, but with a “safety valve” that allows them to see an out-of-network provider for specific services without footing 100% of the bill, provided they follow the plan’s rules.
PPOs offer much greater flexibility. You do not need to designate a Primary Care Provider, and you do not need referrals to see specialists. More importantly, PPOs have both in-network and out-of-network coverage for almost all services.
If you use an in-network provider, you will pay the lowest possible copayments. If you choose to see a doctor outside the network who accepts Medicare, the plan will still cover a portion of the cost, though your out-of-pocket share will be higher. The AARP Medicare Advantage Essentials from UHC EP-1 (PPO) is an example of a Texas plan that allows this broader freedom of movement, which is highly appealing to Texans who travel frequently or spend part of the year in another state.
SNPs are specialized Medicare Advantage plans designed specifically for individuals with specific diseases, characteristics, or financial situations. The benefits, provider choices, and drug formularies in these plans are tailor-made to best meet the specific needs of the groups they serve.
PFFS plans are less common today but still exist in certain parts of Texas. Instead of having a strict network, the plan determines how much it will pay doctors and how much you must pay when you get care. You can go to any Medicare-approved doctor, but the critical catch is that the doctor must agree to the plan’s payment terms every single time you receive a service.
The single biggest complaint among new Medicare Advantage enrollees usually revolves around a misunderstanding of how networks function. When you join a Medicare Advantage plan, you are trading the universal access of Original Medicare for a privatized, localized network.
A network is a contracted group of physicians, specialists, hospitals, imaging centers, and pharmacies that have agreed to provide care to the insurance company’s members at pre-negotiated rates. If your preferred doctor is in your plan’s network this year, there is no guarantee they will remain in the network next year. Contracts are renegotiated annually.
Beyond simply staying in-network, Medicare Advantage plans utilize Prior Authorization to control costs. This means that before you can undergo certain non-emergency procedures—such as an MRI, a knee replacement, or the administration of specialized Part B drugs—your doctor must submit a request to the insurance company proving the procedure is medically necessary. The insurance company then reviews the request and either approves or denies the coverage. Original Medicare rarely requires prior authorization; Medicare Advantage plans use it frequently.
The vast majority of Medicare Advantage enrollees in Texas choose a plan that includes prescription drug coverage, officially termed an MA-PD plan. By bundling your medical and drug coverage into one ID card, you avoid having to purchase a separate standalone Part D plan.
To evaluate a plan’s drug coverage, you must look at its Formulary—the official list of medications the plan agrees to cover. Formularies are typically divided into five tiers:
If a medication you take is not on the plan’s formulary, the plan will not pay for it, and you will be responsible for the full retail price unless you can secure a formal exception. Therefore, ensuring your specific prescription drugs are covered on a low tier is just as important as checking if your doctor is in-network.
Because insurance companies receive a set amount of money from the government for every person they enroll, they compete fiercely to attract seniors by offering extra benefits that Medicare does not traditionally cover. In Texas, the competition is intense, leading to incredibly robust benefit packages.
Common extra benefits include:
While these benefits are attractive, they should not be the sole reason you select a plan. A $2,000 dental allowance is not worth joining a plan if that plan does not include your critical cardiologist in its network, or if it charges a maximum out-of-pocket limit that is thousands of dollars higher than a competitor’s.
You cannot simply wake up on a Tuesday in June and decide to enroll in or switch your Medicare Advantage plan. CMS strictly governs when you are allowed to make changes to your coverage. Navigating these enrollment periods correctly is vital.
Your first opportunity to join a Medicare Advantage plan occurs when you first become eligible for Medicare. This is a 7-month window that begins three months before the month you turn 65, includes your birthday month, and extends for three months after your birthday month. If you sign up during the first three months, your coverage begins on the first day of your birthday month.
October 15 – December 7 every year. This is the most important window for the majority of Texans. During the AEP, you can:
Any changes you make during the AEP take effect on January 1 of the following year. Because plan networks, premiums, deductibles, and formularies change every single year, you should use the AEP to actively review your current plan and ensure it remains the best option for the upcoming year.
January 1 – March 31 every year. This period is exclusively for individuals who are already enrolled in a Medicare Advantage plan. If you started the year in a Medicare Advantage plan and quickly realized it is not working for you (e.g., your doctor left the network, or a new medication isn’t covered well), you have one opportunity to fix it. During the MA-OEP, you can:
You cannot use this period to switch from Original Medicare into a Medicare Advantage plan; you must already be in one to use this window.
Life events can sometimes trigger a Special Enrollment Period, allowing you to change your plan outside of the standard windows. Common triggers in Texas include:
With nearly 400 plans available statewide, picking the right one can feel overwhelming. Follow this exact progression to eliminate the noise and zero in on the plans that functionally serve your health profile.
Step 1: The Provider Audit Compile a list of every doctor, specialist, hospital system, and physical therapy clinic you actively use or plan to use in the near future. Check each of these providers against a prospective plan’s network directory. If your primary care doctor or critical specialist is out-of-network, eliminate that plan immediately if it is an HMO. If it is a PPO or HMO-POS, determine if you are comfortable paying the higher out-of-network rates to see them.
Step 2: The Formulary Test Gather all your current prescription pill bottles. Look up the plan’s formulary and confirm that every single drug is listed. Note which tier the drug is on, and calculate what the copay or coinsurance will be at the pharmacy counter. Furthermore, check if the plan imposes “Step Therapy” (requiring you to try a cheaper drug first) or “Quantity Limits” on your specific medications.
Step 3: Analyze the Core Medical Costs Look past the monthly premium. Look directly at the Maximum Out-of-Pocket (MOOP) limit and the inpatient hospital copayments. If you have a chronic condition that requires frequent specialist visits, a plan with a $15 specialist copay is vastly superior to a plan with a $50 specialist copay, even if the latter has slightly better dental benefits.
Step 4: Assess Your Geographic Lifestyle If you spend your entire year in your Texas hometown, a localized HMO with a tight network and rich extra benefits might be perfectly fine. However, if you spend summers in Colorado, or if you regularly travel out of state to visit grandchildren, an HMO will only cover you for strict medical emergencies while you are away. In that scenario, a PPO or a plan that explicitly offers nationwide travel benefits (often called visitor/travel programs) is a much safer choice.
Step 5: Compare the Extra Benefits Only after the doctors, the drugs, and the core medical costs are validated should you compare the bells and whistles. If two plans are identical in their medical and drug coverage, let the dental allowances and fitness memberships act as the tiebreaker.
Medicare Advantage is highly popular—in fact, over half of all eligible Medicare beneficiaries nationwide are now enrolled in a Part C plan. However, the system requires you to be an active participant in your healthcare logistics.
The biggest risk in Medicare Advantage is complacency. A plan that was perfect for you in 2024 might be terrible for you in 2025. Carriers can, and frequently do, drop hospitals from their networks, move medications to higher, more expensive tiers, or raise their MOOP limits. If you auto-renew blindly without reviewing your plan’s Annual Notice of Change (ANOC) document each fall, you may find yourself facing massive unexpected bills in January.
Additionally, the reliance on prior authorizations means that your doctor’s recommendation for care must be validated by the insurance company’s administrative staff. While most standard procedures are approved smoothly, the appeals process for a denied authorization can be frustrating and time-consuming.
Finally, recognize that moving from Original Medicare into Medicare Advantage is easy, but moving backward later in life can be difficult. If you leave Original Medicare (and your Medigap/Supplement plan) for a Medicare Advantage plan, and a few years later you develop a severe illness and want to return to Original Medicare to escape network restrictions, you may be subject to medical underwriting. In Texas, a Medigap carrier can deny you coverage or charge you exorbitant premiums based on your new health conditions if you try to buy a policy outside of your initial protected window.
Choosing the right Medicare Advantage plan is about managing risk, protecting your budget, and ensuring you have uninterrupted access to the clinicians you trust. Because the networks and pricing vary drastically down to the specific county you live in, the most effective next step is to run your specific doctors and drug list through the real-time data for your Texas zip code.
Prepare your list of medications, gather the names of your preferred hospitals and physicians, and identify what your realistic monthly budget for premiums and copays looks like.
