Comparing Medicare plans in Maryland
Medicare Part C, universally known as Medicare Advantage, is a bundled alternative to Original Medicare. When you enroll in a Part C plan in Maryland, a private health insurance carrier—rather than the federal government—becomes responsible for managing and paying your medical claims. By law, these carrier-insured policies must cover all services that traditional Medicare Part A (hospital) and Part B (medical) provide. However, they structure the costs differently, require you to use established local provider networks, and typically bundle additional benefits like prescription drug coverage (Part D), routine dental care, and vision services into a single policy.
If you are approaching Medicare eligibility or re-evaluating your current coverage, understanding how Part C functions is critical. This guide serves as a comprehensive overview of carrier-insured Medicare in Maryland. It covers how the mechanics of these plans work, what they actually cost, the specific types of plans available (such as HMOs and PPOs), and how to systematically evaluate which plan best fits your medical needs and financial realities.
To understand Part C, you must first understand the baseline it replaces. When you turn 65 and enroll in Original Medicare, your primary insurance comes directly from the federal government. You can go to any doctor or hospital in the United States that accepts Medicare. The government pays 80% of your approved Part B outpatient bills, and you are generally responsible for the remaining 20%—with no upper limit on what that 20% could cost you in a catastrophic health year.
Medicare Part C completely changes this structure.
When you enroll in a Part C plan through a private carrier like Aetna Medicare, CareFirst BlueCross BlueShield, or UnitedHealthcare, you are technically still in the Medicare program, but you have opted to receive your benefits through the carrier. The federal government (specifically, the Centers for Medicare & Medicaid Services, or CMS) pays that private carrier a fixed monthly amount to take on the financial risk of your healthcare.
In exchange for managing your care, the carrier is allowed to dictate the terms of how you receive it, provided they meet strict federal minimums. This means the carrier establishes a network of contracted doctors, sets its own copayments for various services, and determines the rules for seeing specialists.
Because the carrier is receiving a monthly payment from the government to manage your health, and because they actively negotiate lower rates with their specific network of providers, they can often afford to offer these plans at a $0 monthly premium to the consumer, while also throwing in extra benefits that federal Medicare does not cover.
The most common misconception about Medicare Part C is that it provides “less” medical coverage than Original Medicare. Legally, this cannot be true. Federal regulations mandate that every Medicare Advantage plan must cover every service deemed medically necessary under Part A and Part B.
If Original Medicare covers a specific knee replacement surgery, your Part C plan must also cover that exact surgery. If Original Medicare covers a specific diagnostic MRI, your Part C plan must cover it.
Where the carrier exercises control is in how you access that care and what you pay at the point of service.
Under Part C, the carrier may require:
The primary reason most beneficiaries choose a Part C plan over Original Medicare is the inclusion of supplemental benefits. The federal Medicare program has rigid limitations: it explicitly does not cover routine dental work, eyeglasses, hearing aids, or gym memberships.
Carriers use supplemental benefits to compete for your enrollment. Among the 60 plans available in Maryland, benefits vary substantially from one plan to the next, but commonly include:
Most Part C plans are designated as “MA-PD” (Medicare Advantage Prescription Drug) plans, meaning Part D drug coverage is fully integrated. You do not need to buy a separate standalone drug plan. You simply present one ID card at the pharmacy and the doctor’s office. Your medications are categorized into “tiers” (Tier 1 for preferred generics, Tier 2 for standard generics, up to Tier 5 for specialty drugs), with different copays for each tier.
Part C plans routinely include allowances for ancillary care. A plan might offer a $1,500 annual allowance for comprehensive dental work (crowns, root canals, dentures), a $200 annual credit toward prescription eyewear, and fixed copays for hearing exams and premium hearing aids.
Many plans now issue members a prepaid debit card reloaded quarterly (e.g., $50 every three months) to purchase eligible over-the-counter items at local pharmacies. This can be used for vitamins, pain relievers, bandages, toothpaste, and sometimes even healthy groceries, depending on the specific plan’s rules.
Programs like SilverSneakers or Renew Active are standard inclusions in the majority of Part C plans, granting you free access to thousands of participating gyms and fitness centers across Maryland and the country.
Certain plans, such as the Aetna Medicare Eagle Giveback (PPO), offer a “Part B reduction.” Since you are still required to pay your standard Medicare Part B premium to the government while on a Part C plan, a giveback plan uses some of its government funding to pay a portion of that premium for you. If a plan has a $50 giveback, your monthly Social Security check will increase by $50 because less money is being deducted to cover your Part B premium.
Evaluating a Part C plan requires looking past the monthly premium. Even if a plan costs $0 per month, it is not free health insurance. You will pay for your care as you use it.
Instead of paying a flat 20% of the bill as you would under Original Medicare, Part C plans generally rely on fixed, predictable copayments.
Some highly specialized services, such as chemotherapy drugs administered in an outpatient setting, may still require coinsurance (a percentage of the cost, usually up to 20%), mirroring Original Medicare.
The single most important financial feature of a Medicare Part C plan is its Maximum Out-of-Pocket (MOOP) limit.
Because Original Medicare has no cap on your potential expenses, a severe illness (like cancer or a major heart attack) can result in tens of thousands of dollars in medical bills representing your 20% share.
By federal law, every Part C plan must set a MOOP. In Maryland, these limits vary by plan but typically range from roughly $3,500 to the federal maximum allowed limit of around $8,850. The MOOP is an absolute ceiling. Once your accumulated copayments and coinsurance for covered medical services reach that dollar amount in a calendar year, the plan pays 100% of your covered medical costs for the remainder of the year. (Note: Prescription drug costs and supplemental dental/vision costs do not count toward your medical MOOP).

When you shop the 60 available Part C plans in Maryland, you will primarily encounter three specific network structures. Understanding the difference is vital to ensuring you can keep your doctors.
The HMO is the most common and tightly managed type of Part C plan. Plans like the Alterwood Advantage Choice (HMO) and Alterwood Advantage Select (HMO) require you to receive all routine and specialized care from doctors and facilities within the carrier’s contracted network.
If you go to a doctor outside the HMO network for routine care, the plan will pay absolutely nothing, and you will be responsible for 100% of the bill. The only exception is for life-threatening medical emergencies or urgent care, which are covered anywhere in the country. HMOs also typically require you to declare a Primary Care Physician (PCP) who coordinates your care and issues referrals before you can see specialists. Because the network is heavily restricted, HMO plans often boast the lowest premiums, the lowest copays, and the richest extra benefits.
PPO plans, such as the Aetna Medicare Elite (PPO), offer more flexibility. These plans have an established network of preferred providers, but they also grant you the freedom to go “out of network” to see any doctor who accepts Medicare and agrees to bill the plan.
The tradeoff for this flexibility is cost. If you stay in-network, you pay a lower copay (e.g., $35 for a specialist). If you go out of network, you pay a higher cost-sharing amount (e.g., a $65 copay, or a 40% coinsurance). PPOs do not require you to select a PCP, nor do they require referrals to see specialists. They are ideal for individuals who split their time between Maryland and another state, or for those who simply refuse to be locked out of seeing specific non-network providers.
A Special Needs Plan is a highly targeted type of Part C plan restricted to individuals who meet specific criteria. In Maryland, the most prevalent type is the Dual-Eligible Special Needs Plan (D-SNP), such as the Alterwood Advantage Dual Secure (HMO D-SNP) or the Alterwood Advantage Dual Value (HMO D-SNP).
D-SNPs are engineered exclusively for beneficiaries who qualify for both federal Medicare and Maryland Medicaid based on low income. These plans coordinate benefits between the two programs seamlessly, often resulting in $0 monthly premiums, $0 medical copays, massive allowances for over-the-counter items, and specialized care coordination services to manage chronic illnesses. If you have both Medicare and Medicaid, a D-SNP is almost always the most advantageous way to receive your benefits.
Health insurance is inherently local, and the carriers operating in Maryland have built specific networks spanning the state’s diverse geography—from the Baltimore metro area out to the Eastern Shore and western counties. The active Medicare Part C carriers in Maryland include:
When choosing a carrier, the brand name is secondary to one critical factor: Are your specific doctors in their network? A plan from Kaiser Permanente operates entirely differently than a PPO from UnitedHealthcare. Always verify network status before enrolling.
You are eligible to enroll in a Medicare Part C plan if you meet all of the following baseline criteria:
You cannot enroll in, drop, or switch a Part C plan whenever you want. Medicare enforces strict enrollment windows to prevent individuals from waiting until they are severely ill to purchase coverage.
Your first opportunity to choose a Part C plan happens when you first become eligible for Medicare. Your IEP is a 7-month window that includes the three months before your 65th birthday month, the month of your birthday, and the three months after. If you enroll during this time, your coverage begins seamlessly.
The most critical time of the year for Medicare beneficiaries is the AEP, which runs strictly from October 15 through December 7 every single year. During this window, you can:
If you are already enrolled in a Part C plan on January 1, you are granted a secondary window from January 1 through March 31. During the MA-OEP, you are allowed to make one change: you can switch to a different Part C plan, or you can drop your Part C plan and return to Original Medicare. You cannot use this period to move from Original Medicare into a Part C plan. This serves as a “buyer’s remorse” window if you realize the plan you chose during AEP does not cover your needs or your doctors.
Certain qualifying life events grant you a Special Enrollment Period, allowing you to change plans outside the standard windows. Common SEPs include:
Selecting the right Part C plan from the 60 available options in Maryland requires a clinical, methodical approach. Do not choose a plan based entirely on the brand name, the premium, or a television commercial. Follow this exact decision-mapping process:
1. Check Your Doctors First A $0 premium plan is useless if your primary care physician or key specialists are not in the network. Compile a list of your doctors and verify their participation status with the specific HMO or PPO plan you are evaluating. Do not just ask the doctor “Do you take Medicare?”—you must ask “Are you in-network for the specific [Carrier Name] [Plan Name] HMO/PPO?”
2. Check Your Prescription Drugs (The Formulary) Gather all your current prescription bottles. Every Part C plan has a unique “formulary” (a list of covered drugs). A medication that is a cheap Tier 1 generic on an Alterwood Advantage plan might be a more expensive Tier 3 brand-name drug on a CareFirst plan, or it might not be covered at all. Ensure all your daily medications are listed on the plan’s formulary, and check what tier they fall into to estimate your monthly pharmacy costs.
3. Evaluate the MOOP Look at the Maximum Out-of-Pocket limit. If you have a catastrophic medical year—requiring multiple hospitalizations, surgeries, and daily therapies—the MOOP is the maximum amount you will have to pay. Are you comfortable with a $4,500 MOOP? What about an $8,000 MOOP? Ensure you have the savings to cover this ceiling if the worst occurs.
4. Assess Your Lifestyle and Ancillary Needs Do you split your time between Maryland and Florida? An HMO will not work for you; you need a PPO with a broad national network. Do you desperately need $2,000 worth of dental crowns this year? Look closely at the dental allowance differences between plans. Do you have a low, fixed income and qualify for state aid? You must look at D-SNP options first, as they are explicitly designed to protect your assets.
5. Understand the Tradeoffs Part C requires you to play by the carrier’s rules. You are trading the absolute freedom of Original Medicare (where you can see anyone without referrals) for lower predictable costs, capped risk, and bundled extras. If you are comfortable staying within a structured network and navigating prior authorizations for major procedures, Part C is an exceptional vehicle for managing healthcare costs. If you prioritize absolute freedom and lack of administrative friction above all else, you may want to investigate Original Medicare paired with a Medigap supplement instead.
