Medicare / Medicaid Essentials:
A Family Caregiver's Guide
As your aging loved one passes age 65, navigating Medicare becomes a crucial part of your caregiving journey. As you lean in to help, you'll realize quickly how overwhelming this system can be, even for someone who's navigated healthcare before Medicare--doing it independently for decades. It almost seems like some kind of cruel joke to have such complexity for aging people. The alphabet soup of Parts A, B, C, and D, the enrollment deadlines with permanent penalties, the gap coverage options—it's enough to confuse anyone, let alone someone in their seventies or eighties managing other health concerns. This overview will help you understand the basics and guide you as a caregiver providing support to your aging loved one, through important decisions, without becoming overwhelmed.

For people over 65, Medicare and Medicaid represent two distinct government healthcare programs with fundamental differences in eligibility, coverage, and payment structures—yet they can work together for those who qualify for both.
Medicare is primarily an age-based federal health insurance program that most Americans become eligible for at age 65, regardless of income or assets. We'll talk more about Medicare here shortly.
​
Medicaid, by contrast, is a needs-based program jointly funded by federal and state governments but administered at the state level, creating significant variation in eligibility and benefits across states. For seniors, Medicaid eligibility depends on having limited income and assets, with specific thresholds varying by state and sometimes by category of eligibility. While Medicare focuses primarily on acute medical care, Medicaid offers broader coverage that includes critical services Medicare doesn't cover—most notably long-term care in nursing homes, which represents Medicaid's single largest expenditure. For qualifying low-income seniors, Medicaid can also function as supplemental coverage to Medicare, covering Medicare premiums, deductibles, copayments, and providing additional benefits like dental, vision, and hearing--services that Original Medicare doesn't include. We'll provide a brief summary on Medicaid at the end of this guide.​
Medicare began as a straightforward single-payer health program for Americans 65+ (citizens and legal permanent residents with five consecutive years of U.S. residency, also certain disability situations qualify). This government-administered system, now called "Original Medicare," still exists today. However, private insurance companies gradually entered the Medicare landscape, culminating in the "Medicare Advantage" program (initially called Medicare+Choice) established by the Balanced Budget Act of 1997. Though Medicare Advantage has roots dating back to 1970s managed care experiments, it represents a fundamental shift from Medicare's original design—offering beneficiaries a choice between the traditional government-administered program or private insurance alternatives that receive government funding to provide Medicare benefits, sometimes with additional services but typically with network restrictions.
Medicare Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care (not long-term care), hospice, and some home health services. Most people pay no monthly premium if they or their spouse paid Medicare taxes while working.
​
Medicare Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services, and some home health care. Everyone pays a monthly premium (starting at $174.70 in 2024 for most people), which may be higher based on income.
​
Medicare Part C (Medicare Advantage) combines Parts A and B through private insurance companies that contract with Medicare. These plans often include prescription drug coverage and extra benefits like vision, dental, and hearing. They typically restrict care to network providers but may offer lower out-of-pocket costs.
​
Medicare Part D (Prescription Drug Coverage) helps cover medication costs through private insurance companies. Plans vary in cost and covered medications, making it essential to check if your parent's specific prescriptions are included.
Initial Enrollment Period: This seven-month window includes the three months before your parent's 65th birthday month, their birthday month, and the three months after. Missing this period can result in permanent premium penalties unless they qualify for a Special Enrollment Period.
​
Special Enrollment Period: If your parent is still working with employer coverage (or covered under your working spouse's plan), they may delay enrollment without penalty and sign up within 8 months of that coverage ending.
​
Open Enrollment Period: October 15-December 7 each year allows switching between Original Medicare and Medicare Advantage or changing drug plans.
Path 1: Original Medicare + Optional Supplemental Insurance
-
Parts A and B (Original Medicare)
-
Part D (separate drug plan)
-
Medigap policy (optional supplemental insurance that covers some out-of-pocket costs)
​
-
Pros: Freedom to use any doctor accepting Medicare nationwide; predictable costs with Medigap
​​
-
Cons: Multiple premiums; dental, vision, and hearing not covered
​
Path 2: Medicare Advantage (Part C)
-
All-in-one alternative to Original Medicare
-
Usually includes drug coverage and some additional benefits
​
-
Pros: Potentially lower monthly costs; extra benefits; out-of-pocket maximum
​​
-
Cons: Network restrictions; may need referrals and pre-authorizations; more likely denials and need to advocate for payment and coverage; benefits and costs can change annually; may not be able to get Medigap coverage if you want to switch back to Original Medicare.
​
Medicare Advantage plans have become increasingly popular, now covering nearly half of all Medicare beneficiaries, but they remain the subject of significant controversy among healthcare policy experts, patient advocates, and medical providers.
Proponents highlight that these private insurance alternatives to Original Medicare often provide additional benefits not covered by traditional Medicare—such as dental, vision, hearing, fitness memberships, and transportation services—while capping annual out-of-pocket costs. Many plans charge low or even zero monthly premiums beyond the standard Part B premium, making them financially attractive to budget-conscious seniors. Supporters also point to Medicare Advantage's integrated care model, which can better coordinate services for beneficiaries with complex needs, and value-based care incentives that potentially improve quality while controlling costs.
Critics, however, raise substantial concerns about Medicare Advantage's impact on both beneficiaries and the Medicare system as a whole. A central criticism involves network restrictions that limit beneficiary choice to specific doctors and hospitals, potentially disrupting established care relationships or creating access barriers, especially in rural areas or for those seeking specialized care. Prior authorization requirements—where insurers must approve services before they're covered—have drawn particular fire, with physicians reporting that these administrative hurdles often delay necessary care and create burdensome paperwork. Recent government investigations have identified troubling patterns of inappropriate care denials, with some plans initially rejecting services that met Medicare coverage rules, forcing vulnerable patients to navigate complex appeals processes. Remember, these are for-profit companies, so there is a potential conflict--denying benefits improves their profits.
Another common concern is that once you go with Medicare Advantage, it may be technically possible to roll back to Original Medicare, but practically difficult. What’s more, you may no longer be able to get some of the supplemental, “Medigap” policies. Since Medicare Advantage plans are “sold” by commissioned sales people, it’s easy for a senior to get “sold” into a Medicare Advantage plan without truly understanding the plan or it’s implications. And some of the telemarketing and ad campaigns come off as truly predatory.
Perhaps the most significant systemic controversy surrounds Medicare Advantage's payment structure and its fiscal impact on the Medicare program. Multiple studies by government watchdogs have found evidence of "upcoding"—where plans make beneficiaries appear sicker on paper than their Original Medicare counterparts through aggressive diagnosis documentation, resulting in higher payments from the government. This practice has contributed to Medicare Advantage plans receiving payments estimated at 106-115% of what the same beneficiaries would cost in Original Medicare, despite initially being promoted as a cost-saving alternative. Critics argue these excess payments—potentially hundreds of billions of dollars over time—threaten Medicare's long-term financial sustainability while generating substantial profits for insurance companies.
The debate continues to evolve as policymakers consider reforms to address these concerns while preserving the additional benefits and coordinated care that many beneficiaries value in their Medicare Advantage plans.
But it at least raises the truth in advertising question, "Is Medicare Advantage really an advantage? Maybe not for many aging people.
Finding truly unbiased advice about choosing between Original Medicare and Medicare Advantage presents a significant challenge for families navigating healthcare decisions for aging loved ones. The Medicare landscape is shaped by powerful financial incentives that influence information sources in subtle and not-so-subtle ways. Insurance brokers and agents, while knowledgeable about plan details, typically earn substantially higher commissions for Medicare Advantage enrollments compared to Medigap policies that supplement Original Medicare—sometimes 7-8 times more for the initial enrollment. This commission structure naturally creates incentives to steer beneficiaries toward Medicare Advantage plans, even when Original Medicare might better suit their needs. The financial influence extends beyond individual agents to the massive marketing budgets of insurance companies, which flood the airwaves with Medicare Advantage advertisements during enrollment periods while Medigap options receive comparatively little promotion.
​
Even seemingly objective online comparison tools and educational resources often have hidden financial relationships with insurers. Many popular Medicare information websites generate revenue through lead generation for insurance companies, creating subtle biases in how they present information or structure plan comparisons. Government resources like Medicare.gov provide factual information but typically avoid making direct comparisons or recommendations between the two paths. Meanwhile, healthcare providers themselves may have strong opinions based on their experiences with reimbursement rates and administrative requirements, potentially coloring their advice based on business considerations rather than purely patient welfare.
​
The complexity of Medicare itself compounds the problem of finding unbiased guidance. With countless plan variations, regional differences, and individual health considerations, truly objective advice requires a comprehensive understanding of a beneficiary's specific situation—their doctors, medications, health conditions, financial resources, risk tolerance, and geographic location. Few advisors have both the expertise and the incentive structure to provide this level of personalized, unbiased analysis.
​
State Health Insurance Assistance Programs (SHIPs) offer free, government-funded counseling without financial incentives to recommend specific plans, but these programs often have limited resources and appointment availability. Sometimes local Senior Centers or our local Area Agency on Aging will offer advisory sessions or appointment with the information and resources from the state SHIP programs. But they can’t sell you either Medicare Advantage plans, or Medigap plans. So eventually you are going to need to end up in the sphere of the Medicare sales system.
​
At the end of the day, you’ll want to document your research from multiple sources, noting potential biases and comparing recommendations to identify patterns that might reveal underlying incentives—ultimately helping your aging loved ones make more informed decisions based on their unique healthcare needs rather than an advisor's financial interests.

Medicaid
For many families supporting an aging loved one, Medicaid becomes a crucial piece of the long-term care puzzle, especially when facing the prospect of nursing home costs that Medicare doesn't cover. Unlike Medicare's age-based eligibility, Medicaid is a needs-based program that provides comprehensive health coverage for those with limited income and assets. For seniors over 65, Medicaid can be a financial lifeline, covering services that Medicare doesn't—most importantly, long-term nursing home care, which can otherwise cost $7,000-$12,000 monthly in most states. Medicaid can also work alongside Medicare for those who qualify for both programs (called "dual eligibles"), covering Medicare premiums and cost-sharing while adding benefits like dental, vision, hearing, and personal care services that support aging in place.
Approximately 12.5 million Americans—known as "dual eligibles"—qualify for both Medicare and Medicaid. For these individuals, Medicare serves as the primary payer for covered services, with Medicaid covering remaining costs and providing additional benefits. This dual coverage can be particularly valuable for seniors requiring nursing home care, as Medicare's coverage is limited to short-term skilled nursing facility stays following hospitalization, while Medicaid can cover long-term care indefinitely once a senior has spent down their assets to qualify. Understanding the distinct roles of these programs is essential for families planning for an aging parent's care needs, particularly when considering potential future long-term care requirements and the financial implications of spending down assets to qualify for Medicaid while maintaining Medicare coverage for primary healthcare needs.
Qualifying for Medicaid as a senior requires meeting both income and asset limits, which vary by state and by program type. Most states limit monthly income to around $2,000-$3,000 for individuals (though some states use higher limits), with asset restrictions typically capping "countable resources" at $2,000-$3,000 for individuals and $3,000-$6,000 for couples. However, not all assets count toward this limit—your loved one's home (up to certain equity limits), one vehicle, personal belongings, household items, certain burial funds, and some life insurance policies are generally exempt. For married couples where only one spouse needs nursing home care, special "spousal impoverishment" protections allow the healthy spouse living at home to keep significantly more income and assets, including half of the couple's joint assets up to approximately $148,000 (in 2023) plus their own monthly income allowance.
It's important to understand that Medicaid has a "look-back period"—typically five years—during which any gifts or transfers of assets for less than fair market value may trigger penalties that delay eligibility. This means planning ahead is essential if Medicaid might be needed in the future. Many families work with elder law attorneys to develop appropriate strategies for qualifying while protecting as many assets as legally possible. Some states also offer "Medicaid waiver" programs that provide home and community-based services for those who qualify financially for nursing home care but wish to remain at home—though these programs often have limited slots and waiting lists. The application process itself can be complex, requiring extensive documentation of income, assets, and medical need, but local Area Agencies on Aging, Medicaid offices, and elder law attorneys can provide guidance through this process. With proper planning and understanding of your state's specific rules, Medicaid can become an invaluable resource for ensuring your loved one receives necessary care without depleting family resources.
