Medicare typically covers around half of retirees' healthcare expenses, yet medical costs remain the second-largest expense in retirement, just behind housing. A 2025 study by Fidelity Investments estimates that a healthy 65-year-old couple will need approximately $345,000 to manage healthcare costs throughout their retirement (excluding any long-term care needs).

Clients may seek your guidance during the Medicare enrollment process, as there are many factors to consider when making their election choices. To avoid lifelong financial penalties, it’s important that individuals enroll within the proper timeframes, which depend on age, Social Security status, and existing coverage.

If any of your clients are looking to adjust their Medicare selections, now is the perfect time. Medicare open enrollment takes place from October 15 to December 7 each year. This is an opportunity for individuals to switch their Medicare elections, whether they are interested in changing their Original Medicare selection (Parts A and B) to include Part D, switching to Medicare Advantage (Part C), or vice versa for the next calendar year.

Let’s walk through the fundamentals of Medicare, as discussed in a webinar led by our Product Marketing Manager, Alexus:

Which expenses does Medicare cover?

A breakdown of the different parts of Medicare

Medicare is divided into four distinct "parts,” which we review below.

Medicare Part A - Hospital Insurance

Medicare Part A generally comes with no out-of-pocket premium, but it does require both a deductible and coinsurance. It primarily covers hospital care, provided the patient is admitted under a doctor’s official order. A stay of 1-60 days must meet the $1,676 deductible. Days 61 to 90 have no additional deductible, but there’s a $419 per day coinsurance. Days 91-150 come with an $838 per day coinsurance for lifetime reserve days. After day 150, no costs are covered by Medicare. This means that a 90-day stay could cost your client $14,246.

Medicare Part A also covers a skilled nursing facility stay for a limited time and under certain conditions after hospitalization. Days 1-20 cost $0, with days 21-100 incurring a cost of $209.50 a day. Anything beyond 101 days, even for care under the right conditions, will not be covered.

Certain home health care services can be covered completely by Medicare Part A, with a coinsurance of 20% of the Medicare-approved amount for durable medical equipment. It is important to note that it covers home health care services, and not homemaker services, which involve daily activities such as cooking, shopping, and cleaning, unrelated to the care plan.

Nursing home care is not covered under Medicare Part A, but skilled medically necessary nursing care administered in a nursing home can be covered.

Medicare Part A covers hospice care, or end-of-life care for terminally ill patients. Once activating hospice care, Medicare Part A will not cover any treatments toward curing the terminal illness nor any room and board unless the hospice team determines a need for short-term inpatient or respite care. Any outpatient prescription drugs can incur up to a $5 copay and any inpatient respite care can incur a coinsurance of 5% for the Medicare-approved amount.

Medicare Part B - Medical Insurance

Medicare Part B provides coverage for non-hospital medical services, excluding vision and dental unless the beneficiary has opted in. This includes expenses related to items such as ambulance services, durable medical equipment (DME), and oxygen equipment. Beneficiaries face an annual deductible of $257 and a 20% coinsurance on general costs for medical services (as long as the doctor “accepts assignment” or the Medicare-approved amount for that service), inpatient, and outpatient care. Income related monthly adjustments (IRMAA) apply to Part B premiums. These income related monthly adjustments look at a client’s taxable income from two years prior. Premiums range from $185 to $628.90, depending on income.

Medicare Part C - Medicare Advantage

Medicare Advantage includes all the benefits of Part A and Part B but is administered by private companies that contract with Medicare. Optional add-ons such as vision, dental, and hearing coverage are available, making Medicare Advantage a potential all-in-one solution for some clients. Premiums vary by plan and are higher than just the Part B premiums.

Medicare Part D - Prescription Drug Coverage

Medicare Part D coverage varies depending upon the plan selected, but the deductible cannot be higher than $590, after meeting the deductible and out-of-pocket spending reaches $2,000, then catastrophic coverage starts. At that point, covered Part D drugs come at no extra cost. Income related monthly adjustment amount (IRMAA) also impacts Medicare Part D. IRMAA increases range from $13.70 to $85.80 plus the unique plan’s premium.

Medicare and Inflation Reduction Act of 2022 Changes

The Inflation Reduction Act of 2022 has significantly shaped the landscape of healthcare planning. One key benefit is the $35 monthly cap on insulin, which helps limit price surges for this vital medication. Additionally, starting in 2025, drugmakers are required to provide rebates to Medicare if there are sudden spikes in drug prices that are higher than inflation, allowing retirees to have more predictable medical expenses. Other changes included capping out-of-pocket expenses for beneficiaries (effective 2025), and allowing the government to negotiate prescription drug prices, further controlling costs (majority slated to start 2026).

Medigap supplemental plans

Beneficiaries of Original Medicare have the option to sign up for Medigap plans, a supplemental insurance provided by private companies. Medigap can be combined with Parts A, B, and D to fill gaps in Medicare coverage. However, it cannot be used alongside Medicare Part C (Medicare Advantage), as both are private insurance plans, and their coverage would overlap.

What influences Medicare decisions?

How to choose Medicare options based on current health and lifestyle

Health and lifestyle

The chart above highlights health and lifestyle scenarios that may apply to your clients. For instance, retirees who travel frequently might prefer Original Medicare, as it provides flexibility to visit doctors wherever they are, without being restricted to a specific network, unlike Medicare Advantage. This may be less of a concern for those planning to stay local.

Clients who require more frequent doctor visits or have more complex health needs might consider adding Medigap to their Original Medicare coverage. While it comes with higher premiums, it provides more predictable out-of-pocket costs, helping to manage ongoing medical expenses.

Retirement income

Medicare Part B and D premiums are determined by your retirement income. With RightCapital, you can develop a retirement drawdown strategy that provides your clients with more tax-efficient distributions or look at performing Roth conversions during lower tax bracket years to optimize tax-free ending wealth. Our platform helps assess the impact of these tax-smart strategies on Medicare Part B and D premiums, particularly when aiming to avoid Income-Related Monthly Adjustment Amounts (IRMAA), which can be triggered by actions that raise taxable income such as Roth conversions. Taking it a step further, RightCapital can run a dynamic calculation of performing Roth conversions without triggering IRMAA, or to certain premium brackets.

When should clients enroll in Medicare?

Medicare enrollment period chart

Enrolling at the wrong time can lead to higher premiums. The initial enrollment period begins three months before a client turns 65 and lasts a total of seven months. If your client is already collecting Social Security by their 65th birthday, they'll automatically be enrolled in Medicare Parts A & B. With the RightIntel business intelligence dashboard (included in Premium and Platinum subscriptions), you can choose to receive notifications when clients are approaching 65, enabling you to proactively assist them with Medicare enrollment.

If the client or their spouse is still working at age 65 and covered by a comprehensive employer-sponsored health plan, they may be able to delay enrollment in Part B and Part D. The special enrollment period to re-enroll in Part B extends for eight months after the employer policy ends, while the special enrollment window for Part D (with creditable coverage) is 63 days after the end of the policy.

How can RightCapital help with Medicare decisions?

RightCapital streamlines the Medicare planning process for both advisors and their clients through a dedicated Medicare module. This space allows you to easily review key factors such as a client's traveling habits, health status, and premium risk tolerance, ensuring that Medicare filing decisions align with their unique needs.

In addition to assessing these important considerations, the module guides you through any factors that might lead to a non-standard enrollment period, with a helpful breakdown of the client's specific timeline. To further simplify the Medicare filing process, we've included a "Tips" tab that highlights important points to watch out for, such as no longer being able to contribute to an HSA once taking Medicare. Additional resources can be easily found within this tool such as direct links to the Social Security Administration and Medicare websites for easy access to information.

Our goal is to make Medicare decisions easier and more manageable for your clients, demystifying what can often seem like a complex process.

RightCapital offers additional features to account for Medicare planning. Here's Alexus once again, explaining how to navigate and address the specific nuances that may arise in various client scenarios:


Navigating Medicare decisions can be challenging and overwhelming, especially as clients face significant life transitions such as moving from the workforce into retirement. At this stage, securing the right healthcare coverage becomes a top priority. Post-Medicare filing is an important phase of a client’s life, so it is important to be able to capture the nuances of Medicare Part B and D premiums that can account for the impacts of your proposed plans.

RightCapital simplifies this process by helping advisors address questions about Medicare plans, guiding clients through their enrollment periods, and offering peace of mind when they need it most.
