Medicare for Caregivers: What You Need to Know When Helping a Loved One

Caring for a parent, spouse, or other loved one is one of the most meaningful things you can do — and one of the most demanding. If the person you are helping is on Medicare or approaching Medicare eligibility, you may find yourself navigating a health insurance system that feels overwhelming at first glance. From enrollment deadlines to prescription drug coverage to claims appeals, there is a lot to keep track of. The good news is that you do not have to figure it all out alone. This guide walks you through the essentials of Medicare from a caregiver's perspective, so you can make informed decisions and advocate effectively for the person in your care.

Understanding Medicare Basics as a Caregiver

Before you can help your loved one make coverage decisions, it helps to have a working understanding of how Medicare is structured. Medicare is divided into several parts, each covering different types of services:

• Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. Most people pay no monthly premium for Part A if they or their spouse paid Medicare taxes for at least 40 quarters. The Part A deductible for 2026 is $1,736 per benefit period.
• Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services, durable medical equipment, and more. The standard Part B premium for 2026 is $203.90 per month, with an annual deductible of $257.
• Part C (Medicare Advantage) is an alternative way to receive Medicare benefits through private insurance plans approved by Medicare. These plans include all Part A and Part B coverage and often bundle Part D prescription drug coverage along with additional benefits such as dental, vision, and hearing.
• Part D (Prescription Drug Coverage) helps cover the cost of prescription medications. Part D is available as a standalone plan with Original Medicare or as part of a Medicare Advantage plan. In 2026, the Part D out-of-pocket cap is $2,100, and the maximum deductible is $615.

For a more detailed breakdown of each part, see our guide to Medicare Parts A, B, C, and D.

Becoming an Authorized Representative

One of the first practical steps as a caregiver is making sure you have the legal authority to act on your loved one's behalf when dealing with Medicare, Social Security, and healthcare providers. Depending on the situation, several types of authorization may be relevant.

• Power of Attorney (POA): A durable power of attorney for healthcare or finances — established through your state's legal process — allows you to make decisions on behalf of your loved one if they become unable to do so themselves. A POA is broadly recognized by insurance companies, providers, and government agencies, though each entity may have its own requirements for accepting it.
• CMS-1696 Appointment of Representative Form: If you need to file Medicare claims or appeals on behalf of a beneficiary, you may need to submit Form CMS-1696. This form specifically authorizes you to act as a representative in Medicare claims matters. Both you and the beneficiary (or someone authorized to sign for them) must sign the form.
• Social Security Representative Payee: If your loved one is unable to manage their own finances, you can apply to become a representative payee through the Social Security Administration. This gives you authority to manage their Social Security and Medicare premium payments. The application process requires an in-person visit to a Social Security office.

Which type of authorization you need depends on what tasks you are performing. Talking to a doctor about treatment options may require a healthcare POA, while filing an appeal with Medicare generally requires a CMS-1696 form. If you are unsure where to start, a local SHIP (State Health Insurance Assistance Program) counselor can help you understand the requirements at no cost.

Helping with Enrollment Decisions

Medicare enrollment can be confusing even for the beneficiary themselves, so having a caregiver who understands the key enrollment windows is invaluable. Here are the periods you should know:

• Initial Enrollment Period (IEP): This is a seven-month window surrounding a person's 65th birthday (three months before, the birthday month, and three months after). This is generally the first opportunity to sign up for Part A and Part B.
• Annual Enrollment Period (AEP): Running from October 15 through December 7 each year, the AEP is when beneficiaries can switch between Original Medicare and Medicare Advantage, change Medicare Advantage plans, or join, switch, or drop Part D coverage. Changes take effect on January 1.
• Open Enrollment Period (OEP): From January 1 through March 31, people already enrolled in a Medicare Advantage plan can switch to a different Medicare Advantage plan or return to Original Medicare and add a standalone Part D plan. This period is not available to people on Original Medicare looking to join a Medicare Advantage plan.
• Special Enrollment Periods (SEPs): Certain life events — such as moving to a new service area, losing employer coverage, or qualifying for Medicaid — may trigger a Special Enrollment Period that allows changes outside the standard windows. For more details, see our guide to Medicare Special Enrollment Periods.

When helping your loved one during enrollment, consider creating a checklist that includes their current medications, preferred doctors, anticipated medical needs for the coming year, and monthly budget for premiums. The Medicare Plan Finder at Medicare.gov allows you to compare plans side by side based on costs, coverage, and pharmacy networks. You can enter your loved one's medications to see how each plan covers them and what the estimated annual costs would be.

Managing Medications and Part D

Prescription drug management is often one of the most hands-on responsibilities for caregivers. Staying organized can help you avoid gaps in coverage and unnecessary costs.

• Keep an updated medication list. Include the drug name, dosage, prescribing doctor, and pharmacy. Bring this list to every doctor's appointment and use it when comparing Part D plans during enrollment.
• Check the plan's formulary. Every Part D plan maintains a formulary — a list of covered drugs organized into cost tiers. Before enrolling in or renewing a plan, verify that all of your loved one's medications are on the formulary and note which tier they fall under, as this affects copay amounts.
• Understand the out-of-pocket cap. Starting in 2025 and continuing in 2026, Part D includes a $2,100 annual cap on out-of-pocket prescription drug spending. Once your loved one reaches this threshold, they pay nothing for covered drugs for the rest of the year.
• Use the Medicare Prescription Payment Plan. If your loved one has high drug costs early in the year, the Medicare Prescription Payment Plan allows them to spread their out-of-pocket Part D costs into predictable monthly installments rather than paying large amounts at the pharmacy counter. You can opt into this program through the Part D plan.
• Insulin costs are capped. If your loved one uses insulin, the cost is capped at $35 per month per covered insulin product under Part D.

Reviewing Part D coverage annually — ideally during the AEP — is one of the most impactful things you can do, since formularies, premiums, and pharmacy networks may change from year to year.

Coordinating Medicare with Other Coverage

Many Medicare beneficiaries have additional health coverage, and understanding how these programs interact with Medicare is important for avoiding billing issues and ensuring your loved one receives full benefits.

• Employer coverage: If your loved one (or their spouse) is still working and has group health insurance through an employer with 20 or more employees, the employer plan generally pays first and Medicare pays second. If the employer has fewer than 20 employees, Medicare typically pays first. For a detailed look at how this works, see our guide to Medicare and employer coverage coordination of benefits.
• VA benefits: Veterans may be eligible for healthcare through the Department of Veterans Affairs in addition to Medicare. The two programs operate independently — VA benefits do not count as Medicare coverage and vice versa. However, having both can give your loved one more flexibility in choosing where to receive care. Our guide to Medicare for veterans explains how these benefits work together.
• Medicaid: If your loved one qualifies for both Medicare and Medicaid (known as being dual-eligible), Medicaid may help cover Medicare premiums, deductibles, and copayments. Dual-eligible beneficiaries are also automatically enrolled in Extra Help for Part D.
• TRICARE for Life: Military retirees with TRICARE for Life must enroll in both Part A and Part B. TRICARE for Life then acts as a supplement, generally covering costs that Medicare does not pay, such as copayments and deductibles.

When multiple coverage sources are involved, it is important to understand which plan pays first (the primary payer) and which pays second. Billing errors related to coordination of benefits are common, so keeping clear records of all coverage your loved one has can help resolve issues quickly.

Appealing Denied Claims

If a Medicare claim is denied — whether for a medical service, procedure, or prescription — your loved one has the right to appeal. As a caregiver, you can file the appeal on their behalf, provided you have the appropriate authorization (typically through a completed CMS-1696 form or a valid power of attorney).

The Medicare appeals process has five levels:

• Level 1 — Redetermination: An internal review by the entity that issued the denial. You generally have 120 days from the date of the denial notice to file.
• Level 2 — Reconsideration: An independent review by a Qualified Independent Contractor (QIC). You have 180 days from the Level 1 decision to request this.
• Level 3 — Administrative Law Judge Hearing: A more formal hearing, available if the disputed amount meets a minimum dollar threshold.
• Level 4 — Medicare Appeals Council Review: A review by the Department of Health and Human Services.
• Level 5 — Federal District Court: A judicial proceeding, typically reserved for cases involving significant amounts.

Many denials result from billing errors or missing documentation rather than a genuine coverage exclusion. When filing an appeal, include a clear written explanation of why you disagree with the decision, along with supporting documents such as a letter of medical necessity from the treating physician. For a step-by-step walkthrough, see our guide to appealing a Medicare decision.

Financial Assistance Programs

If your loved one is struggling with Medicare costs, several programs may help reduce premiums, deductibles, and out-of-pocket expenses.

• Extra Help (Low-Income Subsidy): This federal program helps Medicare beneficiaries with limited income and resources pay for Part D prescription drug costs, including premiums, deductibles, and copayments. You can apply through the Social Security Administration or at Medicare.gov. For full details, see our guide to Extra Help with Medicare Part D.
• Medicare Savings Programs (MSPs): These state-administered programs help pay Medicare Part B premiums and, in some cases, Part A premiums, deductibles, and coinsurance. The four levels are Qualified Medicare Beneficiary (QMB), Specified Low-Income Medicare Beneficiary (SLMB), Qualifying Individual (QI), and Qualified Disabled and Working Individuals (QDWI). Each has different income and resource limits. For a breakdown of each program, see our guide to Medicare Savings Programs.
• SHIP counseling: The State Health Insurance Assistance Program provides free, unbiased counseling to Medicare beneficiaries and their caregivers. SHIP counselors can help with plan comparisons, enrollment, billing problems, appeals, and applications for financial assistance programs. You can find your local SHIP office by visiting Medicare.gov or calling 1-800-MEDICARE (1-800-633-4227).
• Benefits checkup tools: Online resources such as the National Council on Aging's BenefitsCheckUp tool can help you identify federal, state, and local programs your loved one may qualify for based on their income, location, and circumstances.

Applying for these programs on behalf of your loved one may require documentation of their income and assets, so it helps to have recent tax returns, bank statements, and benefit award letters on hand.

Caregiver Self-Care and Resources

Navigating Medicare for someone else takes time and energy on top of the physical and emotional demands of caregiving. Taking care of yourself is not a luxury — it is essential for being able to continue providing support over the long term.

Here are some resources that may help:

• Respite care: Medicare may cover short-term respite care under certain conditions, particularly for beneficiaries receiving hospice care. Respite care provides temporary relief for the primary caregiver by placing the beneficiary in an approved facility for a short stay. Check with the hospice provider or SHIP counselor for details on eligibility.
• Area Agencies on Aging (AAAs): These local organizations connect older adults and their caregivers with community services, including meal delivery, transportation, legal assistance, and caregiver support groups. You can find your local AAA through the Eldercare Locator at eldercare.acl.gov or by calling 1-800-677-1116.
• National Alliance for Caregiving: This nonprofit organization offers research, advocacy, and resources for family caregivers, including guides on managing care responsibilities and connecting with other caregivers.
• Caregiver support groups: Many hospitals, community centers, and online platforms offer support groups specifically for caregivers. Sharing your experiences with others in similar situations may help reduce feelings of isolation and provide practical advice.
• 1-800-MEDICARE (1-800-633-4227): Medicare's official helpline is available 24 hours a day, 7 days a week. Representatives can answer questions about coverage, enrollment, claims, and appeals. You can also visit Medicare.gov for plan comparisons, enrollment tools, and educational resources.

Caregiving is a role that often goes unrecognized, but the work you do makes a real difference in your loved one's health and quality of life. By understanding how Medicare works, securing the right authorizations, and taking advantage of available support programs, you can navigate this system with greater confidence — and make sure the person you care about gets the coverage they need.
