Medicare Assistance for Families: Your 2026 Open Enrollment Prep Checklist Before October 15
Medicare Open Enrollment runs from October 15 through December 7, 2026. Changes made during this period generally take effect January 1, 2027.
For many households, Medicare decisions affect more than one person. A spouse may still be working, another family member may need individual health insurance, and retirement income may influence future premiums. Reviewing coverage early gives your family time to compare options without rushing.
This guide explains the key steps to complete before October 15, including Part D and Medicare Advantage reviews, provider and pharmacy checks, income considerations, working-spouse coverage, and retirement planning.
What Can You Change During Medicare Open Enrollment?
During the annual Open Enrollment period, you can generally:
Join, drop, or switch Medicare Advantage plans
Add, drop, or change prescription drug coverage
Switch from Original Medicare to Medicare Advantage
Switch from Medicare Advantage back to Original Medicare
Join, drop, or switch a standalone Part D plan if you have Original Medicare
The official Medicare Open Enrollment page explains the available choices and provides links to Medicare’s plan comparison tools.
Open Enrollment is primarily for changing existing Medicare coverage. It is not always the correct enrollment period for someone enrolling in Medicare for the first time. If you or a spouse is approaching age 65, confirm whether the Initial Enrollment Period or a Special Enrollment Period applies.
Start Your Review Before October 15
Plan information for the upcoming year is typically available before Open Enrollment begins. Use late September and early October to organize your information.
Gather:
Your current Medicare Advantage or Part D plan documents
The Annual Notice of Change
Your Evidence of Coverage
A complete medication list
Names of doctors, hospitals, specialists, and pharmacies
Your estimated household income
Information about employer or retiree coverage
Your current monthly premiums and typical healthcare expenses
The Annual Notice of Change explains how your existing plan will change for the next year. Do not assume that automatic renewal means your premium, formulary, network, or benefits will remain the same.
1. Review Your Medicare Advantage or Part D Coverage
A plan that worked well this year may not be the best fit for 2027. Compare your current plan with available alternatives using Medicare’s Plan Compare tool.
Review more than the monthly premium. Pay attention to:
Annual deductible
Primary care and specialist copayments
Hospital costs
Out-of-pocket maximum
Prescription drug costs
Prior authorization requirements
Referral rules
Dental, vision, hearing, or other supplemental benefits
Coverage while traveling
In-network and out-of-network rules
For Medicare Advantage plans, network rules can be especially important. A plan with attractive extra benefits may create inconvenience if your preferred doctors or hospitals are not available under the plan’s network.
For Original Medicare beneficiaries, compare standalone Part D plans and consider whether supplemental coverage, such as Medigap, fits your needs. Remember that Medigap rules and enrollment opportunities are different from Part D and Medicare Advantage Open Enrollment. Review Medicare’s Medigap guidance before making a change.
2. Compare Formularies and Pharmacy Networks
Prescription coverage should be reviewed using your actual medication list, not a general estimate.
For every prescription, record:
Drug name
Dosage
Frequency
Quantity
Whether you use a brand-name or generic version
Preferred pharmacy
Any specialty pharmacy requirements
Then check each plan’s formulary. A formulary is the plan’s list of covered medications. Plans may place the same drug in different tiers, which can significantly change your cost.
Also compare pharmacy networks. Some plans offer lower costs through preferred pharmacies, mail-order programs, or specific retail locations. A plan with a slightly higher premium could still cost less overall if it covers your medications more favorably.
Ask these questions:
Are all of my prescriptions covered?
What tier is each medication assigned to?
Will I need prior authorization or step therapy?
Is my pharmacy in the preferred network?
Are 90-day supplies available?
How are specialty medications handled?
3. Confirm Your Doctors and Hospitals
Provider directories can change and may occasionally contain errors. Check the plan’s directory, then call your doctors’ offices directly.
Confirm whether the following will remain in-network for 2027:
Primary care physician
Specialists
Preferred hospital
Urgent care locations
Physical therapy or rehabilitation providers
Mental health professionals
Durable medical equipment suppliers
If you regularly travel or spend part of the year in another state, ask how the plan handles routine and urgent care outside its service area.
For Medicare Advantage plans, verify whether your providers participate in the specific plan, not merely with the insurance company generally. Different plans from the same insurer can have different networks.
4. Understand the 2026 Part D Out-of-Pocket Cap
For calendar year 2026, Medicare Part D has an annual out-of-pocket threshold of $2,100 for covered Part D prescription drugs. Once your qualifying out-of-pocket spending reaches that amount, you enter catastrophic coverage and generally pay no additional cost-sharing for covered Part D drugs for the rest of the year.
This protection applies to both:
Standalone Part D plans
Medicare Advantage plans that include prescription drug coverage
The cap does not mean every prescription expense automatically counts toward the limit. Costs for drugs excluded from your plan, medications purchased outside applicable coverage rules, and certain other expenses may be treated differently.
Because the 2026 Open Enrollment period selects coverage for 2027, review the upcoming plan’s official materials for the applicable 2027 drug cost limits, deductibles, and cost-sharing rules. Use the plan’s Summary of Benefits and Evidence of Coverage rather than relying only on advertisements or last year’s figures.
You can review current information through Medicare’s Part D costs page.
5. Consider IRMAA and Household Income
IRMAA, or the Income-Related Monthly Adjustment Amount, is an additional amount that some Medicare beneficiaries pay for Part B and Part D premiums. It is separate from the premium charged by a Medicare Advantage or Part D plan.
IRMAA is generally based on modified adjusted gross income from a tax return filed two years earlier. For example, 2026 determinations generally use 2024 income. Future 2027 determinations are expected to use 2025 income, subject to official Social Security calculations and notices.
Income can include more than wages. Consider whether the following may affect your household’s Medicare-related costs:
Retirement account distributions
401(k) withdrawals
IRA conversions
Capital gains
Bonuses
Business income
Sale of property
Investment income
If your income has changed because of retirement, divorce, loss of a pension, or another qualifying life-changing event, you may be able to request an IRMAA reconsideration through Social Security. Visit Social Security’s Medicare premium information for current guidance.
Do not estimate IRMAA using outdated tables. Check official Medicare and Social Security information for the applicable year.
6. Coordinate Coverage With a Working Spouse
A spouse who is still working may have employer-sponsored group health coverage. Whether that coverage pays first or Medicare pays first depends on factors such as employer size, current employment status, and whether the coverage is active employer coverage, retiree coverage, or COBRA.
In general:
With current employment at an employer with 20 or more employees, the employer plan commonly pays first and Medicare pays second.
With current employment at a smaller employer, Medicare may pay first and the group plan may pay second.
Retiree coverage and COBRA are not the same as active employer coverage. Medicare often pays first in those situations.
Do not decline Part B or Part D based only on a verbal explanation. Ask the employer’s benefits administrator how the plan coordinates with Medicare and whether prescription coverage is creditable.
Medicare’s Who Pays First tool can help you organize the relevant questions. If you have coverage through a spouse’s employer, contact the benefits administrator before making changes. Adding Medicare drug coverage could affect employer or union coverage for you or your dependents.
7. Plan for Individual Health Insurance Before Medicare Begins
Some households need individual health insurance help because one spouse is not yet eligible for Medicare. This commonly happens when one person retires before the other reaches age 65.
Possible sources of coverage may include:
Employer-sponsored coverage
A spouse’s employer plan
COBRA
HealthCare.gov or a state Marketplace
Medicaid, if eligible
Short-term options where permitted and appropriate
If you lose employer coverage, you may qualify for a Special Enrollment Period through the Marketplace. Start at HealthCare.gov to review current eligibility and deadlines.
Compare:
Monthly premium
Deductible
Family out-of-pocket maximum
Provider network
Prescription coverage
Eligibility for premium tax credits
HSA eligibility
The date coverage starts
When someone becomes eligible for Medicare, Marketplace coverage and financial assistance rules can change. Confirm how the transition affects every household member before ending or renewing individual coverage.
8. Include 401(k) Rollover and Retirement Income Planning
Healthcare premiums are part of the retirement budget. Before taking money from an old 401(k), review how the decision could affect both cash flow and future Medicare-related costs.
A rollover decision may involve:
Leaving funds in a former employer’s plan
Rolling funds into a new employer plan
Moving funds into a traditional or Roth IRA
Taking a taxable distribution
A direct rollover is often simpler than receiving the funds personally, but the right choice depends on taxes, fees, investment options, creditor protections, required minimum distributions, and your broader financial plan.
Retirement withdrawals may also affect income-based Marketplace assistance or future IRMAA. Coordinate with a qualified tax or financial professional before making a large distribution, Roth conversion, or rollover.
Small Business Note: Medicare-Age Employees and Group Benefits
Small business owners may have employees who continue working after becoming eligible for Medicare. Employers should provide accurate benefits communication and explain how group coverage interacts with Medicare without pressuring employees toward a particular choice.
Important review points include:
Whether the group plan provides creditable prescription drug coverage
How the plan coordinates with Medicare
Whether employees need to notify the benefits administrator
How dependent coverage could be affected
Health Savings Account contribution rules
Benefits communication before an employee turns 65
This is an area where employee benefits consulting and HR consulting for small business can help. A consultant can support benefits administration, employee communication, compliance processes, and consistent retirement-transition procedures.
DATC Consulting Group provides employee benefits consulting and human resources guidance for small businesses developing practical benefits strategies.
