Helping a Parent Enroll in Medicare: A Guide for Adult Children

You Are Not Alone in This#

If you are reading this because your parent is approaching 65 — or because they retired and Medicare suddenly became urgent — you are in a very common situation. Adult children often become the de facto Medicare project manager: sorting mailers, fielding sales calls, and trying to figure out whether Original Medicare, Medicare Advantage, or a supplement plan makes sense.

This guide is written for you. It will not replace a personalized plan review, but it will help you ask the right questions and avoid the most expensive mistakes.

Step 1: Confirm Their Enrollment Timeline

Medicare has strict windows. Missing them can mean lifelong premium penalties or coverage gaps.

Initial Enrollment Period (IEP): This is the 7-month window around their 65th birthday — starting 3 months before their birthday month, including their birthday month, and ending 3 months after.

If they already receive Social Security: They are usually enrolled automatically in Part A and Part B. Confirm the start date on their Medicare card.

If they are not yet on Social Security: They must actively enroll in Part B through Social Security (ssa.gov/medicare).

Mark these dates on a shared family calendar. The penalty for late Part B enrollment is 10% added to their premium for every 12-month period they were eligible but did not enroll.

Step 2: Check Whether They Can Delay Enrollment

Before enrolling in Part B, confirm whether your parent has creditable employer coverage. The rules depend on employer size:

Large employer — 20 or more employees
The employer plan is usually primary. Part B may be delayed without a late-enrollment penalty — but get written confirmation from HR before assuming.

Small employer — fewer than 20 employees
Medicare is usually primary. Enroll in Part B at 65 to avoid coverage gaps and potential penalties.

Ask their HR department for a written statement confirming whether their coverage is creditable for Medicare Part B and Part D purposes. Do not rely on verbal assurances alone.

If your parent has retiree coverage or COBRA, the rules differ — get professional guidance before making any enrollment decisions.

Step 3: Gather the Information You Will Need

Before comparing plans, collect:

• Full list of doctors and specialists (including names and locations)
• Complete medication list (drug name, dosage, pharmacy used)
• Preferred hospitals (especially important in rural or military communities)
• Budget preferences (low monthly premium vs. predictable out-of-pocket costs)
• Travel plans (do they spend months in another state each year?)

This information determines which plan type actually works — not the marketing brochure.

Step 4: Understand the Two Main Paths

Most beneficiaries choose one of two paths:

Path A: Original Medicare + Medicare Supplement (Medigap) + Part D

• See any doctor who accepts Medicare nationwide
• Predictable medical costs (especially with Plan G)
• Requires managing multiple cards and premiums
• Higher monthly premium than most Advantage plans

Path B: Medicare Advantage (Part C)

• One card for medical, hospital, and usually prescriptions
• Often lower or $0 additional monthly premium
• Must use plan networks; prior authorizations may apply
• Out-of-pocket costs vary by plan and usage

Neither path is inherently better. The right choice depends on your parent's specific situation.

Step 5: Protect Them From Common Scams and Pressure

Medicare open enrollment and the Initial Enrollment Period attract aggressive marketing. Help your parent understand:

• Medicare will never call unsolicited to sell you a plan
• No one can "upgrade" their Medicare over the phone without their consent
• They do not have to switch plans just because they received a mailer
• One independent advisor who compares multiple carriers is safer than responding to dozens of sales calls

Consider setting up a family rule: no enrollment decisions without reviewing options together first.

Step 6: Know When to Get Professional Help

You do not need to become a Medicare expert. But you should get help when:

• Your parent has a chronic condition requiring multiple specialists
• They take more than 3–4 prescription medications
• They are transitioning from employer coverage, TRICARE, or VA benefits
• They split time between two states
• The enrollment deadline is within 60 days and you still have not decided

An independent Medicare advisor can compare plans across multiple carriers at no cost to your parent — the same premium applies whether they enroll alone or with guidance.

What You Can Do Today

1. Confirm your parent's 65th birthday and calculate their Initial Enrollment Period dates
2. Ask HR (if still employed) for creditable coverage documentation
3. Start the doctor and prescription list
4. Schedule a no-cost Medicare review with an independent advisor

Helping a parent navigate Medicare is one of the most meaningful things you can do for their financial and health security. Take it one step at a time — and do not hesitate to ask for help.
