Understanding the parts of Medicare

Before you worry about dates or plan names, it helps to know what each letter actually covers. Original Medicare is Parts A and B — everything else builds on top of that.

A

Part A — Hospital

Covers inpatient hospital stays, skilled nursing care, hospice, and some home health. Most people get it premium-free after working and paying Medicare taxes for at least 10 years.

B

Part B — Medical

Covers doctor visits, outpatient care, preventive services, and durable medical equipment. Comes with a monthly premium that's set by Medicare each year.

C

Part C — Advantage

An all-in-one private alternative to Original Medicare. Often bundles prescription drug coverage and extra benefits, usually within a provider network.

D

Part D — Drug Coverage

Covers prescription drugs. Sold by private insurers, either as a stand-alone plan or bundled into a Medicare Advantage plan.

G

Medigap (Supplement)

Private insurance that works alongside Original Medicare to help pay costs it leaves behind, like the Part B 20% coinsurance.

Month-by-Month Roadmap

What to do before you turn 65

The goal is not to do everything at once. Handle the decisions in the right order so your coverage can start when you expect it to.

6 mo.

Review work coverage & HSA rules

Find out whether you expect to retire at 65 or keep working. Check employer coverage, prescription coverage, and HSA implications early.

3 mo.

Your IEP usually opens

If you are not automatically enrolled and you plan to start Medicare at 65, this is when many people can apply for Part A and Part B through Social Security.

2 mo.

Compare your coverage path

Decide whether to compare Original Medicare with Medigap and Part D or Medicare Advantage. Check doctors, prescriptions, pharmacy, travel, and budget.

1 mo.

Confirm effective dates

Finalize the private coverage you want to begin with Medicare, verify start dates, and keep your Medicare number and Part A/Part B dates handy.

65

Coverage may begin

If you enrolled before your birthday month, Part B generally starts the month you turn 65. If you enroll during or after that month, coverage generally starts the next month.

Important: The seven-month Initial Enrollment Period generally starts three months before the month you turn 65 and ends three months after. If your birthday is on the first day of a month, Medicare timing can shift one month earlier.

Official timing references: Medicare.gov — when coverage starts and Social Security — signing up for Medicare.

Five steps, a lot of dates — totally normal to want a second set of eyes on this.

Still Working?

Your Medicare path may be different

Do not automatically enroll in Part B — and do not automatically delay it. Active employer coverage, employer size, who pays first, drug coverage, and HSA contributions can all change the answer.

Review My Work Coverage
Two paths splitting apart, representing the different Medicare enrollment paths for people still working

Active employer coverage

If coverage is based on your or your spouse's current employment, you may qualify for a Part B Special Enrollment Period later. Employer size can affect whether Medicare or the employer plan pays first.

20 or more employees: the group plan is generally primary, so you can usually delay Part B without a late penalty as long as that coverage continues. Fewer than 20 employees: Medicare is generally primary, so most people still need to enroll in Part B at 65.

Ask your benefits administrator how the plan coordinates with Medicare before you decide.

COBRA or retiree coverage

COBRA and retiree coverage are not treated the same as health coverage based on current employment for Part B enrollment timing.

If employment has ended, check your Part B deadline promptly instead of assuming COBRA or retiree coverage protects you from a late-enrollment problem.

Using an HSA? Medicare says that if you are working past 65 and delaying Medicare, you and your employer should stop HSA contributions 6 months before you retire or apply for Social Security/Railroad Retirement benefits. Premium-free Part A can be retroactive up to 6 months when you enroll after 65, which can create HSA tax issues.

Official references: Medicare.gov — working past 65 and Medicare.gov — COBRA coverage.

After Part A & Part B Timing

Choose how you want to receive your Medicare coverage

This is where the plan decision belongs — after you know your enrollment timing and how any employer coverage fits.

Path 1

Original Medicare + Medicare Supplement + Part D

You keep Original Medicare for hospital and medical coverage, add a Medigap policy to help with certain out-of-pocket costs, and usually add a separate Part D plan for prescriptions.

  • Use providers nationwide who accept Medicare
  • Compare Medigap plan letters and premiums
  • Choose a separate Part D drug plan
  • Consider monthly premium versus predictable medical costs
Explore Medicare Supplement

Path 2

Medicare Advantage (Part C)

You receive your Medicare benefits through a private Medicare Advantage plan. Plans can vary by ZIP code and may include prescription drug coverage and additional benefits.

  • Check your exact doctor and hospital network
  • Review prescriptions and preferred pharmacies
  • Compare copays, deductibles, and annual out-of-pocket limits
  • Review plan extras only after the medical coverage fits

Avoid Common Problems

Three mistakes worth preventing before 65

Most turning-65 problems are timing or coordination problems — not complicated insurance math.

1

Assuming COBRA or retiree coverage works like active job coverage

Part B Special Enrollment rules are tied to health coverage based on current employment. COBRA and retiree coverage require different timing decisions.

2

Missing the HSA and retroactive Part A issue

If you delay Medicare past 65, premium-free Part A can be retroactive up to 6 months. HSA contributions during a retroactive Medicare period can create tax problems.

3

Choosing coverage before checking doctors and prescriptions

A plan can look good on premium or extra benefits and still be a poor fit if your doctors, drugs, pharmacy, or travel needs were never checked.

Common Questions

Turning 65 and new to Medicare: common questions

For many people, the Medicare Initial Enrollment Period begins 3 months before the month they turn 65, includes their birthday month, and ends 3 months after. If your birthday is on the first day of the month, your timing may start earlier.
It depends on your employer coverage, whether the coverage is based on current employment, employer size, whether your drug coverage is creditable, and whether you contribute to an HSA. Do not assume you should automatically enroll or automatically delay.
If you miss the wrong enrollment window and do not have qualifying coverage, you may face delayed coverage and possible late enrollment penalties. The rules can differ depending on whether you are still working and what coverage you have.
If you are already receiving Social Security benefits before 65, you may be automatically enrolled in Medicare. If you are not receiving Social Security benefits, you may need to enroll yourself.
Yes. Lehigh Partners Senior Benefits can help compare Medicare Advantage, Medicare Supplement, and Part D options based on your doctors, prescriptions, pharmacy, ZIP code, budget, and coverage preferences.
