New to Medicare, the four things to know before you sign up

Last reviewed June 11, 20263 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team

Turning 65 comes with a stack of mail, a deadline nobody clearly explains, and a decision that quietly shapes your costs for years. It is genuinely a lot, and most of the regret people feel later traces back to a handful of things they wish someone had told them up front. This page is that short list. Each item links to a fuller page if you want the detail, but if you read only one thing before you sign up, read this.

1One: your enrollment window is real, and missing it is permanent

Your Initial Enrollment Period is seven months long: the three months before the month you turn 65, your birthday month, and the three months after. This is the window to sign up without a penalty, and it is the one deadline that carries a lasting price. Miss it without a valid reason and you can face a late-enrollment penalty on Part B that is added to your premium for as long as you have Medicare, not a one-time fee but for life.

Two practical notes. Enroll in the first three months of the window if you want coverage in place the day you turn 65, because signing up later pushes your start date back. And if you are still working with employer coverage, there is a legitimate way to delay (item four); this penalty is for people who simply miss the window, not for people who delay correctly.

2Two: decide your path, because it is hard to undo later

This is the decision that matters most, and the reason to think about it now is that one direction is much easier to enter than to leave. There are two broad paths: Original Medicare plus a Medigap supplement plus a standalone drug plan (wide provider access and predictable costs, at a higher monthly premium), or a Medicare Advantage plan (bundled coverage, often including drugs and extras, usually at a lower premium but within a network).

Neither is the universal right answer. The reason to decide deliberately is the underwriting trap: when you first enroll you generally have a guaranteed right to buy a Medigap policy, but if you start on Advantage and later want to switch to Original Medicare with a supplement, you may have to pass medical underwriting and can be turned down. The door is wide open at the start and can narrow later.

Original + Medigap + Part D
  • Wide provider access, no network
  • Predictable costs, higher monthly premium
Medicare Advantage
  • Bundled, often with extras, lower premium
  • Within a network; costs vary as you use care

3Three: nothing is automatic unless you are already drawing Social Security

People miss their window because they are waiting for a signal that never comes. If you are already receiving Social Security before 65, you are usually enrolled in Parts A and B automatically and a card arrives in the mail. If you are not yet drawing Social Security, nothing happens on its own: no card, no letter, no prompt, and the responsibility to enroll during your window is entirely yours. If you are not certain which group you are in, assume you have to act.

Nothing is automatic

If you already draw Social Security at 65, a card arrives in the mail. If you are not yet drawing it, nothing happens on its own, no card, no letter, no prompt, and enrolling in your window is entirely on you. If unsure, assume you have to act.

4Four: Medicare does not cover everything, so plan for the gaps

The last surprise is what Medicare leaves out. Original Medicare has no annual cap on what you can pay out of pocket, which is the main reason most people add either a Medigap supplement or an Advantage plan rather than going with Parts A and B alone. It also does not cover routine dental, vision, or hearing, and it does not cover long-term custodial care. None of these gaps is a reason to panic, but each is a reason to plan, because the time to arrange coverage for a gap is before you are standing in it.

One more thing: there is free, unbiased help. Every state has a SHIP (State Health Insurance Assistance Program) that offers no-cost Medicare counseling, and a licensed agent can walk you through the choices at no cost. Using that help is how a lot of people get the first decision right.

Common questions about Medicare

Quick answers to common questions

Tap any question to expand. Each question links to a fuller standalone answer.

Does Medicare cover durable medical equipment?

Yes.

Medicare Part B covers durable medical equipment (DME): reusable medical gear your doctor prescribes for use at home, such as wheelchairs, walkers, hospital beds, oxygen equipment, CPAP machines, and blood sugar monitors. You pay 20% of the Medicare-approved amount after the $283 Part B deductible in 2026, and Medicare pays the other 80%. To be covered, the item must be ordered by a Medicare-enrolled doctor and supplied by a Medicare-enrolled supplier, and some items are rented rather than bought. Equipment meant mainly for use outside the home, or only for comfort or convenience, is not covered.

Does Medicare cover mental health services?

Yes.

Medicare covers mental health care across its parts in 2026. Part B covers outpatient services like therapy, counseling, and visits with psychiatrists, psychologists, and clinical social workers, and since 2024 it also covers marriage and family therapists and mental health counselors. You pay 20% of the Medicare-approved amount after the $283 deductible, and one depression screening each year is free. Part A covers inpatient mental health care, with a lifetime limit of 190 days in a freestanding psychiatric hospital. Part D covers most mental health medications. Many of these services are also available by telehealth, and Medicare Advantage plans cover at least the same benefits.

Does Medicare cover vision care?

Mostly no for routine care.

In 2026, Original Medicare does not cover routine eye exams for glasses or contact lenses, and it does not pay for the glasses or contacts themselves. It does cover some medical eye care: yearly glaucoma screenings for people at high risk, diabetic retinopathy exams, treatment for eye diseases, and cataract surgery (including one pair of standard glasses or contacts afterward). For those covered services you pay 20% after the $283 Part B deductible. Many Medicare Advantage plans add a routine vision benefit covering eye exams and an allowance for glasses.

Does Medicare cover physical therapy?

Yes.

Medicare Part B covers outpatient physical therapy that is medically necessary to treat your condition. You pay 20% of the Medicare-approved amount after the yearly Part B deductible ($283 in 2026). There is no longer a hard dollar cap on therapy, but once your physical and speech therapy together pass $2,480 in 2026, your therapist must add a note (called a KX modifier) confirming you still need care. Claims above $3,000 may be reviewed for medical necessity. Part A covers physical therapy you receive as a hospital inpatient or in a skilled nursing facility. A doctor or therapist must set up and regularly review your plan of care.

Does Medicare cover chiropractic care?

Partly.

Medicare Part B covers one specific chiropractic service: manual manipulation of the spine to correct a subluxation (when one or more bones of the spine are out of position) that a doctor confirms is medically necessary. You pay 20% of the Medicare-approved amount after the $283 Part B deductible in 2026. Medicare does not cover other services a chiropractor might offer, such as X-rays, massage therapy, acupuncture, or routine wellness visits, so you would pay the full cost for those. Some Medicare Advantage plans include extra chiropractic or wellness benefits beyond this.

Does Medicare cover ambulance services?

Yes, in limited situations.

Medicare Part B covers emergency ambulance transportation when traveling any other way could endanger your health, taking you to the nearest appropriate hospital or facility. You pay 20% of the Medicare-approved amount after the $283 Part B deductible in 2026. Air ambulance is covered only when ground transport cannot reach you or would take too long. Non-emergency ambulance trips, for example to dialysis, are covered only when a doctor provides a written order stating they are medically necessary. Medicare does not cover ambulance rides taken purely for convenience.

Does Medicare cover skilled nursing facility care?

Yes, on a short-term basis.

Medicare Part A covers skilled nursing facility (SNF) care after a qualifying inpatient hospital stay of at least 3 days, when you need daily skilled care like nursing or therapy. In 2026 you pay $0 for days 1 through 20 of each benefit period, $217 per day for days 21 through 100, and all costs after day 100. Coverage is for skilled care while you recover, not for long-term or custodial care (help with daily activities like bathing or dressing), which Medicare does not cover. Long-term nursing home care is generally paid through Medicaid or private funds.

Does Medicare cover hearing aids?

No, not under Original Medicare.

In 2026, Original Medicare (Parts A and B) does not pay for hearing aids or the exams to fit them. Part B does cover diagnostic hearing and balance exams when your doctor orders them to help diagnose or treat a medical condition, and for those you pay 20% after the $283 deductible. Many Medicare Advantage plans, however, include a hearing benefit that helps pay for routine hearing exams and hearing aids, often through a specific network or allowance. If hearing coverage matters to you, it is worth comparing Advantage plans or a standalone hearing plan.

Does Medicare cover home health care?

Yes, when you qualify.

Medicare Parts A and B cover home health care if a doctor certifies that you are homebound (leaving home takes a major effort) and need part-time skilled care, such as skilled nursing, physical therapy, occupational therapy, or speech therapy. A Medicare-certified home health agency must provide the care under a plan your doctor reviews. You pay $0 for covered home health visits in 2026, and 20% for any durable medical equipment. Medicare does not cover 24-hour home care, meal delivery, or homemaker services like cleaning when that is the only care you need.

Does Medicare cover diabetes supplies and testing?

Yes.

In 2026 Medicare covers most diabetes care across two parts. Part B (outpatient care and equipment) covers blood sugar monitors, test strips, lancets, and continuous glucose monitors (CGMs) as durable medical equipment, plus diabetes screenings and a self-management training program. You pay 20% of the Medicare-approved amount after the $283 Part B deductible. Part D (drug coverage) covers insulin and related supplies like syringes, and in 2026 your insulin is capped at $35 for a month's supply. If you have a Medicare Advantage plan, it covers at least the same diabetes benefits, sometimes with added extras.

Which is better, Medigap or Medicare Advantage?

Neither is better for everyone; they suit different needs.

Medigap (also called Medicare Supplement, a private policy that pairs with Original Medicare) lets you see any doctor nationwide who accepts Medicare with no network and very predictable out-of-pocket costs, but you pay a monthly Medigap premium and add a separate Part D drug plan. Medicare Advantage (Part C, your Medicare benefits through a private plan) often has a lower or $0 plan premium, bundles drug coverage and extras like dental and vision, and caps your yearly out-of-pocket costs, but uses provider networks and may require prior approval. People who travel, want maximum doctor freedom, and prefer steady costs often lean Medigap; people who want low premiums, extras, and a network they are comfortable with often lean Medicare Advantage. With both, you still pay the Part B premium ($202.90 per month in 2026).

Can I see out-of-network doctors on a Medicare Advantage PPO?

Yes.

A Medicare Advantage PPO (Preferred Provider Organization plan, where your Medicare benefits come through a private plan) lets you see doctors and hospitals outside the plan's network, but you usually pay more for out-of-network care than for in-network care. Staying in network keeps your costs lower, while going out of network is allowed and can be worth it if you want a specific provider. This flexibility is a key difference from a Medicare Advantage HMO (Health Maintenance Organization plan), which generally only covers in-network care except in emergencies. With a PPO, you also typically do not need a referral to see a specialist. Keep in mind the provider must accept the plan and Medicare. Emergency and urgent care are covered regardless of network on both plan types. The trade-off with a PPO is more freedom in exchange for generally higher costs than an HMO.
