Key takeaway: Most people get Medicare Part A (hospital insurance) for free because they or their spouse worked and paid Medicare taxes for at least 10 years — but if you haven't, you could owe up to $565 per month just for the coverage itself, before any hospital bills.
What this helps you decide
- Whether you qualify for premium-free Part A based on your own work history or your spouse's
- How much you'll pay per month if you have fewer than 40 quarters of Medicare-covered work
- What the Part A deductible and hospital coinsurance cost you once you're actually admitted — the premium is just the beginning
- Whether it makes financial sense to "buy into" Part A, especially if you're not eligible for premium-free coverage and are considering other health insurance options
Who this is for
- Someone who worked outside the U.S. for a significant portion of their career, or in a job not covered by Social Security and Medicare taxes
- A spouse who stayed home to raise children or did not work in the formal economy and isn't sure if they qualify based on their partner's work record
- A self-employed person or freelancer who wants to verify their quarter count before turning 65
- Anyone who received an unexpected Part A premium amount from Social Security and wants to understand how it was calculated
What is a "quarter of coverage"?
A quarter of coverage — sometimes called a "work credit" — is the unit Medicare uses to measure your work history. In 2026, you earn one quarter of coverage for every $1,810 in wages or self-employment income you report, up to a maximum of four quarters per year. You don't have to earn the money in a literal quarter of the calendar year — you could earn all four credits in January and you'd still get four credits for the year.
To earn premium-free Part A, you need 40 quarters total, which works out to 10 years of work at any level above $1,810 per quarter. The quarters don't have to be consecutive. A few summers of part-time work in your 20s count the same as full-time employment later in life, as long as the earnings were subject to Medicare taxes.
Example results
Example 1 — 40 or more quarters (most people). If you worked in Medicare-covered employment for 10 or more years, you've already paid into the system through payroll taxes. Your Part A premium in 2026 is $0 per month. You've earned it. This applies to the vast majority of people turning 65 — according to Social Security data, roughly 99% of Medicare beneficiaries qualify for premium-free Part A.
Even if you personally don't have 40 quarters, you may qualify through your spouse's record. If your spouse (current, divorced after 10+ years of marriage, or deceased) has 40 quarters, you can get premium-free Part A based on their work history.
Example 2 — 30 to 39 quarters. Say you have 35 quarters of Medicare-covered work — maybe you worked part-time for several years, had a long gap in employment, or worked in a non-covered job early in your career. In 2026, your Part A premium is $311 per month, which works out to $3,732 per year. You'll pay this every month you have Part A without having earned the full 40 quarters. Over five years, that's $18,660 just for the coverage, before any hospital costs.
If you're in this situation and you're still working, it's worth checking how many quarters you still need to reach 40. You may be closer than you think. Your Social Security statement (available at ssa.gov) shows your quarter count.
Example 3 — Fewer than 30 quarters. If you have 15 quarters of covered work — maybe you came to the U.S. later in life, spent most of your career overseas, or worked primarily in jobs not subject to Medicare taxes — your Part A premium in 2026 is $565 per month, or $6,780 per year. That's a substantial cost on top of everything else Medicare involves. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents.
If you're in this situation, it's worth considering whether enrolling in Part A makes financial sense without other Medicare coverage, or whether a different health insurance approach (such as marketplace coverage or delaying Medicare enrollment while continuing employer coverage) might be more cost-effective.
Part A hospital costs once you're enrolled
Whether or not you pay a premium, the Part A deductible and coinsurance apply whenever you're actually hospitalized. These are per-benefit-period costs, not per-year — meaning they can reset if you've been out of the hospital for 60 consecutive days.
- Hospital deductible (days 1–60): $1,736 per benefit period in 2026. This covers the first 60 days of an inpatient stay.
- Days 61–90 coinsurance: $434 per day in 2026. If your stay runs longer than 60 days, you owe $434/day for each day from day 61 through day 90.
- Lifetime reserve days (days 91+): $868 per day in 2026. You have 60 lifetime reserve days total across your entire Medicare lifetime. Once those are gone, Medicare pays nothing for inpatient care beyond 90 days per benefit period.
- Skilled nursing facility (SNF) coinsurance, days 21–100: $194.50 per day in 2026. The first 20 days of SNF care are covered fully; days 21–100 carry this daily coinsurance; after day 100, Medicare stops paying.
If you have Original Medicare without Medigap, these costs are entirely your responsibility. Medigap Plan G covers the hospital deductible, the days 61–90 coinsurance, the lifetime reserve daily coinsurance, and the SNF coinsurance — which is a big reason people buy it.
Sample scenarios
| Scenario | Input | Result |
|---|---|---|
| 40+ quarters of covered work | Worked in Medicare-covered employment for 10+ years | $0/mo premium — Part A is free |
| 30–39 quarters (e.g., 35 quarters) | Worked ~8.75 years in covered employment | $311/mo — $3,732/yr for Part A coverage |
| Fewer than 30 quarters (e.g., 15 quarters) | Limited U.S. work history or non-covered employment | $565/mo — $6,780/yr for Part A coverage |
| 5-day hospital stay, no Medigap, premium-free Part A | Inpatient admission, days 1–5 | $1,736 Part A deductible — all of it owed for the full benefit period |
What to do next
- Check your quarter count at ssa.gov. Log in to your my Social Security account and look at your Social Security statement. It shows your total work credits and your earnings history. If you're short of 40 quarters, you'll see exactly how close you are.
- If you're close to 40 quarters, consider working a bit longer. If you have 38 or 39 quarters, a few months of part-time or self-employment work earning at least $1,810 per quarter can get you to premium-free Part A. That saves you $311/month for life — a strong incentive.
- If you're married, check your spouse's record. You may qualify for premium-free Part A based on your spouse's work history even if you don't have 40 quarters yourself. This applies to current spouses, divorced spouses (if the marriage lasted 10+ years), and surviving spouses.
- If you'll owe a premium, plan for it in your retirement budget. A $311 or $565 monthly Part A premium is a real cost that needs to be in your retirement income projections. Pair this with your Part B premium ($202.90/month) and any Medigap or MA plan premium to get your full Medicare budget.
Key facts
- In 2026, you need 40 quarters (10 years) of Medicare-covered work to qualify for premium-free Part A. If you have 30–39 quarters, you pay $311/month; if you have fewer than 30, you pay $565/month.
- The Part A hospital deductible is $1,736 per benefit period in 2026 — not per year. A benefit period resets after 60 consecutive days out of a hospital or skilled nursing facility, so you could owe this deductible more than once in a calendar year.
- You can qualify for premium-free Part A through a current or former spouse's work record if they have 40 or more quarters, even if you have zero Medicare-covered work yourself.
