🩺 What is Medicare?

Medicare is a U.S. federal health insurance program that helps pay for hospital and medical care. It’s especially for people who are:

• Age 65 or older, and
• Younger people with certain disabilities, or
• People with End-Stage Renal Disease (permanent kidney failure needing dialysis or transplant). �

Medicare helps pay for things like hospitals, doctors, outpatient care, and some health services, but you usually still pay things like deductibles, premiums, and coinsurance.

👥 Who “buys” Medicare?

Medicare isn’t like private insurance you choose from a company. But people must enroll and usually pay:

•Monthly premiums for Parts B and D, if they want that coverage.
• Part A premium in some cases — if you haven’t worked long enough (40 quarters) to get it for free.

So, you don’t buy it like a normal insurance plan, but you pay premiums/deductibles based on your eligibility and choices.

💵 Medicare Costs & Deductibles in 2026

🔹 Part A – Hospital Insurance

Premium
Most people pay $0 because they worked and paid Medicare taxes long enough.

If you don’t qualify for free Part A, you can buy it:

• $311 per month (if you have 30–39 quarters of work history)
• $565 per month (if you have fewer than 30 quarters)

Deductible

$1,736 per benefit period before Medicare starts paying for inpatient hospital care in 2026.

🔹 Part B – Medical Insurance (Doctors, Outpatient)
Monthly Premium

• $202.90 in 2026 for most people (income affects this amount — higher incomes pay more).

Annual Deductible

•$283 for 2026 before Medicare starts paying for most Part B services.

After you meet the deductible

• You usually pay 20% coinsurance of the Medicare-approved amount for Part B services.

🔹 Part D – Prescription Drug Coverage (optional)

• Premiums and deductibles vary by plan you choose.
• In 2026, many Part D plans have deductibles, coinsurance, and a maximum out-of-pocket drug cost limit (for many plans ~ $2,100).

🧠 Summary
• Medicare is U.S. government health insurance mainly for those 65+ or with qualifying conditions.
• You don’t buy it like normal insurance, but you pay premiums, deductibles, and coinsurance depending on your coverage.

In 2026, the key deductible figures are:
• $1,736 (Part A)
• $283 (Part B)
