What Is Original Medicare?
Original Medicare is the federal health insurance program for people 65 and older. It has two parts — Part A hospital coverage and Part B medical coverage.
Understanding what it covers, what it costs, and what it leaves behind is the foundation of every smart Medicare decision.

The Two Parts of Original Medicare
Medicare Part A and Part B
Original Medicare has two main parts. Most people get Part A premium-free. Part B usually has a monthly premium that most people pay.
Medicare Part A — Hospital Insurance
Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services.
Most Medicare beneficiaries receive Part A premium-free because they or their spouse worked and paid Medicare taxes long enough.
| Part A Cost in 2026 | Amount |
|---|---|
| Premium with enough work history | $0/month for most people |
| Hospital deductible | $1,736 per benefit period |
| Days 1–60 coinsurance | $0 after deductible |
| Days 61–90 coinsurance | $434/day |
| Lifetime reserve days | $868/day |
| Skilled nursing days 21–100 | $217/day |
The Benefit Period Trap
The Part A deductible applies per benefit period — not per year. If you are readmitted after a benefit period resets, you could face the deductible again.
That is one reason people look at Medicare Supplement or Medicare Advantage options.
Medicare Part B — Medical Insurance
Part B covers doctor services, outpatient care, preventive services, lab tests, medical equipment, surgeries, specialist visits, and some home health services.
Everyone enrolled in Part B usually pays a monthly premium. Higher-income beneficiaries may pay more because of IRMAA.
| Part B Cost in 2026 | Amount |
|---|---|
| Standard monthly premium | $202.90/month |
| Annual deductible | $283 |
| Coinsurance after deductible | 20% |
| Annual out-of-pocket maximum | None under Original Medicare alone |
The 20% Problem
Part B generally pays 80% of approved costs after the deductible. You pay the remaining 20% — and Original Medicare by itself does not include a simple annual out-of-pocket maximum.
A major surgery, cancer treatment, or extended outpatient care could leave you with large bills if you do not have additional protection.
So Is Original Medicare Enough By Itself?
For most people, Original Medicare by itself is not the complete plan. It is the foundation. Then you decide how you want to protect yourself from the gaps.
Some people choose a Medicare Supplement plan because they want more predictable costs and the freedom to use providers that accept Medicare. Others choose Medicare Advantage because they want one plan that may include extra benefits and built-in cost protection.
There is not one perfect answer for everyone. The right choice depends on your doctors, prescriptions, budget, travel habits, and how much risk you want to keep.
