Original Medicare—also called Traditional Medicare—is the federal health insurance program made up of Part A (Hospital Insurance) and Part B (Medical Insurance). It’s the foundation most Medicare beneficiaries start with, and it’s often the first step before adding drug coverage or a Medicare Supplement (Medigap) plan.

At Medigap Sherpas, we guide you through these options—plain-English explanations, no pressure, and plans that fit how you actually use healthcare.

What Is Original Medicare?

Original Medicare is run by the federal government and lets you see any doctor or hospital in the U.S. that accepts Medicare—no referrals, no narrow HMO networks.

• Part A = Hospital Insurance
  Inpatient hospital care, skilled nursing facility (short-term/medically necessary), hospice, and some home health.
• Part B = Medical Insurance
  Doctor visits, outpatient services, preventive care, labs, imaging, durable medical equipment, and more.

Important: Original Medicare generally does not include most outpatient prescription drugs. That’s why many people add a separate Part D plan.

What Part A Covers (Hospital Insurance)

Typical services:

• Inpatient hospital stays and semi-private rooms
• Skilled nursing facility care (after a qualifying inpatient hospital stay)
• Hospice care and certain home health services

Costs (high level):

• Premium: Most people pay $0 if they’ve paid Medicare taxes long enough (typically 40 quarters).
• Deductible/Cost-sharing: There’s a per-benefit-period deductible and daily coinsurance at longer hospital or SNF stays.

What Part B Covers (Medical Insurance)

Typical services:

1. Doctor visits (primary care & specialists)
2. Outpatient surgery, ER visits, urgent care
3. Preventive care (e.g., flu shots, screenings)
4. Diagnostic tests, labs, X-rays, MRIs
5. Durable medical equipment (DME)

Costs (high level):

• Monthly premium: Set annually (varies by income).
• Deductible + Coinsurance: After the Part B deductible, you generally pay 20% coinsurance for covered services—and Original Medicare has no annual out-of-pocket maximum.

Who’s Eligible & When to Enroll

Most people qualify for Medicare at age 65. Some qualify earlier due to disability or certain conditions.

You’re typically eligible if:

• You’re 65+ and a U.S. citizen or permanent resident (long-enough work history may make Part A premium-free).
• You’re under 65 and have received Social Security Disability benefits for a qualifying period.
• You have ALS (Medicare can begin when disability benefits start).
• You have End-Stage Renal Disease and meet Medicare’s specific criteria.

Key enrollment windows:

• Initial Enrollment Period (IEP): 7-month window—3 months before the month you turn 65, your birthday month, and 3 months after.
• Special Enrollment Periods (SEPs): If you delayed Part B because you had credible employer coverage, you can enroll later with no penalty when that coverage ends.
• General Enrollment Period (GEP): If you miss your IEP/SEP, you can enroll Jan 1–Mar 31 each year (coverage start rules apply).

Why Many People Add Supplemental Coverage (Medigap + Part D)

Original Medicare is a strong base, but it leaves you with gaps:

• 20% coinsurance under Part B with no out-of-pocket cap
• Hospital deductibles and cost-sharing
• No routine outpatientprescription drug coverage (requires Part D)

Medicare Supplement (Medigap) plans help pay many of the costs Original Medicare doesn’t, improving predictability and protecting your budget. A stand-alone Part D plan adds drug coverage.

• Bottom line: Pairing Original Medicare with Medigap (and Part D) can reduce financial surprises and help you see providers nationwide without network restrictions.

Original Medicare vs. Medicare Advantage (Quick Note)

• Original Medicare + Medigap + Part D: Nationwide access to any provider who takes Medicare; you manage separate policies (Medigap and Part D) for cost protection and drugs.
• Medicare Advantage (Part C): Private plan alternative that replaces Original Medicare A & B while you’re enrolled; typically has networks and plan rules, often bundles drugs and extras (vision, dental). It’s not the same as Medigap.

If you prefer broad provider choice and predictable costs, Original Medicare + Medigap + Part D is often a good fit.
