Is there a medicare plan that covers 100%?

Medicare pays 100% of inpatient hospital costs for the first 60 days (after you pay the Part A deductible) and 100% of skilled nursing facility costs for the first 20 days (with no daily coinsurance).

Original Medicare never covers 100% of all medical costs indefinitely; it always involves deductibles, copayments, or coinsurance depending on the type of care and length of stay.

Inpatient Hospital Stays (Medicare Part A)

• Days 1–60: Medicare pays 100% of approved costs after you pay the Part A deductible ($1,736 in 2026).
• Days 61–90: You pay a daily coinsurance ($434 per day in 2026), and Medicare pays the rest.
• Days 91–150: You pay a higher daily coinsurance ($868 per day in 2026) using your lifetime reserve days.
• After Day 150: You pay 100% of all costs.

Skilled Nursing Facility Stays (Medicare Part A)

• Days 1–20: Medicare pays 100% of approved costs after any applicable initial requirements.
• Days 21–100: You pay a daily coinsurance ($217 per day in 2026), and Medicare pays the balance.
• After Day 100: Medicare pays 0%, and you cover all costs.
• Note: Coverage can end before day 20 or 100 if you no longer require daily skilled care. You can learn more about these rules through the official Medicare Skilled Nursing Facility Coverage Guide. You can also read more about general financial expectations on the AARP Medicare Coverage Guide.

Medical and Doctor Services (Medicare Part B)

• For outpatient care, doctor visits, and medical equipment, Medicare Part B generally pays 80% of the Medicare-approved amount after you meet the annual deductible. You (or a supplemental Medigap policy) are responsible for the remaining 20% with no out-of-pocket maximum under Original Medicare.

Neither option is universally "better"; Original Medicare (straight Medicare) and Medicare Advantage suit different health needs, budgets, and preferences.

To decide which is right for you, compare how each option handles key factors:

Original Medicare (Parts A and B)

• Doctor Choice: You can see any doctor or go to any hospital in the U.S. that accepts Medicare. You do not need referrals to see specialists.
• Approvals: You rarely need prior authorization or permission from an insurance company for tests or treatments.
• Costs: It does not have an annual out-of-pocket maximum unless you buy a separate Medigap (Medicare Supplement) policy.
• Extras: It does not cover prescription drugs (you need a separate Part D plan) or routine dental, vision, and hearing.

Medicare Advantage (Part C)

• All-in-One Bundles: These private plans combine Part A, Part B, and usually Part D (prescription drugs), often with low or zero monthly premiums.
• Extra Benefits: They frequently include routine dental, vision, hearing, and gym memberships.
• Financial Protection: They include a mandatory annual out-of-pocket spending cap (capped at $9,250 for in-network care).
• Restrictions: You are usually limited to local provider networks (like HMOs or PPOs), and you may need referrals or prior authorization for care.

Which Should You Choose?

• Choose Original Medicare (with Medigap) if you travel often within the U.S., want the freedom to see any specialist without a referral, and prefer predictable medical bills with fewer coverage denials.
• Choose Medicare Advantage if you want lower monthly premiums, extra perks like dental or vision care, and a hard cap on your yearly out-of-pocket costs, and you are comfortable using a specific local network of doctors.

You can compare specific local options using the official Medicare Plan Finder.

The best insurance to have with Medicare depends on your health needs and budget, choosing between a Medigap (supplemental) policy for maximum doctor choice or a Medicare Advantage plan for bundled extra benefits.

You can learn more about evaluating these choices through the Consumer Reports Guide to Medicare Advantage or the Medicare.org Senior Insurance Overview.

Option 1: Original Medicare + Medigap (Supplement)

• How it works: You keep government-managed Original Medicare (Parts A and B) and buy private supplemental insurance (Medigap) to pay for things like copays, coinsurance, and deductibles. You also need a separate Part D plan for prescription drugs.
• Best for: People who want predictable medical bills and the freedom to see any doctor in the U.S. who accepts Medicare without needing referrals.
• Top providers: Humana and Mutual of Omaha are widely trusted for Medigap plans.

Option 2: Medicare Advantage (Part C)

• How it works: Private insurance companies replace Original Medicare with an all-in-one plan that bundles Part A, Part B, and usually prescription drug coverage (Part D).
• Best for: People who want lower monthly premiums and extra perks like dental, vision, hearing, and fitness memberships.
• Top providers: UnitedHealthcare, Humana, and Aetna lead the market in size, availability, and customer satisfaction ratings.

Most doctors prefer Medigap (Medicare Supplement) over Medicare Advantage because it avoids private insurance red tape.

Why Doctors Prefer Medigap

• Less Paperwork: Doctors bill Original Medicare directly, meaning faster and more predictable payments.
• No Prior Authorizations: Medigap does not require approval from a private insurance company before giving care. Studies show a vast majority of physicians are frustrated by Advantage plan pre-approval delays.
• No Network Limits: Patients can see any doctor or hospital nationwide that accepts Medicare.

Why Doctors Dislike Medicare Advantage

• Administrative Burden: Advantage plans require time-consuming referrals and pre-approvals.
• Care Denials: Private insurers often delay or deny treatments, which creates friction between the doctor and the patient.
• Restricted Networks: Doctors must navigate narrow HMO or PPO provider rules set by individual private companies.

Original Medicare does not cover four major categories of health needs: routine dental care, eyeglasses and routine eye exams, hearing aids and exams, and long-term (custodial) care.

Key Uncovered Services

• Routine Dental Care: Original Medicare excludes cleanings, fillings, tooth extractions, root canals, and dentures. It only covers very limited, specific procedures tied to another medical treatment (such as a dental exam before certain organ transplants or jaw reconstruction).
• Vision Care: Routine eye exams, eyeglasses, and contact lenses are not covered. Medicare does cover medically necessary treatments for specific eye diseases like cataracts or glaucoma, but not the glasses needed afterward.
• Hearing Care: Routine hearing tests, hearing aid fittings, and hearing aids themselves are excluded from Original Medicare. Diagnostic exams are covered only if ordered by a physician to evaluate a medical problem.
• Long-Term Care: Custodial care—such as help with daily activities like bathing, dressing, eating, or using the bathroom—is not covered when it is the main kind of care you need. Medicare Part A only covers short-term skilled nursing care after a qualifying hospital stay.

Other common exclusions include care received outside the United States, cosmetic surgery, and routine foot care. You can find comprehensive details on Original Medicare Coverage Exclusions directly from Medicare.gov.
