Do you get Medicare automatically?

No, Medicare does not cover 100% of hospital bills for seniors.

While Original Medicare Part A covers inpatient hospital care, you still have out-of-pocket costs.

Part A Hospital Costs (2026)

• Deductible: You must pay a Part A deductible of $1,736 per benefit period before Medicare starts paying.
• Daily Coinsurance: Days 1 through 60 have $0 additional costs after the deductible. However, stays from days 61 to 90 require a $434 daily coinsurance, and days 91 to 150 (lifetime reserve days) cost $868 per day.
• After 150 Days: You must pay 100% of all costs.

Doctor and Outpatient Bills

• Part B Services: Doctors who treat you in the hospital bill separately under Part B. You must pay an annual deductible ($283) plus a 20% coinsurance for doctor services.
• Observation Status: If a hospital places you under "observation" instead of admitting you as an official inpatient, your stay is billed under Part B. This means you pay 20% for each individual service, and it may not qualify you for subsequent skilled nursing coverage.

How to Reduce Out-of-Pocket Expenses

• Medigap: You can purchase a private Medicare Supplement Insurance policy to cover deductibles and coinsurance.
• Medicare Advantage (Part C): These private plans replace Original Medicare and include a yearly out-of-pocket maximum limit.

Yes, you can receive both Social Security and Medicare at the same time.

How They Work Together

• Separate Programs: Social Security provides monthly cash income for retirement or disability, while Medicare provides federal health insurance.
• Simultaneous Receipt: Most eligible people aged 65 or older (or those with qualifying disabilities) get both programs at the same time.
• Automatic Enrollment: If you are already collecting Social Security benefits when you turn 65, you are automatically enrolled in Medicare Parts A and B.
• Premium Deductions: If you receive Social Security benefits when you enroll in Medicare, your Medicare Part B (medical insurance) premiums are usually deducted directly from your monthly Social Security check.

Key Rules

• Different Age Triggers: You can claim early Social Security retirement benefits starting at age 62, but standard Medicare eligibility does not begin until age 65 (unless you qualify early due to a disability).
• Independent Choices: You can delay taking Social Security benefits past age 65 while still signing up for Medicare at age 65, though you will have to pay your Medicare premiums directly rather than through a deduction. You can visit the Social Security Administration to manage your options.

Original Medicare (Parts A and B) does not cover several major healthcare needs, most notably routine dental care, eye exams and glasses, hearing aids, long-term custodial care, care outside the U.S., and cosmetic surgery.

Key Uncovered Services

• Routine Dental Care: Original Medicare excludes routine cleanings, fillings, tooth extractions, root canals, and dentures.
• Vision Care: Routine eye exams, eyeglasses, and contact lenses are not covered, except for specific post-cataract surgery needs or certain diabetic eye exams.
• Hearing Aids: Routine hearing exams, fittings, and hearing aids are completely excluded from standard coverage.
• Long-Term Care: Medicare pays for short-term skilled nursing, but it does not cover ongoing custodial care (help with daily activities like bathing, dressing, or eating) in a nursing home or at home.
• Care Outside the U.S.: Medical treatment received while traveling or living abroad is generally not covered.
• Cosmetic Surgery: Elective procedures meant to alter appearance rather than treat a specific illness or injury are excluded.

You can review the official breakdown of excluded services directly on the Official Medicare Coverage Guide.

Most people do not pay a premium for Medicare Part A if they or their spouse worked and paid Medicare taxes for at least 10 years (40 quarters).

Almost everyone must pay a standard monthly premium for Medicare Part B, but certain groups receive financial assistance that covers or eliminates these costs.

Premium-Free Medicare Part A

You get premium-free Part A if you meet any of these rules:

• You or your spouse worked and paid Medicare taxes for at least 10 years.
• You are eligible for or receive Social Security or Railroad Retirement benefits.
• You worked as a government employee in a job where you paid Medicare taxes.

Who Receives Help With Part B Premiums

While standard Part B premiums are required for most enrollees, specific programs pay the premium for low-income individuals:

• Qualified Medicare Beneficiary (QMB) Program: State programs that pay Part A and/or Part B premiums, deductibles, and coinsurance for low-income individuals.
• Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI) Programs: State programs that help pay the Part B premium.
• Medicaid: Low-income beneficiaries who qualify for both Medicare and full Medicaid receive assistance with their medicare costs.
• Extra Help Program: Helps eliminate or reduce prescription drug plan (Part D) premiums for qualifying low-income individuals. You can check guidelines via the National Council on Aging.

The biggest mistake seniors make when enrolling in Medicare is missing key enrollment deadlines, which can lead to permanent, lifelong late-enrollment penalties and gaps in medical coverage.

Top Medicare Enrollment Mistakes

• Missing the Initial Enrollment Period (IEP): Your window to sign up is a 7-month period that starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. Missing this window without qualifying for a special enrollment period leads to delays and penalties.
• Failing to Understand Work Rules: Many seniors either sign up for Part B when they don't need to (because they are still working and covered by an employer with 20 or more employees) or fail to realize they must sign up when they retire, missing their 8-month special window.
• Ignoring Prescription Drug Coverage (Part D): Failing to sign up for Part D when first eligible—even if you take no medications—can trigger a permanent 1% penalty added to your monthly premium for every month you delayed.
• Confusing Advantage and Supplement Plans: Assuming a low-premium Medicare Advantage plan always means lower overall out-of-pocket costs without checking network restrictions, copays, and prior authorization rules. You can read more details on avoiding these errors via the AARP Medicare Guide.
