Understanding Medicare Plans: Government-Run, Private, and Supplemental Options
Explore the three main Medicare types: Original Medicare (government-funded), Medicare Advantage (private insurance), and Medigap (supplemental coverage). Learn how each plan works and which might suit your healthcare needs.
Medicare consists of three primary plan types: Original Medicare, a federally funded program; Medicare Advantage, offered by private insurers; and Medigap, which supplements Original Medicare coverage.
This program provides healthcare benefits primarily for individuals aged 65 and older, as well as younger people with specific disabilities or health conditions.
You may qualify for Medicare before turning 65 if you:
- have received Social Security Disability Insurance (SSDI) payments for 24 months or more
- are currently undergoing dialysis
- have a kidney transplant or are awaiting one
- have end-stage renal disease (ESRD)
- have been diagnosed with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease

Medicare vs. Medicaid
Medicaid is a separate, state-operated program funded federally that offers free or low-cost healthcare to individuals of all ages with limited income.
While both Medicare and Medicaid are federally supported, Medicaid varies by state and often covers different services. Some individuals qualify for both programs simultaneously.
Original Medicare Details
Original Medicare is primarily financed through federal funds, payroll taxes collected via FICA, and beneficiary premiums.
It includes Part A for hospital coverage and Part B for outpatient medical services. Most beneficiaries do not pay monthly premiums for Part A if they contributed to Medicare taxes during their employment years. Part B premiums are income-based.
With Original Medicare, you can visit any doctor or facility that accepts Medicare without needing plan approval. However, deductibles, copayments, and coinsurance usually apply, though subsidies may be available based on income.
Medicare Advantage Explained
Medicare Advantage (Part C) plans are private insurance options that combine hospital and medical coverage with additional benefits, often including prescription drugs, dental, vision, and hearing services.
Funding comes from beneficiary premiums and Medicare payments to private insurers, which are calculated based on expected healthcare costs and geographic location.
Common Medicare Advantage plan types include:
- Health Maintenance Organization (HMO): Requires using network providers for non-emergency care.
- Preferred Provider Organization (PPO): Offers flexibility to see providers inside or outside the network, with lower costs for in-network care.
- Private Fee-for-Service (PFFS): Allows use of any provider who accepts plan terms, with set payment rates.
- Special Needs Plans (SNPs): Designed for individuals with specific chronic conditions or diseases, tailored to their needs.
Medicare Part D: Prescription Drug Coverage
Part D plans provide prescription drug benefits, with the federal government covering roughly 75% of medication costs. Beneficiaries pay premiums, copays, and deductibles.
Administered by private insurers, Part D plans vary in coverage and costs. To enroll, you must have Medicare Part A or B and sign up during the annual enrollment period from October 15 to December 7. Late enrollment may result in penalties.
Each Part D plan must cover at least two drugs from commonly prescribed medications and include most drugs in six protected categories:
- Immunosuppressants for organ transplant rejection
- Antidepressants
- Antipsychotics
- Anti-seizure medications
- Antiretroviral drugs
- Certain chemotherapy drugs
Coverage and costs depend on the plan’s formulary tiers, with higher tiers typically costing more.
Medigap: Supplemental Medicare Insurance
Medigap policies, offered by private insurers, help cover out-of-pocket expenses not paid by Original Medicare, such as deductibles, copayments, and coinsurance.
Beneficiaries pay monthly premiums for Medigap plans. Eligibility and available plans depend on your Medicare enrollment history and state of residence. There are 10 standardized Medigap plans labeled A, B, C, D, F, G, K, L, M, and N.

Common Questions About Medicare
Do you pay premiums for both Medicare Part B and Part C?
Yes, enrollment in a Medicare Advantage (Part C) plan requires paying the Part B premium, though some Part C plans may cover this cost.
Is Medicare Part D worth enrolling in?
Part D offers valuable prescription drug coverage that can reduce out-of-pocket medication expenses. Its worth depends on your specific medication needs and plan choice.
What is the Medicare QMB program?
While there is no Medicare Part Q, the Qualified Medicare Beneficiary (QMB) program assists individuals with limited income in covering Original Medicare costs.
Final Thoughts
Choosing the right Medicare plan can be complex but offers flexibility to tailor your healthcare coverage and costs.
Review all Medicare parts carefully when first eligible to select the best plan for your needs and avoid late enrollment penalties.
