Understanding the Differences Between Medicare Part C Plans

Home » Resources » Understanding the Differences Between Medicare Part C Plans

Medicare Part C, or Medicare Advantage, is an alternative to Original Medicare (Part A and Part B) that offers additional coverage through private insurance companies approved by Medicare. These plans combine the benefits of Parts A and B into a single plan while often providing extra services, such as prescription drug coverage (Medicare Part D) and dental or vision benefits. Medicare Advantage plans are required to cover all the services provided by Original Medicare, but they may also offer additional benefits tailored to the specific needs of their members.

Key Differences Between Medicare Part C and Original Medicare

  • Coverage: Original Medicare covers hospital stays (Part A) and medical services (Part B), whereas Medicare Advantage plans provide the same coverage as Original Medicare, but with added benefits such as prescription drug coverage, dental care, and vision services.
  • Costs: Original Medicare has standardized premiums, deductibles, and coinsurance, while Medicare Advantage plans have varying costs depending on the plan and the insurance company. Some Medicare Advantage plans even offer low or zero monthly premiums, although you may still need to pay your Part B premium.
  • Network Restrictions: Original Medicare allows you to visit any healthcare provider that accepts Medicare, while Medicare Advantage plans typically have networks of doctors and hospitals you must use to receive full benefits. However, many plans provide out-of-network coverage for emergencies or urgent care.
  • Additional Benefits: Unlike Original Medicare, Medicare Advantage plans often include extra benefits like prescription drug coverage, fitness programs, preventive care services, and hearing aids. These additional benefits can enhance your overall healthcare experience.

Types of Medicare Part C Plans

  • Health Maintenance Organization (HMO) Plans: HMO plans usually require you to choose a primary care doctor and get referrals for specialists. They typically have lower out-of-pocket costs and a designated network of healthcare providers.
  • Preferred Provider Organization (PPO) Plans: PPO plans offer more flexibility in choosing doctors and hospitals, both in-network and out-of-network. While staying in-network can save you money, you still have the option to seek care outside the network.
  • Private Fee-for-Service (PFFS) Plans: PFFS plans determine how much they will pay doctors, hospitals, and other healthcare providers, and how much you’ll be responsible for. Not all providers accept PFFS plans, so it’s important to verify if your providers are in-network.
  • Special Needs Plans (SNPs): SNPs are designed for individuals with specific health conditions or who reside in certain institutions. These plans tailor their benefits, providers, and drug formularies to meet the unique needs of the beneficiaries they serve.
  • HMO Point of Service (HMO-POS) Plans: HMO-POS plans combine features of HMO and PPO plans. They require you to choose a primary care doctor and get referrals for specialists but allow some out-of-network coverage for higher costs.

Considerations When Choosing a Medicare Part C Plan

  • Coverage and Benefits: Review the coverage and additional benefits offered by each plan, ensuring they meet your healthcare needs, including prescription drugs, vision, dental care, and other services important to you.
  • Costs: Evaluate the plan’s premiums, deductibles, copayments, and coinsurance to determine how they fit within your budget. Consider both monthly costs and potential out-of-pocket expenses.
  • Provider Networks: If you have preferred doctors or hospitals, confirm whether they are included in the plan’s network. Also, check if your medications are covered by the plan’s formulary.
  • Quality Ratings: Medicare provides quality ratings for Medicare Advantage plans based on various factors. Consider these ratings to gauge the overall performance and customer satisfaction of each plan.


Medicare Part C plans, or Medicare Advantage, offer a comprehensive and convenient alternative to Original Medicare, providing additional benefits and services that cater to individual healthcare needs.
