Learn About Medicare Options for Arizona Seniors

Understanding Medicare Parts A, B, C, and D

Medicare is a federal health insurance program designed for people age 65 and older, as well as some younger individuals with disabilities or end-stage renal disease. The program is divided into four main parts, each covering different types of care. Understanding what each part covers helps Arizona seniors understand what medical services their insurance may pay for.

Part A covers hospital insurance. This includes inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. When someone goes to the hospital and stays overnight, Part A helps pay for the room, meals, nursing care, and other hospital services. Part A also covers the first 100 days of skilled nursing facility care after a hospital stay of at least three days. Most people do not pay a monthly premium for Part A if they or their spouse paid Medicare taxes while working.

Part B is medical insurance that covers doctor visits, outpatient services, and preventive care. This includes office visits with physicians, lab tests, X-rays, mental health services, and physical therapy. Part B also covers certain pieces of medical equipment and supplies, such as wheelchairs, oxygen, and diabetic testing supplies. Part B requires a monthly premium, which changes each year. In 2024, the standard monthly premium is $164.90 for most beneficiaries, though some people with higher incomes pay more.

Part C, also called Medicare Advantage, is an alternative way to receive Parts A and B coverage through a private insurance company that contracts with Medicare. These plans often include drug coverage (Part D) and additional benefits like vision, hearing, or dental services. Part C plans have networks of doctors and hospitals, similar to Health Maintenance Organizations (HMOs) or Preferred Provider Organizations (PPOs). Beneficiaries choosing Part C must continue paying the Part B premium and may pay additional premiums for the private plan.

Part D covers prescription drug costs. This can be added to Original Medicare (Parts A and B) or may already be included in a Medicare Advantage plan. Part D plans are offered by private insurance companies approved by Medicare. They help pay for medications dispensed at pharmacies. Each Part D plan has a different list of covered drugs, called a formulary, and costs vary by plan and pharmacy.

Practical Takeaway: Arizona seniors may want to learn what services each Medicare part covers. Comparing original Medicare (Parts A, B, and D) with Medicare Advantage (Part C) plans helps determine which structure fits individual health needs and budgets. Most Arizona residents can review summaries of each part's coverage on Medicare.gov or through local resources.

Original Medicare vs. Medicare Advantage Plans in Arizona

Arizona seniors can choose between two main ways to receive Medicare benefits: Original Medicare or Medicare Advantage. Each approach works differently and offers different advantages depending on a person's health status, preferences, and budget.

Original Medicare includes Part A (hospital insurance) and Part B (medical insurance). With Original Medicare, seniors can visit any doctor, hospital, or specialist in the United States that accepts Medicare. There are no networks, so people are not restricted to a particular set of healthcare providers. Original Medicare is managed directly by the federal government. When someone with Original Medicare goes to the doctor, Medicare pays its share, and the beneficiary pays their share (called a copay or coinsurance). Beneficiaries also pay an annual deductible before Medicare begins sharing costs.

Medicare Advantage (Part C) is a managed care alternative offered through private insurance companies. These plans combine hospital and medical coverage into one plan and usually include prescription drug coverage. According to the Centers for Medicare & Medicaid Services, over 28 million people were enrolled in Medicare Advantage plans nationally as of 2023, and that number continues to grow. In Arizona, Medicare Advantage has become increasingly popular among seniors seeking plans with additional services.

Medicare Advantage plans use networks of doctors and hospitals. Beneficiaries usually must see in-network providers to receive the most coverage, similar to a private health insurance plan. Many Medicare Advantage plans include extra benefits not covered by Original Medicare, such as vision exams and eyeglasses, hearing aids, dental work, and fitness programs. These additional benefits appeal to many seniors because they address healthcare needs that Original Medicare does not cover.

Costs differ between the two options. Original Medicare has a monthly Part B premium (based on income), an annual deductible, and copays or coinsurance for services. Medicare Advantage plans may have lower or no monthly premiums than Original Medicare, but they typically have higher copays and coinsurance when services are used. Some Medicare Advantage plans have $0 premiums, which attracts seniors watching their monthly budget. However, the out-of-pocket costs when using the plan could be higher.

Another key difference is coverage outside the United States. Original Medicare covers emergency services in Canada and Mexico under certain circumstances, while most Medicare Advantage plans do not cover care outside the US. Arizona seniors who travel frequently, especially to Mexico, may find Original Medicare more practical.

Practical Takeaway: Arizona seniors can compare Original Medicare and Medicare Advantage by considering their doctor preferences, expected healthcare needs, budget, and travel plans. Those who want to see any provider without restrictions may prefer Original Medicare, while those seeking comprehensive coverage with extra benefits may explore Medicare Advantage options available in their area.

Medicare Supplement Insurance (Medigap) for Arizona Seniors

Many Arizona seniors who choose Original Medicare also purchase a Medigap policy, also called Medicare Supplement insurance. Medigap is offered by private insurance companies and designed to fill gaps in Original Medicare coverage. These policies help pay for copays, coinsurance, and deductibles that Original Medicare does not cover.

Without a Medigap policy, Original Medicare beneficiaries are responsible for significant out-of-pocket costs. For example, in 2024, the Part B deductible is $240 per year. Hospital stays under Part A have different cost structures—beneficiaries pay a deductible ($1,632 in 2024) for the first 60 days of hospitalization, then increasing daily coinsurance for longer stays. These costs add up quickly for someone with serious health conditions or frequent hospitalizations.

Medigap policies are standardized by federal law, meaning there are ten different plan types (Plans A, B, D, G, K, L, M, N, and two high-deductible versions). Each plan type offers the same benefits no matter which insurance company sells it, though prices vary by company. This standardization makes it easier for seniors to compare plans because they are comparing the same coverage across different insurers.

Plan G is currently one of the most popular Medigap options for new enrollees. Plan G covers the Part B deductible, doctor visit copays, hospital coinsurance, skilled nursing facility coinsurance, and emergency care outside the US. Plans like Plan N have lower premiums but require beneficiaries to pay some copays and coinsurance. The choice between plans often comes down to how much someone wants to pay in monthly premiums versus out-of-pocket costs when receiving care.

Arizona law allows Medigap sales year-round, but the best time to purchase is during the six-month period starting when someone first turns 65 and enrolls in Medicare Part B. During this period, called the Medigap Open Enrollment Period, insurance companies cannot deny coverage or charge more based on health status. After this period ends, insurers may consider health history and may increase premiums.

Medigap plans do not cover everything. They do not cover long-term care, dental, vision, hearing, or prescription drugs. For prescription drug coverage, beneficiaries need a separate Part D plan. Medigap also does not cover care received outside the US beyond what Original Medicare covers.

Practical Takeaway: Arizona seniors with Original Medicare may want to investigate Medigap plans to understand how much out-of-pocket costs could be reduced. Reviewing plan summaries and comparing premiums among insurers in Arizona can help seniors decide if a Medigap policy fits their healthcare needs and budget.

Prescription Drug Coverage and Part D Plans Available in Arizona

Prescription medications are a significant healthcare expense for many seniors. Medicare Part D addresses this through prescription drug insurance plans offered by private companies approved by Medicare. Understanding Part D helps Arizona seniors make informed decisions about how their medications will be covered.
