Understanding Medicare — Parts A, B, C, and D Explained
Medicare is the federal health insurance program for Americans aged 65 and older, as well as certain younger individuals with qualifying disabilities. While Medicare is an incredibly valuable benefit, it can also be genuinely confusing—with multiple parts, multiple plan types, and enrollment rules that carry real financial consequences if not followed correctly. United Allstar Insurance Advisors has helped hundreds of clients in the Spring and Houston area navigate Medicare with confidence, and we are here to help you do the same.
Below is a clear, straightforward overview of each part of Medicare. When you are ready to move from understanding to action, we are here to help you choose the plan combination that makes the most sense for your health needs, your doctors, and your budget.
Medicare Part A — Hospital Insurance
Part A covers inpatient hospital stays, skilled nursing facility care, home health care, and hospice care. For most people, Part A is premium-free at age 65 because you or your spouse paid Medicare taxes while working. However, Part A alone carries significant out-of-pocket exposure—including a high inpatient deductible and coverage limits on hospital and skilled nursing facility stays that can leave you with substantial bills. A Medicare Supplement plan can help cover what Part A does not pay.
Medicare Part B — Medical Insurance
Part B covers outpatient services — doctor and specialist visits, lab work, X-rays, MRIs, durable medical equipment, and outpatient hospital care. Part B requires a monthly premium, which is typically deducted from your Social Security benefit. After meeting the annual deductible, Medicare Part B pays 80% of approved services, leaving you responsible for the remaining 20% with no cap on your out-of-pocket exposure. A Medicare Supplement policy fills this gap, protecting you from potentially unlimited out-of-pocket costs.
Medicare Part C — Medicare Advantage
Part C, commonly known as Medicare Advantage, is an alternative to Original Medicare offered by private insurance companies approved by Medicare. These plans combine Part A and Part B coverage and often include prescription drug coverage and additional benefits such as dental, vision, and hearing. Medicare Advantage plans operate through HMO or PPO networks, meaning your choice of doctors and hospitals may be more limited. It is important to fully understand the trade-offs of a Medicare Advantage plan before enrolling. We can walk you through a side-by-side comparison so you can make the most informed decision possible.
Medicare Part D — Prescription Drug Coverage
Original Medicare does not include prescription drug coverage. Part D plans are stand-alone drug coverage plans offered by private insurance companies approved by Medicare. Premiums vary based on the drugs you take, and formularies—the list of covered drugs—change annually. During the Annual Enrollment Period (October 15 through December 7 each year), you can switch to the Part D plan that provides the best coverage and lowest out-of-pocket costs for your specific prescriptions. United Allstar Insurance Advisors can help you review your current prescriptions and identify the best plan each year.
Medicare Supplement Plans — Filling the Gaps
Medicare supplement insurance, also known as Medigap, is designed to cover the costs that Original Medicare leaves behind—including deductibles, copayments, and coinsurance. Because Medigap plans are federally standardized, the benefits of each plan letter are identical regardless of which insurance company offers them. The only differences are price and company financial strength — which is exactly where an experienced advisor adds real value.
Plan G is currently the most comprehensive plan available to new Medicare enrollees. It covers all Medicare-approved out-of-pocket costs except the Part B annual deductible, providing outstanding protection and predictable healthcare costs. We can compare Plan G rates from multiple carriers to find you the best value.
