Learn About Medicare Part B Assistance Options

What Medicare Part B Covers and How It Works

Medicare Part B is one component of the Original Medicare program. It covers certain medical services and supplies that Part A (hospital insurance) does not include. Understanding what Part B covers helps people learn about their healthcare options under Medicare.

Part B primarily covers doctor visits and outpatient care. This includes visits to your primary care doctor, specialists, and other healthcare providers who accept Medicare. The program covers preventive services such as annual wellness visits, cancer screenings, and cardiovascular disease screenings at no cost to the beneficiary. Diagnostic tests like blood work and X-rays performed in outpatient settings are also covered.

Part B covers durable medical equipment (DME) such as wheelchairs, walkers, oxygen equipment, and diabetic supplies. It also covers mental health services, including therapy and psychiatric care. Ambulance services, outpatient surgery, and rehabilitation services are covered when medically necessary. Some people do not realize that Part B covers certain prescription drugs that are administered in clinical settings, such as chemotherapy or biologic medications given during office visits.

The program does have limitations and cost-sharing requirements. Beneficiaries typically pay a monthly premium for Part B coverage, along with an annual deductible. After meeting the deductible, most people pay 20 percent coinsurance for covered services while Medicare pays 80 percent. Some services may have different cost-sharing amounts.

It is important to note what Part B does not cover. Long-term care, nursing home care, custodial care, most dental work, routine eye exams, eyeglasses, and hearing aids are not covered. Cosmetic surgery and certain experimental treatments are excluded. Understanding these boundaries helps people plan for additional coverage options.

Practical takeaway: Review your own healthcare needs and compare them against what Part B covers. Make a list of doctors you currently see and services you use regularly. This information will help you understand whether Part B alone meets your coverage needs or whether supplemental coverage options may be worth exploring.

Understanding Part B Costs and Premium Payment Options

Medicare Part B involves several types of costs that beneficiaries should understand. The monthly premium is the most visible cost, but there are other expenses including deductibles, coinsurance, and copayments. As of 2024, the standard Part B premium is approximately $164.90 per month for individuals with higher incomes, though people with lower incomes may pay less.

The Part B annual deductible for 2024 is $240. This means a person must pay $240 out-of-pocket for covered services before Medicare begins paying its share. After the deductible is met, Medicare typically pays 80 percent of approved charges, and the beneficiary pays the remaining 20 percent. However, some preventive services such as cancer screenings and wellness visits are covered at 100 percent with no cost-sharing once you are enrolled in Part B.

Income-related monthly adjustment amounts (IRMAA) affect what higher-income beneficiaries pay for Part B. Medicare uses income information from two years prior to determine if someone falls into a higher income bracket. Individuals with modified adjusted gross income above certain thresholds pay higher premiums. For 2024, beneficiaries with income exceeding $97,000 (or $194,000 for married couples filing jointly) fall into higher premium brackets. These income thresholds can affect both Part B and Part D (prescription drug) premiums.

Part B premiums are usually deducted automatically from Social Security checks, though some beneficiaries pay directly to Medicare. People can request to pay premiums through bank accounts or other payment methods. It is important to understand that if you delay enrolling in Part B beyond your initial enrollment period, you may face a permanent penalty. The penalty equals 10 percent of the base premium for each full 12-month period that you were not enrolled.

Some people receive help with Part B costs through programs that may be available. These programs have different names in different states and may help pay premiums, deductibles, and coinsurance for people who meet income and asset requirements.

Practical takeaway: Calculate your estimated annual Part B costs by adding the annual premium amount to the deductible and estimating your likely coinsurance based on the medical services you use. Compare this to any out-of-pocket costs you currently pay. This gives you a realistic picture of Part B expenses versus your current healthcare spending.

Coverage Gaps and When Additional Coverage May Be Useful

Original Medicare (Part A and Part B) does not cover all healthcare expenses. Understanding these gaps helps people explore whether supplemental coverage options might reduce their out-of-pocket costs. One major coverage gap is the 20 percent coinsurance that beneficiaries pay for most Part B services. Someone receiving ongoing specialist care or regular treatments could face substantial coinsurance bills throughout the year.

Another significant coverage gap relates to prescription medications. Part B does not cover most outpatient prescription drugs—those medications taken at home. People who take multiple medications for chronic conditions like diabetes, heart disease, or arthritis need separate prescription drug coverage, typically through Medicare Part D. Without Part D coverage, people pay the full pharmacy price for these medications, which can be thousands of dollars annually depending on the drugs needed.

Part B also does not cover certain healthcare services that many people use regularly. Routine dental care, including cleanings and fillings, is not covered. Routine eye care and eyeglasses are excluded. Hearing aids and hearing exams are not covered by Original Medicare. For people who need these services regularly, the costs can accumulate. Annual dental care can cost $500 to $2,000 depending on treatment needs. Hearing aids average $2,000 to $6,000 per pair.

International care presents another coverage gap. Original Medicare generally does not pay for medical services received outside the United States. People who travel internationally or spend time in other countries may need supplemental travel coverage or expect to pay out-of-pocket for healthcare received abroad.

Cost-sharing can also become substantial for people with serious illnesses or chronic conditions requiring ongoing treatment. While Medicare Part B covers 80 percent of approved charges after the deductible, the 20 percent coinsurance can reach thousands of dollars in years when someone requires significant medical services. There is no annual maximum out-of-pocket limit in Original Medicare, meaning costs can be unlimited.

Practical takeaway: List the healthcare services you expect to use over the next year, including doctor visits, prescriptions, dental work, and vision care. Note which services are not covered by Part B. Estimate the costs you would pay out-of-pocket for uncovered services. This analysis reveals which coverage gaps affect you personally and may help determine whether supplemental or alternative coverage options warrant consideration.

Medicare Supplement Insurance and Medicare Advantage as Coverage Options

People with Original Medicare have options for addressing coverage gaps. Understanding the differences between these approaches helps with decision-making. Two main pathways exist: Medicare Supplement Insurance (also called Medigap) or Medicare Advantage plans.

Medicare Supplement Insurance policies are sold by private insurance companies and work alongside Original Medicare. These policies help pay some of the costs that Original Medicare does not cover, such as coinsurance, copayments, and deductibles. There are standardized Medigap plans identified by letters (Plan A, Plan B, Plan C, and so on). Each lettered plan offers the same benefits regardless of which insurance company sells it, though premiums vary by company and location. Some Medigap plans cover foreign travel, which Original Medicare does not. Others may offer additional benefits such as coverage for preventive care not included in Medicare. Medigap plans do not cover prescription drugs, so people using Medigap typically also enroll in Medicare Part D.

Medicare Advantage plans, sometimes called Part C, are an alternative to Original Medicare. These are managed care plans offered by private insurance companies that must cover all Part A and Part B services. Many Medicare Advantage plans include prescription drug coverage (Part D) built into the plan. However, Medicare Advantage typically has a different structure than Original Medicare. Instead of the 20 percent coinsurance model, Advantage plans often use copayments for specific services. These plans usually have network restrictions, meaning beneficiaries must use doctors and hospitals within the plan's network, except in emergencies.

The choice between Medigap and Medicare Advantage depends on individual circumstances. People who prefer maintaining relationships with specific doctors may prefer Original Medicare plus Medigap, since Medigap works with any
