Medicare Part B is a component of the United States Medicare program. It primarily covers outpatient care, including services from physicians and other healthcare providers. Unlike Medicare Part A, Part B involves a monthly premium and provides coverage for medically necessary services and some preventive measures. Beneficiaries must enroll and pay the associated premium to access these benefits.
Medicare Part B covers two main categories of services: medically necessary services and preventive services. Medically necessary services include diagnoses, treatments, and follow-ups for conditions. Preventive services cover screenings, vaccinations, and annual wellness visits to detect and prevent health issues.
Enrollment in Medicare Part B typically begins around a beneficiary's 65th birthday. There is a seven-month initial enrollment period that starts three months before the month an individual turns 65 and ends three months after. If beneficiaries miss this window, they can enroll during the annual general enrollment period, which may result in late enrollment penalties.
Beneficiaries of Medicare Part B must pay a monthly premium. The cost is dependent on income. Higher-income beneficiaries pay a larger percentage of the premium. There is also an annual deductible, and after this is met, 20% of most services' costs are covered by Part B.
Medicare Part A primarily covers hospital inpatient services, skilled nursing facility care, and some home health services without a monthly premium for those who qualify. In contrast, Part B covers outpatient and preventive services requiring a premium, which covers costs for medical services and supplies not included in Part A.
