Medicare Part B – Medical Insurance
Medicare Part B provides medical insurance coverage under Original Medicare. It primarily covers outpatient services, physician visits, preventive care, and medically necessary services not requiring inpatient hospital admission. Enrollment and cost-sharing requirements are established by federal regulation through the Centers for Medicare & Medicaid Services (CMS).
What Does Part B Cover?
Medicare Part B covers outpatient medical services, including physician visits, preventive screenings, mental health services, diagnostic testing, durable medical equipment, and certain home health services. Coverage applies when services are medically necessary or meet Medicare’s preventive care guidelines.
Physician and Outpatient Services
Part B generally covers services provided in outpatient settings such as physician offices, clinics, hospital outpatient departments, and other approved facilities. This includes evaluation and management visits, specialty care, and follow-up treatment services.
Preventive Services
Medicare Part B includes coverage for many preventive services, such as annual wellness visits, certain cancer screenings, cardiovascular screenings, and other preventive benefits defined by Medicare guidelines.
Mental Health Services
Part B provides coverage for outpatient mental health services, including diagnostic evaluations, individual therapy, group therapy, and certain psychological testing when medically necessary and provided by qualified professionals.
Durable Medical Equipment (DME)
Medicare Part B may cover medically necessary durable medical equipment such as walkers, wheelchairs, oxygen equipment, and other approved devices when prescribed by a qualified provider and obtained through a Medicare-approved supplier.
Part B Premiums and Cost Sharing
Enrollment in Part B typically requires payment of a monthly premium. Premium amounts may vary based on income. In addition to premiums, beneficiaries are generally responsible for an annual deductible and coinsurance for covered services, unless supplemental coverage is in place.
Late Enrollment Penalties
Individuals who delay enrollment in Part B without qualifying coverage may be subject to a late enrollment penalty. The penalty amount and duration are determined by federal rules and are generally based on the length of the enrollment delay.
