Information on Medicare Form 40B includes when to use it, instructions on how to complete it, and space to enter a person's Social Security number, name, address and signature, as noted by the Centers for Medicare and Medicaid Services. People who already have Medicare Part A but want to enroll in Part B should complete this form. Those who do not have Medicare Part A need to contact the Social Security Administration to enroll before enrolling in Part B.
Form 40B is available for download in both English and Spanish on the Centers for Medicare and Medicaid Services website. Applicants typically enroll in Part B during their initial enrollment period, which begins three months before their 65th birthday and ends three months after their 65th birthday, as noted on the form. Once an applicant completes this form, it should be returned to the local Social Security office.
Applicants should discuss with their physician whether Medicare Part B covers the services they need. There are two main types of services that Part B covers, states the U.S. Government site for Medicare. It includes medically necessary services, such as partial hospitalization costs, inpatient mental health services and ambulance services. Part B also covers preventive services, such as screenings and tests. Other services covered under Part B are clinical research, durable medical equipment and second opinions.
