Final answer:
Individuals who are part of the Railroad Retirement Beneficiary are entitled to both Medicare and railroad retirement benefits. Medicare is a healthcare system for those over sixty-five, while Social Security provides income benefits to the elderly.
Step-by-step explanation:
Carrier jurisdiction for claims involving individuals who are part of the Railroad Retirement Beneficiary includes those who are entitled to both Medicare and railroad retirement benefits. Medicare is the public healthcare system that offers insurance primarily to people over sixty-five years old, as well as to some younger individuals with disabilities. In the context of retirement insurance, all workers contribute a percentage of their income into both Social Security and Medicare, providing income and health care benefits to the elderly.
These programs are collectively known as social insurance, given that they function like insurance, allowing individuals to make regular payments today in exchange for benefits they may receive in the event of aging or illness when old.
