Which of the following cannot be used to qualify for Medicare Parts A and B?

Medicare Parts A and B eligibility is primarily based on specific criteria, and financial need is not one of them. To qualify for Medicare, most individuals must be at least 65 years old, which aligns with the age requirement. Additionally, individuals who are under 65 may qualify based on certain disabilities or specific medical conditions, further emphasizing that financial need does not play a role in determining eligibility.

Residential status is also not a barrier to qualification, as long as the individual meets the other criteria, including age or disability status. Work history is significant since it determines eligibility for premium-free Part A through sufficient work credits, typically earned through paying Medicare taxes while employed.

In summary, while factors such as age, residential status, and work history are integral to qualifying for Medicare Parts A and B, financial need does not influence eligibility for these programs.
