Medicare premiums are income-based; beneficiaries with higher retirement incomes are subject to the Income-Related Monthly Adjustment Amount (IRMAA), increasing their Part B and Part D costs.
Standard Medicare coverage does not extend outside the United States, meaning seniors traveling abroad for retirement typically require supplemental travel insurance.
Preventive services intended to promote longevity, such as flu shots, bone density measurements, and cancer screenings, are covered by Medicare Part B without a copayment.
