Retirees face high healthcare costs beyond doctor visits, including dental, vision, hearing, and prescriptions, often not covered by Original Medicare. Medicare Advantage plans in 2027 increasingly offer bundled benefits like dental, vision, hearing, and drug coverage, but vary in premiums, provider networks, and formularies. Comparing plans carefully, considering out-of-pocket costs and provider access, is crucial. Medicare Supplement plans offer broader provider flexibility but usually lack bundled drug and dental coverage. Annual plan reviews help avoid unexpected expenses.
