A routine cancer screening or annual wellness visit might seem like something Medicare should cover completely, but some retirees discover unexpected charges after their appointments. The problem isn’t necessarily that Medicare has stopped covering preventive care. Instead, the difference between a screening, a diagnostic test, and an additional medical service can determine whether you receive a bill.
According to Medicare.gov, Medicare Part B continues to cover numerous preventive services in 2026, including certain cancer screenings, cardiovascular screenings, diabetes tests, and wellness visits. Many are available without a deductible or coinsurance when patients meet eligibility requirements and use providers who accept Medicare assignment.
