Original Medicare explicitly excludes several common categories of healthcare and daily living needs. The primary categories not covered include: 1) Long-term or custodial nursing home care (assistance with activities of daily living over extended periods); 2) Routine dental care (cleanings, fillings, dentures); 3) Routine vision care (eye exams for glasses, contact lenses); 4) Routine hearing exams and hearing aids; and 5) Healthcare received outside of the United States (with rare emergency exceptions).
