Original Medicare explicitly excludes several categories of healthcare services and everyday living assistance. The five major items and services not covered include: 1) Long-term custodial care (assistance with activities of daily living like bathing, dressing, and eating over extended periods); 2) Routine dental care (cleanings, fillings, tooth extractions, and dentures); 3) Routine vision care (eye exams for prescription eyeglasses and contact lenses); 4) Routine hearing exams and hearing aids; and 5) Healthcare received outside of the United States (barring rare, specific emergency exceptions near borders).
