1. Long-term care: Medicare does not cover long-term care, which includes care in a nursing home or assisted living facility.

2. Dental care: Routine dental care, such as cleanings, fillings, and extractions, are generally not covered by Medicare.

3. Hearing aids: Medicare does not cover the cost of hearing aids or exams to fit hearing aids.

4. Vision care: Routine eye exams and eyeglasses are generally not covered by Medicare, with some exceptions for specific medical conditions.

5. Cosmetic surgery: Medicare does not cover cosmetic surgery, which is performed solely to improve appearance.

6. Acupuncture: Medicare does not cover acupuncture, except for specific conditions such as chronic low back pain.

7. Prescription drugs: While Medicare does cover some prescription drugs, there are certain medications that are not covered, such as over-the-counter drugs and drugs for cosmetic purposes.
