Medicare Part A and Medicare Part B in the United States (US) are both part of Original Medicare but cover different types of healthcare services.

- Medicare Part B (Medical Insurance) covers outpatient medical services, including doctor visits, preventive care, lab tests, outpatient surgeries, durable medical equipment, and some home health care.

No, Medicare Part A in the United States (US) does not cover prescription drugs for outpatient use. However, it does cover medications administered during an inpatient hospital stay, skilled nursing facility care, or hospice care.
For routine prescription medications, beneficiaries must enroll in Medicare Part D or a Medicare Advantage (Part C) plan that includes drug coverage. Medicare Part D is a standalone prescription drug plan that helps cover the cost of medications at pharmacies.
Without Medicare Part D or another drug plan, beneficiaries will have to pay out-of-pocket for most prescriptions. Additionally, Medicare Part A does not cover over-the-counter medications, vitamins, or long-term medication use outside of a hospital setting.
To avoid high prescription costs, it is recommended that beneficiaries enroll in a Medicare Part D plan during their Initial Enrollment Period (IEP) to avoid late penalties and ensure continuous drug coverage.

Coverage Details:

15. Can I Have Medicare Part A Without Part B In The United States (US)?
Yes, you can enroll in Medicare Part A in the United States (US) without enrolling in Medicare Part B. However, this is usually only beneficial for individuals who have other health coverage, such as employer-based insurance.

For most beneficiaries, enrolling in both Medicare Part A and Part B provides comprehensive health coverage. However, if you have other credible insurance, you may choose to delay Part B and enroll later during a Special Enrollment Period (SEP) without penalty.
16. Does Medicare Part A Cover Emergency Room Visits In The United States (US)?
Medicare Part A in the United States (US) only covers emergency room (ER) visits if you are admitted to the hospital as an inpatient for at least two consecutive midnights. The ER visit is then considered part of your inpatient hospital stay.

If You Are Admitted:
- Medicare Part A covers hospital costs after you meet the deductible ($1,632 in 2024).

Since Medicare Part A does not cover ER visits alone, having Medicare Part B or a Medicare Advantage (Part C) plan is essential for full emergency care coverage.
