Medicare Part A primarily covers which of the following services?

Medicare Part A is primarily known for covering services related to inpatient care and specific types of long-term care. It primarily focuses on hospital stays, skilled nursing facility care, hospice care, and home health care, provided certain conditions are met. Therefore, the inclusion of long-term nursing care and inpatient care in the correct answer aligns with the fundamental purpose of Medicare Part A, which is to cover costs associated with care received during hospital admissions and necessary rehabilitation services after a hospital stay.

In contrast, outpatient rehabilitation is covered under Medicare Part B, which deals with outpatient services. Medical equipment and tests are also typically covered under Part B. While mammograms and colonoscopies are preventive services covered by Medicare, they fall under Part B as well. Thus, the focus of Medicare Part A remains on caring for patients who require more intensive medical supervision and support in a healthcare setting.
