Which of the following is included in the services covered by Medicare Part A?

Skilled nursing facility care for 20 days is a service covered by Medicare Part A, which is designed to provide hospital insurance. This part of Medicare covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care services. Specifically, after a qualifying hospital stay of three days, Medicare Part A will generally cover skilled nursing facility care for up to 100 days, with the first 20 days fully covered. This allows beneficiaries to receive necessary rehabilitation and recovery services without incurring significant out-of-pocket costs during that initial period.

In contrast, prescription drug coverage falls under Medicare Part D, routine foot care is generally not covered unless there is a medical necessity related to a specific condition like diabetes, and acupuncture treatments are not reimbursed under Medicare unless they are for chronic low back pain in specific circumstances. Thus, the option regarding skilled nursing facility care aligns accurately with what Medicare Part A provides, making it the correct choice.
