Which of the following is an example of durable medical equipment covered under Medicare Part B?

The correct answer is hospital beds because they represent a category of durable medical equipment that is specifically designed for use in a home setting to provide necessary medical support to patients. Medicare Part B covers various types of durable medical equipment, which are defined as items that can withstand repeated use, are primarily for medical purposes, and are appropriate for use in the home.

Hospital beds are specifically meant to facilitate the care of patients who require assistance with mobility and positioning while recovering from illness or injury. They often come with features such as adjustable height and head/foot positioning, providing critical support to the patient and caregivers.

While wheelchairs also qualify as durable medical equipment and are covered under Medicare Part B, the selected answer emphasizes hospital beds particularly, which are tailored for at-home use in a medical context. Prescription glasses and hearing aids do not fall under durable medical equipment as they are classified into different categories regarding coverage and use; thus, they are not included in the durable medical equipment definition under Medicare Part B.
