Which of the following may be extra benefits provided by MA-PD plans?

Medicare Advantage Prescription Drug (MA-PD) plans often offer a variety of extra benefits beyond the standard coverage provided by Medicare. These additional benefits can enhance the overall healthcare experience for enrollees. Vision care, dental services, and hearing aids are all recognized as common supplemental offerings that some MA-PD plans may include.

When a plan encompasses vision care, it typically covers services such as routine eye exams, glasses, or contact lenses. Similarly, dental services may involve preventive care like cleanings and check-ups, as well as more extensive treatments. Hearing aids may also be included, helping beneficiaries manage their hearing health.

By encompassing all these services, MA-PD plans aim to cater to the diverse needs of seniors, ultimately improving their access to necessary care and providing a more comprehensive healthcare package. Thus, the inclusion of all these potential extra benefits in MA-PD plans leads to the understanding that "all of the above" may indeed be offered, affirming the correct response.
