Speech Generating Devices (CPB 0437, reviewed 2026-07-01)
Aetna covers speech generating devices (SGDs) as medically necessary durable medical equipment only when a speech-language pathologist (SLP) has completed a formal written evaluation before delivery, and the member has a permanent severe expressive speech disability, such as anarthria, aphasia, aphonia, apraxia or dysarthria, whose speaking needs cannot be met with natural communication methods. Only one SGD or speech generating software program at a time is considered medically necessary per member, and an SGD with multiple interfaces is generally considered not medically necessary. Desktop computers, laptop computers, tablets, smart phones and other devices that are not dedicated SGDs are not covered because they do not meet the definition of DME.
