Speech Generating Devices

Section: Durable Medical Equipment
Effective Date: July 01, 2018
Revised Date: May 14, 2018
Last Reviewed: January 14, 2019

Speech generating devices (SGDs) are speech aids that provide individuals with severe speech impairment the ability to meet their functional speaking needs. SGDs provide digitized speech as well as synthesized speech. However, SGDs do not include external speech processors that are part of a cochlear device/system used to capture and amplify sound. 

This policy is designed to address medical guidelines that are appropriate for the majority of individuals with a particular disease, illness, or condition. Each person's unique clinical circumstances may warrant individual consideration, based on review of applicable medical records. 

Policy Position

Coverage is subject to the specific terms of the member's benefit plan. 

SGDs may be considered medically necessary when ordered by the treating physician and ALL of the following criteria are met: 

  • A formal evaluation of the individual's cognitive and communication abilities have been performed by a Speech Language Pathologist (SLP). The findings of this evaluation must be documented as a formal written evaluation and forwarded to the individual's treating physician prior to the device being ordered. The written evaluation must include ALL of the following elements: 
    • Current communication impairment, including the type, severity, language skills, cognitive ability, and anticipated course of the impairment; and
    • An assessment of whether the individual's daily communication needs could be met using other natural modes of communication; and
    • A description of the functional communication goals expected to be achieved and treatment options; and
    • Rationale for selection of a specific device and any accessories; and
    • Demonstration that the individual possesses the cognitive and physical abilities to effectively use the selected device and any accessories to communicate; and
    • A treatment plan that includes a training schedule for the selected device; and
    • For a subsequent upgrade to a previously issued SGD, information regarding the functional benefit to the individual of the upgrade compared to the initially provided SGD; and
  • The individual's medical condition is one resulting in a severe expressive speech impairment; and
  • The individual's speaking needs cannot be met using natural communication methods; and
  • Other forms of treatment have been considered and ruled out; and
  • The individual's speech impairment will benefit from the device ordered. 

Accessories may be considered medically necessary if the coverage criteria for the base device are met and the medical necessity for each accessory is clearly documented in the formal written evaluation by the SLP. Speech pathology services pertaining to the individual's evaluation and training in use of these devices may also be considered medically necessary. 

If all the SGD coverage criteria are not met, the SGD will be denied as not medically necessary. When the SGD is not covered, accessories are also not covered. 

Requests for more than one SGD will be denied as not medically necessary. 

Laptop computers, desktop computers, personal digital assistant s (PDAs) or other devices that are not dedicated SGDs are not covered because they do not meet the definition of durable medical equipment (DME). This is a benefit denial. 

Communication aids that are not speech generating devices (e.g., communication boards) do not meet the definition of DME. Therefore, they are benefit denials. In addition, services related to non-speech generating devices are also not covered. 

Related Components and Accessories for SGDs

The SGD and its components may not be billed separately.

Speech generating software programs enabling a laptop computer, desktop computer or PDA to function as an SGD may be considered medically necessary as a SGD within the terms of this policy. Installation of the program or technical support is not separately reimbursable.

Separate billing should not be made for any software, interfaces, cables, adapters, interconnects, or switches necessary for the accessory to interface with the SGD.

Eye gaze or eye glance technology (e.g., DynaVox EyeMax System) may be considered medically necessary for an individual who meets the requirements for a SGD as documented on this policy, but has limited use of his or her extremities that renders the individual unable to control or sustain fine/gross body movements that would enable him or her to access an SGD using more conventional access methods such as switches or direct touch. The individual must have direct vision in one or both eyes, and for full control over the system, should have the ability to look up, down, left and right. The individual must also have adequate vision to view the screen, and must have the ability to focus on one spot for a brief period of time. Contraindications include, but may not be limited to, those individuals with the following conditions: continuous, uncontrolled head movement; nystagmus. It will be necessary for the provider to submit medical records and/or additional documentation to determine coverage for eye gaze access devices.
