CMS Speech Generating Devices Coverage Policy Update (NCD 274): What Billing Teams Need to Know

CMS has modified its National Coverage Determination for speech generating devices under NCD 274, with an effective date of March 12, 2026. This policy governs Medicare coverage of SGDs as durable medical equipment for patients with severe speech impairments—and the distinctions between what Medicare will and won't pay for are sharper than many billing teams realize. If your practice or DME supplier bills for SGDs, this update is worth a thorough read before claims start hitting payers in 2026.

What CMS Covers Under NCD 274: Speech Generating Device Definition and Benefit Category

Under NCD 274, the Centers for Medicare & Medicaid Services classifies speech generating devices (SGDs) as durable medical equipment under §1861(n) of the Social Security Act. To qualify for coverage, a patient must have a severe speech impairment and a medical condition that warrants use of an SGD.

The policy defines SGDs as DME that provides an individual with a severe speech impairment the ability to meet his or her functional speaking needs. Critically, these devices must be used solely by the individual with the severe speech impairment—shared-use or multi-patient scenarios fall outside coverage.

CMS recognizes four methods of speech generation under this policy:

• Digitized audible/verbal speech output using prerecorded messages
• Synthesized speech output requiring physical contact with the device (direct selection techniques) and message formulation by spelling
• Synthesized speech output allowing multiple methods of message formulation and multiple methods of device access
• Software that allows a computer or other electronic device to generate audible/verbal speech

That fourth category—software-based SGDs—is worth flagging for billing teams. The policy confirms that software running on a computer or tablet can qualify as DME, but only if the device is primarily used for speech generation and is limited to use by the patient with a severe speech impairment. General-purpose computers and tablets are explicitly not considered DME because they are useful in the absence of illness or injury.

Covered Features Beyond Audible Speech: What's Included

NCD 274 extends Medicare coverage beyond purely audible speech output. The following features are covered as part of an SGD:

• Email, text, and phone message capability — allowing the patient to "speak" or communicate remotely
• Software update downloads from the manufacturer or supplier, covering updates to the device's covered features

These inclusions reflect how modern SGD technology works in practice. Patients with conditions like ALS, severe cerebral palsy, or post-stroke aphasia often rely on device-based communication for remote interactions with caregivers, family, and healthcare providers. CMS's recognition of these features as covered is significant—but the non-covered boundaries are equally important to understand.

CMS SGD Non-Covered Services: Where Claims Get Denied

This is where many billing errors occur. NCD 274 is explicit about what Medicare will not cover, and the list is detailed enough that billing teams need a formal internal checklist.

Non-covered under NCD 274:

• Internet or phone services — even if necessary to use the SGD's communication features. CMS's rationale: these services are not exclusive to medical use.
• Home modifications required to allow use of the SGD — same reasoning applies.
• Computing hardware or software not necessary for speech generation, email, text, or phone messaging, including:
  • Document creation and spreadsheet software
  • Games or music applications
  • Video communications or video conferencing
  • Any general computing function not directly tied to the patient's functional speaking communication needs

CMS makes clear that the cost of non-covered features is the beneficiary's financial responsibility. Suppliers are encouraged—though not required—to furnish beneficiaries with a voluntary Advance Beneficiary Notice (ABN) identifying these non-covered features and alerting patients to the associated costs.

For billing teams: if a device is being submitted for reimbursement and it includes any of these features, the claim should reflect only the covered portion. Submitting the full device cost without accounting for non-covered features creates compliance exposure.

MAC Jurisdiction Discretion: Why Your Location Matters

One of the most operationally significant provisions in NCD 274 is this: A/B MACs (Medicare Administrative Contractors) acting within their respective jurisdictions retain discretion to cover or not cover SGDs based on their individual reasonable and necessary determinations.

This means coverage is not uniform across the country. Your local MAC may apply coverage criteria that are more or less restrictive than what the NCD articulates. Before billing for an SGD, your team should confirm the current Local Coverage Determination (LCD) or coverage article in effect for your MAC jurisdiction.

This MAC-level variability is also relevant for prior authorization. While NCD 274 does not specify a prior auth requirement at the national level, individual MACs may impose one. Check your MAC's website or contact the provider relations line before assuming prior auth isn't needed.

Affected Codes

NCD 274 as published does not list specific CPT or HCPCS codes within the policy document. Billing teams should reference their MAC's applicable Local Coverage Determination and associated billing and coding articles for the HCPCS codes currently recognized for SGD claims in their jurisdiction. Common HCPCS code ranges for SGDs have historically fallen in the E2500–E2599 range, but confirm current codes with your MAC—do not rely on historical codes without verification.

No specific codes are listed in this policy document. Fabricating or assuming codes without MAC confirmation is a compliance risk.
