TL;DR: The Centers for Medicare & Medicaid Services modified NCD 274, the national coverage determination governing speech generating devices under the durable medical equipment benefit, effective January 9, 2026. Here's what billing teams need to know before submitting claims.
This update to the CMS speech generating device coverage policy reinforces the boundaries of what Medicare will and won't pay for under §1861(n) of the Social Security Act. The policy does not list specific HCPCS codes in the current documentation — but the coverage criteria, exclusions, and MAC-level discretion built into NCD 274 Medicare directly shape how claims get processed and whether you see reimbursement or a claim denial.

CMS Speech Generating Device Coverage Criteria and Medical Necessity Requirements 2026
The coverage policy under NCD 274 is narrow by design. CMS covers speech generating devices only for patients with a severe speech impairment who have a medical condition that warrants the device. Both conditions must be present. One without the other doesn't qualify.
CMS defines speech generating devices as durable medical equipment that gives patients with severe speech impairment the ability to meet their functional speaking needs. The device must be used solely by the qualifying individual. It can't be shared or used for general-purpose computing.
Four output methods qualify under the policy:
| # | Covered Indication |
|---|---|
| 1 | Digitized audible or verbal speech using prerecorded messages |
| 2 | Synthesized speech requiring message formulation by spelling with direct physical contact access |
| 3 | Synthesized speech allowing multiple methods of message formulation and multiple access methods |
| 4 | Software that allows a computer or electronic device to generate audible or verbal speech |
That fourth category matters. CMS explicitly covers software-based speech generation — which means some tablet or computer-based AAC apps can qualify as durable medical equipment if they meet the other criteria. However, the device itself still needs to be primarily used to generate speech for a patient with a severe speech impairment.
The "Dedicated Device" Distinction
This is where speech generating device billing gets complicated. CMS does not require the device to be dedicated solely to audible speech output. A device can generate email, text, or phone messages and still qualify as DME — because those functions help the patient "speak" remotely.
But general computing? Not covered. If the device also runs spreadsheets, plays games, plays music, or supports video conferencing, those features fall outside §1861(n). That's the hard line in this coverage policy.
Computers and tablets are generally not considered DME because they're useful to a healthy person. The burden of medical necessity falls on showing that the device serves the patient's functional communication needs — not that it also happens to generate speech.
Prior authorization requirements for speech generating devices are determined at the MAC level. Check with your Medicare Administrative Contractor before submitting claims, especially for high-cost devices or software-based solutions.
CMS Speech Generating Device Exclusions and Non-Covered Indications
CMS is explicit about what Medicare won't pay for under NCD 274. Knowing these exclusions prevents denials before they happen.
Internet and phone services are not covered. Even if the patient needs internet access to use their speech generating device, Medicare won't pay for that service. The rationale: those services could be used on standard phones or personal computers, so they're not exclusively medical.
Home modifications are not covered. If a patient needs electrical upgrades, wiring changes, or any physical modification to their home to use the device, that cost falls on the beneficiary. There's no pathway to get those costs covered under the DME benefit.
Non-speech computing features are not covered. This is the broadest exclusion and the one most likely to generate billing disputes. CMS specifically calls out:
| # | Excluded Procedure |
|---|---|
| 1 | Document and spreadsheet creation software |
| 2 | Game software |
| 3 | Music playback |
| 4 | Video communications and conferencing |
| 5 | Any computing function not directly tied to speech communication, email, text, or phone messages |
The policy language is clear: these features don't fall within the scope of §1861(n). The cost is the beneficiary's responsibility.
Suppliers must notify beneficiaries. CMS encourages — though doesn't mandate — that suppliers furnish a voluntary Advance Beneficiary Notice (ABN) or similar notice to alert the beneficiary that non-covered features are their financial responsibility. If your team supplies SGDs, make sure your ABN process covers this. A claim denial on non-covered device features that the patient wasn't warned about creates compliance exposure you don't want.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Severe speech impairment with qualifying medical condition | Covered | Per MAC LCD | Device must be used solely by the qualifying patient; all four output methods qualify |
| Digitized speech output (prerecorded messages) | Covered | Per MAC LCD | Must serve functional speaking needs of the patient |
| Synthesized speech via spelling / direct selection | Covered | Per MAC LCD | Physical contact with device required for this method |
| Synthesized speech with multiple message and access methods | Covered | Per MAC LCD | Most feature-rich method; still must be primary purpose of device |
| Software-based speech generation on computer or tablet | Covered | Per MAC LCD | Device not required to be dedicated; must be primarily for speech generation |
| Email, text, phone message generation | Covered | Per MAC LCD | Covered as an extension of functional speaking/remote communication needs |
| Internet or phone service fees | Not Covered | N/A | Could be used for non-medical devices; beneficiary responsibility |
| Home modification to enable device use | Not Covered | N/A | Beneficiary responsibility |
| Non-speech computing features (games, music, spreadsheets, video calls) | Not Covered | N/A | Outside scope of §1861(n); suppliers should issue ABN |

CMS Speech Generating Device Billing Guidelines and Action Items 2026
The effective date of January 9, 2026 is your line in the sand. Here's what to do before and after it.
| # | Action Item |
|---|---|
| 1 | Contact your A/B MAC now. The NCD grants Medicare Administrative Contractors discretion to cover or not cover speech generating devices based on their own reasonable and necessary determinations. Your MAC's local coverage determination governs your region. Don't assume NCD 274 alone is sufficient — pull your MAC's current LCD and verify alignment with your billing practices. |
| 2 | Audit claims for non-covered features. If your organization supplies SGDs or bills for them, review whether any current claims include charges for internet services, phone services, home modifications, or non-speech computing features. Those charges won't survive audit. Remove them before submission. |
| 3 | Standardize your ABN process for non-covered features. CMS encourages suppliers to issue Advance Beneficiary Notices for device features that fall outside §1861(n). Make this part of your standard intake process. Document the ABN in the patient record. |
| 4 | Verify medical necessity documentation at intake. Every claim requires evidence of a severe speech impairment and a qualifying medical condition. Confirm your intake workflow captures both. Missing documentation on either criterion is a straight path to a claim denial. |
| 5 | Check software-based SGD claims carefully. The policy covers software that runs on computers or tablets — but only when the device is primarily used for speech generation by a qualifying patient. If a patient is using a general-purpose tablet with AAC software, the burden of proof is higher. Make sure your documentation addresses the "primary purpose" standard and the "used solely by the patient" requirement. |
| 6 | Flag dual-use device situations. If a device has significant non-speech computing capability, split out the costs if possible. The speech-generation component may be coverable; the general computing hardware or software is not. Talk to your compliance officer before billing for high-cost devices with substantial non-covered features — the line between covered and non-covered components can get blurry fast. |
| 7 | Watch for MAC policy updates post-January 9. This NCD was last reviewed in July 2015 before this update. After a gap that long, MACs may issue updated LCDs to align with the modified NCD. Subscribe to your MAC's policy update feed and check for local coverage determination changes through spring 2026. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Speech Generating Devices Under NCD 274
The policy document for NCD 274 does not list specific CPT, HCPCS, or ICD-10 codes. This is important — it means speech generating device billing guidelines and applicable codes are determined at the MAC level through local coverage determinations, not at the national level through this NCD.
Contact your A/B MAC for the specific HCPCS codes they require when billing for speech generating devices. MAC LCDs typically include HCPCS E-codes specific to SGD device types and output methods. Submitting claims without verifying your MAC's required codes is one of the fastest ways to generate preventable denials.
Your MAC's LCD will also specify:
- Required diagnosis codes to support medical necessity
- Documentation requirements for the treating physician or speech-language pathologist
- Any prior authorization requirements specific to your region
If you're not sure where to start, your compliance officer or billing consultant can help you pull the current LCD from your jurisdiction before the effective date.
