# E2510 Compliance Primer

**Purpose:** Internal reference — understand the rules before making design decisions

**Status:** Research (verify primary sources before citing to AbleNet)

## What Is E2510?

HCPCS E2510 covers **speech generating devices with synthesized speech, permitting multiple methods of message formulation and multiple methods of device access.** This is the high-end SGD billing code — the one that covers devices like AbleNet's QuickTalker Freestyle.

The device must:
- Generate speech output (synthesized or digitized)
- Support multiple message formulation methods (symbols, text, pre-stored phrases, word prediction)
- Support multiple access methods (direct touch, switch scanning, head tracking, eye gaze)

## The Two Rules That Matter

### Rule 1: The Device Must Be "Dedicated"

For Medicare/Medicaid billing under E2510, the SGD must be **dedicated** — configured so it is limited solely to speech generation at the time of delivery.

This means:
- The device boots into AAC software, not a general-purpose OS
- Non-speech apps (browser, games, media, calculator) are **disabled or removed**
- The user cannot access general tablet functions without an explicit unlock

**What "dedicated" does NOT mean (post-2015):**
- The hardware itself doesn't have to be purpose-built (iPads qualify via ACCI configurations)
- The device can physically be capable of running other software — it just can't be configured to do so at delivery
- Non-speech features can be unlocked post-delivery at the user's expense

### Rule 2: PDAC Coding Verification Is the Gate

The **PDAC (Pricing, Data Analysis, and Coding)** contractor — currently Palmetto GBA — reviews SGD products and issues coding verification letters. Without PDAC verification for E2510, claims get denied.

PDAC reviews:
- That the software generates speech
- That it meets the DME (durable medical equipment) definition
- That the funded configuration is dedicated to speech generation
- Product documentation and clinical applicability

**Practical implication:** QuickChat needs PDAC coding verification on the QuickTalker Freestyle to be fundable under E2510. This is a formal submission process through AbleNet.

## What's Allowed vs. What's Not

### On the funded (dedicated) configuration:

| Allowed | Not Allowed |
|---------|-------------|
| Speech output (synthesized/digitized) | Games or entertainment |
| Symbol-based communication | Web browser |
| Text-to-speech | Media player (music, video) |
| Visual scene displays | Calculator, calendar |
| Sentence templates and word prediction | Social media access |
| Color coding (Fitzgerald Key) | Educational content unrelated to speech |
| Visual/auditory feedback on symbol selection | Any feature that makes the device look like a general-purpose tablet |
| SLP configuration tools | |
| Data logging for clinical use | |

### The gray zone (where design decisions live):

| Feature | Risk Level | Reasoning |
|---------|-----------|-----------|
| Animations on symbol tap | **Low** | Feedback reinforcing speech output — every SGD has some visual feedback |
| Multisensory feedback (color + sound + haptic) | **Low** | Directly tied to speech generation and symbol learning |
| Celebration after sentence completion | **Medium** | Could be framed as reinforcement for communication attempts, but looks like gamification |
| Rewards system / points / streaks | **High** | Looks recreational. No competitor includes this on funded configs |
| Gamified sentence builder | **High** | "Game" framing is a red flag for PDAC review |
| AR word explorer | **Very High** | Looks like an educational/entertainment app, not an SGD |
| Music/sound exploration | **Very High** | Explicitly non-speech |

## How Funding Actually Works (the flow)

1. **SLP evaluates** the child and documents medical necessity
2. **Physician** provides a face-to-face encounter and prescription
3. **DME supplier** (AbleNet or reseller) submits claim with:
   - SLP evaluation report
   - Physician prescription
   - Product with PDAC coding verification
4. **Medicare/Medicaid** processes the claim (post-payment review, not prior auth)
5. **Audits** happen after the fact — if the device doesn't look dedicated, the claim can be denied or clawed back

**Common denial reasons:**
- Missing or incomplete SLP evaluation
- Insufficient documentation of speech impairment severity
- No face-to-face physician encounter documentation
- Device not on PDAC Product Classification List
- Device configured as non-dedicated at delivery

**Not a common denial reason:** "The AAC app had animations." The risk is about the overall device configuration, not individual UI elements within the speech software.

## The PRC-Saltillo Precedent

PRC-Saltillo (TouchChat, LAMP Words for Life) ships the most widely-funded AAC software. Their model:

1. **Funded config:** Clinically sterile. Communication grids only. No animations, no rewards, no non-speech features. Desktop, calculator, calendar, music — all disabled.
2. **Post-delivery unlock:** $15 fee unlocks an "integrated features pack" that adds non-speech capabilities.
3. **Everyone unlocks immediately.** The funded config is a checkpoint, not the user experience.

This is the industry standard. The funded config exists to pass PDAC review and survive audit. The actual user experience includes features that could never be on the funded config.

## What This Means for QuickChat

1. **QuickChat needs a dedicated (funded) configuration** that passes PDAC review — speech generation features only, no gamification, no rewards, no AR
2. **QuickChat also needs the full experience** with engagement features for the consumer/post-unlock version
3. **AbleNet knows this.** They ship other companies' apps on the Freestyle and manage the dedicated configuration. Their concern is likely "will your innovative features jeopardize the Freestyle's E2510 status?" — and the answer is "not if we architect it correctly"
4. **Some features are safe on the funded config** — multisensory feedback, Fitzgerald Key color coding, visual scene displays, speak-choose-speak conversation loop. These ARE the speech generating function
5. **Some features need to live behind a post-delivery unlock** — rewards, celebrations, gamified elements, AR exploration
