EHR Integration
AI agents for eClinicalWorks
Caesar Health runs the administrative work around eClinicalWorks: the phone, the fax line, intake, scheduling, follow-up and the revenue-cycle work. Results are written back into eCW, and eCW stays the system of record.

About eClinicalWorks
eClinicalWorks (eCW) is one of the largest cloud ambulatory EHRs, used across a broad range of specialties.
eClinicalWorks has one of the largest ambulatory install bases in the country, spanning solo practices to large multi-specialty groups. That breadth means a lot of repetitive front-office and revenue-cycle work — the exact surface Caesar Health’s agents take over while eCW stays the system of record.
Is there an AI scribe that integrates with eCW, and does it write back?
Two questions, two answers.
What eCW's API allows. eClinicalWorks publishes certified FHIR APIs, free to developers and customers, across two portals: fhir.eclinicalworks.com for provider-facing and bulk apps, and connect4.healow.com for patient-facing apps through healow. eCW labels its USCDI resource sets "Read APIs." There's no published endpoint that files a visit note into an eCW chart the way ModMed's Composition or athenahealth's note sections do.
How Caesar writes back. The phone, SMS and fax layer runs on Caesar's own infrastructure and needs nothing from eCW. For work inside the chart, Caesar's EMR Integration Layer uses its web agent: it signs in as a named eCW user and works the same screens a staff member would, from workflows recorded for your practice.
What that means in practice:
- It needs its own named eCW user, with permissions scoped to what it may touch.
- It's slower than an API call, and it holds a session.
- When eCW changes a screen, updating the recorded workflow is our job.
- Every action is logged on our side and attributable to that user on yours.
On ModMed and athenahealth, Caesar writes through the vendor's API, and those pages name the endpoints.
How the eClinicalWorks integration works
What eCW publishes. eClinicalWorks offers certified FHIR APIs to third-party developers and eCW customers at no cost, certified to §170.315(g)(10).
Auth is OAuth 2.0 with SMART App Launch. Provider apps authenticate against the eCW EHR login; patient apps against the healow login.
Two gates to plan around. eCW reviews and approves every registered app, and the practice then switches the APIs on inside the eCW application. Neither is hard; both take calendar time.
What Caesar runs on eCW:
| Capability | How it runs |
|---|---|
| Inbound and outbound calls, warm transfer to staff | Caesar's own telephony |
| SMS reminders and follow-up | Caesar's own messaging |
| Inbound and outbound fax | Caesar's own fax line |
| Tasks, review queue, audit trail | In Caesar |
| Patient search and create | Web agent |
| Open slots, booking, rescheduling, cancellation, confirmation | Web agent |
| Filing a document to the patient's chart | Web agent |
| Reading the patient's chart | Web agent |
Setup. A named eCW user for the agent with the right permissions, and a session to record which screens it operates. A web agent needs no eCW marketplace listing, because it's your own user account doing your own work.
More on the mechanics: how the EMR integration layer works.
eCW ships Sunoh.ai. Caesar works around the visit.
Sunoh.ai is the ambient AI scribe integrated with eClinicalWorks. It listens to the visit and produces the note, and it runs in eCW, eClinicalTouch on iPad and eClinicalMobile.
Sunoh isn't exclusive to eCW. Its own site lists athenahealth, Cerner, eClinicalWorks, Epic, ModMed, Practice Fusion and Tebra among the EHRs it works with, through a free EHR Sync install.
So a practice on eCW has a scribe choice already. Caesar's surface is the work around the visit:
- The calls that come in while everyone is in a room, and the ones after five.
- The faxed results and referrals that arrive as paper.
- The intake and insurance that should be done before the patient sits down.
- The follow-up and the recall nobody made.
Keep eCW. Keep Sunoh. Caesar still has a full day's work.
Caesar also includes ambient documentation for practices that want one system across phone, fax and the room: see the AI Scribe and clinical documentation. How Caesar compares to a scribe.
What your staff stops doing
| Today | With Caesar |
|---|---|
| Answering the phone through lunch and after hours | The phone agent answers every call, 24/7 |
| Taking messages that turn into callbacks | The agent handles the request on the call |
| Retyping faxed results and referrals | The Document Inbox reads, extracts, matches and files them |
| Chasing intake forms and insurance cards | Intake is collected before the visit |
| Sending reminders and follow-ups by hand | Reminders, no-show follow-up and balance reminders go out by SMS, on a per-clinic cadence with quiet hours |
| Sorting voicemails to find what needs a clinician | Anything ambiguous becomes a task with full context |
| Keying the same patient detail into three screens | Captured once on the call, carried through |
How Caesar Health connects to eClinicalWorks
eClinicalWorks is API-forward, so Caesar Health connects through its FHIR and API surface — reading patient, scheduling, and billing context and writing every result back. eClinicalWorks stays the system of record. No rip-and-replace, no migration — the agents run alongside the system your clinicians already use.
FHIR API
Modern, standards-based read/write where the EMR exposes FHIR.
HL7 v2 messaging
The interface standard most EMRs already speak for orders, results, and ADT.
Direct database
Secure direct access where APIs don’t reach the data.
Interface-level layer
For legacy or no-API systems — connects at the screen level, no vendor cooperation required.
Every Caesar Health agent, on eClinicalWorks
All 14 agents read from and write back to eClinicalWorks. Here’s what each one does inside your workflow, with the Revenue Cycle agent broken out by function.

Reads inbound faxes, classifies each one, and files it to the right chart in eClinicalWorks.
Triages patient and provider email, drafts replies, and logs the thread against the patient in eClinicalWorks.
Runs two-way patient texting — reminders, confirmations, and rescheduling — synced to the eClinicalWorks schedule.
Answers questions on your website and books visits straight into the eClinicalWorks schedule, 24/7.
Clinical
Patient Experience

eClinicalWorks + Caesar Health — FAQ
Does Caesar Health replace eClinicalWorks?+
No. eCW stays the EHR and the system of record. Caesar automates the administrative work around it. No migration, no data conversion.
Is there an AI scribe that integrates with eCW?+
Sunoh.ai is the scribe integrated with eClinicalWorks. Caesar runs the phone, fax, intake and follow-up around the visit and sits alongside whatever documents your encounters.
Does Caesar write back into eCW?+
Yes, through its web agent, which works eCW's screens as a named user. eCW's published FHIR APIs are read APIs, so no vendor files a note through them. A clinician reviews and signs in eCW either way.
We already use Sunoh.ai. Why would we add Caesar?+
Sunoh documents the visit. Caesar answers the phone, works fax, runs intake, books appointments and handles follow-up. Keep Sunoh; the two do different jobs.
How does Caesar connect to eClinicalWorks?+
Telephony, SMS and fax run on Caesar's own infrastructure and need nothing from eCW. Work inside the chart runs through the web agent, signed in as a named eCW user with scoped permissions.
Is it HIPAA compliant?+
Yes. Caesar signs a BAA. PHI is encrypted in transit and at rest with customer-managed keys, access is role-based with tenant isolation per organization and location, and access to PHI is logged. SOC 2 Type II is in progress.
