EHR Integration
AI agents for ModMed
Caesar Health runs the administrative work around ModMed: the phone, the fax line, intake, scheduling, follow-up and the revenue-cycle work. Results are written back through ModMed’s own API, and EMA stays the system of record.

About ModMed
ModMed (Modernizing Medicine) is a specialty-focused EHR and practice-management platform, strong in dermatology, ophthalmology, orthopedics, and more.
ModMed’s EMA and gGastro systems are built around specialty workflows — dermatology, ophthalmology, orthopedics, plastics, and GI — where documentation and coding are highly specialized. Caesar Health is an official ModMed marketplace partner, so the agents slot into those specialty workflows rather than working around them.
Does Caesar write back into ModMed, or does my staff re-key it?
It writes back. Nothing lands in the chart without a person accepting it.
The note. ModMed built a supported path for this. Its API documentation describes sending transcribed or textual content into an unfinalized visit note or as a standalone chart note. It's a road ModMed paved, not a workaround.
Caesar posts the visit note as a FHIR Composition against the encounter, typed as a LOINC 11488-4 consult note in preliminary status. A firm administrator turns on "Enable Transcription Status" to allow it. If the provider marks the encounter held for transcription, the text lands in the visit note; otherwise it becomes a new chart note. Either way the physician reviews and edits before anything is incorporated.
Sections map to their LOINC codes, so the note arrives structured, not as one block:
| Section | LOINC |
|---|---|
| Chief complaint | 10154-3 |
| History of present illness | 10164-2 |
| Review of systems | 10187-3 |
| Physical findings | 29545-1 |
| Evaluation note | 51848-0 |
Documents. Generated PDFs, such as requisitions, summaries or an inbound fax matched to a patient, upload to the patient's chart through ModMed's Binary then DocumentReference sequence.
Scheduling. Slot search, booking, rescheduling, cancellation and confirmation run against ModMed's Appointment and Slot resources. The phone agent books into real availability, not a mirrored calendar.
What stays in EMA: ModMed's procedure and treatment-plan forms, the ones that drive CPT and ICD generation for billing. ModMed doesn't expose them through its API, so no third party can fill them. Your physicians keep completing them in EMA.
How the ModMed integration works
ModMed has two APIs, and the difference decides whether anything can write to your chart.
1. The Certified FHIR API. Free, self-service registration, FHIR R4, OAuth 2.0 with SMART App Launch. ModMed documents it as read and search only. Anything built only on it can look at your chart and can't put anything in it.
2. The EMA Proprietary API. This is the one with write access, and the one Caesar runs on. ModMed documents read, search, create and update on it. Access is partner-gated through ModMed's synapSYS program. Caesar Health is listed in the synapSYS Marketplace.
Auth. OAuth2 tokens against ModMed's token endpoint, with an API key issued for your practice and a firm URL prefix that identifies it on every call. You control the key and can revoke it.
Documentation. ModMed's developer portal is at portal.api.modmed.com. Certified FHIR base URLs for every practice are published, each on its own subdomain.
What the proprietary API exposes to Caesar, and what it doesn't:
| Capability | Read | Write | Notes |
|---|---|---|---|
| Patient | Yes | Yes | Search, create, update |
| Appointment and slot | Yes | Yes | Book, reschedule, cancel, confirm |
| Practitioner, location, appointment types and reasons | Yes | — | Reference data |
| Coverage | Yes | — | Insurance on file |
| DocumentReference | Yes | Yes | Via Binary upload first |
| Composition (visit note) | — | Yes | preliminary status |
| ServiceRequest (orders) | Yes | No | Orders can't be placed by API |
| Procedure | Yes | No | |
| Encounter | Yes | No | Caesar attaches to an existing encounter |
The three read-only rows are the boundary of any ModMed integration, ours included. A technical buyer finds them in week one of a pilot anyway.
More on the mechanics: how the EMR integration layer works.
ModMed ships ModMed Scribe 2.0. Caesar works around the visit.
ModMed Scribe 2.0 is ModMed's ambient documentation product, built into EMA. It listens to the visit and suggests note content and ICD-10 codes in near real time. Because it's inside the EHR, it reaches fields a third-party API can't.
So Caesar doesn't sell a competing scribe on ModMed. Its surface is the work around the visit:
- The call at 4:50 pm that nobody answered.
- The pathology result that arrived by fax and sat in a queue.
- The intake that should have happened before the patient sat down.
- The recall nobody made.
Keep EMA. Keep ModMed Scribe 2.0. 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. On ModMed it writes through the same Composition path. How Caesar compares to a scribe.
Where Klara fits
ModMed sells Klara as ModMed Patient Engagement. If you're on ModMed, patient messaging may already be in your stack.
Klara's published phone features move a caller into a text thread and transcribe voicemails into the patient conversation. Caesar's phone agent answers the call, holds the conversation, searches real ModMed availability and books the appointment. Practices running both keep staff messaging where it is and put Caesar on the line. Klara and Weave alternatives for ModMed.
What your staff stops doing
| Today | With Caesar |
|---|---|
| Answering the phone through lunch and after hours | The phone agent answers every call, 24/7 |
| Reading availability off the EMA schedule to a caller | Slot search runs against ModMed's live Slot data |
| Retyping a faxed pathology report into the chart | The Document Inbox reads, extracts, matches and files it |
| Calling patients back about a form they didn't fill | Intake is collected before the visit |
| Sending reminder and follow-up texts by hand | Reminders, no-show follow-up and balance reminders go out by SMS, on a per-clinic cadence with quiet hours |
| Typing the visit note into EMA from a transcript | The note posts as a Composition for review |
| Sorting which messages need a clinician | Anything ambiguous becomes a task with the context attached |

ModMed + Caesar Health — FAQ
Does Caesar Health replace ModMed?+
No. ModMed stays the EHR and the system of record. Caesar runs the administrative work around it and writes results back through ModMed's API. No migration, no data conversion.
Does the note write back into ModMed automatically?+
It posts automatically; it doesn't file automatically. Caesar sends the note as a FHIR Composition in preliminary status, and it appears in EMA for the physician to review and accept.
We already use ModMed Scribe 2.0. Why would we add Caesar?+
A scribe documents the visit. Caesar answers the phone, works inbound fax, runs intake, books appointments and handles follow-up, the work before and after the room. Keep ModMed Scribe; the two do different jobs.
How does Caesar connect to ModMed?+
Through ModMed's EMA Proprietary API, the one with write access, using an API key and firm URL prefix issued for your practice. Caesar reads and writes Patient, Appointment, Slot and DocumentReference, reads Coverage, and writes the visit note as a Composition. ModMed's free Certified FHIR API is read and search only.
Is Caesar Health a ModMed partner?+
Yes. Caesar Health is listed in ModMed's synapSYS Marketplace. Your practice's API key and firm prefix are issued against your practice and you can revoke them.
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.
