# AI Voice Agent + DrChrono / Athenahealth: Patient Scheduling Without Front Desk

> DrChrono and Athenahealth both expose schedule, demographics, and appointment APIs. We walk through HIPAA-aware integration patterns for a CallSphere healthcare voice agent.

> The two cloud EHRs with the friendliest APIs for AI integration in 2026 are DrChrono and Athenahealth. Both expose patient demographics, schedule, and appointment write endpoints. CallSphere's healthcare deployment ships pre-built tools for both.

CallSphere reference architecture

A patient calls Monday morning. CallSphere voice agent identifies them by phone in DrChrono, confirms DOB for HIPAA, fetches the next available slot with their preferred provider, books the appointment, sends an intake form via SMS, and confirms insurance is on file. Total time 90 seconds. The medical assistant who used to do this can now triage clinical messages instead.

## How the EHR APIs expose it

**DrChrono** at `https://app.drchrono.com/api`: `GET /patients/?phone_number=...` for lookup, `POST /patients/` for create, `GET /appointments/?date=...&doctor=...` for schedule, `POST /appointments/` for booking, `PATCH /appointments/{id}/` for reschedule. OAuth 2.0 with scopes `patients`, `patients:summary`, `calendar`. Webhooks fire on `APPOINTMENT_CREATED`, `APPOINTMENT_MODIFIED`.

**Athenahealth** at `https://api.athenahealth.com/v1/{practiceid}`: `GET /patients` with `firstname`, `lastname`, `dob` for demographic match, `POST /patients` for create, `GET /appointments/open` for slot search by department and provider, `PUT /appointments/{appointmentid}` for booking (Athenahealth uses PUT to claim a pre-existing open slot rather than POST a new one), and `PUT /appointments/{appointmentid}/cancel` to cancel.

Auth: OAuth 2.0 with Athenahealth-specific token endpoint. Required Practice ID in path.

Both are HIPAA-eligible with BAA. CallSphere maintains BAAs with our subprocessors and runs healthcare workloads in segregated VPC tenancy.

## How CallSphere implements it

CallSphere's Healthcare vertical ships 14 tools (`lookup_patient`, `create_new_patient`, `get_available_slots`, `schedule_appointment`, `reschedule_appointment`, `cancel_appointment`, `verify_insurance`, `send_intake_link`, `add_clinical_note`, `request_callback`, `escalate_to_clinician`, `triage_symptom`, `book_lab`, `request_refill`). The same 14 wrap DrChrono, Athena, eClinicalWorks, and Practice Fusion via a thin adapter. The voice agent never sees the EHR brand.

CallSphere runs 37 specialist agents across 6 verticals with 90+ tools and 115+ DB tables. Pricing $149 / $499 / $1499 with a [14-day trial](/trial) and a [22% affiliate program](/affiliate). [Healthcare vertical](/industries/healthcare).

## Build steps

1. Sign a BAA with the EHR vendor and confirm your CallSphere tenant is provisioned in HIPAA-segregated capacity.
2. Register your OAuth app. For DrChrono, request scopes `patients` and `calendar`. For Athena, request department-scoped access.
3. Implement `lookup_patient` with two-factor verification: phone match + DOB confirmation. Never confirm match by phone alone.
4. Implement `get_available_slots`. Filter by provider, location, visit type, and patient insurance acceptance.
5. Implement booking. For DrChrono use `POST /appointments/`. For Athena use `PUT /appointments/{id}` against an open slot ID returned by `appointments/open`.
6. Capture the call recording in HIPAA-eligible storage; do not include PHI in non-eligible LLM logs. CallSphere redacts before logging.
7. Send post-booking SMS via a HIPAA-eligible SMS vendor with a generic confirmation ("Your appointment is booked. View details: ...").
8. Subscribe to webhook `APPOINTMENT_MODIFIED` so out-of-band schedule changes propagate.

## Code snippet

```typescript
// Book an Athenahealth appointment by claiming an open slot
const booking = await fetch(
  `https://api.athenahealth.com/v1/${practiceId}/appointments/${appointmentId}`,
  {
    method: "PUT",
    headers: {
      Authorization: `Bearer ${athenaToken}`,
      "Content-Type": "application/x-www-form-urlencoded",
    },
    body: new URLSearchParams({
      patientid: matchedPatient.patientid,
      appointmenttypeid: visitTypeId,
      bookingnote: "Booked by CallSphere voice agent",
    }),
  }
);
```

## FAQ

**Is this HIPAA-compliant?** Yes when both vendors have BAAs and the LLM provider is HIPAA-eligible. CallSphere uses HIPAA-BAA models and redacts PHI from non-eligible logs.

**How do you handle DOB confirmation?** Voice agent asks; speech-to-text outputs are matched against EHR DOB; mismatch routes to a human. We never confirm a patient by phone alone.

**Does this work on FHIR?** Yes. Both DrChrono and Athena expose FHIR endpoints; CallSphere supports them as an alternate adapter behind the same 14-tool interface.

**What about Epic and Cerner?** They expose FHIR endpoints with patient context and SMART-on-FHIR auth. Different scope review process; CallSphere supports both for enterprise deployments.

**How do I get started?** [Start a trial](/trial), pick Healthcare, and connect your EHR in Settings. See the [healthcare vertical page](/industries/healthcare).
