EHR-Agnostic Architecture | MediChatApp Works Beyond One EHR

Live with Intergy today, built to follow you to Epic tomorrow

Many practices and health systems hesitate to add a new platform because “we might move EHRs in a few years.” MediChatApp is designed so that your operational rails for check-in, messaging, portal, automations, and virtual assistants do not have to be rebuilt from scratch every time your clinical system changes.

Today, MediChatApp is deeply aligned with Greenway Intergy – schedules, balances, recalls, encounters, and task flows are tied directly into Intergy. But under the hood, the system uses standards-first patterns that are compatible with future integrations to:

Epic
athenahealth
eClinicalWorks
NextGen Healthcare
Cerner / Oracle Health
MEDITECH
AdvancedMD and other ambulatory platforms

Any additional EHR integrations are always scoped, contracted, and implemented deliberately, but the foundation is already built to support them.

Design principles

Decouple workflows from any single EHR schema where possible.
Rely on standards (HL7 v2, FHIR, SFTP, APIs) instead of proprietary hacks.
Keep tenant, practice, and EHR configuration clearly separated.
Make it possible to support multiple EHRs across different tenants.
Allow migration paths (e.g., Intergy to Epic) without rewriting the whole platform.

Today: Intergy-Optimized Operational Layer

MediChatApp is live in production with Greenway Intergy, using patterns that are reusable with other EHRs.

Tight integration with Intergy data

Schedules and templates drive check-in, recalls, and outreach.
Balances and billing data feed payment prompts and follow-up workflows.
Demographics and insurance data underpin messaging and eligibility logic.
Tasks and queues are designed around Intergy concepts, not generic lists.

Clean boundaries between “EHR world” and “engagement world”

Intergy remains the system of record for clinical data.
MediChatApp owns engagement, automation, and staffing workflows.
Interfaces and APIs handle synchronization instead of fragile, tightly-coupled logic.
This separation is what makes future EHR options realistic instead of expensive rewrites.

Tomorrow: Ready to Sit Next to Epic and Other EHRs

Many MediChatApp conversations involve “we might move to Epic.” This is an expected part of the design.

Standards-first orientation

HL7 v2 for real-time feeds where appropriate.
FHIR (e.g., R4) for structured resources where supported.
Interface-engine compatibility (e.g., Mirth/NextGen Connect) for hospital IT teams.
SFTP and batch ingestion for legacy systems that are not API-forward.

Identity, tenants, and EHR configuration

Tenants know which EHR and integration profile they belong to.
Per-tenant configuration supports different EHRs across practices or regions.
SSO, MFA, and VPN patterns can be aligned with hospital identity providers.
Migration paths (e.g., Intergy to Epic) can be phased without losing MediChatApp rails.

Note: Any new EHR integration (Epic, athenahealth, eClinicalWorks, NextGen, Cerner/Oracle Health, MEDITECH, etc.) is subject to interface availability, security review, and a scoped implementation project with your IT team. The architecture is prepared for this; details are always done in partnership.

Where MediChatApp fits in a multi-EHR landscape

Large organizations rarely live in a single-EHR world. You might run Intergy in some locations, Epic in others, or maintain legacy platforms for specific service lines. The goal is not to replace your EHR – it is to create a consistent operational and patient engagement layer that can sit next to more than one clinical system.

MediChatApp is intentionally focused on:

Patient access, check-in, and messaging rails.
Automation and revenue-support workflows.
Virtual assistant and remote staffing operations.
Web, mobile, and portal experiences that can stand in front of multiple EHRs.

That focus is what keeps the platform EHR-agnostic over the long term, even as specific integrations start with Intergy and expand out.

Examples of supported and target EHRs

Live focus today

Greenway Intergy

Expansion targets

Epic (via standard hospital interfaces)
athenahealth
eClinicalWorks
NextGen Healthcare

Also considered

Cerner / Oracle Health, MEDITECH, AdvancedMD, and other ambulatory/hospital platforms, pending joint scoping and interface review.

This list is not a promise of pre-built integrations for every EHR. It reflects the platforms that MediChatApp is architected to support as your strategy evolves.

Planning an Epic migration or multi-EHR strategy?

If you are on Intergy today and thinking about Epic, athenahealth, or another enterprise EHR, you do not have to pause all progress on patient engagement and operations until the migration is done.

We can walk through a phased approach where MediChatApp:

Stabilizes and upgrades operations around Intergy now.
Is designed in a way that aligns with your target EHR architecture and security standards.
Becomes a reusable operations layer that can be extended to new systems as they come online.

This is especially important for access, check-in, messaging, and virtual assistants – the areas where operational continuity matters most during and after an EHR change.
