NextGen exposes practice data through its own API, and it also ships NextGen Connect, the interface engine NextGen picked up when it acquired the Mirth Connect project, used to build HL7 interfaces and EDI connections for claims. Both are real, documented capabilities. Most practices never go past the default setup NextGen ships with, so we build the intake, billing, and referral automation on top of that API and interface layer that would otherwise sit unused.
The NextGen API gives outside systems a structured way to read and write practice data, appointments, patient demographics, billing records, without anyone touching the NextGen interface directly. It's the layer custom automation, like what we build, uses to move data in and out on a schedule instead of someone exporting a report by hand.
NextGen Connect is a separate, lower-level piece: an interface engine built for routing HL7 messages between NextGen and lab systems, hospitals, or other EHRs, plus EDI connections for insurance claims. Larger practices and health systems use it to keep clinical and billing data flowing between NextGen and whatever else they run.
NextGen also runs a developer program and an app marketplace, where third-party tools plug into NextGen through the same API rather than a one-off custom build. Whether a given automation needs a marketplace app or a purpose-built connection depends on how close an off-the-shelf tool gets to what your practice actually needs.
Knowing NextGen has an API is different from having someone build against it. Setting up a working HL7 interface or wiring an EDI connection through NextGen Connect takes someone who understands both the practice's workflow and NextGen's own data model, and that's not a skill set most front-office or billing teams have on staff.
The gap isn't that NextGen's integration tools are weak. It's that a practice usually finds out this layer exists only after someone's spent a month manually re-entering the same referral or claims data a connected system could have handled on its own.
If billing staff are exporting NextGen claims and payment data to reconcile against QuickBooks or another accounting tool by hand, we build the connection that keeps both sides current automatically through NextGen's API.
Where a practice is still relying on a fax or a manual upload to get lab or referral data into NextGen, we use NextGen Connect's HL7 layer to route that data in directly, so staff aren't the ones keying it in.
Tell us what it is and we'll look at whether NextGen's own API or Connect layer can carry it automatically instead.
Whatever's still getting typed in twice between NextGen and the rest of your practice's systems is worth a look, and NextGen is just one piece of a bigger picture. We build this same kind of connection for any tool a practice already runs, not only the ones with a documented API.
Let's talk →Yes. NextGen exposes a documented API that lets outside systems read and write practice data such as appointments, demographics, and billing records, which is the layer custom integration work uses to connect NextGen to the rest of a practice's systems.
NextGen Connect is NextGen's interface engine, originally the open-source Mirth Connect project that NextGen acquired, used for building HL7 message interfaces between NextGen and labs, hospitals, or other EHRs, along with EDI connections for insurance claims.
Yes, through NextGen Connect. HL7 handles clinical message exchange with outside systems, while EDI connections route claims and payer data for billing, both configured through the interface engine rather than the main NextGen application.
Yes. NextGen runs a developer program and a marketplace where third-party applications connect to NextGen through its API, giving practices an option between an off-the-shelf marketplace app and a custom-built integration depending on how specific the need is.
