What Mirth Connect is
Mirth Connect is a healthcare integration engine for routing, filtering, and transforming messages between health information systems. It supports bidirectional exchange and real-time synchronization, with tools for protocol conversion, advanced mapping, and channel mapping that users can create, test, and deploy. Listed formats include HL7 v2.x and v3.x, CSV and other delimited text, DICOM, EDI/X12, XML, JSON, NCPDP, and raw data. Transfer options include MLLP, TCP/IP, HTTP, files, databases, SFTP, FTP, SMB, WebDAV, email, JMS, SOAP, DICOM, and custom Java or JavaScript. The product page describes an enterprise API for EHR and practice management read/write across 800+ integration routes, plus a FHIR-enabled Patient Access API and SMART on FHIR support. Customers can self-host or use NextGen’s co-located US data centers or AWS environment. The customer operates the licensed engine and builds and supports interfaces in-house. Starting with version 4.6, the software uses a proprietary closed-source license, and upgrading to that version or later requires a purchased license. Pricing is on request; a complimentary license is available for active studies affiliated with a nonprofit institution.

Overview
Mirth Connect is an integration engine for moving and transforming messages between healthcare information systems. It is best suited to organizations with technical staff who can build and support interfaces in-house. Its breadth is a strength for complex exchanges, but customers take on operating the engine and version 4.6 onward requires a proprietary license.
Key features
The engine supports bidirectional routing, filtering, real-time synchronization, and workflow orchestration. It handles HL7 v2.x and v3.x, CSV and other delimited text, DICOM, EDI/X12, XML, JSON, NCPDP, and raw data. Transfer options include MLLP, TCP/IP, HTTP, files, databases, SFTP, FTP, SMB, WebDAV, email, DICOM, JMS, SOAP, and custom Java or JavaScript. This range is useful when partners use incompatible formats or transport methods; it also means interface work remains a customer responsibility.
Mapping tools cover protocol conversion, advanced mapping, and channel mapping that users can create, test, and deploy. The product page describes an enterprise API with read/write access across 800+ EHR and practice management integration routes, a FHIR-enabled Patient Access API, and SMART on FHIR support. NextGen says Mirth Connect is used in over 40 countries and supports exchange, import, and export of 340 million clinical documents annually. These are scale claims, not a substitute for assessing the interfaces an organization needs.
Customers can self-host or use NextGen’s co-located US data centers or AWS cloud environment. In each case, the licensed engine is maintained and operated by the customer, which should factor into staffing and support decisions. Installation supports Windows, Linux, and Mac OS X or macOS.
Pricing
Mirth Connect has paid licensing and a free option for a narrow audience. Starting with version 4.6, the software uses a closed-source proprietary license, and upgrading to version 4.6 or later requires purchasing a license.
- Mirth Connect for Research: free. A complimentary license is available for active studies affiliated with a non-profit institution, with eligibility limited to active non-profit research studies and subject to verification. It is the clearest fit for qualifying research, not general production use.
- Enterprise: Custom pricing, billed as a flat-fee annual license per server. Includes unlimited support cases per year, 50 channel analytics, SSL Manager, and Mirth Command Center access. It suits teams seeking those management tools without the higher analytics counts and extensions listed for Gold and Platinum.
- Gold: Custom pricing, billed as a flat-fee annual license per server. Includes unlimited support cases, 24x7 phone support, 100 channel analytics, and extensions. It adds round-the-clock phone support and extensions over Enterprise.
- Platinum: Custom pricing, billed as a flat-fee annual license per server. Includes unlimited support cases, 24x7 phone support, 200 channel analytics, and extensions. It is the tier for buyers needing the highest stated analytics allowance; no additional capabilities over Gold are described.
Extensions are available only with a Mirth Connect license and are not sold separately. The per-server annual structure and customer-run operations make staffing and deployment scope important parts of the cost decision.
Platforms
Mirth Connect is listed for API, Linux, macOS, self-hosted, web, and Windows use. Its installation guide names Windows, Linux, and Mac OS X or macOS as supported installer platforms. Hosting through NextGen’s US co-located data centers or AWS is also an option, while customers retain responsibility for operating the engine.
Who it's for
Mirth Connect fits healthcare organizations that need to connect disparate systems across varied clinical formats and protocols, and have the capacity to build and support interfaces internally. Its FHIR and API capabilities may matter to organizations working with EHR and practice management access routes. It is a weaker fit for buyers seeking a fully vendor-operated integration service or a general-purpose free license; the free plan is reserved for qualifying non-profit research studies.
Pros and cons
- Pro: Broad format and transport support can bridge systems with different exchange requirements.
- Pro: User-created, testable channel mappings and protocol conversion support tailored integration workflows.
- Pro: FHIR-enabled Patient Access API and SMART on FHIR support address modern healthcare API use cases.
- Con: Customers maintain the engine and build and support interfaces in-house, requiring internal technical capacity.
- Con: Version 4.6 and later require a paid proprietary license, and extensions are license-bound.
Alternatives
For organizations focused on billing workflows rather than system integration, compare Medical Billing Software and Revenue Cycle Management Software. Buyers seeking a broader integration-service category can also review Integration Platform as a Service Software.
- Office Ally Practice Mate is a better fit when free web or Windows practice billing tools are the priority: its Practice Mate plan is free and includes appointment scheduling, patient billing, configurable superbills, a patient ledger, and reports. Transactional fees may apply.
- Nextech is another paid option for buyers seeking software across iOS, macOS, web, and Windows.
- Oracle Health Revenue Cycle may suit buyers looking for a paid revenue-cycle product across Android, API, iOS, or web; pricing requires contacting Oracle, and products are purchased from Oracle Health.
- theBillingBridge is a free alternative listed for Android, API, and iOS.
- AKASA Platform is a paid alternative listed for API and web.
- CareCloud RCM offers paid custom solutions with sales contact for pricing and is listed for web.
- CareRight Billing and Claiming is another paid web option.
- Experian Health Revenue Cycle Management is a paid web option; pricing requires contacting Experian Health.
Verdict
Choose Mirth Connect if your organization needs broad healthcare interoperability and has the staff to own interface development and engine operations. Its extensive format and transport coverage is the main reason to choose it. Look elsewhere if you need vendor-operated integration or a broadly available free license rather than a paid, customer-run deployment.
Verdict
Mirth Connect covers a wide range of healthcare formats, transfer methods, and transformation workflows. Buyers should account for the licensing terms and the customer’s responsibility for operating the engine and supporting interfaces.
