The Epic EHR Integration Cost Calculator is a free planning tool that estimates the engineering hours and budget needed to connect your software to Epic. It prices HL7 v2 interfaces, FHIR API integrations, SMART on FHIR apps, discovery and ongoing support at Taction’s blended rate of $50 per hour.
Taction Software built this calculator from the planning ranges behind 200+ healthcare projects delivered since 2013, so you can budget an Epic integration before speaking to any vendor. It turns the guidance in our Epic EHR integration guide into hours and dollars, and this page explains what the calculator estimates, what drives the numbers and how to read the results.
Our experts are ready to understand your business goals.
The calculator estimates the engineering effort Taction would plan for a typical Epic integration, shown first in hours and then in dollars at a blended $50 per hour across all roles. It separates one-time build work from recurring support, so finance teams can see capital and operating costs independently. It does not price Epic’s own program fees, your Epic analysts’ time, hosting or third-party licenses, because other parties set those. Every figure is a planning range, not a quote. The six components below make up each estimate the calculator returns.
Each HL7 v2 interface, such as an ADT feed, an orders stream or a results feed, is estimated at 80 to 400 hours. The range reflects message volume, custom segment handling and mapping depth. Our HL7 integration services page explains what each interface build includes.
A FHIR read integration that pulls patient, encounter, medication or observation resources from Epic is estimated at 120 to 480 hours. Write-back scopes sit toward the upper end because they need extra validation. Our FHIR API development service covers this work in more detail.
An embedded SMART on FHIR app that launches inside Epic clinician or patient workflows is estimated at 400 to 1,600 hours. Interface design, launch context and authorization handling drive most of that effort, which our SMART on FHIR app development team scopes with you.
Most estimates include a discovery sprint of 80 to 240 hours to confirm data requirements, the Epic access path, security design and the test plan. The sprint turns a calculator range into a fixed scope, and our healthcare software discovery workshop page describes the format.
Validation in Epic test environments, end-to-end scenario testing, clinical sign-off and go-live support are counted inside each interface and app estimate rather than hidden as extras. Choosing extended testing in the calculator moves those units toward the top of their ranges to reflect stricter acceptance.
After go-live, most Epic integrations need monitoring, error reprocessing and fixes when upgrades change behavior. The calculator adds an optional support retainer of 20 to 80 hours per month, shown apart from build cost, so recurring spend stays visible to finance and operations teams.
Two Epic integrations with the same interface count can differ in cost several times over, because effort depends on data direction, mapping complexity and how many environments must be validated. The calculator asks about each of these drivers and moves your estimate within the published range accordingly. Understanding them before you start helps you control scope, since several drivers are decisions you make rather than constraints Epic imposes. The six drivers below account for most of the difference between a lean Epic integration budget and an expensive one that surprises leadership.
Reading data from Epic is the simpler pattern. Writing clinical notes, orders or flowsheet values back adds validation, error handling and clinical review, which pushes estimates toward the top of each range. Our guide to writing SOAP notes back to Epic through FHIR shows why.
Clean mappings between standard fields cost less than custom transformations. Local code sets, free-text parsing and conversion between HL7 v2 and FHIR all add hours. Teams running an engine such as Mirth Connect can often reuse transformation logic across several Epic interfaces, lowering per-interface cost.
Admissions, orders, results, scheduling, medications and documents each carry their own message structures, workflows and edge cases. Every additional domain adds mapping, testing and monitoring effort, so the calculator counts domains separately instead of treating a multi-domain feed as one simple interface with one fixed cost.
Epic customers usually validate integrations in non-production environments before go-live, and each environment needs configuration, test data and sign-off. More environments and stricter acceptance criteria mean more hours, so the calculator lets you choose standard or extended testing rather than underestimating validation effort at the planning stage.
Any integration handling PHI needs encryption, access control and audit logging. Taction signs a business associate agreement before touching PHI and follows ISO 27001 certified processes. These controls are built into every estimate from the start, so the range already reflects HIPAA compliant development.
From version 4.6 in March 2025, NextGen moved Mirth Connect to a commercial license, and 4.5.2 was the last open-source release. Open Integration Engine is a fork of 4.5.2. Your engine choice changes license cost, which the calculator lists as a separate third-party item.
The calculator is only as accurate as the answers you give it, so it helps to gather a few facts before you begin. You need to know which Epic data you require, whether you will send data back, how many distinct interfaces you expect and who will support the integration after launch. If you are unsure about any answer, choose the more complex option, because it is easier to reduce a budget than to request more money mid-project. The six steps below walk through each input in the order the calculator presents it.
Start with the workflow you are supporting, such as referral intake, remote monitoring alerts or billing reconciliation. The use case decides which Epic data you need and how quickly you need it. Our Epic integration services page lists common use cases that map cleanly to calculator inputs.
Select HL7 v2, FHIR, SMART on FHIR or a combination. Many projects use HL7 v2 for real-time events and FHIR for on-demand queries. If you are unsure which standard fits, our HL7 versus FHIR comparison explains the trade-offs before you enter numbers.
Enter one interface for each distinct message stream or API workflow, such as admissions, lab results or scheduling. Bundling several domains into one entry understates effort. For population-level data, review FHIR bulk data export first, since it follows a different pattern from single-patient queries.
Mark each interface as read-only or bidirectional, then choose standard or complex mapping. Bidirectional flows, local code sets and heavy transformation move estimates into the upper half of each range. Being honest here matters more than any other input for producing a realistic budget range.
Choose standard or extended testing, then select a support level from light to heavy. Extended testing suits multi-facility rollouts and clinical write-back. Support is shown as a monthly figure, so you can compare retaining Taction with staffing the same work internally over time.
The calculator shows low and high hours and dollars, with support listed separately from build costs. Save the estimate for internal review, or send it to Taction to request a discovery sprint that converts the range into a fixed scope, timeline and delivery plan for approval.
Epic supports several integration standards, and most real projects combine more than one. The calculator prices each standard separately because they differ in build effort, testing approach and long-term maintenance. Choosing the right mix early prevents rework, since a pattern that suits real-time events may be the wrong choice for on-demand queries or population data. The six standards and tools below are the ones Epic integration projects rely on most often, and each maps to a specific calculator input so your estimate reflects the architecture you actually plan to build and support.
HL7 v2 remains the workhorse for real-time hospital events such as admissions, transfers, orders and results. It is reliable and widely supported inside Epic environments, but it needs careful mapping because local implementations vary. The calculator prices each v2 message stream as its own interface.
FHIR R4 APIs let applications query Epic for specific patient data on demand using modern web standards. They suit patient-facing apps, analytics and partner integrations. Our HL7 and FHIR integration services often combine FHIR queries with v2 feeds in one design that serves several workflows.
SMART on FHIR lets an app open inside Epic with the current patient and user context already set. It is the standard route for embedded clinical tools. Our comparison of EHR launch versus standalone SMART apps helps you choose the right launch model.
Bulk FHIR export moves data for whole patient populations in batches rather than one patient at a time. It suits analytics, quality reporting and value-based care programs. The calculator treats bulk export as a FHIR integration with complex mapping because of its volume and validation needs.
CDS Hooks lets an external service return decision support cards inside clinical workflows at defined moments, such as when an order is placed. It usually pairs with a SMART app for follow-up actions, and the calculator prices it within the SMART on FHIR app estimate.
An integration engine routes, transforms and monitors messages between Epic and other systems. Engine choice affects build speed, licensing, monitoring and support cost. Our healthcare integration engine comparison compares common options so you can select one confidently before finalizing your calculator estimate.
Every figure in the calculator comes from the same planning ranges Taction uses across its healthcare engineering work, priced at a blended $50 per hour for developers, integration engineers, QA specialists and project management. Using one rate keeps estimates transparent, because you can check any number by dividing it by fifty. The ranges below are planning figures, not quotes, and they stay consistent across our site. Epic program fees, your Epic analysts’ time, hosting, engine licenses and auditors are separate. For a wider view across vendors, see our HL7 and FHIR integration cost page.
A discovery sprint typically takes 80 to 240 hours. It confirms data requirements, the Epic access path, security design and the test plan, and it converts the calculator range into a fixed scope before build work begins. Most Epic programs start here to avoid costly rework later.
Each HL7 v2 interface typically takes 80 to 400 hours, depending on message volume, custom segments, mapping depth and testing cycles. Interfaces that reuse existing engine logic sit toward the lower end, while bidirectional or multi-facility feeds sit toward the upper end of the range.
A FHIR read integration typically takes 120 to 480 hours, covering authorization, resource queries, data mapping, error handling and testing. Write-back, bulk export and complex resource mapping push effort toward the higher end, especially where clinical review of written data is required.
An embedded SMART on FHIR app typically takes 400 to 1,600 hours, including user interface design, launch context, authorization, FHIR data access and clinical testing. Apps with write-back, CDS Hooks or complex workflows sit at the upper end of this planning range.
Ongoing support typically covers 20 to 80 hours per month for monitoring, error reprocessing, Epic upgrade testing and small changes. Organizations with several live interfaces often combine a retainer with quarterly reviews, keeping integrations stable as Epic versions and workflows change over time.
Combined programs reach MVP scale at 800 to 2,080 hours, or enterprise scale at 2,080 to 4,160 hours. A dedicated engineer costs $8,000 per month for 160 hours, or you can hire Epic integration developers as a three to five person team.
Taction has delivered 200+ healthcare projects since 2013, with integration engineering at the center of much of that work. We are an independent healthcare software development company, not an Epic partner or reseller, which means our estimates are not shaped by license sales and we work with whichever Epic access path suits your organization. Our teams operate from offices in Chicago, Austin, Sacramento and Cheyenne and serve healthcare clients across the United States. The six points below explain what stands behind each number the calculator produces and the delivery work that follows.
Every estimate shows hours first and dollars second, at one blended rate. Nothing is hidden inside a package price, and third-party fees are called out separately. You can compare our numbers line by line with another vendor’s proposal or with our wider EHR integration cost guide.
For Coronis Health, a global revenue cycle company, Taction built Mirth Connect HL7 channels across many client billing platforms, with validation, crosswalks and audit management that replaced manual transfers. The Coronis Health case study shows the delivery approach behind our interface estimates.
Xoomia needed one platform serving caregivers, home health agencies, clinics and government bodies, with Mirth Connect integration, role-based access and transaction-level audit logging. The Xoomia case study shows how we handle multi-party data flows like those in larger Epic integration programs.
Rhythm, a remote patient monitoring platform, needed bidirectional EHR integration working alongside enrollment, insurance verification, device logistics, triaged real-time alerts and billing guidance for providers. The Rhythm case study shows the two-way data work that our bidirectional calculator estimates are based on.
Taction is listed as a commercial support vendor on openintegrationengine.org, the home of the open-source fork of Mirth Connect 4.5.2. That gives Epic customers a supported engine option alongside commercial Mirth Connect, with licensing trade-offs explained before any build work starts.
We follow ISO 27001 certified processes and sign BAAs before any PHI work begins. We are not a law firm and do not give legal advice, and no official HIPAA certification exists, so we document safeguards instead of claiming a badge your compliance team cannot verify.
These are the questions healthcare IT leaders, product teams and digital health founders ask most often before relying on a calculator estimate for an Epic integration budget or board approval. They explain how the numbers relate to a formal quote, which costs sit outside the calculator and must be budgeted separately, and how this tool differs from other cost resources on our site. If your project involves a pattern the calculator does not cover, a short call with our integration engineers will give you a clearer, scoped answer for your specific environment.
The calculator gives a planning range based on Taction’s standard hour estimates, not a binding quote. Accuracy depends on your inputs. Most uncertainty comes from mapping complexity and testing cycles, which a discovery sprint of 80 to 240 hours resolves before any build work starts.
No. Epic program or connection fees, the time your Epic analysts spend, hosting, integration engine licenses and auditors are all separate costs. The calculator covers only Taction’s engineering hours at $50 per hour, so budget those third-party items independently and early in planning.
No. Taction is an independent healthcare software development company and is not an Epic partner or reseller. We build integrations using the access paths Epic makes available to your organization, and your team keeps its direct relationship with Epic throughout the project.
Use HL7 v2 when you need real-time hospital events such as admissions, orders and results. Use FHIR when you need on-demand queries, patient-facing apps or modern partner APIs. Many Epic programs use both, and the calculator prices each standard separately for that reason.
The ranges apply broadly, but the inputs are tuned for Epic. For other EHR platforms, our EHR and EMR integration services team produces estimates using the same $50 hourly rate and the same hour ranges for HL7 interfaces, FHIR integrations and SMART apps.
Our EHR integration calculator sits within our AI healthcare section and gives a general view of EHR integration effort. This calculator is specific to Epic and prices HL7 v2 interfaces, FHIR integrations and SMART on FHIR apps separately, using Epic-focused planning ranges.
