To give you a solid foundation for the detailed analysis that follows, here’s an overview of how each EHR is built and who it serves.
athenahealth is not just an Electronic Health Records (EHR) company. It is primarily a Revenue Cycle Management (RCM) company that expanded into EHR.
This is because athenahealth was founded in 1997 by Jonathan Bush to manage a birthing center for billing and collections purposes. The original pain point back then was collecting payments and not managing patient records. Then, athenahealth launched its EHR module, athenaClinicals, in 2005. So that doctors could handle clinical notes, patient records, and diagnoses within the same software.
But even today:
- Its strongest product is athenaCollector, an RCM tool
- Its pricing model is collections-based, 4-8% of revenue
- Its biggest selling point is a 98.4% first-pass claim rate, that is a billing feature, not an EHR feature
- It wins in both Practice Management and Ambulatory EHR in KLAS, but still, when users leave athenahealth, it is mostly because of billing issues
What are those billing-related issues?
- The percent of collections model through which athenahealth charges you a percentage of your total earnings (often 4% to 8%) instead of a flat fee. So, as your clinic grows and you earn more, athena's fees increase with it
- Loss of control that comes from athena's ‘Service-Enabled’ model for some hospitals. Because in this model, their staff and the automated system handle billing. Hospitals’ main concern was that sometimes billing errors occur or claims get stuck, and the clinic does not have the control to deep dive into the system. Therefore, you have to depend on their customer support to deal with your money. Clinics that prefer in-house billing staff often switch away from athena for the same reason
- Recent reports and user reviews from 2025-2026 show that some clinics have complained that their revenue was slipping because athena software sometimes incorrectly rejects claims or slows down the process. Some providers have even said that due to billing issues they had difficulty making payroll, which is why they shifted to other platforms that offer more personalized service
Epic EMR is not just an EHR either, but an operating system for hospitals. Epic was founded in 1979 by Judy Faulkner as a database software specifically for storing patient records at the University of Wisconsin. Clinical workflows like EpicCare (its EHR component) were introduced later in the 1990s.
What Epic is today:
- Entire hospital operations run on it: pharmacy, lab, radiology, billing, scheduling, ICU, emergency, everything
- When a hospital implements Epic, it literally rebuilds its entire IT infrastructure around Epic
- Epic has its own app marketplace (App Orchard) where third-party developers build apps for Epic the same way developers build apps for iPhone
- MyChart has 195 million users and is so widespread that patients expect their doctor to be on Epic
- Epic built Care Everywhere, which allows Epic users to share data with each other nationwide, essentially a private health data network
Important Note: Epic is privately held and not publicly listed or private equity backed.
The positive side is that Epic's independent ownership gives hospitals confidence for long-term commitments and contracts. But this also means zero leverage on pricing.
Negotiating with Epic is almost impossible. A publicly listed company faces competitive pressure. But a privately owned company — if the owner decides there will be no negotiation, then there will be no negotiation. Epic's CEO said in October 2025:
"We say everybody pays the same price on the price list... The hardest negotiators, who were often not the nicest people, got the best deal, and that didn't feel right."
On top of that, hospitals do not leave Epic because the exit cost is too high. Switching costs for a mid-sized hospital can easily reach $20M–$50M.

Estimates suggest that the starting price pf athenahealth is around $140/provider. But athenahealth offers a unique pricing model based on the collections of the organization, which means that costs can vary depending on patient volume and revenue generation. This can help practices manage expenses more flexibly, especially during fluctuations in patient numbers.
Moreover, athenahealth emphasizes transparency in its pricing, claiming no hidden fees and no long-term contracts. Practices can opt out at any time and retain their data.
Epic, on the other hand, requires a significant upfront investment for its systems, which can be a substantial commitment for healthcare organizations. Though, as per some estimates, the starting price of Epic ranges from $100,000 for small practices. Costs often include software licensing fees, implementation costs, and ongoing maintenance.
Epic generally involves longer contracts and commitments, which might not provide the same level of flexibility that athenahealth offers. The implementation cost for Epic can range from $1200 to $500,000, depending on the complexity of the deployment and the size of the organization.

The most fundamental difference between athenahealth and Epic is the care setting they support. athenahealth was built exclusively for ambulatory care. Epic was built for both. For any hospital or health system that needs inpatient coverage, this table settles the comparison immediately:
Care Setting | athenahealth | Epic Module |
Outpatient/Ambulatory | Yes (athenaClinicals; visit documentation, e-prescribing, order entry) | Yes (EpicCare Ambulatory; same scope plus specialty-specific workflows) |
Inpatient/Hospital Admission | No | Yes (ClinDoc; nursing notes, physician documentation, medication administration, discharge planning) |
Emergency Department | No | Yes (Real-time bed tracking, triage scoring, ED-to-inpatient admission handoff) |
Surgery/Perioperative | No | Yes (OpTime; pre-op, intra-op, post-op documentation and OR scheduling) |
Radiology | No | Yes (Radiant; imaging orders, radiology reports, PACS integration) |
Pharmacy | No | Yes (Willow; medication ordering, dispensing, drug interaction checks at bedside) |
Home Health | Telehealth visits only | Yes (Dorothy; offline-capable home visit documentation) |
ICU/Critical Care | No | Yes (integrated with ClinDoc and predictive deterioration alerts) |
athenahealth users frequently praise the platform for its user-friendly and intuitive design, which simplifies communication between patients and providers. Many have reported a noticeable increase in collections, typically between 2% to 6%, along with a decrease in overhead costs. Users also appreciate the ease of managing appointments, although some have encountered difficulties when updating patient insurance information.
Epic has gained popularity across the healthcare industry, covering over 51.5% of acute multi-specialty hospital beds in the United States, according to KLAS. Users find Epic easy to use and commend its excellent billing features, which contribute to fewer denials from payers and insurance companies. However, the software's high cost can be a barrier for smaller organizations, and many users report a long implementation process that can be challenging to navigate.
Both athenahealth and Epic are powerful EMR systems designed to meet the needs of healthcare organizations, but they cater to different requirements. athenahealth stands out with a user-friendly solution that simplifies workflows for small to mid-sized ambulatory settings, while Epic is known for its comprehensive features purpose-built for larger healthcare networks.
Each practice has unique needs based on specialty, size, clinical and administrative workflows, and integration requirements. It's important to conduct a thorough assessment of these factors to determine which platform aligns best with your goals and can effectively support your team's workflow.
As Christine Sinsky, MD, points out in a recent article by the American Medical Association (AMA),
“Burdensome EHR systems are a leading contributing factor in the physician burnout crisis and demand urgent action.” Keeping this in mind, focus on finding an EMR that minimizes complexity and enhances efficiency to ultimately improve patient care and provider satisfaction.
