Feature Comparison

The following table compares the core functionalities that matter most to medical practices in 2026.

Feature / Capability	Kareo (Tebra)	Athenahealth
EHR Core	Web‑based, specialty‑templated charts, e‑prescribing (including EPCS), advanced charting, voice dictation (via integration). Good for family medicine, pediatrics, internal medicine.	Full‑featured, cloud‑native EHR with a unified patient record. Strong specialty templates, mobile app, clinical decision support, and a robust patient portal.
Practice Management	Scheduling, appointment reminders (text/email), patient check‑in, eligibility verification, and basic reporting. Serves small practices well.	Enterprise‑grade scheduling, wait‑list management, automated patient reminders, self‑scheduling (optional), and detailed analytics dashboards.
Revenue Cycle Management	Integrated billing with claim scrubbing, ERA/EFT, payment posting, denial management, and patient statements. Kareo also offers a separate clearinghouse.	End‑to‑end RCM with AI‑driven claim editing, proactive payer performance monitoring, and a dedicated billing team (full service at higher tiers). Claims often clear faster due to Athena’s network.
Patient Portal	Kareo Patient Portal: secure messaging, online bill pay, appointment requests, and form fills. Mobile app available.	AthenaCommunicator: patient engagement platform with two‑way messaging, appointment reminders, bill pay, and telehealth integration. More customizable.
Telehealth	Integrated via Tebra Telehealth (powered by Updox). Simple, reliable for solo providers. Supports video visits and virtual check‑ins.	Built‑in telehealth module (AthenaTelehealth) with multi‑platform support (desktop, mobile). Handles group visits and integrates with the patient portal.
Interoperability / Network	Direct messaging, eFax, some lab interfaces (Quest, LabCorp). API available for custom integrations. Not as strong on care coordination.	AthenaNet® – a massive proprietary network connecting thousands of providers, hospitals, labs, pharmacies, and HIEs. Supports FHIR, CCD exchange, and Carequality.
Reporting & Analytics	Standard operating reports, MACRA/MIPS measures, and basic financial dashboards. Needs third‑party BI for deeper analysis.	Comprehensive analytics suite: clinical, financial, operational – including MIPS, PQRS, payer contract modeling, and population health tools.
Compliance & Security	HIPAA compliant, SOC 2 certified, 99.9% uptime SLA. ONC certified 2015 Edition.	HIPAA, HITRUST, SOC 2, and ONC certified. Robust audit trails and disaster recovery. Enterprise‑level security out of the box.

Pricing

Pricing structures differ significantly between the two platforms, reflecting their target audiences.

Kareo (Tebra) Pricing

• EHR standalone: Starts around $300 per provider per month.
• Practice Management: Approximately $200 per provider per month.
• Combined EHR + PM + Billing: Roughly $500–$600 per provider per month (all‑inclusive).
• Patient engagement / telehealth: Additional $50–$100/month for enhanced portal and video visits.
• Set‑up fee: $500–$1,000 one‑time (often waived during promotions).
• Contract term: Month‑to‑month or annual options available.

Kareo does not take a percentage of collections – you pay a flat fee. This can be very cost‑predictable for small practices with lower volumes.

Athenahealth Pricing

• AthenaClinicals (EHR) + AthenaCollector (RCM): Typically priced as a percentage of monthly collections – often 3% to 7% depending on practice size, specialty, and service level.
• For a small practice (2–5 providers), the percentage usually runs 5%–6% of net collections. For a 10‑provider practice it may drop to 4%–5%.
• Alternatively, per‑provider‑per‑month pricing is available for EHR‑only (around $400–$500/provider/month), but most clients use the full RCM model.
• Implementation fee: Varies widely – $5,000 to $30,000+ depending on scope and data migration.
• Contract: Typically 3‑year commitments with annual renewals.

Athenahealth’s percentage‑based model can be more expensive for high‑collection specialties (surgery, cardiology) but aligns incentives with revenue optimization.

Ease of Use

Kareo: 85/100

Kareo is widely praised for its intuitive, modern interface that requires minimal training. The layout is clean, with a left‑hand navigation bar and straightforward workflows. New users can start documenting patient visits within a few hours. The learning curve is low, especially for providers accustomed to paper‑based or less complex systems. Kareo’s mobile app (available for iOS and Android) is functional for scheduling and reviewing charts, though some users report it lags behind the web version. The system also includes a “Quick Start” wizard and on‑demand training videos. Overall, Kareo is one of the easiest EHR/PM combinations to adopt for independent practices.

Athenahealth: 78/100

Athenahealth offers a powerful but more complex interface. While the user experience has improved significantly over the years, there is still a steeper learning curve due to the sheer number of features and configuration options. The system uses a left‑sidebar menu with multiple nested options; new users often need two to four weeks of training to become proficient. Athena provides a robust training program (paid and included in implementation), as well as an online academy. Once mastered, the workflows become very efficient, especially for practices that use Athena’s full RCM and network tools. The mobile app (Athenahealth Mobile) is relatively robust, with chart review, secure messaging, and task management. However, some providers find the screen‑by‑screen data entry to be slower than Kareo’s more streamlined approach.

Integrations

Kareo (Tebra): 70/100

• Labs: Direct interfaces with Quest, LabCorp, and several regional labs (via eLab).
• Imaging: Limited – mainly via fax or partner services.
• Pharmacy: Electronic prescribing via Surescripts; EPCS supported.
• Patient engagement: Integrates with Updox (telehealth, broadcast messaging).
• Third‑party apps: Kareo has an open API, but its app marketplace is smaller than Athena’s. Popular integrations include revenue cycle partners and some population health tools.
• Interoperability: Direct secure messaging out of the box; can connect to some HIEs but not as deeply as Athena.

Kareo is adequate for typical independent practice needs, but it lacks the broad network connectivity that larger organizations require.

Athenahealth: 90/100

• AthenaNet® network: One of the largest healthcare networks in the US – connects to 160,000+ providers, 1,800 hospitals, 100,000+ clinical orders (labs, radiology), and virtually all major pharmacies.
• Labs: Direct connections to Quest, LabCorp, and hundreds of regional/hospital labs.
• Imaging: Integrated ordering and results receipt from many radiology centers (RIS interfaces).
• Payers: Built‑in eligibility, real‑time claim adjudication, and payer plan updates via the network.
• Health Information Exchange: Supports Carequality, CommonWell, and most regional HIEs out of the box.
• Marketplace (Athenaapp): Hundreds of apps and integrations for specialized workflows – analytics, population health, research, and more.

Athenahealth’s integration ecosystem is a major competitive advantage. Practices that rely heavily on external data exchange (labs, imaging, referrals, hospital feeds) will find Athena far superior.
