Which Is Better: Tebra, Athenahealth, or eClinicalWorks?
All three are mature, well-supported PM platforms that fit different practice profiles. Tebra (formerly Kareo) is a strong fit for early-stage, solo, and small-practice settings (under 5 providers) where ease of setup, modern UI, and predictable per-user pricing matter most. Athenahealth is a strong fit for established and growing practices that value the percentage-of-collections pricing model (no software cost when collections are low), one of the industry's deepest payer-rule libraries, and a heavily-managed clearinghouse experience — though the percentage pricing scales as collections grow. eClinicalWorks is a strong fit for mid-market and multi-specialty practices (10-50 providers) needing comprehensive feature breadth, deep specialty support across many specialties, and stable per-user subscription pricing. The decision depends on practice size, specialty mix, pricing-model preference, and clinical-workflow priorities — not on a universal ranking.
- Tebra: best for solo and small practices (under 5 providers)
- Athenahealth: best for growing practices valuing managed-service depth
- eClinicalWorks: best for mid-market and multi-specialty practices
- Tebra pricing: per-user subscription, transparent
- Athenahealth pricing: % of collections, scales with revenue
- eClinicalWorks pricing: per-user subscription with feature tiers
- All three: integrated EHR + PM + billing on one platform
Tebra (Kareo) vs Athenahealth vs eClinicalWorks
Last updated
Tebra (formerly Kareo), Athenahealth, and eClinicalWorks are three of the most-used integrated EHR-PM platforms in US physician practice, each occupying a distinct position in the market. Tebra targets early-stage and small practices with a clean modern interface and aggressive small-practice pricing. Athenahealth targets established and growing practices with a percentage-of-collections pricing model and one of the deepest clearinghouse and payer-rule libraries in the industry. eClinicalWorks targets mid-market and multi-specialty practices with a comprehensive feature set and broad specialty support, traditionally on per-user subscription pricing. None of these platforms is universally 'best.' Each is genuinely strong for the practice profile it targets and weaker in the contexts other platforms serve better. This comparison describes what each platform does well, where the trade-offs sit, and which practice profile each one fits. The goal is decision-quality information, not platform advocacy. This is a three-way comparison rather than a head-to-head. The three platforms compete in overlapping but distinct market segments, and the real decision is usually 'which of these three (or which other platform) fits my practice profile' rather than 'A or B.' Reference data is publicly available platform documentation, MGMA technology benchmarks, KLAS Research vendor reports, and current platform pricing as of 2024-2025.

Tebra (Formerly Kareo): Strengths and Profile
Tebra is the result of the 2022 merger of Kareo (a small-practice billing-and-PM platform) and PatientPop (a marketing and practice-growth platform). The combined product has been actively rebuilt to integrate billing/PM, EHR, patient engagement, and marketing under one platform with a modern UI. The pricing model is per-user subscription, generally transparent, with tiers from solo-practice basic to multi-provider full-suite. Where Tebra is strong: ease of setup and onboarding (designed for self-serve and light-touch implementation, particularly suited to solo and small practices that do not have IT staff); modern user interface (the rebuilt Tebra platform is one of the cleaner UIs in the PM market and reduces clinician training time); pricing transparency (per-user subscription is easier to budget than percentage-of-collections); patient-engagement and marketing integration (the PatientPop merger added online-presence management, patient acquisition tools, and reputation management that integrate with the PM); and fit for new and scaling practices (the platform supports practices through their early growth stages without requiring migration to enterprise tooling). Where Tebra is weaker: clinical workflow depth in specialty contexts compared to specialty-specific EHRs (Tebra's clinical module is improving but is not as deep as Modernizing Medicine for ophthalmology or TherapyNotes for behavioral health); advanced multi-specialty workflows in larger groups (Tebra is optimized for small-practice scale rather than 20+ provider multi-specialty operations where eClinicalWorks or Athena have more depth); and reporting depth for analytics-driven management (Tebra's reporting is improving but historically lighter than enterprise platforms). Ideal practice profile: 1-5 providers, single specialty or simple multi-specialty mix, solo or first-time practice owner, value modern UX and predictable pricing, do not have dedicated IT staff.
Athenahealth: Strengths and Profile
Athenahealth (now part of Bain Capital and Veritas Capital ownership after a 2022 transaction, operationally still 'Athena' in market) takes a fundamentally different commercial model than most PM platforms: percentage-of-collections pricing rather than per-user subscription. The implication is that Athena's commercial incentive is aligned with the practice's collections — when the practice grows, Athena's revenue grows; when the practice underperforms, Athena's revenue is constrained. This shapes how Athena operates the platform. Where Athenahealth is strong: the deepest payer-rule library in the industry (Athena maintains its own clearinghouse, AthenaCollector, and continuously updates payer-specific rules across thousands of payers nationally — this typically translates to lower denial rates than self-managed clearinghouse setups); strong managed-service component (Athena handles substantial back-office work including denial follow-up and A/R support depending on contract tier, blurring the line between software and service); broad national payer-mix support (extensive Medicare, Medicaid, and commercial payer connections, including specialized payers); ongoing platform improvements funded by collections-based revenue (incentive to maintain and improve the platform is structural); and good fit for growing practices because cost scales with revenue rather than imposing a fixed line on early-stage practices. Where Athenahealth is weaker: pricing transparency (percentage-of-collections obscures total cost-of-ownership comparison and can become expensive at higher revenue scales — typically 4-7% of collections, sometimes higher); platform UI/UX has historically been dense and less modern than Tebra (Athena has invested in UI modernization, with mixed results); customization for specialty workflows requires either choosing AthenaClinicals tier or accepting some workflow-fit compromises; switching cost is high and platform lock-in concerns have surfaced in past disputes around data export. Ideal practice profile: 5-50+ providers, growing practice, value managed-service depth and want vendor incentives aligned with collections, do not require deeply specialty-specific clinical workflows, prefer collections-based pricing for cash-flow predictability.
eClinicalWorks: Strengths and Profile
eClinicalWorks is a comprehensive integrated EHR-PM platform with one of the broadest installed bases in US physician practice, particularly strong in mid-market and multi-specialty groups. Pricing is per-user subscription with feature tiers (eClinicalWorks Cloud Practice, V12 versions, with optional add-ons for advanced reporting, telehealth, and specialty modules). Where eClinicalWorks is strong: comprehensive feature breadth covering virtually every general physician-practice need (from scheduling to EHR documentation to billing to A/R management to patient engagement to telehealth); broad specialty support across many specialties with specialty-specific templates and workflows (cardiology, pediatrics, OB/GYN, gastroenterology, orthopedics, internal medicine, family practice, urgent care); strong reporting and analytics capabilities once configured (eClinicalWorks Insights and Healow Analytics layer); large practice-scale operational support (handles 50-100+ provider groups effectively); active developer community and customization options; and broad clearinghouse and payer connectivity (Trizetto Provider Solutions integration as default, with support for others). Where eClinicalWorks is weaker: UI density and learning curve (eClinicalWorks has historically been criticized for a dense interface and steeper provider training requirements compared to Tebra's modern UI); implementation complexity (typical implementation runs 90-180 days, requiring more dedicated practice resources than Tebra's lighter setup); historical compliance and reporting issues (eClinicalWorks settled with the DOJ in 2017 over false-attestation claims related to meaningful use certification, an event that affected market trust at the time though the platform has since invested in compliance and quality assurance); and per-user subscription pricing that scales linearly with practice size (favorable for mid-market, less favorable for very small practices where Tebra's small-practice pricing is more efficient). Ideal practice profile: 10-50+ providers, multi-specialty practice, established operations with dedicated IT or practice manager staff, value comprehensive feature breadth, want stable per-user subscription cost rather than collections-based pricing.
Pricing Model Comparison: Three Different Approaches
The three platforms take three substantially different pricing approaches, and understanding them is critical to a real cost comparison. Tebra prices per-user per-month on transparent published tiers. Small-practice pricing typically runs $300-$700 per provider per month for the integrated EHR + PM + billing module, with optional patient-engagement and marketing add-ons priced separately. Implementation is light-touch and often included or low-cost. Total annual cost for a 3-provider practice is approximately $11,000-$25,000 plus any add-ons. Athenahealth prices as a percentage of collections — typically 4-7% depending on contract tier, with higher tiers including more managed-service components (denial work, A/R support, collections optimization). The percentage-of-collections model has the structural advantage of scaling with practice revenue (a struggling practice does not pay enterprise software prices) and the structural disadvantage of becoming expensive as collections grow (a $10M practice on a 6% Athena rate pays $600,000 annually for the platform plus services). For a 6-provider practice with $2.4M collections at a 6% rate, annual cost is $144,000. eClinicalWorks prices per-user per-month with feature tiers. Pricing is generally negotiated rather than published, with mid-market typical rates of $400-$700 per provider per month for the comprehensive EHR + PM tier. Implementation is structured and vendor-led, typically $25,000-$80,000 for a mid-market multi-specialty practice. Total annual cost for a 6-provider practice is approximately $30,000-$50,000 plus implementation amortization. The pricing comparison is therefore not directly apples-to-apples: Athena's percentage includes substantial managed-service components that would be billed separately under Tebra or eCW; Tebra's lower per-provider pricing reflects smaller-practice scale assumptions; and eClinicalWorks' pricing assumes mid-market operational maturity. Net cost-of-ownership for the three platforms typically lands within 30-50% of each other for similar-sized practices when services are normalized.
Decision Factors: How to Choose Among the Three
Walk through the decision factors that matter in selection. Practice size: under 5 providers strongly favors Tebra (small-practice pricing, light-touch implementation, modern UI for owner-operators). 5-15 providers can fit any of the three depending on other factors. 15-50+ providers favors eClinicalWorks or Athenahealth for operational depth. Specialty: general primary care and multi-specialty fit any of the three well. Specialty-deep practices may want to evaluate specialty platforms (Modernizing Medicine for ophthalmology/derm/ortho, TherapyNotes for behavioral health) before defaulting to one of these three. Among the three, eClinicalWorks has the broadest specialty-specific template library; Athena has strong general-practice rule libraries; Tebra has growing specialty support. Pricing model preference: practice owners who value cost predictability and want to budget software as a fixed line favor per-user subscription (Tebra or eCW). Practice owners who prefer cost to scale with revenue (so software is cheaper when revenue is constrained) favor Athena's percentage-of-collections. Managed-service depth needed: practices wanting the platform to absorb meaningful back-office billing work (denial follow-up, A/R support, collections optimization) lean toward Athena. Practices running their own billing operations or using a separate billing service alongside the PM lean toward Tebra or eCW. Implementation timing: practices that need to get live within 30-45 days favor Tebra's light-touch implementation. Practices with 90-180 day runway can implement Athena or eCW with proper structure. Long-term scaling: practices planning to grow beyond 15 providers or expand into new specialties should evaluate Athena and eCW more seriously than Tebra, which is optimized for small-to-mid practice scale rather than enterprise expansion. Tebra users sometimes migrate to one of the other platforms when they grow past 10 providers.
How MedPrecision Works With Each Platform
As an outsourced billing service, MedPrecision works within whichever PM platform the practice uses. We have direct operating experience with all three of these platforms and many others (NextGen, AdvancedMD, DrChrono, Allscripts/Veradigm, specialty platforms). Our perspective on each is operational rather than promotional. With Tebra-based practices: the modern UI and clean workflow translate to faster onboarding for our billing team and easy collaboration with practice staff. Tebra's billing module integrates well with our standard processes for charge validation, claim submission, denial work, and A/R follow-up. The platform's small-practice scale aligns well with our typical client profile. With Athenahealth-based practices: Athena's payer-rule library and managed-service components mean some of the work we typically handle for clients is partially absorbed by Athena itself; we coordinate with Athena's denial and A/R workflows rather than duplicate them. The percentage-of-collections pricing model means practices using Athena often have less appetite for additional billing-service costs, so the relationship is sometimes scoped narrower (focused denial work, complex appeals, specialty-specific support) rather than full-service. With eClinicalWorks-based practices: the platform's depth and customization mean we tailor workflow templates and reports to the specific practice's eCW configuration. Multi-specialty groups using eCW often have complex denial patterns that benefit from specialty-trained billing-team focus, which is where outsourced services typically add the most measurable value. In all cases, the platform choice shapes the operational details, not the fundamental decision of whether outsourced billing fits the practice. The platform-vs-billing-service decision is upstream of platform selection: a practice running any of these three can productively work with a billing service partner if the operational fit is right.
When to Choose Each Option
Tebra (formerly Kareo)
Choose Tebra (formerly Kareo) if you are a solo practitioner or a small practice (1-5 providers) launching a new practice or operating an established small practice; you value modern UI/UX and predictable per-user subscription pricing; you do not have dedicated IT staff and need light-touch implementation; you do not require deep specialty-specific clinical workflows that specialty EHRs would provide; or you are scaling but not yet at the operational scale where eClinicalWorks or Athenahealth would be more appropriate.
Athenahealth, eClinicalWorks (multi-platform comparison)
Choose Athenahealth if you value the percentage-of-collections pricing model (scales with revenue, no fixed software cost when revenue is constrained), want one of the industry's deepest payer-rule and clearinghouse libraries managed for you, want substantial managed-service depth in denial work and A/R support, and are growing or established with collection volumes that support the percentage-pricing economics. Choose eClinicalWorks if you are a mid-market or multi-specialty practice (10-50+ providers) needing comprehensive feature breadth and broad specialty support; you have dedicated IT or practice-manager staff who can implement and operate a comprehensive platform; you prefer stable per-user subscription pricing over collections-based; or you operate complex multi-specialty workflows where eCW's specialty template library has clear advantages.
Tebra (formerly Kareo), Athenahealth, and eClinicalWorks are three mature, well-supported PM platforms each fitting distinct practice profiles. Tebra is the strong choice for solo and small practices (1-5 providers) prioritizing modern UI, predictable subscription pricing, and light-touch implementation. Athenahealth is the strong choice for growing practices that value the percentage-of-collections pricing model, deep payer-rule libraries, and managed-service depth. eClinicalWorks is the strong choice for mid-market and multi-specialty practices (10-50+ providers) needing comprehensive feature breadth, broad specialty support, and stable subscription pricing. None is universally best; the right platform is the one matched to your practice size, specialty mix, pricing preference, and operational maturity. Evaluate against a shortlist of 3-5 platforms matched to your profile and base the decision on reference-customer experience rather than demo polish.

Get a Free Billing Audit arrow_forwardIs Tebra better than Kareo? They are the same product now, right?
Tebra is the rebrand and merger result of Kareo and PatientPop, which combined in 2022. The merged platform takes the strongest elements of both: Kareo's billing and PM strength plus PatientPop's marketing and patient-engagement capability, integrated under a modernized UI. Existing Kareo customers were migrated to the unified Tebra platform over 2022-2024. Tebra is therefore not 'better than Kareo' so much as 'Kareo plus additional capability under a refreshed brand and updated platform.' For practices that used Kareo previously, the Tebra experience adds patient-acquisition and engagement features without losing the billing-and-PM core. New practice owners evaluating Tebra are seeing a more comprehensive platform than Kareo offered standalone in pre-merger years. The platform continues active development and feature expansion.
Why does Athenahealth charge percentage-of-collections instead of subscription?
Athenahealth's percentage-of-collections pricing model is a deliberate strategic choice that aligns Athena's commercial incentive with the practice's revenue performance. When the practice collects more, Athena earns more — which structurally incentivizes Athena to invest in features that drive higher collections (denial-rule libraries, payer-specific edits, A/R support tooling, managed-service components). When the practice underperforms, Athena's revenue is constrained, which means the practice does not pay full enterprise software prices during a difficult period. The practical effect is that Athena is more software-plus-managed-service than software-only; the percentage covers both the platform and a substantial managed-service layer that competing per-user-subscription platforms do not natively include. The trade-off for the practice: less pricing transparency (the total annual cost is harder to project than a fixed per-user fee), and potentially higher cost as collections grow into mid-market scale. The model fits practices that value vendor-incentive alignment and cash-flow-aligned pricing; it fits less well for very large stable practices where fixed-cost predictability is more valuable than incentive alignment.
Did the eClinicalWorks DOJ settlement affect the platform's reliability?
The 2017 settlement between eClinicalWorks and the US Department of Justice resolved allegations that the company falsely certified its software for the federal Meaningful Use program. eClinicalWorks paid $155 million in the settlement and entered a five-year corporate integrity agreement. The settlement was a meaningful event affecting market trust at the time, particularly for practices considering eCW for incentive-program compliance. Subsequent to the settlement, eCW invested substantially in compliance, quality assurance, and certification rigor; subsequent ONC certifications and platform releases have not produced repeat issues. Operationally, the platform has maintained one of the broader installed bases in physician practice and continues active development. For practices evaluating eCW today, the settlement is historically relevant context but is not a current operational issue affecting platform reliability in 2024-2025. Practices should still conduct standard due diligence on certification status, but the post-settlement track record has been generally clean.
Which platform has the easiest implementation?
Tebra is generally the easiest implementation for small practices because the platform is designed for self-serve and light-touch onboarding — typical implementations run 30-60 days for solo and small practices, with online onboarding resources, video training, and lightweight vendor support. Athenahealth implementation is structured and vendor-led, with implementation managers and detailed phase plans; typical timeline is 90-180 days depending on practice size and integration complexity, and the implementation is generally smooth but more involved than Tebra's. eClinicalWorks implementation is the most comprehensive of the three, with vendor-led project management, detailed configuration phases, and substantial training requirements; typical timeline is 90-180 days for mid-market multi-specialty implementations. The pattern reflects target-market scale: Tebra's small-practice focus rewards rapid onboarding; Athena's and eCW's larger-practice focus accommodates more complex implementation cycles. Practices should plan resources accordingly.
How do these three compare on specialty support?
All three support general practice well; specialty depth varies. eClinicalWorks has the broadest specialty-specific template library among general PM platforms, with established workflows for cardiology, pediatrics, OB/GYN, gastroenterology, orthopedics, family practice, urgent care, and many others — making it a strong default for multi-specialty groups and mid-market specialty practices. Athenahealth has solid general-practice depth with specialty configurations available, particularly strong on payer-rule complexity for specialty billing. Tebra has growing specialty support but is generally less specialty-deep than eCW or Athena, particularly in specialties with very specific workflow requirements. For practices in specialties with materially better specialty-specific EHRs (Modernizing Medicine for ophthalmology/derm/ortho, TherapyNotes/SimplePractice for behavioral health, WebPT/Raintree for PT, specialty cardiology platforms), evaluating those specialty platforms alongside or instead of these three is often the right move — none of the three matches a deep specialty platform on its own specialty turf.
Can I switch between these platforms without losing data?
Yes, but the switch is a major project. All three platforms support data export in industry-standard formats (CCDA for clinical records, HL7 for messages, CSV/database export for billing and A/R data), but the practical migration involves substantial effort: clinical data migration with template re-mapping, fee schedule and payer enrollment transfer, historical A/R reconciliation, user training on the new system, and a parallel-run period during cutover. Typical inter-platform migrations cost $25,000-$150,000 in implementation services depending on data volume, complexity, and customization, and produce 10-20% productivity loss during the 60-90 day transition window. Practices switch most often when current platform performance is unsatisfactory and the cost-benefit of switching exceeds the transition cost. Switching for incremental improvement rarely pencils out; switching to access materially better fit (specialty-platform migration, scale-driven move from Tebra to eCW, or strategic move to Athena's managed-service model) is more common and more justifiable.
Which is most popular for small practices specifically?
Tebra (and pre-merger Kareo) has historically been one of the most-used PM platforms for solo and small practices in the 1-5 provider range, with AdvancedMD and DrChrono also strong in this segment. Athenahealth and eClinicalWorks both serve the small-practice segment but are more commonly found at 5+ provider scale where their broader feature sets and managed-service components produce more value. Within the small-practice segment, Tebra's modern UI, transparent pricing, light-touch implementation, and integrated patient-engagement (post-PatientPop merger) make it a popular default for new practice owners and solo practitioners. The MGMA technology benchmarks show Tebra/Kareo, AdvancedMD, and DrChrono consistently among the top platforms by small-practice market share, though specific year-over-year rankings shift. Practice owners evaluating Tebra should also look at AdvancedMD and DrChrono in the same evaluation cycle since these compete for similar small-practice profiles.
Do these platforms work with outside billing services?
Yes — all three platforms support outside billing service relationships, though the operational details differ. Tebra is straightforward for outside billing services to operate: the vendor's staff accesses the practice's Tebra account via standard credentialing, and the workflow is familiar to most billing services. Athenahealth's percentage-of-collections model includes substantial managed-service depth, which means outside billing services often coordinate with rather than duplicate Athena's denial and A/R workflows; the relationship is typically scoped narrower (specialty-focused work, complex appeals, supplementary depth) rather than full back-office service. eClinicalWorks supports outside billing services across the full range of involvement, from limited specialty-focused work to complete back-office operation; the practice typically owns the eCW subscription and the billing service operates within it. Practices considering outside billing services should confirm that the service has direct experience with their specific platform — platform-specific expertise translates to faster onboarding and lower error rates compared to a service learning the platform during the engagement.
Are there other platforms I should evaluate beyond these three?
Yes, depending on practice profile. For small-practice owner-operators, also evaluate AdvancedMD (strong solo and small-group fit, transparent per-provider pricing) and DrChrono (cloud-native, particularly popular with Apple-ecosystem users and smaller practices). For mid-market multi-specialty groups, also evaluate NextGen (strong large-practice depth, broad specialty support) and Allscripts/Veradigm (Sunrise for hospital-affiliated, Pro for ambulatory). For specialty-specific workflows, evaluate the specialty platforms before defaulting to general PM platforms: Modernizing Medicine (ophthalmology, derm, ortho, plastic surgery, OBGYN), TherapyNotes and SimplePractice (behavioral health), WebPT and Raintree (physical therapy), Phreesia (patient intake and engagement, used alongside other PMs), Practice Fusion (basic EHR, now part of Veradigm). For hospital-affiliated practices, the parent hospital's enterprise EHR (Epic, Cerner/Oracle Health, Meditech) usually drives platform selection regardless of preference. The right shortlist for evaluation is typically 3-5 platforms matched to your specialty mix, practice size, and pricing-model preference.
How should I structure a platform evaluation?
Run a structured evaluation: define requirements (clinical workflow needs, billing depth, reporting, integration, specialty fit, growth plans), shortlist 3-5 platforms matched to your profile, request live demos with your specific specialty workflows and your top 3-5 payers represented, request reference customers from each vendor (specifically practices similar to yours in size and specialty), evaluate pricing on total cost of ownership (subscription + implementation + add-ons + clearinghouse + interface costs as relevant) over 5 years rather than year-one alone, evaluate switching cost (data export rights, exit assistance commitments, contract terms), and run a small pilot or proof-of-concept where feasible. Avoid making the decision based primarily on demo polish (all major platforms demo well); base it on reference-customer experience at 6-12 months post-implementation. Allow 60-90 days for the evaluation cycle and budget vendor due diligence time appropriately. The platform decision typically holds for 5-10 years, so evaluation rigor pays for itself.
