Top Medical Billing Companies in 2026

Medical billing is one of those functions that sounds straightforward until you're knee-deep in denied claims, underpayments, aging AR, and payer credentialing paperwork. For most practices, billing isn't just administrative overhead - it's the engine that keeps cash flowing. Get it wrong, and you're leaving significant revenue on the table.

The medical billing market has matured significantly in recent years. There are solid platforms designed specifically for small practices, specialty groups, and everything in between. Finding the right fit requires understanding which model you actually need: billing software your team operates, a fully outsourced RCM service, or human billing support that works alongside your existing system.

This guide covers eight of the leading medical billing companies and services in 2026 - their core capabilities, pricing, strengths, and where they fall short.

The 8 top medical billing companies:

1. Kareo Billing
2. AdvancedMD Billing Services
3. Athenahealth
4. DrChrono

Quick Comparison: Medical Billing Companies in 2026

---

1. Kareo Billing

What It Is

Kareo - now part of the Tebra ecosystem - has been a dominant name in cloud-based medical billing for independent and small practices for over 15 years. The platform was built specifically for small to mid-sized practices that need an all-in-one solution combining EHR, practice management, and billing without the enterprise complexity of larger systems. If you're a solo physician or running a small clinic, Kareo's billing module is one of the most recognized entry points in the market.

Key Features

• End-to-end claim submission and tracking
• Automated insurance eligibility verification before appointments
• Claims scrubbing to catch errors before submission
• Patient statements and online payment collection
• Integration with 60+ EHR platforms
• Analytics and revenue cycle reporting dashboard
• Patient portal for billing inquiries and payments
• Robotic process automation for routine eligibility and status checks

Pricing

Kareo Billing pricing is custom and typically subscription-based, starting around $300+ per month depending on practice size, specialty, and features selected. Pricing varies for physicians versus non-physician providers (e.g., PAs, DCs). You'll need to request a demo for an accurate quote.

Pros

• All-in-one platform means your EHR, scheduling, and billing data live in one place - no manual syncing between systems
• Built specifically for independent practices, so the interface reflects how small practices actually work
• Strong claims scrubbing reduces denial rates before claims hit the payer
• Over 60 EHR integrations if you don't want to switch your clinical documentation system

Cons

• Primarily designed for solo and small practices - mid-to-large groups often outgrow it
• Custom pricing with limited transparency makes budgeting harder upfront
• Customer support response times have been a recurring complaint in user reviews
• Now part of Tebra, which has introduced some product transition confusion

2. AdvancedMD Billing Services

What It Is

AdvancedMD offers a full-service Revenue Cycle Management (RCM) outsourcing solution, meaning they don't just give you billing software - they handle the billing for you. Their team manages claim submission, denial management, appeals, payment posting, and AR follow-up on your behalf. For specialty practices dealing with complex payer rules, prior authorizations, and high denial rates, the AdvancedMD billing services model is worth a serious look.

Key Features

• Fully outsourced RCM - their billing team handles the process end to end
• Specialty-specific workflows for over 60 medical specialties
• Automated claim scrubbing with specialty-specific coding rules
• Prior authorization management and tracking
• Denial management and appeals processing
• Patient billing and collections support
• Detailed financial reporting and KPI dashboards for practice owners

Pricing

AdvancedMD Billing Services typically charges a percentage of collections, ranging from approximately 4% to 9% depending on practice size, specialty, and claim volume. For high-revenue practices, this model can add up significantly - a practice collecting $2M annually could pay $80,000-$180,000 per year in billing fees.

Pros

• True outsourced billing means your staff isn't spending time on claims and follow-up
• Specialty-specific workflows reduce errors and denials compared to generic billing software
• Strong denial management and appeals process that most in-house teams struggle to maintain consistently
• Financial reporting gives practice owners clear visibility into revenue cycle performance

Cons

• Percentage-of-collections pricing scales with your revenue, which can become expensive as your practice grows
• Less suitable for very small practices where the minimum fees may not be cost-effective
• Some users report a learning curve with the broader AdvancedMD platform beyond just billing

3. Athenahealth

What It Is

Athenahealth operates one of the largest cloud-based EHR and billing networks in the United States, connecting thousands of practices to a shared payer intelligence infrastructure. The core differentiator is the athenaNet network - a continuously updated rules engine that learns from claims data across the entire Athenahealth client base, so your claims benefit from payer behavior patterns observed across the broader network. For practices that want sophisticated billing technology backed by real-time payer intelligence, Athenahealth is a serious contender.

Key Features

• Cloud-based EHR tightly integrated with billing and practice management
• Athena Collector - automated billing with payer-specific rules engine
• Large payer network with real-time eligibility and claims status
• Denial prevention using network-wide claim learning
• Patient engagement tools including online billing and payment plans
• Revenue cycle reporting and benchmark comparisons
• Coordinated care tools for multi-provider practices

Pricing

Athenahealth charges a percentage of monthly collections rather than a flat monthly fee. This aligns their incentives with your revenue performance but means your cost scales with your practice's growth. Specific percentages are negotiated per contract. Standalone EHR and practice management modules (without full RCM) can start around $140 per provider per month.

Pros

• Payer network intelligence is genuinely differentiated - the shared learning model improves claim accuracy across the platform
• Tight EHR-to-billing integration reduces manual entry errors and speeds up the billing cycle
• Strong reporting tools give detailed visibility into AR aging, denial trends, and payer performance
• Continuously updated payer rules without you needing to maintain them internally

Cons

• Contract terms can include lock-in provisions that make switching providers difficult
• Percentage-of-collections pricing rewards larger practices; smaller practices may find better value elsewhere
• Some users report that customer support quality varies significantly by market
• Implementation can be complex and time-consuming for practices transitioning from legacy systems

4. DrChrono

What It Is

DrChrono made its name as the first EHR platform built for iPad, and that mobile-first philosophy still defines the product. For practices that value flexibility - seeing patients in multiple locations, doing telehealth, or just preferring a tablet over a desktop - DrChrono combines EHR, practice management, and billing in a genuinely mobile-friendly package. It's particularly popular with smaller, tech-forward practices and concierge medicine providers.

Key Features

• iPad and iPhone native EHR - true mobile-first design, not a mobile-adapted desktop app
• Integrated billing with claim submission and tracking
• Automated patient eligibility checks before appointments
• Customizable clinical forms and templates
• Telehealth built directly into the platform
• Patient portal with online scheduling, intake forms, and bill payment
• Lab integrations and e-prescribing

Pricing

DrChrono pricing starts at $199 per provider per month for the basic plan and increases based on features and practice size. The full-featured plan with billing capabilities typically runs $299+ per provider per month.

Pros

• Best-in-class mobile experience - if your practice runs on tablets, nothing competes on ease of use
• All-in-one solution covers EHR, scheduling, telehealth, and billing in one subscription
• Intuitive interface requires less training time than many legacy systems
• Good fit for solo practitioners and small specialty practices

Cons

• Smaller support team than enterprise competitors - support response times can lag during peak periods
• Less depth in specialty-specific billing workflows compared to AdvancedMD or Athenahealth
• Reporting and analytics are less robust than practices with high billing complexity will need
• Some users report limitations in the billing module for complex claim scenarios

5. Tebra (formerly Kareo + PatientPop)

What It Is

Tebra was formed from the merger of Kareo (billing and practice management) and PatientPop (patient marketing and digital presence). The result is a platform that combines revenue cycle management with practice growth tools - you can manage claims, post payments, and run Google review campaigns from the same system. For independent practices that want to both optimize billing and grow their patient panel, Tebra's combined offering addresses both problems simultaneously.

Key Features

• Billing and claims management with automated scrubbing
• Online reputation management and patient review generation
• Patient scheduling, telehealth, and digital intake forms
• Patient marketing including SEO-optimized practice profiles
• Insurance eligibility verification and ERA auto-posting
• TriZetto integration for pre-submission claims scrubbing
• Analytics across both clinical and marketing performance

Pricing

Tebra's integrated platform costs $99-$399 per provider per month depending on the modules selected. Managed billing services have a separate pricing model involving a percentage of collections plus transaction fees. Custom quotes are required for the full picture.

Pros

• Unique combination of billing and patient marketing in one platform - genuinely useful for growth-focused practices
• Strong claim scrubbing through TriZetto integration reduces first-pass denial rates
• Digital patient intake reduces front desk workload and improves data accuracy
• Good for independent practices that want one vendor rather than multiple

Cons

• Modular pricing means adding features adds cost - the full platform can get expensive fast
• Merging two previously separate companies has created some workflow inconsistencies that users notice
• Customer support has received mixed reviews around communication and responsiveness
• Not ideal for large multi-specialty groups that need advanced enterprise RCM capabilities

6. Greenway Health

What It Is

Greenway Health is a healthcare technology company that provides EHR, practice management, and revenue cycle management solutions to multi-specialty physician groups, large practices, and ambulatory care organizations. Their platform - built on the Prime Suite and Intergy product lines - is designed to handle the complexity of multi-provider, multi-location practices where specialty-specific billing rules and workflow coordination become genuinely difficult to manage.

Key Features

• Multi-specialty EHR with specialty-specific templates and workflows
• Full revenue cycle management including billing, coding, and AR management
• Practice management across multiple locations and providers
• Population health management tools
• Data analytics and financial reporting
• Interoperability and data exchange with hospitals and health systems
• Regulatory compliance support (MIPS, MACRA)

Pricing

Greenway Health pricing is custom and varies by practice size, specialty mix, and the specific products and services engaged. Contact their sales team for a tailored proposal.

Pros

• Strong support for multi-specialty groups where different specialties have different billing requirements
• Deep compliance capabilities for regulatory reporting (MIPS, MACRA) that matter to larger practices
• Data analytics tools give meaningful insight into practice performance across providers and locations
• Long-standing platform with a large user community and established support infrastructure

Cons

• Interface is dated compared to newer cloud-native competitors - the user experience can feel older
• Implementation complexity and timelines are significant - budget time and resources accordingly
• Less compelling for small or single-specialty practices where the feature depth isn't needed
• Migration from older product lines (Prime Suite to Intergy) has caused some client friction

7. CureMD

What It Is

CureMD is an all-in-one healthcare technology platform covering EHR, practice management, and medical billing designed to be accessible to smaller practices without sacrificing capability. Positioned as an affordable full-suite alternative to more expensive platforms, CureMD aims to give independent practices enterprise-level tools at small practice prices. Their billing module includes automated claims, denial management, and patient billing in a single integrated system.

Key Features

• Denial management with automated alerts and follow-up workflows
• Patient billing with statements and online payment options

Pricing

Pros

• One of the more affordable full-suite options that combines EHR and billing without charging separately for each
• Accessible pricing makes it viable for solo and small practices on tighter budgets

• Less depth in analytics and reporting than practices with complex billing needs will want
• Limited brand recognition compared to Athenahealth or AdvancedMD may mean fewer integration partnerships

8. Stealth Agents

What It Is

Stealth Agents offers a different kind of medical billing solution: dedicated virtual assistants trained in medical billing and revenue cycle support who work alongside your existing team. Rather than replacing your billing software, Stealth Agents provides the human capacity to use it effectively - handling tasks like claim follow-up, denial research, patient billing inquiries, insurance verification, and prior authorization tracking. For practices that have the software but lack the staffing bandwidth, this model addresses the real bottleneck.

Key Features

• Dedicated virtual medical billing assistants (full-time or part-time)
• HIPAA-trained specialists familiar with billing compliance requirements
• Insurance eligibility verification and prior authorization support
• Claim submission, tracking, and denial follow-up coordination
• Patient billing inquiries and payment plan support
• AR aging review and follow-up on outstanding claims
• Flexible scaling - add capacity as your billing volume changes

Pricing

Stealth Agents plans start from approximately $1,600 per month for a dedicated virtual billing assistant. This makes it significantly more affordable than hiring a full-time in-house medical biller (typically $45,000-$65,000/year plus benefits) while providing dedicated, personalized support.

Pros

• HIPAA-trained virtual assistants who understand medical billing compliance - not generic VAs
• Genuinely flexible: scale your billing support up or down without HR overhead
• Cost-effective compared to in-house billing staff or percentage-of-collections RCM services
• Works alongside any billing software your practice already uses - no system migration required

Cons

• Not a billing software solution - Stealth Agents provides human support, not a platform
• Best positioned as a complement to existing billing systems, not a standalone RCM service
• The quality of support depends on effective onboarding and clear communication of your practice's specific workflows

Buying Guide: How to Choose a Medical Billing Company

Know whether you need software or service. Billing software (Kareo, DrChrono, CureMD) gives your team tools to manage billing internally. Outsourced RCM services (AdvancedMD, Athenahealth) handle billing for you. Virtual billing support (Stealth Agents) gives you trained human capacity without full outsourcing. Each solves a different version of the problem.

Understand percentage-of-collections pricing. Athenahealth and AdvancedMD charge a percentage of what you collect. This can feel like aligned incentives, but as your practice grows, your billing fees grow proportionally. Model out what you'd actually pay at your current and projected collection levels before committing.

Specialty fit matters. General billing software doesn't always handle specialty-specific coding rules well. If you're a behavioral health practice, a high-volume surgical group, or a complex multi-specialty organization, look specifically for platforms with proven experience in your specialty category.

Ask about denial rates and AR aging. Any vendor you're seriously evaluating should be able to share benchmark data on first-pass claim acceptance rates, denial rates, and average days in AR. If they can't or won't share this, treat it as a red flag.

Consider implementation burden. Switching billing systems is disruptive. Ask every vendor for a realistic implementation timeline, what internal resources you'll need to commit, and what happens to your billing during the transition period.

Don't overlook support. Billing issues are time-sensitive - a denied claim or a credentialing problem that sits unresolved for weeks is real revenue loss. Evaluate every vendor's support model: Is there a dedicated account manager? What are the guaranteed response times? How is escalation handled?

Your billing partner directly affects your practice's financial health. Take the evaluation seriously, involve your billing team in the selection process, and don't let a slick demo substitute for a candid reference conversation with an existing client in your specialty.
