DrChrono

If you mean medical billing / revenue-cycle vendors for a U.S. medical practice, I’d shortlist these first. There is no single “best” for every practice—the right choice depends heavily on specialty, payer mix, practice size, and whether you want software only or outsourced billing/RCM service.

Best overall shortlist

My practical recommendations

If you’re a small independent medical practice

Start with:

1. athenaOne — best “serious” integrated RCM/EHR option if you can tolerate percentage-of-collections pricing and a more structured workflow.
2. Tebra — best familiar small-practice option, especially if you’re coming from Kareo or want billing + patient engagement.
3. AdvancedMD — best if you want more billing-control depth and scalability than the lightest small-practice tools.

For general medical-billing software lists, names like Tebra, AdvancedMD, DrChrono, athenahealth, EZClaim, Therabill, CollaborateMD, TotalMD, RXNT, and NextGen show up repeatedly in buyer guides and software directories; Forbes’ 2026 medical billing software list, for example, includes several of those brands.

If you’re a behavioral health / therapy practice

Start with:

1. TherapyNotes — usually stronger if insurance billing workflow is a priority.
2. SimplePractice — very popular, easier for many solo clinicians, but watch claim/insurance feature pricing and workflow changes.
3. Tebra or AdvancedMD — if you’re a larger behavioral-health group and need more traditional medical-practice billing/RCM controls.

If you’re a large group, MSO, hospital, or health system

Start with:

1. R1 RCM — strong ambulatory outsourced RCM reputation.
2. Ensemble Health Partners — strong end-to-end revenue-cycle outsourcing choice for larger organizations.
3. AGS Health / Optum / Omega / Access Healthcare / CorroHealth / GeBBS — worth including in an RFP if you need coding, AR, denial management, offshore/onshore staffing, or enterprise-scale RCM operations.

Best “actually used” brands to demo first

If you only want a tight demo list, I’d do this:

• General private practice: athenahealth, AdvancedMD, Tebra
• Small/solo practice: Tebra, DrChrono, athenahealth
• Behavioral health: TherapyNotes, SimplePractice, Tebra
• Multi-specialty group: AdvancedMD, athenahealth, NextGen
• Enterprise outsourced RCM: R1 RCM, Ensemble, AGS Health
• Claims/clearinghouse or revenue-cycle infrastructure: Waystar, Quadax, Experian Health — KLAS’s 2026 RCM category winners include Quadax for claims management/clearinghouse, Waystar for patient access, and Experian Health for contract management. (klasresearch.com)

What I’d ask before signing

Ask each vendor for:

• First-pass clean-claim rate
• Denial rate by payer
• A/R over 90 days
• Net collection rate
• Who works denials and appeals
• Whether coding is included
• Whether prior auth is included
• Whether they post ERAs automatically
• Reporting access in real time
• Contract term and termination rights
• Data export terms if you leave
• Whether staff are U.S.-based, offshore, or blended
• Specialty-specific references

My bias: for most practices, don’t choose purely on the lowest percentage of collections. A cheaper billing company that misses denials, under-codes, or fails to work A/R can cost far more than a higher-priced vendor with better follow-up.

Based on current industry coverage, here's a breakdown of the medical billing options people actually use — split into established software/RCM platforms and full-service outsourced billing companies, since "best" depends on whether you want software to bill in-house or a company to handle billing for you.

Well-Established Platforms (Software + Billing Services)

These are the most widely recognized names that repeatedly show up across independent comparisons:

Athenahealth – A major enterprise player. It offers a variety of revenue cycle management (RCM) and billing solutions, including medical claim processing, patient billing, medical coding, insurance verification, billing customization, and denial management, with notable clients including federally qualified health centers, medical groups, and hospitals. It's often ranked as best for large groups, winning on its enterprise network for large facilities.

AdvancedMD – Frequently cited as best for complex suites, winning on multi-specialty workflows.

Tebra (formerly Kareo) – Popular with smaller practices, often noted as best for marketing, winning on patient acquisition tools.

DrChrono – A mobile-friendly option, ranked as best for iPad users, winning on its mobile-first EHR.

CareCloud – Another major cloud-based platform commonly compared alongside the above for combining EHR and billing.

Dedicated Medical Billing / RCM Outsourcing Companies

If you want a company to fully manage billing rather than software you operate yourself:

Medical Billers and Coders (MBC) – A long-standing specialty billing firm known for depth of coverage: it operates dedicated Centers of Excellence across 40+ medical specialties—from wound care and orthopedics to anesthesia, gastroenterology, pain management, and behavioral health—with certified coders and payer-specific contract analytics.

CureMD – Positions itself around integration, since it integrates its medical billing services directly with its EHR and practice management platform, creating a seamless workflow that reduces administrative burden.

Transcure, MediBillMD, ReveleMD, Practolytics, DoctorPapers – These come up frequently in industry roundups as mid-size RCM/outsourcing firms serving independent and small-to-mid practices, alongside larger names.

Important Caveat

Worth noting: many "top medical billing" lists found online misrepresent their rankings, often including large software companies trying to sell subscriptions rather than genuine service-based billing partners. Several of the "top 10" lists in search results are published by the billing companies themselves (self-promotional SEO content), so treat rankings that place a lesser-known firm at #1 with some skepticism.

What Actually Matters When Choosing

Since average claim denial rates are reaching around 12% nationally—meaning roughly $12,000 potentially lost for every $100,000 billed, the real differentiators to evaluate are:

• Denial management track record (ask for actual denial rate %, not marketing claims)
• Specialty-specific coding expertise (billing for cardiology ≠ billing for behavioral health)
• Transparent pricing (percentage-of-collections vs. flat fee)
• Contract flexibility (some newer players compete specifically on no long-term contracts)

There’s no single “best” medical billing company — it depends on your practice size, specialty, whether you want software or full-service billing, and your budget. Here are the most widely used and highly rated medical billing companies/products in 2024, broken down by category.

Top Medical Billing Software (do billing in-house)

These are cloud-based platforms your staff uses to enter charges, submit claims, post payments, and track denials.

Best Full-Service Medical Billing / RCM Companies

If you’d rather outsource billing entirely, these companies manage claims, denials, payment posting, patient statements, and follow-up for you.
