Top medical billing companies in the United States, ranked by ChatGPT answers

If you're evaluating medical billing / revenue-cycle management (RCM) companies in the U.S., there isn't one universally best provider—the right choice depends heavily on whether you're a solo physician, specialty group, ASC, hospital, or health system.

Based on current 2026 information, these are companies I'd put on a serious shortlist, rather than treating any published “top 10” ranking as authoritative:

Current industry guides also consistently identify names such as athenahealth, CareCloud, AdvancedMD, CureMD, R1 RCM, Tebra, Transcure and eClinicalWorks among companies worth comparing.

How I'd narrow the field

For a solo or small physician practice: Look first at athenahealth, Tebra, AdvancedMD, CareCloud, and specialized boutique billing firms. The economics and service model are generally more important than the sheer scale of the vendor.

For a 10–100 provider specialty group: I'd investigate athenahealth, AdvancedMD, CareCloud, R1 RCM, AGS Health, and specialty-focused billing firms. Specialty expertise becomes particularly important because coding, authorization and payer rules can differ substantially.

For a hospital or health system: The relevant category is really enterprise RCM outsourcing, where Ensemble, R1 RCM and AGS Health are much more comparable than small physician-billing companies. Ensemble, for example, describes its offering as managing the revenue cycle from patient engagement through account resolution.

If you primarily want software + billing rather than outsourcing: athenahealth, AdvancedMD, Tebra, CareCloud and eClinicalWorks deserve closer examination.

What I would compare before signing

Don't choose based primarily on a vendor's advertised “collection rate.” Ask each company for:

• Clean-claim rate
• First-pass payment rate
• Days in A/R
• A/R over 90 days
• Denial rate and denial-recovery rate
• Percentage of collections charged as the fee
• Any minimum monthly fees
• Contract length and termination provisions
• Who handles coding and charge capture
• Credentialing/enrollment responsibilities
• Prior authorization support
• Patient collections
• HIPAA/security practices
• EHR/PM integrations
• Specialty-specific experience
• References from practices of comparable size

One particularly important distinction is billing-only vs. full RCM. A company that merely submits claims isn't equivalent to one handling eligibility, authorization, coding, claim submission, denials, A/R, payment posting and patient collections.

If you tell me your specialty, number of providers, approximate monthly claims, and whether you're looking for billing-only or full RCM, I can narrow this to 5–7 companies that are specifically appropriate for your practice and compare their pricing models, specialties, pros/cons, and contract considerations.

For small and mid-size U.S. medical practices, I’d build the shortlist around Tebra, AdvancedMD, CareCloud, athenahealth, and Medical Billers and Coders (MBC). The important distinction is whether you want billing software that your staff operates or a fully outsourced billing/RCM company. Current 2026 comparisons consistently make that distinction.

Shortlist

These aren't rankings; they're different fits for different operating models. For example, Tebra is repeatedly positioned toward smaller independent practices, while AdvancedMD and CareCloud are more commonly discussed for growing or mid-size groups. MBC is an outsourced-services option rather than simply another EHR/PM product.

If you want outsourced billing, not software

I'd specifically investigate:

• Medical Billers and Coders (MBC) — broad specialty coverage and dedicated billing/RCM services.
• CareCloud RCM — billing, coding and analytics for independent groups.
• athenahealth — particularly if you are willing to use its integrated platform and want a managed revenue-cycle model.
• AdvancedMD RCM — useful where you want billing services closely integrated with practice-management/EHR software.
• Transcure / GeBBS / Coronis Health — worth adding to an RFP if you're a larger or more specialized mid-size group. A 2026 comparison of mid-size physician-group vendors includes all three.

What I would compare before signing

Don't select a billing company based primarily on its percentage of collections. Ask every vendor for:

• Net collection rate
• First-pass/clean-claim rate
• Denial rate, broken down by payer
• A/R over 90 days
• Who handles denials and appeals
• Whether coding is included
• Whether eligibility/prior authorization is included
• ERA/EOB posting and reconciliation
• How often you'll receive detailed RCM reports
• Whether you get a dedicated account manager
• Which EHRs they integrate with
• Where their billing staff are located
• Contract length and termination provisions
• Exactly what happens to your data if you leave

Industry pricing commonly falls somewhere around 4–10% of collections, but quotes vary considerably based on specialty, claim volume, services included, and practice size. Current sources specifically caution that published rates are often incomplete or unavailable until a sales quote.

If you tell me your specialty, number of providers, approximate monthly claims, current EHR (e.g. Epic, eClinicalWorks, athenahealth, Tebra, AdvancedMD), and whether you want completely outsourced billing, I can narrow this to 3–5 companies and compare their pricing, contract terms, specialties, and capabilities.

For U.S. specialty practices where denial management is a major priority, I’d focus less on generic “medical billing” rankings and more on whether the vendor has specialty-specific coding, payer expertise, denial analytics, appeals, and measurable A/R performance.

A practical shortlist to evaluate is:

The three I'd put through an RFP

1\. GeBBS — especially worth evaluating if you have a substantial denial/A/R problem. GeBBS explicitly supports specialty-specific RCM and describes denial workflows covering root-cause analysis, corrections, appeals, payer follow-up and trend reporting. It also says its professional-fee coding operation covers 60+ specialties.

2\. R1 RCM — particularly relevant if your denials involve medical necessity, documentation, utilization review or clinical appeals, rather than simply eligibility/registration errors. R1 reports dedicated physician-advisory services and describes clinical denial recovery, peer-to-peer appeals and root-cause analysis.

3\. Experian Health — I'd consider this when the objective is not just outsourcing collections but preventing denials upstream. Its platform includes claim editing, denial workflow management, automated claim-status information, denial analytics and tools intended to identify high-risk claims before submission.

What I'd demand from the vendors

For a specialty practice, I wouldn't select a billing company based primarily on its advertised collection percentage. Ask each finalist for specialty-specific, client-level metrics, ideally for practices similar to yours:

• Clean-claim rate / first-pass acceptance rate
• Initial denial rate
• Denial overturn rate
• Dollars recovered from denials
• A/R days
• A/R >90 and >120 days
• Net collection rate
• Percentage of claims worked within payer appeal deadlines
• Average time from denial → appeal → resolution
• Top 10 denial reasons and their dollar impact
• Payer-specific denial rates
• Coding-error rate
• Eligibility/prior-authorization denial rate
• Underpayment detection and recovery
• How much work is performed by certified specialty coders
• Whether you get a dedicated account manager and dedicated billing/denial team
• What happens to old A/R when you transition

This is important because two vendors can both advertise “95%+ clean claims” while having dramatically different performance on high-dollar specialty claims and aged A/R.

One important distinction

If by denial management you mean ordinary insurance denials—eligibility, authorization, coding, modifier, timely filing, coordination of benefits, etc.—a conventional outsourced RCM company such as GeBBS may be appropriate.

If you're dealing heavily with clinical/medical-necessity denials, I'd put considerably more weight on a vendor's ability to perform clinical review and physician-to-physician appeals. R1 specifically describes physician/RN review and payer peer-to-peer appeals for this type of denial.

And if your goal is to reduce the number of denials before they occur, rather than simply work the resulting denials, technology such as Experian Health's claims and denial-management tools becomes more relevant.

If you tell me your specialty (e.g., cardiology, orthopedics, GI, dermatology, oncology), number of providers, approximate monthly claims, and whether you're looking for full-service billing or primarily denial/A/R recovery, I can narrow this to 5–7 vendors and compare their specialty expertise, pricing model, outsourcing model, technology, and denial capabilities.

There isn’t a reliable public dataset that lets me rank U.S. medical billing/RCM companies by both collection speed and denial rate on an apples-to-apples basis. Vendors report different definitions, specialties, client mixes, and time periods. The more useful comparison is to identify companies that publish verifiable performance metrics and then require the same KPIs from each bidder.

Companies worth putting on an RFP shortlist

For context, current benchmark sources put healthy physician-practice performance around <5–10% initial denials, <35–40 A/R days, 95–97% net collections, and ≥95% clean claims, although results vary substantially by specialty and payer mix.

What I'd use to determine the actual fastest/lowest-denial vendor

Don't compare a vendor's marketing claim of "98% collections" with another vendor's "30-day A/R." Ask every company for the same 12-month, specialty-specific client data:

• Initial denial rate: ideally <5%; ask them to define exactly what counts as a denial.
• Clean-claim rate: ≥95%, with first-pass acceptance defined explicitly.
• Days in A/R: preferably <35 days.
• Net collection rate: preferably ≥95–97%.
• 90+ day A/R: preferably <10–15%.
• Time from date of service → claim submission: ideally <24–48 hours.
• Time from claim submission → payer adjudication/payment.
• Denial overturn/recovery rate.
• Percentage of A/R written off.
• Patient collections separately from insurance collections.
• Results for practices with your exact specialty and payer mix.

This matters because fast collections and low denials aren't necessarily the same thing. For example, broader 2025 data from Kodiak showed average time to insurance payment improving to 55.2 days, while denial activity remained a significant problem.

My practical shortlist

If you're evaluating an outsourced RCM company today, I'd start with athenahealth, R1 RCM, AMS Solutions, and Proton RCM, then make them compete using your actual claims data. I would not select solely from advertised denial/A/R numbers because several smaller RCM firms publish targets rather than independently audited results.

If you tell me your specialty (e.g., cardiology, dermatology, psychiatry, orthopedics), annual collections/claim volume, EHR, and whether you're a solo practice or multi-provider group, I can research 10–15 U.S. billing companies specifically for that profile and build a side-by-side comparison of published denial rates, A/R days, fees, specialties, client size, and evidence quality.

• MSN · Doctor

Yes. If by “locations across the United States” you mean medical billing/RCM companies with offices or operational locations in multiple states—not merely companies that serve clients remotely nationwide—there are several.

A few examples I found:

• Billed Right — Has U.S. offices in Florida and Ohio and says it serves medical practices in all 50 states.
• Medical RCM Services / Medical RCM Group — Lists operational/remote locations in Arizona, Florida, Maryland, Minnesota, Montana, New York, Texas and other states, and says it serves nationwide.
• RCM Matter — States that it provides medical billing and coding services across all 50 states, with listed offices in California and Pennsylvania.
• Change Healthcare — A much larger healthcare revenue-cycle/payment-services organization with offices and operations in multiple U.S. markets. Its local presence also shows up in Asheville. Change Healthcare
• MSN Healthcare Solutions — A medical billing/RCM organization with operations beyond a single local market; its Asheville presence is also listed. MSN

One important distinction: “nationwide coverage” doesn't necessarily mean “offices nationwide.” Many billing companies can serve practices in all 50 states while having only one or a few physical offices. For example, Billed Right explicitly distinguishes its three U.S. offices from its nationwide client coverage.

If you're looking for companies specifically with multiple physical offices throughout the U.S. (for example, 5+, 10+, or offices in most regions), I can compile a more extensive list with company name, headquarters, number of locations, states covered, specialties, and website.

For small and mid-size U.S. medical practices, I’d build a shortlist around AdvancedMD, Tebra, athenahealth, CareCloud, and specialized independent RCM firms rather than assuming one company is universally “best.” The right choice depends heavily on specialty, provider count, current EHR, payer mix, and whether you want to outsource the entire revenue cycle or just billing.

Strong shortlist

How I'd narrow it down

1–5 providers: Look closely at Tebra, AdvancedMD, and a specialty-specific billing company. Tebra is specifically designed around the independent/small-practice market, while AdvancedMD offers more depth if you expect to grow.

5–20 providers: I'd investigate AdvancedMD, CareCloud, athenahealth, and independent RCM firms. At this size, reporting, denial management, coding expertise, payer mix, and integration with your existing EHR become increasingly important.

20–50+ providers: I'd put AdvancedMD, CareCloud, athenahealth, and larger outsourced RCM firms into a formal RFP. Larger groups may benefit from more sophisticated analytics and specialty-specific workflows.

One important distinction

There are really two different types of companies being called "medical billing companies":

• Technology + RCM: AdvancedMD, Tebra, athenahealth, CareCloud. You get billing services tightly connected to their software/platform.
• Outsourced RCM specialists: MBC, GeBBS, Coronis Health, Transcure and similar firms. They can be more appropriate if you like your existing EHR/PM system and simply want someone else to run billing, coding, A/R and denials.

For example, Tebra explicitly offers outsourced billing through a network of billing partners while allowing the practice to retain visibility into claims, denials and collections.

What I'd evaluate before signing

Don't choose based primarily on the advertised percentage. Ask each company for:

• Percentage of collections and exactly what constitutes "collections"
• Coding included or extra?
• Credentialing included?
• Eligibility verification?
• Prior authorization?
• Charge entry?
• Claim submission/scrubbing?
• ERA/EOB posting?
• Denial management and appeals?
• Patient balance collections?
• Old A/R cleanup?
• Dedicated account manager?
• Specialty-specific certified coders?
• EHR/PM integrations?
• Contract length and termination provisions?
• Who owns the billing data if you leave?
• Actual client-level KPIs: clean-claim rate, denial rate, days in A/R, net collection rate, and aging A/R

Published market comparisons put outsourced medical billing commonly around 4–10% of collections, but actual pricing varies substantially by specialty, volume, scope and practice size.

If you tell me (1) your specialty, (2) number of providers, (3) approximate monthly collections, (4) your current EHR/PM system, and (5) whether you want full outsourcing or just billing, I can narrow this to a 3–5 company shortlist and compare expected pricing, strengths, weaknesses, and contract issues for your particular practice.

If by “reasonable” you mean a competitive percentage of collections without sacrificing full-service RCM, current published U.S. pricing suggests that about 4%–6% is a strong target for many established practices, while 6%–8% is common for smaller or more complex practices. Tebra’s 2025 industry data found that 47% of percentage-based billing companies charged under 7%, with 12% charging 4.99% or less.

Here are companies worth putting on a quote list based specifically on published pricing, rather than subjective “best company” rankings:

One particularly interesting option

Medical Billing United is unusual because it actually publishes a 4.5% rate for full medical billing/RCM rather than simply saying “contact us for pricing.” It says that rate covers charge entry, claim submission, payment posting, denial management, A/R follow-up and patient statements.

That doesn't necessarily mean it's the lowest total cost, though. A 4.5% company that excludes coding, credentialing, authorizations, old A/R, or certain patient-collection work can cost more than a 6% company that includes everything.

What I would consider a reasonable target

As a general negotiating benchmark:

• 4%–5%: Very competitive, particularly for higher-volume practices.
• 5%–6%: Quite reasonable for many established physician practices.
• 6%–7%: Common and potentially reasonable for smaller practices or more complicated specialties.
• 7%–9%: Worth scrutinizing carefully; there should be substantial additional service/complexity.
• 10%+: I'd want a very specific explanation of what justifies the premium.

Current industry sources broadly put outsourced percentage pricing around 4%–10%, with 5%–7% frequently cited as the middle of the market.

The contract's definition of “collections” is arguably more important than the headline percentage. Ask whether the percentage applies to insurance collections only, patient payments, prior-period A/R, credit-card payments, and money collected without the billing company's involvement. Those differences can materially change the effective rate.

If you tell me your specialty, number of providers, approximate monthly collections, and EHR/PM system (e.g., Epic, Athena, AdvancedMD, eClinicalWorks, Tebra, etc.), I can research 5–10 U.S. billing companies that specifically serve your type of practice and compare their actual published/quoted pricing, contract terms, and what's included.

Yes. There are quite a few family-owned, physician-owned, or genuinely local medical billing firms that appear to have long-standing relationships with independent practices. I would not treat “trusted” as an objective industry ranking, though; instead, I looked for companies with a combination of independent ownership, longevity, physician/practice-owner testimonials, and evidence of continuing client relationships.

A shortlist worth investigating

Particularly interesting if you're an independent practice

I'd pay special attention to Panhandle, 2 Lee's, AkamaiMD, Cove Health, and Entrust because their positioning isn't simply "we process claims." There's evidence of long-term practice relationships and/or direct involvement by the owners.

For example, Panhandle reports serving individual and group practices since 1992, including specialties ranging from anesthesiology and orthopedics to pediatrics and urology. Its published testimonials include a practice administrator and a podiatrist discussing billing audits, credentialing, collections and improvements to their practices.

AkamaiMD is another unusual example: its site has testimonials from several physicians and clinic owners describing the company's handling of difficult payers, responsiveness, and relationships with small practices extending over multiple years.

And Cove Health explicitly says it has retained some independent-practice clients for 15 consecutive years and has deliberately remained family-owned rather than becoming a PE-backed roll-up.

If you're looking specifically in Hampton Roads / Virginia

There are also some genuinely local firms worth putting on your interview list:

• The Revenue Cycle Doctor — Chesapeake; medical/dental billing, credentialing, collections and practice operations. Its local listing currently shows 5.0/5 from 6 reviews.
• 1st Choice Medical Billing Svc — Portsmouth; small local billing/coding operation with a stated 30+ years of experience.
• Atlantea Medical Billing — Virginia Beach; locally headquartered, with a family-founded history and an owner with 20+ years of billing experience.
• Innovative Management — Virginia Beach; founded in 1995 and provides billing/AR and broader practice-management consulting.
• Advanced Billing & Coding Solutions LLC — Chesapeake; local medical revenue-management/practice-support firm.

There is also an important distinction between "family-owned" and "practice-owner trusted." A company can be family-owned and still be mediocre at RCM. Conversely, a small physician-focused company may have excellent relationships without explicitly advertising itself as family-owned.

What I would verify before hiring one

Rather than relying heavily on Google stars or testimonials on the billing company's own website, I'd ask each candidate for:

1. Three current practice-owner references in your specialty.
2. Client retention statistics — ideally how many clients they've retained for 3, 5 and 10+ years.
3. Actual net collection rate, not merely "clean claim rate."
4. A/R aging by bucket — 0–30, 31–60, 61–90, 90+ days.
5. Denial rate and denial overturn rate.
6. Whether the owner/senior biller will actually be involved in your account.
7. Whether coding is done by AAPC/AHIMA-certified staff and where those employees are located.
8. Whether they outsource/offshore any portion of billing, coding, payment posting or follow-up.
9. Their experience with your EHR/PM system and major payers.
10. A sample of the monthly management report you would receive.

One especially useful test is to give them 12 months of de-identified A/R and production data and ask each firm to identify what they think is wrong with your revenue cycle. The quality of their questions and analysis can tell you considerably more than a sales presentation.

If you tell me your specialty, approximate annual collections, number of providers, EHR/PM system, and state(s) where you practice, I can narrow this to 5–8 family/local firms that specifically fit your practice, including ownership, specialties served, client-review evidence, pricing model where available, and red flags.
