Choosing a medical billing company is an important decision for any healthcare practice that wants better control over claims, payments, and accounts receivable. This guide covers private medical billing companies in the US, what they offer, who they may be a good fit for, and what to consider before signing a contract.
The demand for outsourced billing continues to grow. Grand View Research estimates that the U.S. medical billing outsourcing market was worth $6.95 billion in 2025 and could reach $17.69 billion by 2033.
Why Are Medical Billing Services in Demand?
Medical billing has become more difficult to manage as payer requirements, coding rules, claim volumes, and administrative responsibilities continue to grow. Outsourcing allows healthcare practices to bring in billing specialists without building a large internal revenue cycle team.
Claim denials are another reason practices look for outside support. Recent research has reported that around 12% of initial claims can be denied, although the rate varies depending on the payer, provider, specialty, and type of claim. For a busy practice, even a small percentage of unpaid claims can create a large amount of work.
How We Evaluated These Companies
We looked at the services each company publicly offers, including medical billing, revenue cycle management, coding, denial management, credentialing, claims processing, and related healthcare technology. We also considered the types of healthcare organizations each company says it serves.
The “Best for” descriptions are included to make the list easier to understand. They are not independent rankings or claims that one company is better than another.
Top Private Medical Billing Companies in the US
The companies below serve different parts of the healthcare market. Some focus more on independent practices, while others provide technology or revenue cycle services for larger physician groups and health systems.
Medientsky Billing
Best for: Practices looking for end-to-end revenue cycle support
Medientsky Billing provides medical billing and revenue cycle management services for healthcare providers across the US. Its services include medical billing and claims processing, medical coding, denial management, credentialing, billing audits, and EHR/EMR integration.
The company says its billing specialists support more than 30 medical specialties. Its RCM approach covers several stages of the billing process, from patient intake through payment and follow-up.
For practices dealing with recurring denials, aging A/R, or multiple billing responsibilities, having one team manage several parts of the revenue cycle can make day-to-day operations easier.
BillingParadise
Best for: Small and mid-sized practices with broader RCM needs
BillingParadise provides front-end, middle, and back-end revenue cycle services. Its offerings include eligibility verification, prior authorization, medical coding, claims submission, payment posting, denial management, A/R follow-up, and credentialing.
The company also says it works with more than 25 EHR systems and supports independent practices, group practices, and hospitals.
For a practice that wants to outsource several billing functions rather than manage separate vendors for coding, claims, and A/R, this type of service model may be worth considering.
Medwave Billing & Credentialing
Best for: Practices that need billing and credentialing support
Medwave provides medical billing and credentialing services for healthcare providers in the US. Combining these services can be useful for practices that need help with both ongoing claims and getting providers enrolled with insurance payers.
For providers searching for a medical billing company in New York, it is also worth checking whether a billing company has experience with the payers and requirements relevant to the local market.
Before choosing a company, ask which payers it regularly works with and whether credentialing is handled by the same team responsible for billing.
AdvancedMD
Best for: Independent private practices wanting billing and practice technology together
AdvancedMD offers medical billing software along with managed revenue cycle services. Its RCM services include claims management, payment posting, denial and collection support, reporting, and account management.
The company positions its services around independent physicians and private practices. It also offers EHR and practice management technology, allowing clinical, administrative, and financial workflows to work together.
This can be useful for practices that prefer an integrated system instead of moving information between several separate platforms.
athenahealth
Best for: Growing practices and organizations with more complex billing needs
athenahealth provides revenue cycle services covering areas such as registration, insurance verification, authorization management, coding, claim submission, payment posting, denial resolution, and reporting.
Its athenaIDX product is designed for larger and more complex organizations, while athenaOne combines EHR, practice management, and revenue cycle functions for other healthcare practices.
For a growing organization, the ability to support both everyday billing and more complex revenue cycle operations can be an important consideration.
R1
Best for: Health systems and large provider organizations
R1 focuses on enterprise revenue cycle management and works with health systems, physician groups, and other healthcare organizations.
Its services combine revenue cycle operations with technology, automation, analytics, and other financial management tools.
R1 is therefore a different type of option from a smaller billing company that mainly works with independent physician practices. Larger organizations considering an enterprise provider should look closely at implementation, integration, reporting, and the level of support available.
DrChrono
Best for: Independent practices looking for an integrated EHR and billing setup
DrChrono combines EHR, practice management, payments, medical billing, and revenue cycle tools in one platform. It also provides managed billing services.
Its RCM services include eligibility verification, claims submission, payment posting, denial management, and A/R follow-up. DrChrono also says its managed RCM service includes certified billers and coders and provides reporting.
For smaller practices, keeping clinical and financial workflows within one connected system can reduce the need to transfer information between different platforms.
Coronis Health
Best for: Healthcare organizations needing broader RCM support
Coronis Health provides revenue cycle services covering medical billing, coding, credentialing, collections, and other financial operations.
Its broader service model may be useful for organizations that need help across multiple parts of their revenue cycle rather than simply sending claims to insurance companies.
Larger provider groups should also look at how a company handles reporting, system integration, implementation, and communication across different locations.
eClinicalWorks
Best for: Practices looking for integrated healthcare technology
eClinicalWorks brings together electronic health records, practice management, patient engagement, and revenue cycle functions.
Its billing capabilities are designed to connect clinical documentation with the financial side of the practice. This can reduce some of the manual work involved in moving information between clinical and billing systems.
For practices already using eClinicalWorks, its integrated approach may be worth comparing with a separate medical billing service.
NextGen Healthcare
Best for: Physician groups and specialty practices
NextGen Healthcare provides EHR, practice management, and revenue cycle solutions for ambulatory healthcare organizations.
Its platform connects clinical and financial workflows, with revenue cycle capabilities covering areas such as claims, payments, and financial performance.
For physician groups that want their practice management and billing technology connected, NextGen Healthcare is another option to consider.
What Should You Ask a Medical Billing Company Before Hiring One?
A billing company should be able to clearly explain what it will handle, how it will communicate with your team, and how billing performance will be reported. Before signing an agreement, ask these questions:
- Which specialties do you regularly support?
- What happens when a claim is denied?
- How often do you work aging A/R?
- What billing and financial reports will we receive?
- Which EHR and practice management systems do you support?
- Who will be our main account contact?
- How are coding errors identified and corrected?
- How is patient billing handled?
- What are your fees and contract terms?
- How is patient information protected?
These questions can help you understand whether a company is providing complete revenue cycle support or mainly handling claim submission.
What Makes a Good Medical Billing Company?
A good billing company should do more than send claims to insurance companies. It should help the practice understand what has been billed, what has been paid, what remains outstanding, and why claims are being denied.
Specialty experience is important because billing requirements can vary considerably between different areas of healthcare. A company should also have a clear process for denial follow-up, A/R management, reporting, and communication.
Price matters, but it should not be the only factor. A lower billing fee may not be useful if claims are left unresolved or the practice has little visibility into its outstanding revenue.
