If you run a small practice, billing eats time you should spend on patients. A single biller out sick, a missed eligibility check, or a stack of unworked denials can stall cash flow for weeks. That is why more owners now look at medical billing services for small practices instead of hiring and training in-house staff.
The short answer: the best service for you depends on your specialty, your EHR, and how the company charges. Most price at 4% to 9% of collections, though some add setup or per-claim fees. Look for a clean claim rate above 95%, real denial follow-up, and reporting you can read without a consultant.
Below, you will find seven billing companies compared on pricing, features, and fit for small practices. We cover what each does well and where it falls short. We also include InfiniteRCM, which we run, so you know where we stand. Whether you search broadly or want medical billing services for small practices near me, use this list to build a shortlist and ask better questions on your first call.
1. InfiniteRCM
What they offer
InfiniteRCM is our company, so read this entry with that in mind. We cover the full revenue cycle for small and mid-size practices, from the front desk to the final payment posted. The core services are:
- Eligibility verification, clean claim submission, payment posting, and denial management
- AR recovery, including unpaid claims, underpayments, and insurance appeals
- Credentialing and enrollment, CAQH profile upkeep, and NPI registration support
- Prior authorization, from requirement checks to payer follow-up
- Medical virtual assistants for scheduling, insurance verification, and admin work
Our results across 500+ providers include a 99% clean claim rate, 40% faster collections, and 60% fewer denials. We have recovered over $50M for clients. Everything runs on cloud-based tools that connect to your existing EHR or practice management system, with real-time dashboards and 24/7 support.
A billing partner earns its fee through denials prevented, not just claims sent.
Pricing
We do not publish a flat rate, because cost depends on your specialty, claim volume, and which services you add. What we do promise is transparent pricing with no hidden fees. You get a written quote that spells out what is included before you sign. Compare it against the 4% to 9% range mentioned earlier, and ask every vendor, us included, about setup and add-on charges.
Best for
Practices that want one partner instead of three will get the most from us. If you are a family medicine, cardiology, or orthopedic clinic with high denial rates or long AR days, our denial and AR teams fit well. We also suit groups that need credentialing, prior auth, or virtual staff alongside billing, since you avoid juggling separate contracts.
Limitations to consider
No vendor fits everyone, and we are no exception. Our model is remote and cloud-based, so you will not get a biller who walks into your office. Pricing is quote-based, which means you must request numbers instead of reading them off a website. And if you only want basic claim submission at the lowest possible rate, a narrower, bare-bones vendor may cost less than our broader service.
2. AnnexMed
What they offer
AnnexMed is a medical billing company that provides end-to-end billing for practices across many specialties. Based on its published service pages, the core offering includes:
- Charge entry, claim submission, and payment posting
- Denial follow-up and accounts receivable management
- Medical coding and credentialing support
Confirm the exact scope on your first call, because service bundles can differ from one contract to the next.
Pricing
AnnexMed does not publish its rates, so expect a custom quote based on specialty and claim volume. Billing firms in this category usually charge a percentage of collections, so measure any offer against the 4% to 9% range covered earlier.
Quotes only compare fairly when every vendor prices the same scope of work.
Ask whether coding, credentialing, and old AR cleanup sit inside the percentage or bill separately. Get the answer in writing before you sign.
Best for
Small practices that want a dedicated billing team and are comfortable with a standard outsourced model are the natural fit. If your needs are mostly claims, denials, and AR, you will likely use most of what they sell.
Groups with tidy front-desk workflows benefit most, since clean intake data gives any biller a better shot at first-pass payment.
Limitations to consider
Public detail on technology, reporting, and results is thin, so ask for sample reports and references from practices in your specialty. Do not rely on marketing claims alone.
Compared with a full-service partner, you may also need separate vendors for prior authorization or virtual staff, which means more contracts to manage.
3. Medmax Technologies
What they offer
Medmax Technologies sells outsourced medical billing and revenue cycle support to independent practices. Its public materials point to a service mix that typically includes:
- Claim scrubbing and electronic submission
- Payment posting and denial follow-up
- Follow-up on aging accounts receivable
- Coding and credentialing help
Scope varies by contract, so confirm what is bundled and what is billed separately before you compare Medmax with the other vendors on this list.
Pricing
Medmax does not post public rates, so you will need a custom quote. Expect a percentage-of-collections model, and test any offer against the 4% to 9% range covered earlier.
A low percentage means little if the contract leaves out the work that actually recovers money.
Ask about minimum monthly fees, setup charges, and whether appeal work carries an extra cost. Get every answer in writing.
Best for
Practices with steady claim volume and a standard specialty mix suit this kind of vendor. If your goal is to offload day-to-day claim work, you will likely use most of what Medmax sells.
Owners who already run a stable EHR should also do well, because clean charge and demographic data gives any biller a better shot at first-pass payment.
Limitations to consider
Independent reviews and published performance data are limited, so ask for references from practices of your size and specialty. Request a sample report that shows your denial rate and days in AR.
Also check whether you get a named account manager and what support hours apply. Without both, unanswered issues can sit for days while claims age.
4. Quadax
What they offer
Quadax is an established revenue cycle company that mainly serves hospitals, health systems, and larger physician groups. Its public materials describe a technology-heavy stack:
- Claims management and clearinghouse services
- Denial management and payment posting
- Patient billing and statements
- Payment processing and lockbox services
The draw here is scale and automation, which suits organizations pushing high claim volume through standard workflows.
Pricing
Quadax does not publish its rates, so you will need a custom quote. Pricing likely shifts with your service mix, so measure any percentage against the 4% to 9% range covered earlier.
Enterprise tools only pay off when your claim volume is large enough to use them.
Ask whether clearinghouse, statement, and lockbox fees are bundled or itemized. Itemized charges add up fast for a small practice.
Best for
Multi-location groups and fast-growing clinics with steady, high claim volume fit best. If you already work with hospital systems or need advanced payment processing, the platform gives you room to grow.
Limitations to consider
Small practices are not the core audience, so expect a less personal setup than at a boutique vendor. Ask about minimum volume requirements and whether you get a named account contact.
The breadth can also mean paying for tools you never touch. Request a scope that lists only the services you will actually use.
5. Capline Healthcare Management
What they offer
Capline Healthcare Management provides outsourced medical billing and revenue cycle support for independent practices. Based on its public descriptions, the service set looks fairly standard:
- Eligibility checks and claim submission
- Payment posting and denial follow-up
- Follow-up on aging accounts receivable
- Coding and credentialing assistance
Scope can shift from one contract to the next, so confirm what is included line by line before you compare Capline with other vendors.
Pricing
Capline does not publish its rates, so plan on a custom quote. Vendors in this tier usually charge a percentage of collections, so test any offer against the 4% to 9% range covered earlier.
The cheapest percentage is rarely the cheapest contract once add-on fees arrive.
Ask about setup fees, minimum monthly charges, and whether appeals and old AR cleanup cost extra. Get the answers in writing.
Best for
Practices that want a hands-off billing arrangement with a standard workflow tend to fit best. If your needs center on claims, denials, and AR, you will probably use most of what Capline sells.
Solo providers and small groups with a stable EHR and clean intake data also give any biller a better chance at first-pass payment.
Limitations to consider
Independent reviews and published performance data are limited, so ask for references from practices of your size and specialty. Request a sample report that shows your denial rate and days in AR.
Beyond billing, you may need other vendors for prior authorization or virtual staff. That means more contracts to manage and more hand-offs to track.
6. OmniMD
What they offer
OmniMD is a healthcare technology company that pairs medical billing with its own EHR and practice management software. Based on its public materials, the offering includes:
- Claim submission, payment posting, and denial follow-up
- Eligibility checks and accounts receivable follow-up
- Coding support
- Telehealth and patient engagement tools
The pitch is one connected platform for charting and billing, which means fewer hand-offs between systems and fewer places for data to break.
Pricing
Rates for billing are not published, so expect a custom quote. Software-led vendors often price the platform per provider each month, then add billing as a percentage of collections. Check any offer against the 4% to 9% range covered earlier.
A bundled price only helps if you would have bought every piece of the bundle.
Ask whether you can buy billing alone, and what it costs to leave the platform later. Get both answers in writing.
Best for
Practices ready to replace their EHR, or clinics starting fresh, get the most from this model. One vendor for charting and claims gives you cleaner data from visit to claim, plus a single support line when something goes wrong.
Limitations to consider
Keeping your current EHR may be harder, since the strongest value comes from using the whole platform. Confirm integration with your existing system before you commit, and weigh the cost of retraining your staff.
Public results data is also thin, so request references and sample reports from practices your size and specialty. Look for denial rate and days in AR.
7. Medwave Billing
What they offer
Medwave Billing is an outsourced billing company that works with independent and small practices. Based on its public descriptions, the service set covers:
- Claim submission and payment posting
- Denial follow-up and appeals
- Eligibility checks and AR follow-up
- Coding and credentialing help
Because scope differs from one contract to the next, confirm the exact scope and get it line by line in writing before you compare Medwave with the other vendors here.
Pricing
Medwave does not publish its rates, so request a custom quote. Expect a percentage of collections, and test any offer against the 4% to 9% range covered earlier.
Ask about setup fees, minimum monthly charges, and whether appeals or old AR cleanup cost extra. Put every answer in writing.
Best for
Solo providers and small groups that want a straightforward outsourced setup are the natural fit. If your needs center on claims, denials, and AR, and you run a stable EHR, you will likely use most of what Medwave sells.
Limitations to consider
Published performance data is limited, so ask for references from practices of your size and specialty. Request a sample report that shows your denial rate and days in AR.
A billing vendor is only a bargain if it can show you its numbers.
Beyond billing, you may need separate vendors for prior authorization or virtual staff. That means more contracts to manage and more hand-offs to track.
How to choose a billing service and what it costs
What billing services cost
Pricing for medical billing services for small practices usually follows one of three models. Know which one you are being quoted before you compare numbers.
| Model | Typical range | Watch for |
|---|---|---|
| Percentage of collections | 4% to 9% | Extra fees for appeals and AR cleanup |
| Flat monthly fee | Varies by provider count | Caps on claim volume |
| Per-claim fee | Varies by claim volume | Charges for resubmissions |
Percentage models tie the vendor’s pay to yours, since they earn only when you collect. But setup fees and minimum monthly charges can raise the real cost, so ask for the total over 12 months.
Compare the total cost over a year, not the headline percentage.
How to compare vendors
Start with fit, then verify the numbers. Put these questions to every vendor on your shortlist, including us:
- Does it connect to your EHR or practice management system?
- Can it report clean claim rate, denial rate, and days in AR?
- Who is your named contact, and what are the support hours?
- Can you leave with 30 to 60 days’ notice and keep your data?
- Does it have experience in your specialty?
Finally, ask for two references from practices your size. A vendor that hesitates to share them or a sample report has told you something useful.
Choosing the right billing partner
Every vendor on this list can send claims. The difference shows up in denial follow-up, reporting, and fit with your specialty. A quoted rate inside the 4% to 9% range means little until you add up setup fees, minimums, and extras over a full 12 months.
Your next step is simple. Pick two or three vendors, ask each the same questions, and request references and a sample report before you sign. Good medical billing services for small practices answer without hesitation. The vendors that stall have told you what you need to know.
If you want one partner for billing, AR recovery, credentialing, and prior authorization, request a written quote from InfiniteRCM. You will see exactly what is included and can hold it up against any other offer on your shortlist.
