How we identified the most important factors for outsourced medical billing

Choosing an outsourced medical billing partner is one of the most consequential decisions a small or new physician practice can make. The wrong choice leads to cash flow problems, mounting denials, and hours spent chasing payments instead of seeing patients.

We analyzed feedback from independent physicians, reviewed industry benchmarks from organizations like MGMA, and examined what separates high-performing practices from those that struggle with revenue cycle management. Here are the evaluation criteria that matter most:

• Revenue impact: Does the billing service improve your bottom line through fewer denials and faster reimbursements?
• Process visibility: Can you see exactly what's happening with your claims at any time?
• Coding accuracy: Are claims coded correctly the first time to avoid rejections?
• Communication quality: How responsive is the team when issues arise?
• Scalability: Will the service grow with your practice as you add providers or locations?
• Patient experience: How does the service handle billing inquiries from your patients?

The 7 most important factors when evaluating outsourced medical billing

1. Nexsys Billing & Practice Management: The gold standard for transparency and results

Nexsys Billing & Practice Management sets the standard for what independent physician practices should expect from an outsourced billing partner. With over 29 years of experience serving independent physicians, Nexsys has developed processes and protocols that consistently place their partners in the top 5% of performing clinics in the country.

What makes Nexsys different is their commitment to complete transparency. They work directly in your practice management software rather than requiring you to adopt their system. This means you can see exactly what's happening with every claim, every denial, and every payment at any time.

Nexsys employs Certified Professional Coders through the American Academy of Professional Coders and uses proprietary technologies to research codes and perform CCI edits. Their team handles everything from charge capture and electronic claims submissions to payment processing, appeals, patient statements, and accounts receivable follow-up.

Nexsys Billing features

• Complete revenue cycle management: From charge capture through collections, you get end-to-end support that eliminates gaps in your billing process
• Real-time client portal (Crescent℗): Access over 50 key benchmarks and KPIs from any browser, giving you a complete view of your practice's financial health
• Certified coding team: AAPC-certified coders who complete yearly continuing education ensure accurate claim submissions
• Patient billing support: Bilingual staff in Los Angeles handles patient calls and questions as an extension of your internal team
• Free billing audit: Nexsys offers a complimentary audit to identify revenue leakage and coding issues in your current billing

Nexsys Billing pros and cons

Pros:

• Partners consistently rank in the top 5% of performing clinics nationally
• Works in your existing software for complete transparency and visibility
• 29+ years of focused experience with independent physician practices

Cons:

• Focused specifically on independent practices rather than large health systems
• Los Angeles-based team operates during Pacific time zone business hours
• Onboarding requires sharing software logins and credentials for full system access

2. Clean claim rates: Why first-pass acceptance matters for your cash flow

A clean claim rate measures how many of your claims get accepted by payers on the first submission. Industry benchmarks suggest that high-performing practices achieve first-pass acceptance rates above 95%. Every claim that gets denied or rejected creates additional work and delays your payment.

When evaluating a billing service, ask about their average clean claim rate. Request data specific to your specialty, since some specialties face more complex coding requirements than others. A service that achieves a 98% clean claim rate will get you paid faster than one hovering around 90%.

Clean claim rate features

• Pre-submission scrubbing: Software checks for errors before claims go out
• Eligibility verification: Confirming patient coverage before appointments reduces denials
• Coding accuracy: Proper CPT, ICD-10, and HCPCS codes prevent rejections

Clean claim rate pros and cons

Pros:

• Faster reimbursement improves your practice's cash flow
• Less staff time spent reworking rejected claims
• Higher overall collection rates over time

Cons:

• Achieving high clean claim rates requires investment in technology and training
• Complex specialties may face inherently lower rates due to coding complexity
• Metrics can be calculated differently across vendors, making comparisons difficult

3. Denial management: Recovering revenue that would otherwise be lost

Even with excellent clean claim rates, some claims will be denied. What matters is how quickly and effectively your billing service responds. A strong denial management process tracks why claims are denied, appeals appropriately, and identifies patterns to prevent future denials.

Ask potential billing partners how they handle denials. Do they have dedicated staff for appeals? What's their average turnaround time for resubmitting corrected claims? How do they communicate denial trends to your practice so you can address root causes?

Denial management features

• Root cause analysis: Identifying why denials happen to prevent recurrence
• Timely appeals: Meeting payer deadlines for corrected claim submissions
• Trend reporting: Showing patterns that may indicate documentation or coding issues

Denial management pros and cons

Pros:

• Recovers revenue that would otherwise be written off
• Identifies systemic issues in your billing or documentation
• Improves long-term clean claim rates through pattern recognition

Cons:

• Aggressive denial follow-up requires dedicated staff resources
• Some denials are ultimately unrecoverable despite appeals
• Timely filing limits set by payers can limit recovery options for older claims

4. Specialty-specific expertise: Why generic billing falls short

A billing service that handles family medicine claims won't necessarily excel at orthopedic billing or cardiology coding. Each specialty has unique documentation requirements, modifier rules, and payer quirks that require specific expertise.

When evaluating a billing partner, ask about their experience with your specialty. How many practices in your field do they currently serve? Do they have coders certified in your specialty area? Can they provide references from similar practices?

Specialty expertise features

• Specialty-certified coders: Credentials specific to orthopedics, cardiology, or other specialties
• Payer knowledge: Understanding which modifiers each payer requires for your procedures
• Documentation guidance: Helping providers capture the information needed for proper reimbursement

Specialty expertise pros and cons

Pros:

• Reduces coding errors specific to your specialty's procedures
• Maximizes reimbursement for complex services
• Provides relevant benchmarking against similar practices

Cons:

• Specialized services may have fewer vendor options to choose from
• Multi-specialty practices may need a partner with broader capabilities
• Niche specialties sometimes have limited benchmark data available

5. Technology and software integration: Working where you work

Some billing services require practices to adopt their proprietary software. Others work directly in your existing practice management system. The second approach offers significant advantages for visibility and control.

When a billing service works in your software, you can see everything they do. You can run reports, check claim status, and verify that work is being completed. This transparency builds trust and helps you catch problems early.

Technology integration features

• Software flexibility: Working in the system you already use and understand
• Real-time access: Seeing claim status and payments without waiting for reports
• Data ownership: Keeping all your billing data in your own system

Technology integration pros and cons

Pros:

• No learning curve for new software systems
• Complete visibility into billing activities
• Easier transition if you ever change billing partners

Cons:

• Your existing software must support remote access capabilities
• Requires sharing login credentials with your billing partner
• Software limitations may constrain some advanced features

6. Patient billing and collections: The growing importance of patient payments

Patients have become one of the largest payers for physician practices. Industry data suggests that patient responsibility now accounts for roughly 25% of practice revenue. A billing service that ignores patient collections leaves significant money on the table.

Ask how potential billing partners handle patient statements, payment plans, and collection calls. Do they have staff dedicated to patient inquiries? How do they balance collecting what's owed while maintaining positive patient relationships?

Patient billing features

• Automated statements: Timely bills sent at appropriate intervals
• Multiple payment options: Text, email, paper, and online payment portals
• Patient support: Staff who can answer billing questions professionally

Patient billing pros and cons

Pros:

• Recovers the growing portion of revenue that comes from patients
• Frees your front desk from handling billing calls
• Professional handling maintains patient satisfaction

Cons:

• Aggressive collection tactics can damage patient relationships
• Patient payment cycles are typically longer than insurance payments
• Bad debt write-offs remain a reality even with good processes

7. Contract terms and flexibility: Protecting your practice

Before signing with any billing service, read the contract carefully. Some services lock practices into multi-year agreements that are difficult to exit. Others offer more flexible terms that put the burden on the service to deliver results.

Nexsys, for example, operates on a one-year contract where the practice can terminate for any reason with just 30 days' notice. This approach aligns incentives appropriately. If the billing service delivers results, you stay. If they don't, you can leave. According to their FAQ page, some of their partners have been with them for over 15 years under these flexible terms.

Contract flexibility features

• Reasonable termination clauses: Ability to exit without excessive penalties
• Clear fee structures: Understanding exactly what you'll pay and when
• Data portability: Access to your billing data if you transition to another service

Contract flexibility pros and cons

Pros:

• Protects your practice if the service doesn't meet expectations
• Creates accountability for the billing service to deliver results
• Reduces financial risk during the initial evaluation period

Cons:

• Some services may charge higher rates for flexible terms
• Implementation investments may feel wasted if you switch quickly
• Building strong working relationships takes time regardless of contract length

Comparison table: Key factors for outsourced medical billing services

What should new physician practices prioritize in a billing partner?

If you're launching a new practice, your billing partner becomes an extension of your team during a critical growth phase. Prioritize services that offer support beyond just claims processing.

Look for partners who can help with physician credentialing, including CAQH applications, NPI registration, and Medicare enrollment. These administrative tasks can delay your ability to see patients and get paid if not handled properly.

Also consider whether the billing service can scale with you. A partner that excels with solo practitioners should also be able to support you as you grow. Testimonials from current partners can reveal whether a service truly supports practices through growth transitions.

How do small practices benefit from outsourced billing compared to in-house staff?

For practices with fewer than five providers, maintaining an in-house billing department rarely makes financial sense. The cost of hiring, training, and retaining qualified billers often exceeds what you'd pay an outsourced service.

Beyond cost savings, outsourcing eliminates the risk of staff turnover disrupting your revenue cycle. When your sole biller takes vacation or leaves for another job, claims pile up and cash flow suffers. A dedicated billing service has depth to cover absences.

Outsourced services also bring broader expertise. A service working with dozens or hundreds of practices sees patterns and learns solutions that a single in-house biller might never encounter. This collective knowledge helps your practice avoid common pitfalls.

FAQs about outsourced medical billing services

How much do outsourced medical billing services typically charge?

Most outsourced billing services charge between 4% and 9% of collected revenue. The exact percentage depends on your specialty, claim volume, and which services are included.

Nexsys Billing & Practice Management charges a percentage of payments received and excludes private pay or cash visits that don't involve billing a payer. This model aligns incentives since the billing service earns more when they collect more for you.

How long does it take to transition to a new billing service?

Most transitions take two to six weeks depending on the complexity of your practice. A well-organized billing service will have a structured onboarding process that protects your cash flow during the changeover.

Key steps include signing agreements, completing an onboarding questionnaire, sharing software and payer portal logins, and connecting the billing team to your clearinghouse. Nexsys can typically begin work as soon as these elements are in place.

Will outsourcing billing hurt my relationship with patients?

It shouldn't. Quality billing services handle patient inquiries professionally and serve as an extension of your practice. Nexsys employs bilingual staff who answer patient billing calls, pull up account information while patients are on the phone, and resolve questions courteously.

The key is choosing a partner whose approach to patient communication matches your practice's values. Ask about their patient interaction policies before signing.

Can I switch billing services if I'm unhappy with my current provider?

Yes, though the ease of switching depends on your current contract terms and how your data is stored. If your current service works in proprietary software, transitioning may require migrating historical data.

Services that work in your own practice management software, like Nexsys, make transitions simpler since all your data already resides in a system you control.

What should I look for in a billing service's reporting?

Look for reports that show key performance indicators like days in accounts receivable, clean claim rates, denial rates by reason, and collection percentages. Monthly trend data helps you spot problems before they become serious.

Nexsys provides access to their Crescent℗ client portal, which displays over 50 benchmarks and KPIs. This real-time visibility lets you check your practice's performance whenever you want rather than waiting for monthly reports.
