Choosing a medical billing company is one of the most consequential vendor decisions a healthcare practice makes. The right partner can increase collections by 10-15%, reduce claim denials, and free your staff to focus on patient care. The wrong one can cost you thousands in lost revenue and months of administrative headaches.
Yet most practices make this decision based on a Google search, a referral from a colleague, or a cold sales call. They evaluate billing companies the same way regardless of whether they run a solo therapy practice, a multi-location dental group, or a home health agency — even though the billing requirements for each are fundamentally different.
This guide provides a structured framework for evaluating billing companies based on what actually matters: specialty expertise, service depth, pricing transparency, technology compatibility, and verifiable trust signals. Every recommendation is grounded in our analysis of 273 billing companies across 5 healthcare specialties.
Most billing companies are niche-focused. Choosing one with proven expertise in your specialty is critical.
Why Specialty Experience Is the Most Important Factor
Medical billing is not a one-size-fits-all service. The codes, payer rules, authorization workflows, and compliance requirements differ dramatically by specialty. A billing company that excels at dental claims may have no idea how to handle ABA therapy authorizations or home health OASIS documentation.
| Specialty | Code System | Key Complexity |
|---|---|---|
| Mental Health | CPT 90834, 90837, 90847, E/M | Time-based coding, telehealth modifiers, parity laws |
| ABA Therapy | CPT 97151-97158 | State Medicaid variations, ongoing authorization tracking |
| Dental | CDT codes (D0000-D9999) | Pre-determination, coordination of benefits, DSO billing |
| Physical Therapy | CPT 97110-97542, modifiers | 8-minute rule, therapy caps, functional limitation reporting |
| Home Health | HCPCS, ICD-10, OASIS | PDGM, face-to-face documentation, Medicare compliance |
When a billing company lacks specialty expertise, the consequences are measurable: higher denial rates, slower reimbursement, incorrect coding that triggers audits, and missed revenue from services that were never billed correctly. These are not theoretical risks — they are the most common complaints practices report when switching away from a generalist billing company.
The 7 Factors That Matter Most
Based on our analysis of 273 billing companies and the data points that most reliably distinguish strong specialty partners from generalists, these are the seven evaluation criteria that matter most.
1Specialty Depth
Look for companies that have dedicated pages for your specialty on their website, use specialty-specific terminology, and can demonstrate experience with your specialty's unique billing codes. In our directory, we evaluate this through "Specialty Evidence" — whether a company has verifiable, public-facing content about serving your specialty, not just a checkbox on a form.
2Service Breadth
Beyond basic claims submission, evaluate whether the company offers the full range of services your practice needs. The most commonly offered services in our directory are:
Note that only 34% of companies offer prior authorization support — a critical service for ABA and home health practices. If your specialty requires frequent authorizations, this should be a non-negotiable requirement.
3Geographic Coverage
Determine whether you need a company with nationwide coverage or one that specializes in your state's payer landscape. In our directory, 63% of companies offer nationwide service. However, for specialties with significant state-level variation (like ABA therapy, where Medicaid rules differ by state), a company with deep knowledge of your state's specific requirements may be more valuable than one with broad but shallow coverage.
4Pricing Transparency
Only about 30% of billing companies in our directory publicly disclose their pricing model. The most common models are percentage of collections (typically 4-9%), flat monthly fees, and hybrid arrangements. A company that is transparent about pricing before the sales call is generally a positive signal. Read our detailed pricing models guide for a full comparison.
5Technology Compatibility
Your billing company must integrate with your existing EHR or practice management system. The most commonly supported platforms in our directory are Kareo/Tebra, AdvancedMD, eClinicalWorks, athenahealth, and specialty-specific systems like TherapyNotes (mental health), WebPT (physical therapy), CentralReach (ABA), and Open Dental/Dentrix (dental). If your billing company requires you to switch systems, factor that migration cost into your evaluation.
6Trust Signals
Look for verifiable indicators of credibility: client testimonials (73% of companies in our directory have them), case studies (21%), years in business, professional certifications, and an active LinkedIn presence. Be cautious of companies that make bold claims about collection rates without providing verifiable evidence.
7Client Fit
A billing company that serves enterprise health systems may not be the right fit for a solo practitioner, and vice versa. Evaluate whether the company's typical client size matches your practice. Some companies specialize in solo and small group practices, while others focus on multi-location organizations and DSOs.
How to Evaluate by Specialty
Beyond the universal factors above, each specialty has unique evaluation criteria. Here is what to prioritize for each.
Mental Health / Behavioral Health
- Experience with time-based CPT codes (90834, 90837) and psychotherapy add-on codes
- Telehealth billing expertise (modifier 95 vs. GT, POS code differences)
- Insurance panel credentialing and CAQH profile management
ABA Therapy
- Mastery of CPT 97151-97158 and state-specific Medicaid billing rules
- Proactive authorization tracking and renewal management
- Integration with ABA-specific platforms (CentralReach, AlohaABA)
Dental
- CDT code expertise and dental-specific payer knowledge
- Pre-determination and coordination of benefits handling
- DSO/multi-location support if applicable (30 companies in our directory)
Physical Therapy
- Understanding of the 8-minute rule and timed/untimed code distinctions
- Experience with therapy cap tracking and exceptions
- Integration with PT-specific platforms (WebPT, Clinicient)
Home Health
- PDGM (Patient-Driven Groupings Model) expertise for Medicare billing
- OASIS documentation support and face-to-face encounter compliance
- Integration with home health EMRs (Kinnser, Axxess, WellSky, MatrixCare)
Red Flags to Watch For
During your evaluation, watch for these warning signs that a billing company may not be the right fit.
Generic website with no specialty-specific content
If a company claims to serve your specialty but has no dedicated page, case study, or specific mention of your specialty's codes and workflows, their expertise may be superficial.
No verifiable client references in your specialty
Ask for references from practices similar to yours. A company that cannot provide them may lack relevant experience.
Unclear or evasive pricing
While pricing varies by practice size, a company should be able to explain their pricing model clearly before you sign a contract.
No credentialing support
If your practice needs credentialing (and most do), a billing company that does not offer it will leave a gap in your revenue cycle.
Promises of specific collection rates without evidence
Be wary of companies that guarantee collection rates of 98%+ without providing verifiable case studies or client testimonials to support the claim.
Long-term contracts with no performance guarantees
A company confident in its service should not need to lock you into a multi-year contract. Look for month-to-month or 90-day termination clauses.
