MSOs are growing rapidly, and the numbers prove it. The U.S. Management Service Organization (MSO) market was valued at about $46.78 billion in 2023 and is projected to reach over $108 billion by 2030, growing at nearly 13% annually. On the other hand, the broader healthcare MSO market is expected to grow at a CAGR of around 10.9% through 2034. The primary driving force behind it is healthcare consolidation, private equity investment, and the need for administrative efficiency across multi-practice organizations.
While MSO remains at the forefront, Revenue Cycle Management remains one of the largest and fastest-growing service segments. It has been observed that organizations increasingly outsource billing, coding, credentialing, and compliance to improve cash flow and operational efficiency. The challenge remains that each practice has its own payer mix, coding requirements, and compliance needs. And you’re trying to standardize processes while respecting practice-specific workflows. It’s enough to make anyone’s head spin.
That’s where DrCatalyst comes in. We’re not just another medical billing company. We’re the RCM partner MSOs wish they’d found sooner. Here’s why.
What Makes MSO Billing and Revenue Cycle Management Different
Before we dive into why DrCatalyst is different, let’s talk about what makes MSO revenue cycle management uniquely challenging. Unlike single practices, MSOs deal with:
- Multiple Specialties Under One Umbrella
You might be managing billing as well as RCM for primary care, cardiology, orthopedics, dermatology, and behavioral health, all with completely different coding requirements, documentation standards, and payer rules.
- Different Locations, Different Payer Mixes
Your Boston practices have totally different insurance networks from your Miami locations. What works in one state creates compliance nightmares in another.
- Various EHR Systems
Acquisition #1 uses eClinicalWorks. Acquisition #2 is on athenahealth. Acquisition #3 just implemented Epic. Your billing and revenue cycle team is supposed to work efficiently across all of them.
- Inconsistent Workflows
Each practice you’ve brought into the MSO has its own way of doing things. Standardizing without destroying what works? That’s the million-dollar question.
- Complex Compliance Requirements
Between Corporate Practice of Medicine (CPOM) laws, Stark Law, Anti-Kickback Statute, and state-specific regulations, compliance isn’t just important; it’s a make-or-break situation.
- Demand for Scalability
You’re growing through practice acquisitions. Your RCM solution needs to onboard them quickly without breaking what’s already working. Most medical billing companies on the market are designed only for single practices or small groups. They promise they can “scale” to the expansive needs of MSO, but when you actually need them to handle five new practices next quarter, their systems (and their promises) fall apart.
Why DrCatalyst is Built Different for MSOs
At DrCatalyst, we don’t just say we understand MSOs. We prove it every day with over 250+ RCM clients, many of whom operate multiple locations across different specialties. Here’s exactly how we solve the unique challenges MSOs face:
1. We Actually Work With 60+ EHR/PM Systems
Remember that multi-system nightmare we mentioned? We live in it every day, and we’ve mastered it. For MSOs, this would mean:
No forced EHR standardization across all practices
Swift billing across eClinicalWorks, athenahealth, Epic, Cerner, NextGen, AdvancedMD, and 50+ other EHR systems
If it is a new practice acquisition, we’re already trained on their system
Unified reporting across all platforms so you actually know what’s happening
While other billing companies tell you to “standardize on one EHR” (spoiler: that’s expensive and disruptive), we work with what you have. Your practices keep the systems. We make them all talk to each other on the backend.
2. Centralized Operations + Specialty-Specific Expertise
Most MSO billing solutions fail because they either centralize everything (losing specialty expertise) or keep everything decentralized (losing efficiency and consistency). DrCatalyst does both effectively. Our multi-tiered team structure, with a US-based account manager as your single point of contact, ensures they know your entire MSO, not just one practice. Our expertise is shared below-
Remote Billing Team with Specialty Pods: Dedicated specialists organized by specialty (cardiology, orthopedics, primary care, etc.)
AAPC-Certified Coders: CRCs and CPCs who understand your specialty mix and multi-practice coding nuances
Separate QA Team: Independent quality assurance reviewing work across all your locations with 3+ levels of supervision
This has resulted in consistency in processes and specialty-specific accuracy. It has unified supervision without managing multiple billing departments.
Example: Your cardiology practices in three states? They’re all served by our cardiology professionals, who understand catheterization coding, device implants, and cardiology-specific payer rules, regardless of the state the claim originates from.
3. Scalable Without the Hiring Nightmare
MSOs grow through acquisitions. You need an RCM partner who can scale instantly when you bring on new practices. With DrCatalyst, scalability or adding new practices is not a problem. We scale our team to match your growth. Our pricing scales with your collections, not your headcount. So, it remains transparent and aligned with your success. We have the capacity to support rapid MSO expansion without compromising quality.
4. Complete End-to-End RCM for Multi-Practice Operations
We don’t cherry-pick the easy tasks and leave you with the hard stuff. DrCatalyst handles the complete revenue cycle across all your practices. That includes-

5. Compliant By Design
MSOs face complex regulations, including CPOM laws, fee-splitting restrictions, Stark Law, and Anti-Kickback Statute. At DrCatalyst, compliance is woven in every fabric of our existence. Our approach includes-
Third-Party HIPAA Certification: Compliancy Group certification is a stamp on our authenticity
Multi-State Expertise: Our team stays up to date on state-specific billing regulations. For example, States like New York have prohibited percentage-based RCM costs
Payer Compliance: Our teams stay current on NCQA standards, CMS requirements, and payer-specific policies from time to time
Regular Audits: Quality assurance reviews across all locations ensure consistent compliance
Enterprise Security: CrowdStrike 24/7 monitoring, Google Workspace Enterprise, ActivTrak staff monitoring, and SumoLogic network tracking are helpful for MSO to stay compliant.
6. Unified Technology
Most MSOs inherit different technology stacks while working from one practice to another. During this acquisition, forcing standardization is expensive and disruptive, but leaving systems fragmented is also chaotic. DrCatalyst bridges the gap using a technological approach in the following ways:
Works Inside Your Existing Systems: No forced EHR switch
Advanced Clearinghouse Integration: Flawless claim submission across all platforms
Unified Dashboards: Aggregate data from all locations into one view
Real-Time Reporting: Performance visibility without logging into multiple systems
Automated Workflows: Eligibility verification, claim scrubbing, and payment posting automation
This leads to unified visibility and standardized processes without the cost and disruption of replacing working systems.
