In-House vs. Outsourced Laboratory Billing – Navigating the Best Path Forward for Your Lab
April 3, 2026
With today's complex medical laboratory environment growing more difficult by the day, effectively managing laboratory revenue cycle management (lab RCM) has become more essential and challenging than ever. With tighter reimbursement schedules, shifting payer rules, rising operational costs, and alarming staff shortages, the laboratory billing process, once considered a back-office task, has taken center stage.
To address this pressing issue, LigoLab called upon three lab billing experts to share their insights on one of the most critical decisions a lab faces today: whether to outsource or keep lab billing operations in-house.
Meet the Experts
Mick Raich is a 22-year veteran of the laboratory revenue cycle management industry and the founder of Vachette Pathology, known for his deep expertise in lab billing audits and strategy.
Denise Mazon is a healthcare RCM cycle leader with over three decades of experience, including 20-plus years covering the intricacies of laboratory billing.
Aram Avakyan is a former clinical pharmacist and now a specialist on LigoLab's lab revenue cycle management product team, uniquely positioned at the intersection of technology and patient care.

Why Laboratory Billing Matters Now More Than Ever
“Laboratory revenue cycle management is the foundation of the business,” said Raich. “I don’t care if you’re making toasters or lab results, you’ve got to get services billed. If you can’t bill in a correct, legal manner, you won’t be in business for long.”
Mazon echoed that sentiment, stressing that lab billing is not just a technical process, but a strategic function that demands constant attention.
“There’s so much to consider when determining how to tackle this critical function,” she said. “With payer rules changing more frequently than ever, often without notice, these organizations need lab revenue cycle management systems and teams that are nimble, informed, and responsive.”
Avakyan added that without effective laboratory billing software, labs can’t scale.
“A lot of labs are trying to grow or manage higher volumes,” he said. “But if you’re not collecting properly or efficiently, growth just creates more problems. Labs must maximize the first pass rate to achieve sustainable success.”

The State of the Laboratory Billing Process
Raich painted a sobering picture of the laboratory billing process landscape, comparing it to 2020 but with far fewer safety nets in place.
"Inflation has gone up, and costs have risen, but payers still lock labs into fixed contracts," he said. "You're dealing with hundreds of plans that can change terms twice a year, by newsletter. It's hard to keep up, and harder to make changes fast. The laboratory billing process needs to be faster and more responsive than ever."
Mazon highlighted the data dependency challenges labs face.
"Labs rely on requisitions from providers, and often those are incomplete," she said. "Missing demographics, insurance info, diagnosis codes, it all adds complexity, especially when you're already short-staffed."

Outsourced Lab Billing: Pros, Cons, and Considerations
So is outsourcing lab billing the answer?
"Outsourcing can reduce the pressure of hiring and managing staff and remove the need for in-house tech investment," said Mazon. "But you have to choose wisely. You're not their only client, and you risk deprioritization."
Raich, who has audited over 80 RCM management company vendors to date, noted that consolidation among laboratory billing vendors adds another layer of uncertainty.
"Staff turnover, shifting priorities, and slow response times can all erode trust and results," he warned. "When you outsource your laboratory billing, you're handing someone your wallet and saying, 'Please put money in here.' So you better know who you're trusting."
What to Evaluate Before Outsourcing Lab RCM
His advice for labs considering outsourcing:
- Visit the RCM cycle vendor's office in person
- Evaluate their technology stack and revenue cycle management tools
- Review contract terms carefully, especially liability limits

In-House Lab Billing: Control, Cost, and Commitment
In contrast, labs that have in-house lab billing gain transparency and control over their operations.
"With in-house lab billing, you can see what's happening in real time," said Avakyan. "You control workflows, you can tailor them, and you can react quickly when payers or policies change."
Raich advised labs to run a detailed ROI analysis, factoring in both direct and indirect costs. He also emphasized the value of autonomy.
"If you can run in-house lab billing for about two percent more than outsourcing, that two percent is the cost of autonomy," he said. "That's worth it if you can keep expertise in-house and ensure continuity."
The Investment Required for In-House Laboratory Billing
The downside of in-house laboratory billing is the upfront and ongoing commitment, the need for an effective laboratory billing system, staff training, and continuous maintenance. It should be noted here that the best Laboratory information system companies and LIS software vendors often support these technology needs by offering integrated laboratory software systems and ongoing updates. Labs must sustain these investments as payer rules and technology requirements evolve.

Common Laboratory Billing Challenges: What Labs Are Up Against
Labs face the same challenges across the industry, whether they handle laboratory billing internally or externally.
Claims That Never Go Out
"Three to five percent of claims may never even go out the door," said Raich, representing significant silent revenue loss that many labs don't realize is happening.
Delayed Denials Eroding Cash Flow
"The longer a claim sits in AR, the less likely it is to get paid," he added. Real-time denial management is essential to stopping this revenue drain before it compounds.
Incomplete Data From Providers
"You can't bill with half a requisition," Mazon warned. Missing demographics, insurance information, and diagnosis codes add complexity, especially in short-staffed environments where there is no bandwidth to chase down missing data manually.
Technology That Can't Keep Up
"Legacy laboratory information systems and lab revenue cycle management systems often can't keep up with today's complexity," noted Avakyan. Modern laboratory billing solutions with real-time visibility and automated workflows have become essential, not optional.

Automation, Analytics, and the Modern Lab
Laboratory billing automation remains a recurring theme for most lab CFOs.
“Automation removes barriers,” said Mazon. “It enables your team to focus energy on more complex challenges, like retention and compliance.”
Avakyan added that billing software for labs with automation must be paired with configurability.
“You need RCM tools that not only automate but also adapt,” he said. “The payer rules will change, so the question is whether your lab billing system can keep up.”
He also highlighted dashboards and real-time analytics as critical tools.
“You should be able to break down performance by CPT code, ICD-10, payer, and even draw location,” he said. “That data drives smarter decisions.”

Growing Labs: Planning for Scalability
When it comes to growth, all three experts were aligned; it is not just about doing more, but about doing better.
"Scalability isn't just volume," said Avakyan. "It's about being prepared, maintaining margins, and knowing where you want to be a year from now."
Raich advised labs to evaluate each new opportunity critically.
"Bigger isn't always better," he said. "You have to understand your margins by payer, by test. If you don't know your costs, you could be growing into a loss."

Frequently Asked Questions About In-House vs. Outsourced Lab Billing
What is the core difference between in-house and outsourced laboratory billing?
In-house lab billing means the lab manages its own revenue cycle management operations internally, with its own staff, technology, and workflows. Outsourced lab billing means handing those operations to a third-party vendor who bills on the lab's behalf. In-house offers greater control, transparency, and faster response to payer changes. Outsourcing reduces staffing and technology burdens but introduces risks related to prioritization, vendor reliability, and data security.
When does outsourcing lab billing make sense?
Outsourcing can make sense for labs that lack the internal expertise, staffing, or technology infrastructure to manage laboratory billing effectively in-house. It can reduce the pressure of hiring and training billing staff and remove the need for significant upfront technology investment. However, be sure to vet vendors thoroughly by visiting their offices, evaluating their technology stack, and carefully reviewing contract terms before committing.
What are the biggest risks of outsourcing laboratory billing?
The primary risks are deprioritization, being one of many clients, vendor staff turnover, slow response times when issues arise, and limited visibility into what is actually happening with your claims. Labs that outsource must monitor performance metrics closely and maintain contractual accountability.
How much more does in-house billing typically cost than outsourcing?
Labs that run in-house billing operations typically spend about 2% more than those that outsource, after accounting for all direct and indirect costs. This two percent represents the cost of autonomy, the ability to control workflows, retain institutional knowledge, and respond immediately to payer changes, and is worth paying for labs that have the resources to do so.
What percentage of lab claims never get submitted?
Three to five percent of claims may never go out the door, representing silent revenue loss that many labs fail to detect until it compounds into a significant financial problem. It is one of the most compelling arguments for real-time lab billing visibility and automated claim tracking, regardless of whether billing is in-house or outsourced.
What role does automation play in modern laboratory billing?
Automation removes manual bottlenecks from the laboratory billing process, handling eligibility verification, claim scrubbing, coding validation, and denial routing without requiring staff intervention at every step. Experts agree that automation is no longer optional because it frees lab billing teams to focus on complex challenges such as compliance and retention. At the same time, automation must also be configurable to adapt to changes in payer rules.
What analytics should labs track to manage billing performance?
Key metrics to monitor include first-pass claim acceptance rate, denial rate by payer and reason, days in accounts receivable, cost to collect, and reimbursement turnaround time. Real-time dashboards that surface these metrics daily, rather than monthly, allow laboratory billing teams to catch problems early and respond before revenue is lost.
What is the advantage of a unified LIS system and lab billing platform over separate systems?
When a lab information system and lab billing platform share a single database, billing can begin the moment an order is placed, with real-time eligibility checks, automated coding, and claim validation built into the workflow. Unified systems eliminate data silos, prevent manual re-entry errors, and remove synchronization delays that occur when labs interface with separate systems. Having results, documents, and laboratory billing all in one place is a game-changer for efficiency and accuracy.
