Maximizing Your Lab’s Profitability: The Case for In-House Lab Billing

Laboratory revenue cycle management (RCM) involves a complex combination of data, payer requirements, coding rules, policies, and regulations. With so many variables to manage, even successful pathology practices and clinical laboratories can struggle to prevent claim denials and rejections. 

Given the outsized impact laboratory billing has on margins and long-term profitability, one would expect it to be a top strategic priority for lab leadership.

Yet despite its importance, many laboratories still choose to outsource their laboratory billing operations. Why is that?

In this post, we cut through the marketing narratives of third-party laboratory billing services and take a clear-eyed look at why medical labs should look beyond the hype and seriously evaluate in-house lab billing.

Laboratory Billing Services: The Sales Pitch

Let’s kick off this discussion by examining the sales pitch laboratory billing services commonly use to attract customers.

Cost

Laboratory billing services often lead with this argument because even highly successful labs operate on thin margins and tightly controlled budgets. These service providers promote predictable pricing, typically a percentage of collections or a flat fee, while emphasizing the appeal of avoiding the cost and complexity of hiring, managing, and retaining a laboratory billing staff, as well as eliminating the need to license, support, and maintain in-house laboratory billing software.

Efficiency

Laboratory billing services position themselves as having an advantage by claiming deep specialization in lab revenue cycle management. They also emphasize flexibility, arguing that their services can scale with a laboratory's fluctuating needs, enabling leadership to focus on core diagnostic operations rather than on the complexities of lab RCM.

Expertise

Laboratory billing services often position themselves as uniquely qualified, citing deep industry experience and specialized knowledge as key differentiators. They emphasize their command of healthcare regulations and compliance requirements, and promote their best practices (along with access to advanced laboratory billing system software) as reasons they should be the obvious choice.

On the surface, the pitch is compelling. But a closer look reveals that outsourcing laboratory billing isn’t always as simple or advantageous as it may initially appear.

Laboratory Billing Services: The Reality

Now let’s focus on what’s missing from the sales pitch and unveil the real story.

The perceived cost savings of partnering with laboratory billing services can quickly diminish when factors such as transparency, control, autonomy, customization, and motivation are taken into consideration. 

Transparency

"When the cat's away, the mice will play."

People can use that old proverb to describe the approach that laboratory billing services use with their customers because it's a given that they will offer the lab a lot less transparency in day-to-day operations when compared to an in-house lab billing department using a modern system, one equipped with advanced laboratory billing solutions such as real-time monitoring and customized reporting capabilities.

Many laboratory billing services claim to offer "detailed reports" on RCM cycle performance and analytics. However, these reports often function like a black box, lacking transparency and failing to disclose the criteria used to evaluate performance or justify decisions made on the lab's behalf.

Outsourced arrangements lack clarity and give laboratory billing services the cover and unchecked freedom to go after only the low-hanging fruit that's easy to collect, while avoiding the more time-consuming and difficult cases.

The Tradeoffs and Risks of Outsourced Laboratory Billing

It's worth asking some hard questions. Will an outsourced laboratory billing service consistently go the extra mile, working every claim and pursuing every denial with the same rigor you would apply internally? 

Will your laboratory billing partner routinely audit processes and actively pursue continuous improvement while managing dozens of other clients? Or will complex cases receive less attention?

The rise in healthcare ransomware attacks adds another layer of concern. Introducing a third-party lab billing provider can expand an organization’s digital footprint and increase potential cybersecurity exposure. Outsourcing, particularly to offshore providers, can also introduce additional compliance considerations, including HIPAA requirements and the secure handling of protected health information (PHI).

What may appear to be short-term savings can ultimately create long-term financial, operational, and regulatory risk, costs that far outweigh any initial advantage.

Control and Autonomy

When it comes to ensuring your laboratory is paid accurately and promptly for the services it provides, are the potential savings from outsourcing worth giving up direct oversight and control of the laboratory billing process? 

We recently consulted a nationally known healthcare expert to get his take on control and the importance of keeping your lab billing in-house, and all should note his response.

"Overall, it may cost two percent more to perform your lab billing tasks in-house, but recovery of collectible dollars can be nominal, and you gain the autonomy of control over laboratory billing process outcomes," he said.

By keeping financial operations in-house and partnering with a modern laboratory billing software provider, laboratories can maintain greater visibility and control over revenue capture and optimize reimbursement. Over time, the billing team also develops deeper knowledge of internal processes, payer requirements, and financial workflows, supporting continuous improvements in RCM process efficiency, productivity, and overall performance. 

Customization

All labs are the same, except for their differences.

This is a common phrase used to describe the lack of customized laboratory billing solutions available.

Nearly every laboratory billing service claims to rely on "state-of-the-art" software. But that promise falls short if the laboratory billing system cannot be configured to support unique workflows, payer rules, and operational nuances.

Modern laboratory revenue cycle management software designed for in-house lab billing offers the level of flexibility and control teams need to manage today's complexity. These platforms adapt to real-world challenges and don’t force labs into rigid, one-size-fits-all processes.

For example, LigoLab's all-in-one laboratory information system (LIS) platform with advanced laboratory billing solutions includes a powerful Rule Engine that can define and automate virtually any RCM cycle scenario using configurable, prebuilt rules. When combined, these rules form end-to-end automated workflows that replace highly manual, error-prone lab billing tasks.

Preconfigured Lab Billing Rules Enable Smarter, Automated Decisions

Let's take this a step further and look at how preconfigured laboratory billing rules operate at a granular level.

Consider a scenario in which a claim is submitted to a payer and reimbursed at $98 instead of the expected $100. With an advanced laboratory revenue cycle management platform, the lab can define a rule that automatically accepts and closes the claim when the variance falls within an acceptable threshold.

Users can configure that same rule to escalate the claim for review when the underpayment exceeds the predefined amount, routing it directly to the appropriate decision-maker.

This level of configurability and automation ensures in-house lab billing teams focus their attention where it matters most, maximizing reimbursement while eliminating unnecessary manual work on low-impact variances.

Motivation

Now let's address the big elephant in the room. What motivates laboratory billing services? Is it fighting for every dollar on behalf of lab customers? Or is it maximizing profitability at the expense of its lab customers?

"Let's be candid, the incentives are misaligned," said LigoLab CEO Suren Avunjian. "Laboratory billing services are driven to maximize yield across their entire client base in the shortest amount of time."

Avunjian illustrated this dynamic with a common operating model.

"Imagine a laboratory billing service managing 100 clients with a fixed staffing model," he explained. "That team can efficiently process claims and collect payment on roughly 80 percent of them by focusing on the easiest, most straightforward cases."

So what happens to the remaining 20 percent?

"Recovering that final 20 percent, especially the last 5 to 10 percent, is far more difficult and resource-intensive," Avunjian continued. "It requires additional time, expertise, and effort."

From the laboratory billing service’s perspective, pursuing harder claims means higher labor costs and diminished margins. It’s more profitable to maintain the same staffing model, accept partial recovery, and simply onboard additional laboratory clients, rather than invest in efforts to extract maximum value from every existing customer.

"That's where the perceived savings disappear," Avunjian concluded. "When incentives aren't aligned, labs ultimately sacrifice revenue, even if outsourcing appears less expensive on paper."

Why Incentive Alignment and Deep Lab Knowledge Matter in Laboratory Billing

The nationally recognized healthcare expert we heard from earlier echoed Avunjian's concerns, emphasizing that outsourced laboratory billing providers require clear incentives, either rewards or consequences, to deliver optimal results. He also underscored that exceptional laboratory billing depends on deep, day-to-day familiarity with a lab's operations, payers, and workflows.

"Experienced, dedicated lab billing professionals who actively manage denials and payments will quickly identify errors and inconsistencies," he explained. "But when this work is handled by interchangeable staff focused solely on processing volume, critical insights are lost."

He added that most outsourced laboratory billing firms don’t dedicate a team exclusively to a single client. By contrast, in-house lab revenue cycle management allows organizations to build a dedicated team with deep institutional knowledge and direct accountability, providing greater control over financial performance and continuous improvement.

Frequently Asked Questions About In-House vs. Outsourced Laboratory Billing

What is the typical sales pitch outsourced laboratory billing services use?

Outsourced laboratory billing services typically emphasize predictable costs, often based on a percentage of collections or a flat fee, along with greater efficiency, specialized expertise, and extensive knowledge of lab billing best practices and compliance requirements. 

Why do outsourced laboratory billing services often lack transparency?

Many function like black boxes, offering little transparency into the criteria used to evaluate performance or justify laboratory billing decisions. This lack of visibility makes it difficult for laboratories to verify that every claim is being pursued thoroughly and effectively. 

Does keeping laboratory billing in-house really cost more?

According to a nationally recognized healthcare expert, in-house laboratory billing may cost about 2% more to operate, but higher collections and full control over outcomes often offset that cost.

Why are incentives often misaligned with outsourced laboratory billing services?

Outsourced providers are typically structured to maximize yield across their entire client base efficiently, meaning they often collect on the easiest 80 percent of claims but have less incentive to pursue the harder, more resource-intensive remaining claims.

How does customization affect laboratory billing performance?

Laboratory billing systems that can't be configured to specific workflows, payer rules, and operational nuances are less effective. Platforms with a configurable rule engine, like LigoLab's, allow customers to automate specific scenarios, such as accepting small claim variances automatically while escalating larger underpayments for review.

What are the security and compliance risks of outsourcing laboratory billing?

Bringing in a third-party lab RCM provider expands an organization's digital footprint and cybersecurity exposure, and outsourcing to offshore organizations in particular raises additional HIPAA compliance and PHI-handling concerns.
