How Modern LIS Systems Are Transforming Clinical Workflow, Laboratory Billing, and Scalability

In Part 1 of this series, we explored the current state of automation in laboratory medicine and why modern laboratories can no longer rely on disconnected systems, paper-based workflows, and manual processes to remain competitive.

Read Part 1 of the Series: Why Modern Labs Must Move Beyond Manual Workflows and Legacy LIS Systems

The reality is clear: automation has become a core operational strategy for pathology groups, molecular diagnostics organizations, and independent clinical laboratories trying to overcome staffing shortages, rising reimbursement pressure, increasing compliance requirements, and growing test complexity.

But while nearly every laboratory today claims to be “automated,” the degree of actual automation varies dramatically from one organization to another.

Some still rely heavily on manual accessioning, spreadsheet-based laboratory workflow, and disconnected information systems and data management for operations and finances. Others are leveraging advanced laboratory information system (LIS) software with rules-based automation to orchestrate workflows from specimen receipt through reimbursement.

The difference between these two environments is enormous.

This installment examines where automation is currently delivering the most meaningful operational gains in modern laboratories, which areas remain stubbornly manual, and why integrated LIS systems are increasingly becoming the operational backbone of efficient, scalable laboratory medicine.

The Most Meaningful Gains Are Happening Outside the Analyzer

For years, automated labs centered primarily on instrumentation.

Clinical analyzers, auto-verification, and lab track system software transformed the analytical phase of laboratory testing. But today, the greatest opportunities for operational improvement are increasingly occurring outside the analyzer itself.

Modern laboratories are now focusing heavily on automation in:

• Pre-analytical workflows
• Post-analytical workflows
• Lab revenue cycle management
• Workflow orchestration
• Data visibility
• Client communications
• Report distribution
• Exception management

This shift is redefining how laboratories evaluate the best laboratory information system software and LIS software vendors.

Industry Insights: Why the Future of the Laboratory Information System Must Be Active, Intelligent, and Integrated

Pre-Analytical Automation Is Eliminating Massive Amounts of Manual Labor

The pre-analytical phase remains one of the most labor-intensive areas of the clinical lab workflow.

This is where many laboratories continue to encounter operational challenges, including:

• Paper-based requisitions
• Handwritten orders
• Manual demographic data entry
• Specimen routing inefficiencies
• Insurance verification delays
• Labeling inaccuracies
• Missing or incomplete documentation

These inefficiencies create downstream operational problems that impact turnaround times, reimbursement, and patient care.

Modern LIS systems are increasingly addressing these challenges through rules-based workflow automation.

OCR-Based Requisition Scanning

One of the most significant advancements in recent years has been the adoption of OCR-enabled requisition processing. Rather than relying on manual data entry from paper or faxed orders, laboratories can now batch-scan requisitions and automatically transform them into structured electronic orders. 

This reduces:

• Data entry labor
• Human transcription errors
• Order delays
• Specimen handling inefficiencies

More advanced laboratory information system software platforms also verify demographics against payer databases in real time during order entry. This improves clean claim rates while reducing downstream billing corrections.

Barcode-Driven Sample Tracking Improves Laboratory Workflow Management

Another major advancement is barcode-driven specimen tracking.

Modern LIS laboratory information system platforms increasingly support real-time specimen visibility throughout the lab workflow.

Every scan creates traceability.

This improves:

• Chain-of-custody management
• Specimen routing
• Department coordination
• Turnaround time monitoring
• Compliance documentation

When tied to configurable workflow rules, the advanced LIS system can automatically determine where a specimen should go based on:

• Test code
• Specimen type
• Client preferences
• Instrument availability
• Department workload

This eliminates countless manual handoffs that still exist in many laboratories today.

Rules-Based Automation Is Transforming Result Review

One of the most operationally transformative advancements in laboratory automation today is auto-verification. 

Historically, laboratorians manually reviewed nearly every result before releasing it. While this approach remains important for abnormal or complex cases, applying the same level of review to routine normal results can create substantial operational inefficiencies. 

Modern LIS systems increasingly address this challenge by using configurable rules that automatically verify and release routine results. 

These rules may evaluate:

• Reference ranges
• Delta checks
• Instrument flags
• QC status
• Patient history
• Reflex testing criteria

Results that meet defined criteria can be automatically released without human intervention.

This creates an exception-based workflow model.

Instead of spending time reviewing normal results, laboratorians focus their attention on the cases that genuinely require expertise and investigation.

Labs implementing robust auto-verification workflows are seeing major improvements in:

• Turnaround times
• Staffing efficiency
• Operational scalability
• Error reduction

Some organizations are now automatically verifying between 70 and 80% of routine testing volume, significantly reducing manual review requirements.

Post-Analytical Automation Is Improving Client Service

Post-analytical workflows have historically remained surprisingly manual in many environments.

Even labs with sophisticated analyzers often continue managing labor-intensive manual processes, such as:

• Report distribution
• Client communication
• Fax delivery
• Customized formatting
• Add-on requests
• Critical value notifications

The best laboratory information system software platforms automate these functions through configurable delivery logic.

Results can now be:

• Distributed electronically
• Routed based on client preference
• Formatted dynamically
• Scheduled automatically
• Delivered via portal integration
• Triggered based on rules

This reduces administrative workload while improving service consistency.

Laboratory Billing Automation Is Becoming a Competitive Necessity

One of the most important shifts occurring in laboratory medicine is the growing recognition that laboratory billing automation is just as important as operational automation.

Historically, laboratories treated lab billing as a disconnected back-office process.

That laboratory revenue cycle management model is rapidly becoming obsolete.

Today’s reimbursement environment is too complex for manual workflows to scale efficiently.

Laboratories face:

• Constant payer rule changes
• Growing denial rates
• Complex coding requirements
• Increased audit scrutiny
• Prior authorization complexity
• Eligibility verification demands

Laboratories that continue relying on disconnected laboratory billing systems and manual reconciliation processes face increasing exposure to revenue leakage and operational inefficiencies. 

Industry Insights: What Are the Best Software Solutions for Laboratory Billing?

Integrated Medical LIS and Lab Billing Platforms Are Reshaping Revenue Cycle Management

This is why integrated LIS systems with embedded laboratory billing functionality are becoming increasingly important.

Platforms like the all-in-one LigoLab Informatics Platform unify laboratory operations and lab revenue cycle management within a single architecture.

This enables automation to begin at the point of order entry rather than after testing is complete.

Automation can now support:

• Real-time eligibility verification
• Insurance discovery
• Automated CPT/ICD coding
• Claim scrubbing
• Billing validation
• Denial prevention
• Claim generation
• Payment reconciliation

The result is greater financial transparency and significantly improved operational efficiency.

Most importantly, the laboratory no longer operates with separate operational and financial data silos and their associated bottlenecks.

Legacy LIS Systems Continue to Limit Automation Potential

Unfortunately, many laboratories still operate on LIS software platforms that were never designed for modern workflow automation.

These environments often require:

• Manual exports/imports
• Spreadsheet reconciliation
• Swivel-chair workflows
• Custom middleware patches
• Human data synchronization

Every disconnected workflow creates operational drag.

Many laboratories underestimate the amount of staff time and effort devoted to simply transferring and reconciling information across multiple systems. 

This is one reason modern labs increasingly prioritize the following when evaluating LIS vendors.

• Unified architecture
• Open interoperability
• Embedded workflow engines
• Integrated billing
• Configurable automation
• Real-time dashboards

Automation Still Has Limits

Despite major progress, there are still areas of laboratory medicine where automation remains limited.

Microbiology

Microbiology remains one of the most difficult disciplines to automate fully.

While automation has improved plate inoculation, incubation, imaging, and instrument interfacing, the interpretive work of identifying clinically significant organisms still requires substantial human expertise.

Compliance and Quality Management

CAP, CLIA, and regulatory documentation workflows also remain heavily manual in most laboratories. Tasks such as competency assessment, proficiency testing, procedure management, and audit preparation still depend heavily on human oversight.

Relationship Management

Client onboarding, physician communication, troubleshooting, and operational consulting also remain fundamentally human activities.

Automation can support these interactions, but not replace them.
