What Is Laboratory Billing?
Laboratory billing is the process of coding and submitting claims for diagnostic tests performed by clinical labs, reference labs, and pathology practices. It requires precise CPT coding across 5,000+ codes, NCD/LCD compliance, ABN management, and payer-specific medical necessity documentation to avoid denials.
Laboratory billing is among the most technically complex areas of medical billing. Per analysis of CMS data, lab claims face denial rates 30–40% higher than standard physician claims — driven by bundling edit errors, NCD/LCD gaps, and incorrect presumptive vs. definitive drug testing code assignment. DrCare MSO's lab billing specialists are trained exclusively on laboratory CPT code sets and payer LCD libraries.

Lab Billing Is Uniquely Complex. Your Billing Team Has to Match That.
Laboratory billing operates under a separate CPT code set, a dedicated Clinical Laboratory Fee Schedule (CLFS), and National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) that vary by MAC jurisdiction. A single ordering diagnosis mismatch or missing ABN can trigger a CO-50 denial for every test on a patient's panel.
According to DrCare MSO's analysis of laboratory claims processed in 2024, panel bundling errors and NCD/LCD gaps accounted for 58% of initial denials at clinical labs that switched to DrCare MSO from previous billing vendors. Both categories are preventable with the right pre-submission workflow.
Every Test Performed Should Be a Test Paid For
We analyze your test menu against current CLFS fee schedules and payer contracts to identify underpayments and coding gaps. Our proactive approach to medical necessity verification and ABN management prevents denials before they happen — not after you've already lost the revenue.
Per MGMA's 2024 Practice Operations Survey, labs that conduct quarterly CPT code audits against payer remittances recover an average of 11–14% more revenue per test than those without a structured review cycle. DrCare MSO builds this audit into your monthly reporting package automatically.
According to DrCare MSO's analysis of laboratory claims processed across clinical and reference labs in 2024, practices that implemented our pre-submission NCD/LCD workflow reduced first-pass denial rates by an average of 45% within the first billing quarter.

Top Laboratory Claim Denial Reasons — and How We Prevent Them
These six ANSI denial codes account for over 70% of initial lab claim denials. Each is caught at the pre-submission stage in DrCare MSO's workflow.
| ANSI Code | Denial Reason | DrCare MSO Response |
|---|---|---|
| CO-50 | Lack of Medical Necessity | Pre-submission LCD checking and automated ABN requirement flags |
| CO-97 | Bundled Service | Automated panel vs. component CPT bundling scrubber before submission |
| CO-16 | Missing Information | Mandated claim field validation via direct LIS-to-billing interface |
| CO-151 | Payment Adjusted (PAMA) | Automated CLFS remittance audit with immediate underpayment appeal |
| CO-167 | Diagnosis Code Invalid | Real-time ICD-10 crosswalk validation against current FY code set |
| CO-22 | Coordination of Benefits | Real-time insurance eligibility verification prior to lab charge posting |

Key Benefits
Everything your laboratory needs for an optimized revenue cycle — in a single structure with no add-on fees.
The PAMA Impact on Laboratory Revenue
The Protecting Access to Medicare Act reset the Clinical Laboratory Fee Schedule using private payer market data. Most labs are still recovering revenue lost in the initial rate reductions — and future phase-in cuts remain on the table.
CLFS Rate Monitoring
DrCare MSO tracks every CMS Clinical Laboratory Fee Schedule update and models the impact on your specific test menu before each rate cycle takes effect — giving you time to adjust payer contracts and test mix.
LCD/NCD Compliance Engine
Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) dictate which diagnoses support medical necessity for each CPT code. Our pre-submission engine checks every claim against the applicable MAC's current LCD — before it leaves the system.
Test Utilization Analytics
Monthly reporting on ordering patterns, reimbursement trends, and denial rates by CPT code gives your laboratory the data needed for strategic decisions about test menu expansion, payer contract negotiations, and compliance risk management.
"Their understanding of laboratory billing nuances is unmatched. Our net collections increased by 33% within the first quarter, and denials dropped by nearly half — primarily because they caught our LCD gaps before the claims went out."
Dr. Robert Chen
Laboratory Director · Advanced Diagnostics Lab
"We were hemorrhaging revenue on toxicology claims because our previous biller was coding presumptive and definitive tests identically. DrCare MSO fixed it in the first week. Collections on tox testing went up 28% in 60 days."
