A Message from Jim O’Neill:

National Sales Director,

Laboratory Division

 

Whether we’ve connected at AMP, crossed paths on LinkedIn, or this is your first time reading the Lab Digest — welcome. Our goal with each issue is simple: bring forward the operational insights labs can actually use, not just another layer of industry noise.

Right now, the labs I speak with are facing growing friction from prior authorization shifts, documentation demands, and denials that quietly cut into margins. If you’re exploring ways to better navigate these challenges in 2026, this edition offers a practical lens on what to track, what to improve, and where we’ve seen labs turn small adjustments into major wins.

Glad you’re here. Let’s keep the conversation going.

2025 Tightened the Screws. 2026 Will Test the Controls.

 

As we enter the new year, most laboratories aren’t recovering from a single disruption — they’re navigating the cumulative weight of reimbursement pressure, payer scrutiny, staffing gaps, and compliance complexity that intensified throughout 2025.

The reality heading into 2026 is clear:
Labs are no longer judged solely on what they bill — but on how defensible, traceable, and audit-ready the entire billing pathway is, from ordering through post-payment monitoring.

This January issue takes a practical, year-in-review lens and focuses on what 2026 means for billing performance, compliance posture, and revenue stability — especially for molecular, pathology, and toxicology labs.

At ADS, we help labs navigate reimbursement complexity with scalable revenue cycle strategies that improve visibility, reduce leakage, and strengthen documentation at every step.

2025 in Review: The Lab Revenue Cycle Became “Proof-Driven”

 

Across 2025, several pressure points converged into a single operational expectation: show your work. Documentation was no longer just a supporting act in the billing cycle — it became the main event. Medical necessity became the cornerstone of both reimbursement and compliance strategy, and its absence led to growing volumes of rework, delays, and write-offs.

At the same time, payer behavior shifted noticeably. More requests for documentation, increased scrutiny of ordering patterns, and stricter review of medical necessity created new layers of friction for lab billing teams. And the reimbursement instability tied to CLFS and PAMA meant that even successfully processed claims didn’t always yield consistent payment.

The takeaway was straightforward:
Labs that treated compliance as a back-end billing function spent 2025 reacting. Labs that embedded controls upstream spent 2025 stabilizing. And in 2026, that operational divide will become even more visible as payers continue to push review logic earlier in the claim lifecycle.

That distinction will matter even more in 2026.

By the Numbers: Revenue Leakage Is No Longer “Manageable”

 

Industry data from both provider and laboratory organizations confirms what many lab leaders experienced firsthand in 2025 — revenue leakage is accelerating, not flattening.

According to the Medical Group Management Association (MGMA):

  • Healthcare organizations reported 3–5% of total net revenue lost annually due to preventable revenue cycle issues
  • The top contributors were denials, underpayments, delayed billing, and documentation gaps

In the lab space specifically:

  • Molecular and toxicology testing saw double-digit denial growth due to tighter payer edits and documentation demands
  • Many labs still lack a systematic comparison between expected and actual reimbursement, leaving underpayments undetected

The implication for 2026 is clear:
When reimbursement is under pressure, even small, unaddressed leaks compound quickly.

Reimbursement Volatility Isn’t a One-Time Event

 

The laboratory reimbursement environment remains unsettled. While industry groups continue to advocate for more predictability in pricing and policy — particularly around CLFS and PAMA — there is little clarity on how or when lasting change will occur. For lab leaders, this isn’t just a policy concern — it’s an everyday operational challenge.

When reimbursement is unpredictable, revenue cycle teams are under pressure to account for every possible risk. A few cents lost per test can add up to thousands in missed revenue over time. This means labs can no longer afford to treat revenue leakage as a back-office issue. Leakage now lives in workflows, in payer relationships, and in the lag between service and submission.

Understanding your exposure early in the year is essential. Waiting until March or mid-year means playing catch-up when you’re already underwater.

Compliance & Enforcement Trends Are Closer Than They Appear

 

Recent enforcement activity continues to spotlight familiar vulnerabilities — particularly in areas where documentation and medical necessity do not withstand review. But what’s shifting is how closely payer behavior now mirrors regulatory enforcement priorities.

We’re seeing more than just isolated audits. Payers are leveraging increasingly sophisticated algorithms to detect documentation inconsistencies, identify outlier ordering patterns, and initiate proactive pre-payment reviews. These methods often resemble federal enforcement logic, meaning even labs operating within guidelines may experience greater friction.

This shift underscores a broader industry reality: documentation and compliance aren’t just legal safeguards — they’re operational levers.

Labs can’t afford to rely solely on reactive audit defense. Instead, 2026 calls for systems that build defensibility into the workflow itself, reducing risk before it reaches the payer.

 

The shift: Move from audit response readiness to audit prevention by design 

Payer Behavior Is Moving Upstream

 

Across both commercial and government payers, the trend is unmistakable: more front-end controls, stricter claim review criteria, and accelerated use of automation in prior authorization and denial logic.

For laboratories, this means access workflows — not just billing processes — are now under the microscope. We’re seeing more cases where:

  • Prior auth denials result from minor documentation gaps
  • Ordering pathways are questioned based on historical patterns
  • Payers apply policy edits before claims are even accepted into their adjudication system

The implications are huge. Revenue integrity in 2026 is less about fixing claims after submission — and more about preventing unpayable claims from being created at all.

Molecular, Pathology & Toxicology Labs: Where Risk Concentrates

 

High-complexity testing will remain a focal point in 2026. These modalities are consistently subject to more aggressive pre- and post-payment scrutiny because they involve higher reimbursement and more nuanced medical-necessity standards.

From prior authorization requirements to payer-specific edits and documentation triggers, the margin for error is narrow. Molecular billing in particular continues to be one of the largest sources of preventable revenue leakage — and one of the most challenging to manage without specialized workflows.

Labs performing complex testing must:

  • Integrate payer-specific documentation rules into ordering and intake
  • Align coding logic with both CPT accuracy and medical necessity criteria
  • Monitor real-time denial and underpayment drivers to make mid-cycle corrections

What “Ready” Looks Like in 2026

 

The labs that protect revenue and reduce compliance exposure this year tend to share a few traits — and they all start upstream. It’s not about working harder on the back end. It’s about building smarter, more predictable systems from the start.

Readiness in 2026 looks like:

  • Scalable documentation discipline: Embedded protocols for capturing required elements at the point of order
  • Denials intelligence that drives upstream change: Not just reporting, but trends that feed workflow updates
  • Underpayment awareness: Automated processes that surface shortfalls without relying on manual audits
  • Pattern-based compliance monitoring: Early alerts that catch utilization or ordering anomalies before they trigger payer action
