Coding Backlogs and DNFB: Warning Signs to Watch

This blog is part of our series: Operational Triggers That Signal It’s Time for Coding Support

Growing coding backlogs and rising DNFB often signal more than a temporary delay. In many healthcare organizations, these trends point to deeper issues with coding capacity, staffing, workflow efficiency, or sustained volume pressure.

In this blog, we break down why coding backlogs develop, what DNFB trends may be telling you, and how organizations can stabilize operations without sacrificing coding accuracy.

Backlogs Rarely Happen Overnight

A backlog is typically the result of gradual imbalance—not a single event.

It builds when:

• Coding volume consistently exceeds available capacity
• Productivity expectations are difficult to sustain
• Staffing gaps go unfilled longer than anticipated
• Workflow inefficiencies slow throughput

Because the change is incremental, it often goes unnoticed until the backlog becomes difficult to manage.

By the time it’s visible, the underlying issue has usually been in place for some time.

DNFB Isn’t Just a Metric—It’s a Signal

DNFB (Discharged Not Final Billed) is often tracked as a financial or operational KPI.

But it’s more than that—it’s an early indicator of coding strain.

When DNFB begins to trend upward, it may reflect:

• Delays in coding completion
• Bottlenecks in review or query processes
• Competing priorities across teams
• Capacity limitations within coding staff

Treating DNFB as just a number to bring down can miss the bigger picture. The goal isn’t simply reduction—it’s understanding what’s driving the increase in the first place.

Why “Catch-Up Mode” Creates More Risk

When backlogs grow, the instinct is to accelerate.

Teams shift into catch-up mode—working faster, extending hours, and pushing volume through the system.

While this may reduce backlog temporarily, it can introduce new challenges:

• Reduced time per chart, increasing the likelihood of missed details
• Inconsistent application of guidelines, especially across multiple coders
• Limited opportunity for QA review, as speed becomes the priority
• Higher potential for rework, which adds to overall workload

In other words, the effort to fix the backlog can unintentionally create additional downstream work.

Why Backlogs Tend to Repeat

One of the most common frustrations organizations face is that backlogs return—even after they’ve been resolved once.

That’s because many backlog reduction efforts focus on the symptom (volume) rather than the cause (capacity or process).

Without addressing the underlying issue:

• Staffing levels may still be insufficient
• Productivity expectations may remain unrealistic
• Workflow inefficiencies may persist
• Volume fluctuations may not be accounted for

As a result, the cycle repeats.

Early Signs a Backlog Is Becoming a Larger Issue

Like short-term gaps, backlog-related challenges often build gradually.

Some key indicators include:

• Consistent upward trend in DNFB over time
• Extended coding turnaround times beyond normal benchmarks
• Ongoing reliance on overtime to maintain pace
• Delayed financial reporting tied to coding completion
• Increased pressure across coding, CDI, and revenue cycle teams

These signs suggest that the issue is no longer temporary—and may require a different approach.

Stabilizing Without Sacrificing Accuracy

Addressing a backlog effectively requires more than speed. It requires balance.

Stabilization efforts should focus on:

• Adding capacity without overloading existing teams
• Maintaining consistent coding practices during high-volume periods
• Ensuring quality review processes remain intact
• Prioritizing both throughput and accuracy—not one at the expense of the other

The objective isn’t just to eliminate the backlog—it’s to prevent it from recurring.

A More Sustainable Approach to Backlog Management

Organizations that successfully manage backlogs tend to take a more proactive approach.

That includes:

• Monitoring trends early—not just reacting to spikes
• Aligning staffing and capacity with realistic volume expectations
• Addressing workflow inefficiencies alongside volume challenges
• Planning for fluctuations rather than assuming steady-state operations

Because once a backlog reaches a certain point, recovery becomes more complex—and more resource-intensive.
