A single incorrect code can mean a delayed claim, a denied reimbursement, or worse, a compliance issue. While most practices are laser-focused on delivering excellent care, many underestimate how much money they’re leaving on the table because of something as “small” as a coding error. But these aren’t just small mistakes. They add up—and fast. In this blog, we’ll break down why coding errors are costing practices thousands, how to spot the most common issues, and what you can do to protect your revenue, your reputation, and your team.
Why Medical Coding Matters
Every time a patient receives care, a record is created, and that record must be accurately translated into a set of standardized codes. These codes are then used to bill insurance providers, track outcomes, and maintain compliance.
That sounds simple—but it’s not.
Between constantly changing guidelines, payer-specific requirements, and the pressure to code quickly, mistakes happen. And when they do, your revenue cycle takes the hit.
The Hidden Costs of Inaccurate Coding
The average cost of reworking a denied claim is $25 per claim, according to the Medical Group Management Association (MGMA). If you’re reworking dozens—or hundreds—of claims each month, you could be losing tens of thousands of dollars annually in rework alone.
But the costs don’t stop there:
- Delayed payments mean cash flow problems
- Denied claims can require time-consuming appeals
- Inaccurate coding can trigger audits or fines
- Staff burnout increases when they’re constantly fixing mistakes
And for many practices, these errors go unnoticed until the financial damage is already done.
The Most Common Coding Errors (And How to Avoid Them)
Some coding errors are simple. Others are the result of unclear documentation or outdated training. Here are a few that show up again and again:
1. Upcoding or Downcoding
Using a higher or lower level of service code than what was actually provided. Both are red flags for auditors and can lead to serious penalties.
How to avoid it: Ensure coders fully understand evaluation and management (E/M) coding guidelines and have clear documentation from providers.
2. Missing or Incomplete Documentation
Coders can’t code accurately if they’re missing key details like diagnosis, treatment rationale, or procedure notes.
How to avoid it: Encourage providers to document in real-time and include all required elements for each encounter.
3. Using Outdated Codes
CPT, ICD-10, and HCPCS codes are updated regularly. Using expired codes can lead to automatic denials.
How to avoid it: Use software that updates regularly and offer refresher training to your team when changes are rolled out.
4. Incorrect Modifier Use
Modifiers are used to provide additional context, like whether a procedure was bilateral or if it was a repeat service. Misusing them is a common cause of denials.
How to avoid it: Create easy-to-follow modifier cheat sheets or quick guides for your coding team.
Why Even Small Coding Errors Have Big Consequences
Let’s say your practice submits 100 claims a day. If just 5% have coding errors, that’s 5 problematic claims daily, or 25 a week. Multiply that over a month or year, and suddenly you’re dealing with thousands in delayed or denied revenue. Plus, repeated errors can impact your payer scorecards, which affects reimbursement rates and audit frequency. The ripple effects go beyond dollars—they impact your team’s efficiency, morale, and your patient experience too.
How Training Your Team Can Help
The good news? Most coding issues can be prevented—with the right training.
A well-trained coding team isn’t just faster; they’re more accurate, confident, and consistent. Investing in coding education improves compliance, reduces denials, and makes your entire revenue cycle smoother.
Here’s what effective training looks like:
- Ongoing refresher courses for ICD-10, CPT, and HCPCS
- Updates on payer-specific rules and audit triggers
- Workshops on E/M coding and documentation improvement
- Case studies and hands-on examples to apply learning in real-world settings
Consider Remote Coding Support to Reduce Errors and Save Money
Not every practice has the time, budget, or bandwidth to train an in-house coding team to perfection. Remote coding support can turn things around when accuracy and efficiency matter most.
Working with a trusted remote coding partner, like MedCore Solutions, can help you:
- Cut down on billing backlogs
- Eliminate costly coding errors
- Get claims out faster—and get paid faster
- Improve staff productivity by offloading complex tasks
Our certified coders work seamlessly with your team, align with your workflows, and help you reduce revenue leakage—all while maintaining compliance.
Final Thoughts: Don’t Let Coding Errors Drain Your Practice
You don’t need to accept coding errors as a part of doing business. Whether you build your team’s knowledge through training or tap into expert support, improving your coding process is one of the most cost-effective ways to strengthen your practice.
Clean claims = faster payments. Fewer denials = stronger cash flow.
And a reliable coding strategy means your team can focus less on paperwork—and more on patient care.
