Procedural coding is essential to accurate medical billing and payment, but even experts can make errors. A misplaced modifier, wrong code order, or outdated codes are just the beginning. These mistakes can cause claim denials, compliance problems, and payment delays.

The good news is that most of these are preventable with the correct information and close attention to detail. In this blog, we’ll analyze some of the most frequent mistakes in procedure coding, why they occur, and how to fix or avoid them!

What is Procedural Coding?

Procedural codes indicate what a physician or nurse performs on a patient, such as administering a shot, performing surgery, or taking blood pressure.

These codes are not for record-keeping purposes only. Payers utilize them so they can properly pay the medical care provider. If the code is incorrect, the payor may pay insufficiently, deny the claim, or request additional information. That causes delays, confusion, and extra effort for everyone.

That is why coding correctly is so critical. A single miscode can create huge issues with billing, patient care documentation, and even legal compliance. Getting the coding right ensures the healthcare practitioner is correctly compensated and the patient’s record is accurate.

Mistake #1: Incorrect Use of Code

One of the most frequent coding errors is coding for an incorrect procedure. This error may involve as little as coding for a right leg instead of a left one or as much as coding for a surgery that didn’t occur.

Double-check all codes with the chart and notes on every patient. Slow down, no matter how busy you are. It is better to be correct than speedy.

Most denied claims are due to coding errors and are avoidable with proper attention to detail.

Mistake #2: Omitting Modifiers

Modifiers are small codes that provide additional information about a process, such as when it was performed twice or unusually. Omitting them may confuse the insurer and delay payment.

Learn how to use every modifier and when to apply it. It’s like putting only the correct punctuation on a sentence to make everything intelligible.

Mistake #3: Failing to Keep on Trend

Medical codes are not static. Medical codes shift every year. Using outdated codes may result in denied claims even when everything else is valid.

Keep current with new coding books and programs. Our students at Northwest Career College learn the latest codes and how to continue learning once they are out of school.

Mistake #4: Skipping the Details

Medical billing and coding staff sometimes innocently omit key information, such as the length of a process or the devices utilized. These little details count when it comes to billing.

Look at the whole picture. Read everything written, and don’t assume. Don’t guess unless you don’t understand. It is better to double-check than to think.
