The Importance of Accurate Gastroenterology CPT Codes

An optimized healthcare revenue cycle means all components are as efficient as possible and that you don’t have to go back and redo the same thing over and over again. A cornerstone of such an efficient process is using accurate medical billing codes.

There are thousands of medical billing codes to correspond to thousands of healthcare procedures, tests, and services – so there’s no wonder why it can be a complicated process. Medical practices that submit inaccurate codes then have to deal with rejected claims. Reworking claims means spending unnecessary time and effort on something that ideally was done correctly the first time around.

To put it in perspective, your gastroenterology practice should have a clean claims rate of 95%, meaning that 95% of your claims are processed successfully on the first submission. Most practices fall a little short of this and have an average clean claims rate of 75%-85%.

Let’s say each claim costs $25 to rework and you have an average 100 claims that need to be reworked each month – that adds up to a hefty $2,500 a month and $30,000 per year! One essential step you can take to avoid these costs is to ensure each claim uses the correct gastroenterology CPT codes.

  • Returning patient: An individual who has received services from a physician/NPP or anyone else of the same specialty and who belongs to your practice within the last 3 years.

  • 99203: 30-44 minutes
