The Billing Codes for Gastroenterology
The main changes that surround the new codes, revised codes, and remove the old codes is the heightened specificity. For this reason, you will need an expert coder to keep up with the changes. In this way, you wouldn’t have to worry about claim rejections and claim denials. Most often than not, these codes will start to apply these:
- K35.20; which refer to acute appendicitis with generalized peritonitis, without an abscess;
- K35.21; which refers to acute appendicitis with generalized peritonitis, with an abscess;
- K35.30; which refers to acute appendicitis with localized peritonitis;
- K35.31, which refers to appendicitis with localized peritonitis and gangrene, without any perforation
