CPT Code 49320: Diagnostic Laparoscopy of Abdomen, Peritoneum, and Omentum (Separate Procedure)

CPT 49320 is used to report diagnostic laparoscopy procedures involving the abdomen, peritoneum, or omentum, with or without specimen collection by brushing or washing. It is often performed to evaluate unexplained abdominal symptoms or the staging of disease.

Not usually. CPT 49320 is considered a “separate procedure”, meaning it’s generally bundled into a more extensive therapeutic service unless the diagnostic component was distinct and unrelated. In such cases, you may use Modifier 59, accompanied by supporting documentation.

No. The brushing or washing of specimens for cytologic or microbiologic examination is already included in CPT 49320 and should not be billed separately.
