CPT 49320 | Diagnostic Laparoscopy For Abdominal Examination With Specimen Collection

CPT code 49320 is a diagnostic laparoscopy procedure used to examine the abdomen, peritoneum, and omentum for evidence of disease or trauma, with the option to collect specimens for lab analysis.

What Is CPT Code 49320?

CPT 49320 is a diagnostic laparoscopy procedure in which the abdomen, peritoneum, and omentum are examined for evidence of disease or trauma using a small incision, camera, and instruments.

The provider may collect specimens for laboratory analysis through suction or washing of the area. The procedure includes the closing of any incisions made.


The CPT book describes CPT code 49320 as: “Laparoscopy, abdomen, peritoneum, and omentum, diagnostic, with or without collection of specimen(s) by brushing or washing (separate procedure).”


When the patient is appropriately prepped and anesthetized, the provider makes a small incision at the umbilicus and uses this opening to inflate the abdomen and lift the abdominal wall away from the organs to improve visualization of the site to be treated.

He then makes an additional small incision and inserts a camera and instruments to perform the procedure. Finally, he uses suction to evacuate any free fluid.

He examines the organs and the structures for evidence of disease or trauma. Then, the provider performs brushing and washing any suspicious areas for laboratory analysis.

The provider then irrigates the area, checks for bleeding, remove instruments, and closes the incisions. 

How To Use CPT 49320

CPT code 49320 describes the exploration of the abdomen without treatment via a laparoscopic approach.

It also describes the work associated with opening and closing the abdomen for many treatments of diseases of organs or structures of the abdomen by laparoscopy.

For this reason, CPT 49320 is only assigned when no therapeutic treatment is performed during the same operative session.

This may happen when exploration finds no evidence of disease or when the condition is so extensive that no surgical treatment is possible. 49320 may not be assigned in addition to any therapeutic, surgical treatment in the abdomen, even if exploration is extensive.
