CPT 43775 | Sleeve Gastrectomy: A Laparoscopic Weight Loss Surgery

CPT code 43775 refers to a laparoscopic sleeve gastrectomy. This weight loss surgery involves reducing the size of the stomach by removing a portion of it and reshaping the remaining part into a tube.

What Is CPT Code 43775?

CPT 43775 describes a laparoscopic surgical procedure called a longitudinal gastrectomy, also known as a sleeve gastrectomy.

This weight loss surgery involves reducing the size of the stomach by removing a large portion of it and reshaping the remaining part into a tube or sleeve.

The procedure is typically performed laparoscopically, which means it is done through several small incisions in the abdomen rather than one large incision.

The provider inserts a laparoscope, a thin tube with a camera on its end, through one of the incisions to view the inside of the abdomen and guide the surgery.

The procedure is done under general anesthesia, and the provider may use staples, stitches, or special glue to close the incisions afterward.

The goal of the procedure is to help the patient lose weight by limiting the amount of food that can be eaten at one time and reducing the production of hunger hormones.

Description

The CPT book describes CPT code 43775 as: “Laparoscopy, surgical, gastric restrictive procedure; longitudinal gastrectomy (i.e., sleeve gastrectomy).”

Procedure

When the patient is appropriately prepped and anesthetized, the provider makes a small incision in the belly button or lower abdomen and fills the abdominal cavity with carbon dioxide to lift the abdominal wall away from the internal organs.

Then, he inserts a laparoscope through the belly button. A video camera in the scope allows the provider to see inside the abdominal area using monitors in the operating room.

It also allows the provider to take pictures of any problem areas he discovers. Next, he makes a lengthwise incision from the top outer portion of the stomach to the distal antrum and removes about 60 percent of the bulk of the stomach.

He then sutures the stomach remnant in line with the opening from the esophagus to the opening into the duodenum so that the stomach resembles a tube or sleeve.

This preserves the pyloric sphincter, results in a more natural transit of food from the stomach to the duodenum, and avoids dumping syndrome, the overly rapid transport of food through the stomach into intestines, that is seen with distal gastrectomy.

The provider then deflates the abdomen, removes the trocars, and closes the incisions with staples, stitches, or glue.

How To Use CPT 43775

CPT 43775 is an inpatient-only procedure code.

Medicare or other payers may not cover operative procedures for morbid obesity; check with the payer to determine coverage.

Report CPT code 43775 for laparoscopic longitudinal gastrectomy or sleeve gastrectomy.

For laparoscopic Roux–en–Y with a roux limb of 150 cm or less for morbid obesity, report CPT 43644, and for laparoscopic gastric bypass and small intestine reconstruction to limit absorption or for a roux limb greater than 150 cm, report CPT 43645.

For the same procedure but using an open technique, report CPT 43846, and for open gastric bypass with small intestine reconstruction to limit absorption or for a roux limb greater than 150 cm, report CPT 43847.

For a vertical–banded gastroplasty for morbid obesity, report CPT 43842, and for a gastric restrictive procedure other than vertical–banded gastroplasty without gastric bypass, report CPT 43843.
