Summary & Overview

CPT 43775: Laparoscopic Sleeve Gastrectomy for Morbid Obesity

CPT code 43775 represents laparoscopic sleeve gastrectomy, a minimally invasive bariatric surgery used to treat morbid obesity. This procedure involves reducing the stomach's size by removing a significant portion, resulting in a sleeve-shaped stomach. It is performed either as a standalone surgery or as the initial stage in a two-part approach for high-risk patients. The code is nationally significant due to the rising prevalence of obesity and the demand for effective surgical interventions.

Major payers covering this procedure include Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare. The publication provides a comprehensive overview of payer coverage, typical sites of service, and clinical context for 43775. Readers will gain insights into current benchmarks, policy updates, and the role of laparoscopic sleeve gastrectomy in bariatric care. The analysis also highlights relevant modifiers, associated taxonomies, and ICD-10 diagnoses commonly linked to this procedure, offering a clear understanding of its billing and clinical landscape.

CPT Code Overview

CPT code 43775 describes a laparoscopic sleeve gastrectomy, a surgical procedure in which the provider reduces the size of the stomach by removing a large portion in a vertical fashion. This results in a long, cylindrical stomach and does not require rerouting the digestive tract or creating a bypass. The procedure is performed either as a single intervention or as the first stage of a two-part treatment for morbid obesity in high-risk patients.

This service is classified as Surgical – Bariatric (Lap Sleeve Gastrectomy) and is typically performed in a hospital outpatient setting (POS 19) or an ambulatory surgery center (POS 24).

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult patient with morbid obesity, often defined by a body mass index (BMI) of 35 or greater, who has not achieved significant weight loss through conservative measures such as diet, exercise, and medical management. The patient may also have obesity-related comorbidities, including hypertension, chronic kidney disease, or pulmonary hypertension. The clinical workflow includes preoperative evaluation by a bariatric surgery team, assessment of comorbid conditions, and multidisciplinary clearance. The procedure, laparoscopic sleeve gastrectomy (CPT 43775), is performed in a hospital outpatient setting or ambulatory surgery center. The provider removes a large portion of the stomach vertically, creating a sleeve-shaped stomach to restrict food intake. Postoperative care includes monitoring for complications, nutritional counseling, and follow-up visits to assess weight loss and improvement in comorbidities.

Coding Specifications

Modifiers:
- Modifier 22 (Increased Procedural Services): Used when the procedure requires significantly more effort or time than usual, such as in cases of complex anatomy or intraoperative complications.
- Modifier 51 (Multiple Procedures): Used when more than one surgical procedure is performed during the same operative session, such as sleeve gastrectomy with hiatal hernia repair.
