Summary & Overview
CPT 43770: Laparoscopic Adjustable Gastric Band Placement
CPT code 43770 denotes laparoscopic placement of an adjustable gastric band to restrict stomach size for treatment of morbid obesity. As a commonly billed bariatric surgery code, it represents a surgical alternative focused on restrictive weight-loss mechanisms and is relevant for national coverage policies, utilization management, and surgical quality programs. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of clinical intent and site-of-service implications, typical payer coverage considerations, and benchmarking context for utilization and payment trends. The publication summarizes where CPT code 43770 fits in the spectrum of bariatric interventions, outlines common billing modifiers when present (input lists provided), and highlights the operational settings most associated with the procedure. It also points to areas of policy attention for payers and health systems, such as prior authorization, medical necessity criteria for morbid obesity, and post-operative care pathways.
Data not available in the input for some fields (detailed payer-specific rates, associated taxonomies, and ICD-10 diagnosis lists) is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with morbid obesity and failed conservative weight-loss measures presents for a planned laparoscopic adjustable gastric banding procedure. Preoperative evaluation includes BMI assessment, nutritional and behavioral counseling, cardiopulmonary risk stratification, and clearance from the multidisciplinary bariatric team. On the day of service the patient is admitted to the ambulatory surgical center or hospital operating room. General endotracheal anesthesia is induced. The surgeon creates laparoscopic ports, performs intra-abdominal inspection, and places an adjustable silicone band around the proximal stomach to create a small gastric pouch and restrict oral intake. The port for postoperative band adjustments is secured to the abdominal wall. Typical intraoperative workflow includes laparoscopic access, band placement, confirmation of correct position and leak check, hemostasis, and port fixation. Postoperative workflow includes recovery in PACU, pain control, early ambulation, discharge instructions regarding diet progression and band adjustment schedule, and scheduling of follow-up visits for band inflation/deflation and nutritional monitoring. Common payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare, with prior authorization often required.
