CPT 43825: Gastrojejunostomy, Stomach to Jejunum Anastomosis

CPT code 43825 denotes a surgical gastrojejunostomy: construction of an anastomosis between the stomach and jejunum. This operative procedure is an established technique for bypassing the duodenum and is frequently used in the management of complicated duodenal ulcer disease and other indications requiring gastric diversion. Nationally, it is a relevant inpatient and outpatient surgical billing category because it spans general and bariatric surgery practices and can impact hospital surgical case mix and resource utilization.

Key payers examined in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context, coding description, and typical sites of service, alongside payer coverage considerations and commonly reported modifiers. The publication outlines how CPT code 43825 is used in surgical practice, summarizes common billing patterns, and highlights where policy updates or payer-specific documentation requirements may affect coding and reimbursement workflows.

This national summary is intended to orient clinicians, coding professionals, and administrators to the procedure represented by CPT code 43825, what to expect across major payers, and which operational and documentation topics to review when handling cases that involve gastrojejunostomy.

Billing Code Overview

CPT code 43825 describes a surgical procedure in which the provider constructs an anastomosis between the stomach and the jejunum. The operation establishes a direct gastrointestinal connection (gastrojejunostomy) and is commonly performed for conditions such as complicated duodenal ulcer disease and other indications requiring gastric diversion.

Service type: Surgical open or laparoscopic gastrointestinal anastomosis (gastrojejunostomy)
Typical site of service: Hospital inpatient or outpatient surgical setting, including operating room or ambulatory surgery center

Clinical & Coding Specifications

Clinical Context

A 62-year-old male with a history of complicated peptic ulcer disease presents with persistent epigastric pain, vomiting, and weight loss despite medical therapy. Endoscopy demonstrates gastric outlet obstruction related to chronic duodenal ulceration and pyloric channel scarring. After preoperative evaluation and medical optimization, the surgical team performs a gastrojejunostomy to bypass the obstructed proximal duodenum and restore enteric continuity. The operation is performed in an operating room under general anesthesia with endotracheal intubation. The typical clinical workflow includes preoperative consent and testing, induction of anesthesia, open or laparoscopic creation of the gastric-to-jejunal anastomosis, intraoperative assessment for hemostasis and leak testing, placement of drains if indicated, postoperative monitoring in the PACU and surgical ward, and follow-up for wound care and nutritional progression. Concurrent procedures such as vagotomy for ulcer disease or feeding tube placement may be performed depending on intraoperative findings and patient needs.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier/Not a real CMS modifier (placeholder)	Data not applicable — not typically used as an explicit modifier code in claims.
`11`	Office/Other Outpatient Service (hypothetical local use)	Not standard CMS modifier; if present in payer systems, used to denote primary service — verify payer-specific guidance.
`22`	Increased procedural services	Used when the gastrojejunostomy required substantially greater time, effort, or complexity than usual.
`23`	Unusual anesthesia — with general anesthesia exemption	Applied when general anesthesia is contraindicated and unusual circumstances required additional anesthesia services (rare for this code).
`26`	Professional component	Use if reporting only the surgeon's professional component separate from facility technical component (rare for operative codes billed by facility).
`50`	Bilateral procedure	Not typically applicable for `43825` as the procedure is not bilateral; do not use unless payer-specific bilateral logic applies.
`51`	Multiple procedures	Applied when `43825` is billed with additional significant unrelated procedures during the same operative session to indicate multiple procedures were performed.
`52`	Reduced services	Use when the procedure was partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Applied if the gastrojejunostomy was started but discontinued due to extenuating circumstances.
`62`	Two surgeons — multiple surgeon requirement	Use when another surgeon of different specialty provides distinct surgical services and documentation supports a co-surgeon scenario.
`63`	Procedure performed on infants less than 4 kg	Not typically relevant; generally not used for adult `43825`.
`66`	Surgical team (team surgery)	Use if multiple surgeons functioned as an organized surgical team for a complex case.
`78`	Unplanned return to the operating room following initial procedure for a related procedure during the postoperative period	Use when the patient returns to OR for a complication directly related to the gastrojejunostomy.
`80`	Assistant surgeon	Use when a surgical assistant (physician) assists the primary surgeon and the payer requires reporting.

Taxonomy Code	Specialty	Notes
`408600000X`	General Surgery	General surgeons commonly perform gastrojejunostomy for obstructive or ulcer disease indications.
`208100000X`	Colon & Rectal Surgery	Colorectal surgeons may perform upper GI bypass procedures in complex abdominal surgical practices.
`207L00000X`	Vascular Surgery	Occasionally involved if vascular complications or reconstruction are required; less common.
`207K00000X`	Thoracic Surgery	May be involved when combined thoracoabdominal procedures are required.
`200000000X`	Surgery (General) — broad taxonomy	Used by hospitals and surgicalists who perform open and laparoscopic gastric bypass/ bypass operations.
