CPT 00740: Anesthesia for Upper Gastrointestinal Endoscopic Procedures, Proximal to Duodenum
CPT code 00740 denotes anesthesia for upper gastrointestinal endoscopic procedures when the endoscope is introduced proximal to the duodenum. This code captures the anesthetic services associated with upper endoscopy and related diagnostic or therapeutic interventions, a common component of gastroenterology care pathways. Accurate use of this code is important for clinical documentation, payer adjudication, and national procedure utilization monitoring.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical contexts where 00740 applies, comparisons to related anesthesia codes for endoscopic procedures, and benchmarks for service settings and typical practice patterns. The publication covers coding relationships to upper GI endoscopic procedures, expected sites of service, and the common procedural scenarios that drive use of 00740.
This summary is intended to inform health system coders, anesthesiology clinicians, and payer policy teams about the scope and typical application of CPT code 00740, the clinical encounters it represents, and where it fits within anesthesia coding for endoscopic services.

Billing Code Overview
CPT code 00740 describes anesthesia for upper gastrointestinal endoscopic procedures with the endoscope introduced proximal to the duodenum. The service encompasses anesthesia care provided during diagnostic and therapeutic endoscopic interventions in the upper GI tract, including procedures such as esophagoscopy and upper endoscopy performed via the oral or transoral route.
Service Type: Anesthesia for upper gastrointestinal endoscopic procedures
Typical Site of Service: Endoscopy suite, ambulatory surgery center, or hospital operating room
Clinical & Coding Specifications
Clinical Context
A 55-year-old patient is scheduled for an upper gastrointestinal endoscopic procedure (esophagogastroduodenoscopy) for evaluation of persistent upper abdominal pain and suspected peptic ulcer disease. The procedure requires general anesthesia or deep sedation with airway management because the endoscope will be introduced proximal to the duodenum. The perioperative workflow includes pre-anesthesia evaluation (medical history, airway assessment, medication reconciliation, and consent), intraoperative anesthetic induction and airway placement as indicated (endotracheal tube or laryngeal mask airway), continuous physiologic monitoring (ECG, pulse oximetry, noninvasive blood pressure, capnography), anesthetic maintenance and adjustments for procedural stimulation, and post-anesthesia recovery monitoring with discharge criteria documented. Typical site of service is an endoscopy suite, ambulatory surgery center, or hospital operating room. Common clinical indications for use of 00740 include diagnostic esophagoscopy with biopsy, therapeutic interventions such as band ligation or variceal therapy, or when the patient’s comorbidity, airway risk, or anticipated procedural complexity necessitates anesthesiologist-administered anesthesia.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the anesthesia service involved substantially greater work or complexity than typical for the procedure (document justification). |
23 | Unusual anesthesia | Use when general anesthesia is administered for a procedure that is normally performed with local or moderate sedation, and documentation supports unusual circumstances. |
24 | Unrelated E/M service by same physician during postoperative period | Use when an unrelated evaluation and management service is provided during the global postoperative period. |
25 | Significant, separately identifiable E/M service on the same day | Use when a significant E/M service is provided on the same day as the procedure and is documented separately. |
52 | Reduced services | Use when the service provided is partially reduced or not completed as documented. |
53 | Discontinued procedure | Use when the planned anesthesia/procedure is started but discontinued due to extenuating circumstances. |
57 | Decision for surgery | Use when the E/M service resulted in the initial decision to perform surgery (applicable to preoperative encounter coding). |
59 | Distinct procedural service | Use to indicate a procedure or service was distinct or independent from other services performed on the same day (use with caution and appropriate documentation). |
76 | Repeat procedure by same physician | Use when a procedure is repeated subsequent to the original on the same day by the same physician. |
77 | Repeat procedure by another physician | Use when a procedure is repeated by a different physician on the same day. |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use for unplanned return to the OR for related anesthesia services. |
80 | Assistant surgeon | Use when an assistant surgeon is required (billing relationship to surgery, not anesthesia). |
AA | Anesthesia services performed personally by anesthesiologist | Use when the anesthesiologist personally performs the anesthesia service. |
QX | CRNA service with medical direction by a physician | Use when a certified registered nurse anesthetist provides services under medical direction by a physician. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physicians who provide physician-directed anesthesia care for upper GI endoscopic procedures. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who may deliver anesthesia services in the endoscopy suite or ambulatory setting under or without physician direction per state rules. |
207LA0401X | Pain Medicine (Anesthesiology) | Anesthesiologists with pain medicine specialty who may be involved in perioperative pain management planning for complex patients. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
K35.80 | Acute appendicitis without perforation or gangrene | Not directly related to upper GI endoscopy; may appear in the patient problem list but is not an indication for 00740. |
K40.90 | Unilateral inguinal hernia, without obstruction or gangrene, not specified as recurrent | Not an indication for upper GI endoscopy; may be a comorbid condition documented during pre-anesthesia evaluation. |
K80.20 | Calculus of gallbladder without cholecystitis without obstruction | May coexist with upper abdominal pain prompting diagnostic upper endoscopy; not a direct indication for 00740. |
K85.90 | Acute pancreatitis, unspecified | Upper abdominal pain from pancreatitis can prompt endoscopic evaluation (e.g., to assess for biliary obstruction); anesthesia 00740 applies when endoscope is introduced proximal to duodenum. |
K63.5 | Polyp of colon | Colonic polyp is generally evaluated with lower endoscopy; listed here as a comorbid diagnosis but not a typical indication for 00740. |
