CPT 00794: Anesthesia for Partial or Total Pancreatectomy
CPT code 00794 represents anesthesia services for partial or total pancreatectomy, including complex procedures such as the Whipple resection and laparoscopic approaches. This code captures anesthetic management for major pancreatic resections, which are high-acuity abdominal operations with significant perioperative risk and resource needs. Nationally, accurate coding for these procedures affects procedural classification, quality measurement, and appropriate payment for anesthesia care during major hepatopancreatobiliary surgery.
Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise review of the clinical context for anesthesia billing in pancreatic surgery, typical sites where the service is delivered, common coding relationships to nearby anesthesia codes, and the payer landscape covered. The publication also provides benchmarks and policy-relevant discussion about coding alignment for complex abdominal anesthesia, clarity on inclusion of laparoscopic approaches, and implications for billing practice management. The content is intended to help billing staff, anesthesiology clinicians, and healthcare policy analysts understand how 00794 is used and where it sits among related anesthesia codes for major hepatic and pancreatic procedures.

Billing Code Overview
CPT code 00794 describes anesthesia services provided for patients undergoing partial or total pancreatectomy, including procedures such as the Whipple procedure (resection of the pancreatic head with adjacent structures and reconstruction). The description explicitly includes laparoscopic approaches.

Service type: Anesthesia services for major abdominal pancreatic surgery
-
Typical site of service: Operating room or surgical suite in an inpatient or ambulatory surgical center setting
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of chronic pancreatitis and a malignant mass in the head of the pancreas is scheduled for a partial pancreatectomy via an open Whipple procedure. Preoperative evaluation includes anesthetic assessment, airway evaluation, review of comorbidities (cardiovascular disease, diabetes, coagulopathy), and optimization of glucose and electrolyte status. The patient is brought to the operating room, monitored with standard ASA monitors, large-bore IV access, and arterial line for continuous blood pressure monitoring. General endotracheal anesthesia is induced; central venous access is obtained for fluid and vasoactive medication management. Intraoperative care includes maintenance of anesthesia, blood conservation strategies, hemodynamic support during major resection and reconstruction, management of significant visceral stimulation and potential massive hemorrhage, and smooth emergence to facilitate postoperative respiratory function. Postoperative handoff to the surgical and critical care teams documents anesthetic agents, blood loss, transfusions, hemodynamic events, and recommendations for postoperative pain control and ventilatory support. This anesthesia service corresponds to 00794 and applies to both open and laparoscopic partial or total pancreatectomy, including Whipple procedures.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia complexity or duration is substantially greater than usual for 00794 and documentation supports unusual circumstances. |
23 | Unusual anesthesia | Use when general anesthesia is administered for a procedure that normally does not require it and documentation supports the medical necessity. |
52 | Reduced services | Use when the planned anesthetic service for 00794 is partially reduced or not completed as planned. |
53 | Discontinued procedure | Use when the anesthetic is terminated because of extenuating circumstances or patient condition before completion of 00794. |
54 | Surgical care only | Use when the surgeon provides only the surgical services and another clinician provides anesthesia (rarely applied to anesthesia reporting; included per input list for completeness where applicable to surgical billing). |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during complex pancreatic resection; impacts surgical but may be reported when anesthesia documentation notes dual-surgeon complexity. |
78 | Unplanned return to operating room following initial procedure for a related procedure during the post-op period | Use when the patient returns to the OR for a related pancreatic surgical issue and additional anesthesia services are provided. |
AA | Anesthesia services performed personally by anesthesiologist | Use to indicate the anesthesiologist personally performed the anesthesia for 00794. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | Use when the anesthesiologist supervises the anesthetist team for multiple concurrent anesthetics including 00794. |
AS | Physician assistant or nurse practitioner service | Use when an advanced practice clinician provides aspects of perioperative care under supervision alongside 00794 (applies to Perioperative E/M or other services when allowed). |
QK | Medical direction of two, three, or four CRNAs/AA by a physician | Use when the anesthesiologist medically directs multiple CRNAs during cases including 00794. |
QS | Monitored anesthesia care service | Use if the anesthetic provided is MAC rather than general anesthesia and documentation supports MAC for components of pancreatic surgery (rare for major pancreatectomy). |
QX | CRNA service with medical direction by physician | Use when a CRNA furnishes anesthesia for 00794 under the medical direction of a physician. |
QY | Medical direction of one CRNA by a physician | Use when the anesthesiologist directs a single CRNA during 00794. |
QZ | CRNA service without medical direction by a physician | Use when a CRNA furnishes the anesthesia for 00794 without physician direction, where payer policy permits. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physician anesthesiologists who perform and direct anesthesia for 00794. |
207LA0401X | Anesthesiology Assistant | Anesthesiology assistants supporting perioperative anesthesia management for pancreatectomy. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs providing anesthesia services for pancreatectomy under appropriate supervision or direction. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
H25.9 | Unspecified age-related cataract | Cataract codes provided in input are not clinically related to pancreatectomy; listed per input. They may be present as unrelated comorbid ophthalmologic diagnoses in the medical record. |
H26.9 | Unspecified cataract | See above; an unrelated ophthalmic diagnosis that may appear in problem lists but does not drive anesthesia coding for 00794. |
H27.00 | Aphakia, unspecified eye | Ophthalmic condition included in input; not directly related to pancreas surgery but may be listed as a comorbidity. |
H28 | Cataract in diseases classified elsewhere | Ophthalmic secondary cataract diagnosis from input; not clinically related to pancreatectomy. |
H52.4 | Presbyopia | Age-related refractive error included in input; not related to pancreatic surgery but may be part of the patient's chronic conditions. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
