CPT 00840: Anesthesia for Lower Abdominal Intraperitoneal Procedures, Including Laparoscopy
CPT code 00840 denotes anesthesia for intraperitoneal procedures in the lower abdomen, including laparoscopic approaches when no other anesthesia code is applicable. This code captures perioperative anesthesia services for a broad range of lower abdominal intraperitoneal surgeries, making it a key procedure code for anesthesia billing and national practice benchmarking. It is relevant for hospitals, ambulatory surgical centers, anesthesiology groups, and payers managing claims for common procedures such as appendectomy, adnexal surgery, cholecystectomy-related intraperitoneal work, and other lower abdominal laparoscopic interventions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of clinical contexts where 00840 applies, common associated diagnoses and related surgical procedure codes, and typical payer considerations. The publication outlines where 00840 fits among anesthesia service codes, highlights situations that commonly trigger use of this code (lower abdominal intraperitoneal and laparoscopic procedures not otherwise specified), and identifies related surgical CPT codes often appearing on the same claim.
This summary provides a national perspective on code usage and clinical scope. The report equips coding and revenue cycle teams, anesthesiology clinicians, and policy analysts with concise context about when 00840 is applicable, typical sites of service, and the payer landscape addressed in the analysis.

Billing Code Overview
CPT code 00840 describes anesthesia services for intraperitoneal procedures in the lower abdomen, including laparoscopy, when no other anesthesia code applies. The service type is anesthesia for lower abdominal intraperitoneal surgery (including laparoscopic approaches). Typical site of service is operating room or ambulatory surgical center for lower abdominal laparoscopic or open intraperitoneal procedures.
Clinical & Coding Specifications
Clinical Context
A 38-year-old female presents to the emergency department with acute lower abdominal pain, nausea, and distension. Initial evaluation including abdominal exam and CT imaging suggests possible acute appendicitis with hemoperitoneum and an adnexal mass; differential includes obstructive ileus. The surgical team recommends diagnostic laparoscopy with possible appendectomy, evaluation of adnexal structures, and control of intra-abdominal bleeding. The anesthesia team documents perioperative assessment, obtains informed consent for general anesthesia with endotracheal intubation, manages induction and maintenance of anesthesia for an intraperitoneal lower abdominal laparoscopic procedure, and provides intraoperative hemodynamic and airway management. Postoperative handoff is completed to PACU staff with postoperative analgesia and nausea management documented.
This clinical workflow aligns with anesthesia CPT 00840 for intraperitoneal procedures in the lower abdomen including laparoscopy, where the anesthesiologist bills for anesthesia services covering preoperative evaluation, induction, intraoperative management, and immediate postoperative care until transfer to PACU.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the anesthesia service requires substantially greater resources or complexity than typical for 00840 (document justification). |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary but not usually required for the procedure (document why). |
50 | Bilateral procedure | Use if bilateral lower abdominal intraperitoneal procedures are performed and bilateral reporting is appropriate. |
52 | Reduced services | Use when the planned procedure is substantially reduced or not completed but anesthesia was provided (document reason). |
53 | Discontinued procedure | Use when the procedure is terminated for patient-related or intraoperative reasons after anesthesia initiation. |
59 | Distinct procedural service | Use to indicate a separate/anatomic or distinct procedure when reporting multiple services on the same day. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons on the same procedure requiring shared operative responsibilities. |
76 | Repeat procedure by same physician | Use when the anesthesia service is repeated by the same anesthesiologist during the global period. |
77 | Repeat procedure by another physician | Use when another anesthesiologist repeats the anesthesia service during the global period. |
91 | Repeat clinical diagnostic laboratory test | Use when repeat diagnostic testing relevant to anesthesia management is performed (e.g., repeat arterial blood gas) and payer requires modifier for repeats. |
AA | Anesthesia services performed personally by anesthesiologist | Use when the physician anesthesiologist personally performs the anesthesia for 00840. |
AD | Medical supervision by anesthesiologist; more than four concurrent anesthesia procedures | Use when the anesthesiologist medically directs two to four or more concurrent anesthesia cases per payer rules (document supervision level). |
QK | Medical direction of two to four concurrent anesthesia procedures involving qualified individuals | Use when the anesthesiologist medically directs qualified CRNAs for concurrent cases per payer rules. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary specialty billing anesthesia services for intraperitoneal laparoscopy 00840. |
207LA0401X | Pain Medicine (Anesthesiology) | Relevant when anesthesiologist with pain subspecialty provides perioperative analgesia planning or regional techniques. |
207LP2900X | Pediatric Anesthesiology | Use when pediatric patients undergo lower abdominal intraperitoneal laparoscopic procedures and pediatric anesthesiology expertise is required. |
