CPT 00790: Anesthesia for Upper Abdominal Intraperitoneal Procedures
CPT code 00790 designates anesthesia for intraperitoneal procedures in the upper abdomen, including laparoscopic operations, when no other anesthesia code applies. This code captures anesthesia work accompanying a range of upper abdominal surgeries and is relevant for national billing, coding consistency, and procedure-level analysis because it addresses cases that fall outside more specific anesthesia codes. Key payers included in the review are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise clinical framing of when CPT code 00790 is used, how it maps to typical operative settings, and the common surgical contexts where it applies (for example, laparoscopic cholecystectomy, appendectomy, colectomy, hernia repair, and adhesiolysis). The publication also summarizes payer coverage considerations, typical sites of service, related surgical procedures, and guidance on clinical context and coding relationships. This overview is intended for clinicians, coding professionals, and health policy analysts seeking a clear national-level description of the code’s clinical scope and billing significance. Data not available in the input is explicitly noted where applicable.

Billing Code Overview
CPT code 00790 describes anesthesia services provided for intraperitoneal procedures in the upper abdomen, including laparoscopy, not otherwise specified by other anesthesia codes. The service type is anesthesia for upper abdominal intraperitoneal surgery (including laparoscopic approaches). The typical site of service is operating room or surgical suite where laparoscopic or open upper abdominal intraperitoneal procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to the emergency department with acute right lower quadrant abdominal pain, nausea, and low-grade fever. Imaging and clinical exam support a diagnosis of acute appendicitis (K35.80), and the surgical team schedules a laparoscopic appendectomy. The anesthesia provider (anesthesiologist or certified registered nurse anesthetist) evaluates the patient preoperatively, documents airway assessment, ASA physical status, informed anesthesia plan, and obtains consent. General endotracheal anesthesia is induced in the operating room for an intraperitoneal laparoscopic procedure in the upper abdomen. Intraoperative management includes induction, airway control, maintenance of anesthesia, hemodynamic monitoring, fluid management, and postoperative emergence and handoff to PACU staff. The anesthesia service is reported with 00790 when the intraperitoneal upper abdominal laparoscopy is not otherwise specified by a more specific anesthesia code. Typical perioperative documentation includes start and stop times for anesthesia, modifiers as applicable, and any unusual events (e.g., difficult airway, intraoperative complications).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia involves substantially greater effort, time, or complexity than typical for 00790, with supporting documentation of increased work. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for a procedure that usually does not require it (e.g., converted open cases requiring deeper anesthesia). |
50 | Bilateral procedure | Use when bilateral intraperitoneal procedures are performed and payer rules accept modifier 50 on anesthesia claims. |
52 | Reduced services | Use when the planned procedure is partially reduced or incomplete but anesthesia was still provided (e.g., aborted procedure). |
53 | Discontinued procedure | Use when the procedure is terminated after induction of anesthesia and documentation supports discontinuation for patient-related reasons. |
59 | Distinct procedural service | Use to indicate a distinct procedural service when multiple separate services require separate anesthesia consideration per payer guidance. |
62 | Two surgeons | Use when two surgeons perform distinct portions of the procedure concurrently and documentation supports shared surgical responsibilities impacting anesthesia management. |
76 | Repeat procedure by same physician | Use when the same anesthesiology team repeats the anesthesia service later the same day for the same patient. |
77 | Repeat procedure by another physician | Use when a different anesthesia provider repeats the service later the same day. |
78 | Unplanned return to operating/procedural room | Use when the patient returns to the OR for a related procedure requiring additional anesthesia within the global period. |
AA | Anesthesia services performed personally by anesthesiologist | Use when the attending anesthesiologist personally performs the anesthesia service. |
AD | Medical supervision by anesthesiologist; more than four concurrent anesthesia procedures | Use when the anesthesiologist supervises more than four concurrent cases as defined by payer rules. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist service for anesthesia | Use when anesthesia services are performed by or under supervision consistent with AS reporting rules. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals | Use when the anesthesiologist medically directs multiple concurrent anesthesia procedures per CMS guidelines. |
QS | Monitored anesthesia care service | Use when the service provided meets criteria for monitored anesthesia care rather than general anesthesia and payer allows QS on the claim. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Board-certified anesthesiologists who most commonly report 00790 when appropriate. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs provide and document anesthesia services under institutional and payer rules; may report under supervision or independently per state law. |
207RA0401X | Anesthesiology Assistant | Anesthesiology assistants participate in delivery of anesthesia under anesthesiologist direction; billing and supervision rules vary by payer. |
