Summary & Overview
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 , with supporting documentation of increased work. |
