CPT 00700: Anesthesia for Upper Anterior Abdominal Wall Procedures
CPT code 00700 captures anesthesia services for procedures on the upper anterior abdominal wall. This code is used to bill perioperative anesthesia care provided during surgical repairs or interventions affecting the upper abdomen. Nationally, accurate use of this code matters for procedure-level anesthesia reporting, resource allocation, and claims adjudication across inpatient and outpatient surgical settings.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical context for 00700, typical sites of service, common associated surgical procedures, and how the code relates to anesthesia service lines.

Billing Code Overview
CPT code 00700 describes anesthesia services for procedures on the upper anterior abdominal wall, not otherwise specified. The service represents perioperative anesthesia care provided by an anesthesiologist or certified registered nurse anesthetist for surgical procedures involving the upper portion of the abdominal wall.
Service type: Anesthesia for upper anterior abdominal wall procedures
Typical site of service: Operating room or ambulatory surgical center, where upper anterior abdominal wall surgical procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 46-year-old male presents to the ambulatory surgery center with a symptomatic right-sided inguinal bulge and intermittent pain. Physical exam and ultrasound confirm a reducible unilateral inguinal hernia (K40.90). The patient has routine preoperative evaluation by the anesthesia team, ASA class P2, and is scheduled for an open elective inguinal hernia repair (49505) under general anesthesia with a peripheral nerve block for postoperative analgesia. The clinical workflow includes pre-anesthesia assessment, informed consent for anesthesia services, induction of general anesthesia in the operating room, intraoperative anesthetic management while the surgeon repairs the hernia on the upper anterior abdominal wall, emergence and recovery in the PACU, and discharge from the ambulatory facility when recovery criteria are met. Documentation includes anesthesia start and end times, airway management, intraoperative monitoring, anesthetic agents, regional block details if performed, and any modifier-applicable circumstances (for example, unusual procedural difficulty or patient-specific factors).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the anesthesia services required substantially greater effort due to unusual circumstances documented in the record (e.g., extensive comorbidities or prolonged difficult anesthesia management). |
23 | Unusual anesthesia | Use when medically necessary anesthesia is provided for a procedure that usually requires only local or no anesthesia (rare for open hernia repair if local would normally suffice). |
50 | Bilateral procedure | Use when truly bilateral surgical procedures are performed on the upper anterior abdominal wall during the same anesthetic. |
52 | Reduced services | Use when the planned anesthesia service is partially reduced or not completed as documented (e.g., abbreviated anesthetic due to intraoperative cancellation). |
53 | Discontinued procedure | Use when the surgical procedure is terminated after anesthesia has begun and the anesthesia service provided corresponds to a discontinued operative procedure. |
54 | Surgical care only | Use when the anesthesiologist’s role is limited to preoperative and intraoperative care and post-anesthesia management is transferred to another clinician. |
55 | Postoperative management only | Use when the anesthesiologist provides only postoperative pain management or follow-up, not the intraoperative service. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons and this impacts anesthetic planning or documentation complexity. |
77 | Repeat procedure by another physician | Use when another anesthesiologist repeats the anesthesia service for the same patient during the operative session. |
78 | Unplanned return to the operating room by the same physician following initial procedure for a related procedure during the global period | Use when the patient returns to the OR emergently for a related repair requiring additional anesthesia within the postoperative period. |
AA | Anesthesia service performed personally by anesthesiologist | Use when an MD/DO anesthesiologist personally performs the anesthesia service. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | Use when the physician supervises an anesthetist managing multiple concurrent cases beyond four. |
QK | Medical direction of two, three, or four certified registered nurse anesthetists (CRNAs) | Use when the physician medically directs multiple CRNAs for concurrent cases. |
QS | Monitored anesthesia care service | Use when the service rendered is monitored anesthesia care rather than general or regional anesthesia. |
XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | Use when an additional anesthesia encounter is distinct and separate from the primary anesthetic session. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physicians who personally provide or supervise anesthesia services for abdominal wall procedures. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who deliver anesthesia in ambulatory and inpatient settings for hernia repairs. |
207LA0401X | Pain Medicine (Anesthesiology) | Specialists who may provide perioperative regional blocks or complex analgesia planning for ventral or diaphragmatic hernia cases. |

K41.90 | Unilateral femoral hernia, without obstruction or gangrene, not specified as recurrent | Femoral hernias present as upper anterior abdominal wall groin defects requiring surgical repair and anesthesia services. |
K42.9 | Umbilical hernia without obstruction or gangrene | Umbilical hernia repair involves the anterior abdominal wall and uses similar anesthetic approaches covered by this anesthesia code. |
K43.9 | Ventral hernia without obstruction or gangrene | Ventral hernia repairs on the anterior abdominal wall are within the scope of procedures for which this anesthesia code is billed. |
K44.9 | Diaphragmatic hernia without obstruction or gangrene | Diaphragmatic hernia repair may involve the upper anterior abdominal wall region and necessitate anesthesia services described by this code. |
