CPT 00756: Anesthesia for Transabdominal Diaphragmatic Hernia Repair
CPT code 00756 denotes anesthesia services for transabdominal repair of a diaphragmatic hernia. This code is used when anesthesia professionals provide perioperative anesthesia care for surgical correction of a diaphragmatic discontinuity and reduction of abdominal contents through an abdominal approach. Nationally, accurate reporting of anesthesia codes such as 00756 affects billing consistency, resource allocation for perioperative care, and appropriate payment for complex intra-abdominal procedures.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of clinical context for the service, typical sites of care, common billing considerations, and related anesthesia procedure groupings. The content highlights where 00756 fits among upper abdominal anesthesia codes and what clinical scenarios commonly map to this code.
The publication provides benchmarks and comparative references to related anesthesia codes for upper abdominal procedures, clarifies clinical indications that commonly lead to its use, and summarizes payer coverage scope. The goal is to give providers, coding professionals, and policy analysts a concise reference for the clinical and billing role of CPT code 00756 across major national payers.

Billing Code Overview
CPT code 00756 describes anesthesia services provided for a patient undergoing a transabdominal repair of a diaphragmatic hernia. The procedure involves repairing a discontinuity in the respiratory diaphragm and returning protruding abdominal contents to the abdominal cavity via a transabdominal approach.
Service Type: Anesthesia for transabdominal diaphragmatic hernia repair
Typical Site of Service: Hospital operating room or surgical center
Clinical & Coding Specifications
Clinical Context
A 52-year-old female presents with progressive epigastric pain, postprandial fullness, and intermittent shortness of breath. Imaging (CT abdomen/pelvis) demonstrates a large left-sided diaphragmatic hernia with omental and small-bowel herniation into the thoracic cavity and partial bowel obstruction. Preoperative assessment identifies ASA physical status P3 due to hypertension and chronic obstructive pulmonary disease. The surgical team plans a transabdominal diaphragmatic hernia repair under general endotracheal anesthesia via an open abdominal approach to reduce herniated contents, repair the diaphragmatic defect, and place mesh as indicated.
Perioperative workflow: the patient undergoes preoperative evaluation by the anesthesiology team, airway assessment, and optimization of pulmonary status. In the operating room, standard ASA monitors are applied, rapid sequence induction is considered if gastric distention is present, and invasive monitoring (arterial line) is placed based on comorbidities. The anesthetic plan includes general anesthesia with endotracheal intubation, controlled ventilation with attention to peak airway pressures after reduction of intrathoracic contents, and hemodynamic management during potential tension physiology. Postoperative disposition is decided with the surgeon; many patients recover in a postanesthesia care unit (PACU) then to a surgical ward or intensive care unit if respiratory compromise or hemodynamic instability is anticipated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | When the anesthetic management is substantially more complex than typical for transabdominal diaphragmatic hernia repair (extensive intraoperative complications or unusually difficult management). |
23 | Unusual anesthesia | When general anesthesia is administered for a procedure that is normally performed without general anesthesia and documentation supports unexpected need for general anesthesia. |
50 | Bilateral procedure | Not commonly applicable; use if identical operative procedures are performed bilaterally during the same anesthesia encounter. |
52 | Reduced services | When the anesthetic service provided is partially reduced or aborted but still performed, with appropriate documentation. |
53 | Discontinued procedure | When anesthesia is provided but the surgical procedure is terminated due to patient condition or intraoperative event prior to completion. |
54 | Surgical care only | When the anesthesiologist provides only intraoperative anesthesia and postoperative anesthesia care is transferred to another qualified anesthetist. |
55 | Postoperative management only | When the anesthesiologist provides only postoperative pain management and recovery care, not the intraoperative anesthetic. |
62 | Two surgeons | If two surgeons are required and documented as necessary for the case complexity (e.g., general surgeon and thoracic surgeon). |
78 | Unplanned return to the operating room following initial procedure | When the patient returns to the OR for a related procedure during the global period and anesthesia is provided. |
AA | Anesthesia services furnished personally by anesthesiologist | When the billed anesthesiologist personally performs the anesthesia service. |
AD | Medical supervision by a physician: more than four concurrent anesthesia procedures | When the anesthesiologist supervises multiple concurrent CRNA procedures beyond four. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | When advanced practice providers contribute to perioperative care as allowed by payer policies (use only where appropriate). |
QK | Medical direction of two, three, or four concurrent anesthesia procedures involving CRNAs | When an anesthesiologist medically directs multiple CRNAs per CMS medical direction rules. |
QS | Monitored anesthesia care service | If monitored anesthesia care (MAC) is provided instead of general anesthesia for a portion of care (rare for this procedure). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physician anesthesiologists who provide perioperative anesthesia care for major abdominal and thoracoabdominal procedures. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who may provide or assist in anesthetic delivery under supervision or medical direction. |
207RA0401X | Anesthesiology Assistant | Anesthesiology assistants who practice under anesthesiologist supervision and assist in management of complex cases. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
K56.60 | Unspecified intestinal obstruction | Bowel obstruction can occur with herniation through the diaphragm; may necessitate reduction of incarcerated bowel during repair. |
N83.20 | Unspecified ovarian cyst | Incidental or coexisting intra-abdominal pathology; not a direct indication for diaphragmatic repair but may be present in the operative field. |
K40.90 | Unilateral inguinal hernia, without obstruction or gangrene, not specified as recurrent | Represents concurrent hernia disease; may be documented as comorbidity but is not the target of a transabdominal diaphragmatic repair. |
N20.0 | Calculus of kidney | Renal calculi are a coexisting urologic condition that may be present in the preoperative problem list; not causative for diaphragmatic hernia repair. |
K35.80 | Unspecified acute appendicitis | An acute intra-abdominal surgical diagnosis that could occur concurrently or complicate perioperative management; usually unrelated to diaphragm repair but may alter anesthesia planning if present. |
