Summary & Overview
CPT 49592: Initial Repair of Incarcerated or Strangulated Anterior Abdominal Hernia
CPT code 49592 denotes the initial surgical repair of one or more anterior abdominal hernias measuring less than 3 cm in total length when the hernias are incarcerated or strangulated. The code covers any operative approach and permits implantation of mesh or another prosthesis. This code is important nationally because incarcerated and strangulated hernias represent surgical urgencies with implications for hospital resources, operative technique selection, and coding consistency across payers.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common sites of service, and payer coverage considerations. The publication summarizes benchmarking points and explains how the code is used in practice, highlights potential areas for documentation clarity, and outlines what to expect for claim processing under major national payers.
This summary provides clinicians, coders, and administrators with the essential facts needed to recognize when CPT code 49592 applies, understand its clinical urgency, and anticipate common billing scenarios. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 49592 describes the initial surgical repair of one or more anterior abdominal hernias when the total hernia length is less than 3 cm and the hernias are incarcerated or strangulated. The procedure may be performed using any operative approach and may include implantation of mesh or another prosthesis at the surgeon's discretion.
Service type: Surgical — Hernia Repair (emergent/urgent operative repair due to incarceration or strangulation)
Typical site of service: Inpatient or outpatient surgical setting, including hospital operating room or ambulatory surgical center, depending on clinical status and local practice patterns.
Clinical & Coding Specifications
Clinical Context
A 62-year-old male presents to the emergency department with acute-onset severe abdominal pain, a tender palpable bulge in the lower midline consistent with an anterior abdominal hernia, nausea, and inability to reduce the hernia at bedside. Imaging (CT abdomen) confirms a small incarcerated ventral hernia defect measuring approximately 2.0 cm with signs concerning for compromised bowel. The surgical team evaluates, obtains informed consent for operative repair, and orders preoperative labs and anesthesia clearance. In the operating room under general anesthesia, the surgeon performs an initial repair of the anterior abdominal hernia using an open approach, reduces incarcerated contents, assesses bowel viability, implants prosthetic mesh for reinforcement, and closes the incision. Postoperatively the patient is monitored in the post-anesthesia care unit and admitted for short inpatient observation for pain control and serial abdominal exams; discharge occurs within 24–48 hours if no complications arise. This workflow reflects urgent operative management for a small (<3 cm) incarcerated or strangulated anterior abdominal wall hernia corresponding to 49592.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier | Not typically appended; placeholder for systems that require a two-character default modifier |
22 | Increased procedural services | When work required is substantially greater than usual (e.g., extensive adhesiolysis for incarcerated/strangulated contents) |
23 | Unusual anesthesia | When services are performed under circumstances that require anesthesia but not normally needed for the procedure performed |
24 | Unrelated evaluation and management service by the same physician during a postoperative period | For unrelated E/M visits during global period after hernia repair |
59 | Distinct procedural service | When a different, unrelated procedure is performed at a separate anatomic site during the same operative session |
62 | Two surgeons | When two surgeons work together as primary surgeons on the procedure |
63 | Procedure performed on infants less than 4 kg | Rarely applicable; use only if patient meets weight criteria |
65 | (Not in provided list) | Data not available in the input |
66 | Surgical team approach | For team surgery when multiple surgeons provide distinct components of care |
78 | Return to the operating room for a related procedure during the global period | If reoperation is required for complication related to initial repair during the global period |
79 | Unrelated procedure or service by the same physician during the postoperative period | For unrelated operations performed during the global period |
50 | Bilateral procedure | If bilateral repairs are performed (note anatomical applicability) |
51 | Multiple procedures | When additional distinct surgical procedures are performed at the same session |
52 | Reduced services | When the service is partially reduced or eliminated at physician discretion |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207L00000X | General Surgery | Most common specialists performing open anterior abdominal hernia repairs |
| 2080P0207X | Colon & Rectal Surgery | Manages complex ventral or abdominal wall pathology and bowel assessment when incarcerated/strangulated |
| 207T00000X | Surgical Oncology | Performs abdominal wall resections/repairs when hernia is associated with tumor or complex intra-abdominal disease |
| 363L00000X | Acute Care Surgery | Provides emergency and urgent operative management for incarcerated/strangulated hernias |
| 207K00000X | Pediatric Surgery | Applies if procedure performed in pediatric patients |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
K43.2 | Incisional hernia with obstruction, without gangrene | Common diagnosis when abdominal wall hernia is incarcerated causing obstruction; may indicate urgency for 49592 repair |
K43.1 | Incisional hernia with gangrene | Indicates strangulation with compromised bowel viability; directly relevant to emergent repair and possible bowel resection |
K46.9 | Unspecified abdominal hernia without obstruction or gangrene | May be used initially when specifics are not yet documented; less specific but associated with hernia repairs |
K40.20 | Unilateral inguinal hernia, without obstruction or gangrene, with gangrene not specified | Included because inguinal hernias can present similarly; ICD guidance requires site-specific coding when applicable |
K41.9 | Femoral hernia without obstruction or gangrene | Femoral hernias can incarcerate/strangulate and may require similar urgent surgical repair approaches |
