CPT 49900: Resuturing Abdominal Incision for Wound Dehiscence

CPT code 49900 covers the operative resuturing of an abdominal incision that has dehisced, ruptured, or allowed evisceration of internal organs. Nationally, this code represents urgent or emergent surgical management of wound failure after abdominal operations and is clinically significant for acute surgical care pathways, hospital resource allocation, and post-operative complication reporting. Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for use of 49900, common service settings, and what typical claims for this procedure reflect about care intensity. The publication summarizes benchmark considerations for payers listed above, notes common billing modifiers and related administrative issues (where provided), and highlights clinical factors that drive utilization and cost in national practice. Data not available in the input is identified explicitly where applicable. This summary is intended for health policy analysts, hospital billing managers, and clinical leaders seeking a concise reference on the purpose and national relevance of CPT code 49900.

Billing Code Overview

CPT code 49900 describes the resuturing of an abdominal surgical incision after wound dehiscence, rupture, or evisceration with protrusion of internal organs. This procedure involves surgical reapproximation of the abdominal wall and closure of the fascial and skin layers to manage a compromised or open laparotomy incision.

Service type: Surgical wound management / abdominal reclosure
Typical site of service: Operating room or other surgical suite where operative abdominal procedures are performed

Data not available in the input for payerspecific coverage, associated taxonomies, and ICD-10 diagnoses.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 62-year-old postoperative patient who returns to the emergency department with acute abdominal wound dehiscence after an open exploratory laparotomy performed 7 days earlier for bowel obstruction. The patient reports serosanguinous drainage from the incision, increased pain, and visible separation of the incision edges, with possible protrusion of bowel. On exam there is partial evisceration of small bowel through the midline incision. The clinical workflow begins with emergency stabilization, wound assessment, broad-spectrum antibiotics as indicated, and imaging if needed to evaluate intra-abdominal involvement. The surgical team prepares for urgent return to the operating room for wound exploration and formal resuturing of the dehisced abdominal incision under anesthesia. Intraoperative steps include assessment for contamination or necrotic tissue, irrigation, reduction of eviscerated contents, possible revision of fascial closure, layered soft-tissue closure, and appropriate drains if indicated. Postoperative management includes monitoring for infection, wound care, pain control, and discharge planning with outpatient wound follow-up. Typical site of service is the hospital operating room (inpatient or emergency surgical setting). The service type is urgent/emergent open surgical wound repair for abdominal wound dehiscence with or without evisceration.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when the work required is substantially greater than usual for this procedure (e.g., extensive debridement, dense adhesions, contaminated field).
`23`	Unusual anesthesia	Use when general anesthesia is medically contraindicated and an unusual type of anesthesia was required for the procedure.
`24`	Data not available in the input.	Data not available in the input.
`50`	Bilateral procedure	Rarely applicable; use only if symmetrical bilateral abdominal wall repairs are performed in the same operative session.
`51`	Multiple procedures	Use when other distinct procedures are performed during the same operative session in addition to the resuturing.
`52`	Reduced services	Use when the procedure was partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the procedure was started but terminated due to extenuating circumstances.
`62`	Two surgeons	Use when two surgeons with distinct skills perform portions of the operation together.
`66`	Surgical team	Use when a surgical team (more than two surgeons) is documented due to complexity.
`78`	Return to OR for related procedure during postoperative period	Use when the patient returns to the operating room for a related procedure for a complication of the initial surgery.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during the global period.
`80`	Assistant surgeon	Use when an assistant at surgery (physician) is documented.
`81`	Minimum assistant surgeon	Use when a minimum assistant is documented.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist	Use when a qualified non-physician practitioner performs services as indicated by payer rules.
