Summary & Overview

CPT 44960: Appendectomy for Ruptured Appendix with Abscess or Peritonitis

CPT code 44960 denotes an appendectomy performed for a ruptured appendix with abscess formation or diffuse peritonitis. Nationally, this code captures a high-acuity, often emergency general surgery procedure used to manage complicated appendicitis and prevent life-threatening intra-abdominal sepsis. Accurate coding for ruptured appendicitis affects clinical documentation, hospital case mix, and reimbursement for complex surgical and inpatient care.

Key payers considered in this profile include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical description, expected site-of-service context, and the common payer landscape. The analysis highlights benchmarks for utilization and payment practices, documentation and policy considerations that influence claim adjudication, and typical clinical scenarios tied to the code.

This publication provides clinicians, coding professionals, and policy analysts with practical context for CPT code 44960: when it is used clinically, how it differs from uncomplicated appendectomy codes, and what payers commonly review for cases involving abscess or peritonitis. Data limitations are noted where input fields were not provided. The focus is national; no state-specific guidance is included.

Billing Code Overview

CPT code 44960 describes an appendectomy for ruptured (burst) appendix performed because of abscess formation or generalized peritonitis. The procedure involves removal of the appendix, a saclike structure located in the right lower quadrant at the junction of the small and large intestines, to control infection and prevent further intra-abdominal complications.

Service type: Surgical — Emergency/Acute Abdominal Surgery

Typical site of service: Inpatient hospital operating room or emergency surgical suite for patients presenting with abscess or widespread peritonitis.

Clinical & Coding Specifications

Clinical Context

A 28-year-old adult presents to the emergency department with 24–48 hours of worsening right lower quadrant abdominal pain, fever, nausea, and leukocytosis. Imaging (abdominal CT) demonstrates a ruptured appendix with periappendiceal fluid and an adjacent abscess with scattered free intraperitoneal fluid. The patient is taken emergently to the operating room for an open appendectomy for removal of a ruptured (burst) appendix due to abscess formation and localized or generalized peritonitis. The clinical workflow includes preoperative resuscitation and broad-spectrum IV antibiotics, informed consent documenting the diagnosis and need for urgent surgery, general endotracheal anesthesia, possible abdominal irrigation and drainage of abscess, control of contamination, placement of drains if indicated, and postoperative monitoring in the PACU and surgical ward with continued antibiotics and pain control. Discharge planning addresses wound care, activity restrictions, and follow-up for drain removal or wound check.
