Acute appendicitis with generalized peritonitis, with perforation and abscess
ICD-10 K35.211 is a billable code used to indicate a diagnosis of acute appendicitis with generalized peritonitis, with perforation and abscess.
K35.211 refers to acute appendicitis with generalized peritonitis, specifically with perforation and abscess formation. This condition arises when the appendix becomes inflamed, often due to obstruction, leading to increased intraluminal pressure, ischemia, and bacterial overgrowth. The inflammation can progress rapidly, resulting in perforation of the appendiceal wall, which allows intestinal contents to spill into the peritoneal cavity, causing peritonitis. Clinically, patients typically present with severe abdominal pain, fever, nausea, and vomiting. Physical examination may reveal rebound tenderness and guarding, indicating peritoneal irritation. Diagnostic imaging, such as ultrasound or CT scan, is often utilized to confirm the diagnosis and assess for complications like abscess formation. The anatomy involved includes the appendix, the cecum, and the peritoneal cavity. Disease progression can lead to systemic inflammatory response syndrome (SIRS) and sepsis if not promptly treated. Surgical intervention, usually an appendectomy, is the primary treatment, often accompanied by drainage of any abscesses. Postoperative care is crucial to monitor for complications and ensure recovery.

K35.211 specifically covers acute appendicitis that has progressed to include generalized peritonitis, perforation of the appendix, and the presence of an abscess. It is critical that the clinical documentation supports these findings.
K35.211 should be used when there is clear evidence of perforation and abscess formation in the context of acute appendicitis. Related codes, such as K35.2, should be used when there is no evidence of these complications.
Documentation must include clinical findings of acute appendicitis, imaging results confirming perforation and abscess, surgical notes detailing the procedure performed, and post-operative assessments indicating the patient's condition.
