2025 ICD-10-CM code K65.0
Generalized acute peritonitis.
Medical necessity for treatment of generalized acute peritonitis is usually straightforward due to the life-threatening nature of the condition. Treatment, which may include antibiotics, surgery, and supportive care, is necessary to resolve the infection and prevent complications.
Diagnosis and treatment of peritonitis often involves a multidisciplinary team including general surgeons, infectious disease specialists, and critical care specialists if the patient is unstable.
In simple words: Generalized acute peritonitis is an inflammation of the peritoneum, the lining of the abdominal cavity.It's often caused by infection and can be serious.
Generalized acute peritonitis. Includes: Abscess of abdominopelvic, mesenteric, omentum, peritoneum, retrocaecal, retroperitoneal, subdiaphragmatic, subhepatic, or subphrenic regions.Acute peritonitis: generalized, pelvic (male), subphrenic, or suppurative.
Example 1: A patient presents with severe abdominal pain, fever, and rebound tenderness. Imaging reveals free fluid in the abdomen and signs of inflammation. The patient is diagnosed with generalized acute peritonitis, likely secondary to a ruptured appendix., A patient undergoing peritoneal dialysis develops abdominal pain, cloudy dialysis effluent, and fever. Cultures confirm bacterial infection, and the patient is diagnosed with generalized acute peritonitis related to the dialysis procedure., A patient with a history of diverticulitis experiences sudden onset abdominal pain and distension, with signs of sepsis.A diagnosis of generalized acute peritonitis due to perforated diverticulitis is made.
Documentation should include the location and extent of the peritonitis, the underlying cause if known, and the severity of the infection. Imaging findings, laboratory results (such as WBC count and cultures), and clinical findings (such as fever, abdominal pain, and rebound tenderness) should be clearly documented.
