ICD-10-CM Code K65

| ICD-10 from 2011 - 2016

ICD Code K65 is a non-billable code. To code a diagnosis of this type, you must use one of the seven child codes of K65 that describes the diagnosis 'peritonitis' in more detail.

The ICD code K65 is used to code Peritonitis

Peritonitis is an inflammation of the peritoneum, the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs. Peritonitis may be localized or generalized, and may result from infection (often due to rupture of a hollow abdominal organ as may occur in abdominal trauma or inflamed appendix) or from a non-infectious process.
