ICD-10-CM Code For Disorders Of Peritoneum In Infectious Diseases Classified Elsewhere: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K67 includes peritoneal inflammations and disorders that arise as part of infectious diseases classified elsewhere, such as peritonitis associated with systemic or localized infections. These ICD-10-CM diagnosis codes are used to document clinical scenarios that capture the presence of peritoneal involvement, the infectious etiology when specified, and the severity or complications of the condition. Accurate coding within the ICD-10-CM K67 group supports proper claim adjudication and complete clinical documentation.

ICD-10-CM K67: Disorders Of Peritoneum In Infectious Diseases Classified Elsewhere Overview

This code group represents infections and inflammatory disorders of the peritoneum that occur as manifestations of infectious diseases classified in other chapters of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM). These conditions target the peritoneal lining and adjacent retroperitoneal structures and may reflect systemic or localized infectious processes. Accurate coding is important for complete clinical documentation and can affect reimbursement through proper reporting of diagnosis complexity.

ICD-10-CM K67: Disorders Of Peritoneum In Infectious Diseases Classified Elsewhere Overview

When to Use

Use a code from this group when clinical documentation indicates peritoneal inflammation or infection that is directly associated with an infectious disease listed elsewhere in ICD-10-CM. These codes are appropriate when the peritoneal condition is a sequela or specific manifestation of another documented infectious diagnosis.

DRG Codes

DRG Code	Description
371	Major Gastrointestinal Disorders and Peritoneal Infections with MCC

791	Prematurity with Major Problems
793	Full Term Neonate with Major Problems

Typical Clinical Scenarios

An adult patient presents to the emergency department with acute severe abdominal pain, fever, and signs of sepsis after a recent intra-abdominal infection (e.g., diverticulitis) or abdominal surgery. Imaging demonstrates diffuse peritoneal inflammation and the clinician documents peritoneal involvement as part of an infectious process originating elsewhere; a diagnosis from this group is assigned to capture peritoneal inflammatory disease in the setting of that infection. Typical codes: K67
An immunocompromised patient with a known chronic intra-abdominal infection (such as tuberculosis or chronic pelvic inflammatory disease) is evaluated for progressive abdominal distension, low-grade fever, and persistent abdominal tenderness; workup shows ongoing peritoneal inflammation related to the underlying infectious disease. A code from this group is used to record the chronic or subacute peritoneal disorder caused by the established infectious condition. Typical codes: K67
A hospitalized postoperative patient develops worsening abdominal pain, leukocytosis, and peritoneal signs several days after a bowel perforation repair; operative findings note purulent peritonitis as a complication of the primary infectious process. The peritoneal disorder is coded from this group to reflect the complication of an infectious disease affecting the peritoneum. Typical codes: K67
