What This Code Means

Inflammation of the peritoneum caused by bile leaking into the abdominal cavity, typically from a perforated gallbladder or bile duct.

Coding Tips

•Verify the source of bile leakage and code the underlying condition separately
•Distinguish from other causes of peritonitis to ensure accurate coding

Clinical Significance

K65.3 represents choleperitonitis, inflammation of the peritoneum caused by bile leaking into the peritoneal cavity, typically from gallbladder perforation or bile duct injury. This condition requires immediate surgical intervention to control the bile leak and prevent chemical peritonitis and sepsis.

Documentation Requirements

✓Evidence of bile in the peritoneal cavity
✓Documentation of underlying biliary pathology (perforation, leak)
✓Imaging studies showing bile collection or leak
✓Surgical intervention to control bile leak source
✓Peritoneal lavage or drainage of bile-contaminated fluid
✓Assessment of gallbladder or bile duct pathology
✓Post-operative management including biliary drainage
✓Monitoring for complications including sepsis

Commonly Confused Codes

K65.0 — Generalized peritonitis (bacterial rather than chemical/bile)K80.00 — Calculus of gallbladder with acute cholecystitis (primary biliary disease)K83.2 — Perforation of bile duct (bile duct pathology rather than peritonitis)T81.31XA — Disruption of external operation wound (post-surgical rather than spontaneous)K87 — Disorders of gallbladder following cholecystectomy (post-surgical complications)
