What This Code Means

Inflammation of the peritoneum due to causes not specifically classified elsewhere, such as chemical irritation or other non-infectious sources.

Coding Tips

  • Document the specific cause of peritonitis when possible for more precise coding
  • Review clinical notes to determine if a more specific K65 code applies

Clinical Significance

Other peritonitis represents significant inflammatory conditions requiring immediate attention due to risk of sepsis and abdominal complications. This code impacts risk adjustment as peritoneal inflammation can lead to serious complications requiring intensive medical management and potential surgical intervention.

Documentation Requirements

  • Clear documentation of peritonitis diagnosis
  • Identification of the specific cause (chemical, foreign body, etc.)
  • Evidence ruling out infectious causes
  • Clinical signs and symptoms of peritoneal inflammation
  • Imaging or laboratory findings supporting diagnosis
  • Treatment plan and response to therapy
  • Documentation that condition doesn't fit other specific peritonitis codes
  • Provider assessment of severity and complications
