Other peritonitis

This code signifies inflammation of the peritoneum that is not specifically classified elsewhere. It encompasses various forms of peritonitis that do not fit into more specific categories like generalized peritonitis, peritoneal abscess, or spontaneous bacterial peritonitis. This condition often presents with abdominal pain, tenderness, and signs of infection.

Use this code when documentation specifies peritonitis but lacks further detail to classify it more precisely, or when the type of peritonitis is known but does not have a more specific ICD-10-CM code. Examples include chemical peritonitis due to bile leakage, or peritonitis secondary to a ruptured viscus where the specific cause is not yet fully determined or coded separately. Documentation should clearly state "other peritonitis" or describe a type of peritonitis not covered by more specific codes.

• Do not use this code if a more specific peritonitis code (e.g., K65.0, K65.1, K65.2) is available and supported by documentation.
• Always look for an underlying cause of the peritonitis and code it first if applicable, following sequencing guidelines.
• Ensure documentation differentiates "other peritonitis" from peritoneal abscess (K65.1) or generalized peritonitis (K65.0).
