Parastomal hernia with obstruction, without gangrene

This code signifies a parastomal hernia that has become obstructed, meaning the contents of the hernia sac are trapped, but there is no evidence of tissue death (gangrene). A parastomal hernia is a type of incisional hernia that occurs adjacent to an ostomy site (e.g., colostomy, ileostomy).

Use this code when documentation clearly indicates a patient presents with a parastomal hernia and symptoms of obstruction, such as abdominal pain, distention, nausea, vomiting, or inability to pass stool/flatus, without signs of ischemia or necrosis. Supporting documentation would include physician notes detailing the physical exam findings, imaging reports confirming obstruction, and the absence of gangrenous changes.

• Ensure documentation explicitly states "obstruction" and "without gangrene" to accurately assign this code.
• Do not use this code if gangrene is present; a different code from the K43 category would be more appropriate.
• Sequence this code as the primary diagnosis if the obstruction is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting treatment.
