Diaphragmatic hernia with obstruction, without gangrene

This code signifies a diaphragmatic hernia where a portion of an organ, typically the stomach or intestine, has protruded through an opening in the diaphragm and is causing a blockage or impediment to its normal function. Importantly, there is no evidence of tissue death (gangrene) associated with this obstruction.

Use this code when documentation clearly indicates a diaphragmatic hernia with signs and symptoms of obstruction, such as severe abdominal pain, vomiting, or inability to pass stool, but without any mention of ischemia or gangrenous changes. This applies to both congenital and acquired diaphragmatic hernias that have become obstructed.

• Differentiate from diaphragmatic hernias without obstruction (K44.9) or those with gangrene (K44.1).
• Ensure the medical record explicitly states "obstruction" or provides clinical evidence of blockage.
• Consider sequencing this code as the primary diagnosis if the obstruction is the main reason for the encounter.
